mm/memory_hotplug: add pgprot_t to mhp_params
devm_memremap_pages() is currently used by the PCI P2PDMA code to create struct page mappings for IO memory. At present, these mappings are created with PAGE_KERNEL which implies setting the PAT bits to be WB. However, on x86, an mtrr register will typically override this and force the cache type to be UC-. In the case firmware doesn't set this register it is effectively WB and will typically result in a machine check exception when it's accessed. Other arches are not currently likely to function correctly seeing they don't have any MTRR registers to fall back on. To solve this, provide a way to specify the pgprot value explicitly to arch_add_memory(). Of the arches that support MEMORY_HOTPLUG: x86_64, and arm64 need a simple change to pass the pgprot_t down to their respective functions which set up the page tables. For x86_32, set the page tables explicitly using _set_memory_prot() (seeing they are already mapped). For ia64, s390 and sh, reject anything but PAGE_KERNEL settings -- this should be fine, for now, seeing these architectures don't support ZONE_DEVICE. A check in __add_pages() is also added to ensure the pgprot parameter was set for all arches.

mm/vma: introduce VM_ACCESS_FLAGS
There are many places where all basic VMA access flags (read, write, exec) are initialized or checked against as a group. One such example is during page fault. Existing vma_is_accessible() wrapper already creates the notion of VMA accessibility as a group access permissions. Hence lets just create VM_ACCESS_FLAGS (VM_READ|VM_WRITE|VM_EXEC) which will not only reduce code duplication but also extend the VMA accessibility concept in general.

mm/vma: define a default value for VM_DATA_DEFAULT_FLAGS
There are many platforms with exact same value for VM_DATA_DEFAULT_FLAGS This creates a default value for VM_DATA_DEFAULT_FLAGS in line with the existing VM_STACK_DEFAULT_FLAGS. While here, also define some more macros with standard VMA access flag combinations that are used frequently across many platforms. Apart from simplification, this reduces code duplication as well.

arm64: armv8_deprecated: Fix undef_hook mask for thumb setend
For thumb instructions, call_undef_hook() in traps.c first reads a u16,
and if the u16 indicates a T32 instruction (u16 >= 0xe800), a second
u16 is read, which then makes up the the lower half-word of a T32
instruction. For T16 instructions, the second u16 is not read,
which makes the resulting u32 opcode always have the upper half set to
0.
However, having the upper half of instr_mask in the undef_hook set to 0
masks out the upper half of all thumb instructions - both T16 and T32.
This results in trapped T32 instructions with the lower half-word equal
to the T16 encoding of setend (b650) being matched, even though the upper
half-word is not 0000 and thus indicates a T32 opcode.
An example of such a T32 instruction is eaa0b650, which should raise a
SIGILL since T32 instructions with an eaa prefix are unallocated as per
Arm ARM, but instead works as a SETEND because the second half-word is set
to b650.
This patch fixes the issue by extending instr_mask to include the
upper u32 half, which will still match T16 instructions where the upper
half is 0, but not T32 instructions.

mm: allow VM_FAULT_RETRY for multiple times
The idea comes from a discussion between Linus and Andrea [1]. Before this patch we only allow a page fault to retry once. We achieved this by clearing the FAULT_FLAG_ALLOW_RETRY flag when doing handle_mm_fault() the second time. This was majorly used to avoid unexpected starvation of the system by looping over forever to handle the page fault on a single page. However that should hardly happen, and after all for each code path to return a VM_FAULT_RETRY we'll first wait for a condition (during which time we should possibly yield the cpu) to happen before VM_FAULT_RETRY is really returned. This patch removes the restriction by keeping the FAULT_FLAG_ALLOW_RETRY flag when we receive VM_FAULT_RETRY. It means that the page fault handler now can retry the page fault for multiple times if necessary without the need to generate another page fault event. Meanwhile we still keep the FAULT_FLAG_TRIED flag so page fault handler can still identify whether a page fault is the first attempt or not. Then we'll have these combinations of fault flags (only considering ALLOW_RETRY flag and TRIED flag): - ALLOW_RETRY and !TRIED: this means the page fault allows to retry, and this is the first try - ALLOW_RETRY and TRIED: this means the page fault allows to retry, and this is not the first try - !ALLOW_RETRY and !TRIED: this means the page fault does not allow to retry at all - !ALLOW_RETRY and TRIED: this is forbidden and should never be used In existing code we have multiple places that has taken special care of the first condition above by checking against (fault_flags & FAULT_FLAG_ALLOW_RETRY). This patch introduces a simple helper to detect the first retry of a page fault by checking against both (fault_flags & FAULT_FLAG_ALLOW_RETRY) and !(fault_flag & FAULT_FLAG_TRIED) because now even the 2nd try will have the ALLOW_RETRY set, then use that helper in all existing special paths. One example is in __lock_page_or_retry(), now we'll drop the mmap_sem only in the first attempt of page fault and we'll keep it in follow up retries, so old locking behavior will be retained. This will be a nice enhancement for current code [2] at the same time a supporting material for the future userfaultfd-writeprotect work, since in that work there will always be an explicit userfault writeprotect retry for protected pages, and if that cannot resolve the page fault (e.g., when userfaultfd-writeprotect is used in conjunction with swapped pages) then we'll possibly need a 3rd retry of the page fault. It might also benefit other potential users who will have similar requirement like userfault write-protection. GUP code is not touched yet and will be covered in follow up patch.

mm: introduce FAULT_FLAG_DEFAULT
Although there're tons of arch-specific page fault handlers, most of them are still sharing the same initial value of the page fault flags. Say, merely all of the page fault handlers would allow the fault to be retried, and they also allow the fault to respond to SIGKILL. Let's define a default value for the fault flags to replace those initial page fault flags that were copied over. With this, it'll be far easier to introduce new fault flag that can be used by all the architectures instead of touching all the archs.

asm-generic: make more kernel-space headers mandatory
Change a header to mandatory-y if both of the following are met: [1] At least one architecture (except um) specifies it as generic-y in arch/*/include/asm/Kbuild [2] Every architecture (except um) either has its own implementation (arch/*/include/asm/*.h) or specifies it as generic-y in arch/*/include/asm/Kbuild This commit was generated by the following shell script. ----------------------------------->8----------------------------------- arches=$(cd arch; ls -1 | sed -e '/Kconfig/d' -e '/um/d') tmpfile=$(mktemp) grep "^mandatory-y +=" include/asm-generic/Kbuild > $tmpfile find arch -path 'arch/*/include/asm/Kbuild' | xargs sed -n 's/^generic-y += \(.*\)/\1/p' | sort -u | while read header do mandatory=yes for arch in $arches do if ! grep -q "generic-y += $header" arch/$arch/include/asm/Kbuild && !

So, mandatory-y works like a fallback default (by just wrapping asm-generic one) when arch does not have a specific header implementation. See the following commits: |

arm64: remove CONFIG_DEBUG_ALIGN_RODATA feature
When CONFIG_DEBUG_ALIGN_RODATA is enabled, kernel segments mapped with different permissions (r-x for .text, r-- for .rodata, rw- for .data, etc) are rounded up to 2 MiB so they can be mapped more efficiently. In particular, it permits the segments to be mapped using level 2 block entries when using 4k pages, which is expected to result in less TLB pressure. However, the mappings for the bulk of the kernel will use level 2 entries anyway, and the misaligned fringes are organized such that they can take advantage of the contiguous bit, and use far fewer level 3 entries than would be needed otherwise. This makes the value of this feature dubious at best, and since it is not enabled in defconfig or in the distro configs, it does not appear to be in wide use either. So let's just remove it.

arm64: Always force a branch protection mode when the compiler has one
Compilers with branch protection support can be configured to enable it by
default, it is likely that distributions will do this as part of deploying
branch protection system wide. As well as the slight overhead from having
some extra NOPs for unused branch protection features this can cause more
serious problems when the kernel is providing pointer authentication to
userspace but not built for pointer authentication itself. In that case our
switching of keys for userspace can affect the kernel unexpectedly, causing
pointer authentication instructions in the kernel to corrupt addresses.
To ensure that we get consistent and reliable behaviour always explicitly
initialise the branch protection mode, ensuring that the kernel is built
the same way regardless of the compiler defaults.
Fixes:

vhost: refine vhost and vringh kconfig
Currently, CONFIG_VHOST depends on CONFIG_VIRTUALIZATION. But vhost is not necessarily for VM since it's a generic userspace and kernel communication protocol. Such dependency may prevent archs without virtualization support from using vhost. To solve this, a dedicated vhost menu is created under drivers so CONIFG_VHOST can be decoupled out of CONFIG_VIRTUALIZATION. While at it, also squash Kconfig.vringh into vhost Kconfig file. This avoids the trick of conditional inclusion from VOP or CAIF. Then it will be easier to introduce new vringh users and common dependency for both vringh and vhost.

arm64: Kconfig: ptrauth: Add binutils version check to fix mismatch
Recent addition of ARM64_PTR_AUTH exposed a mismatch issue with binutils.
9.1+ versions of gcc inserts a section note .note.gnu.property but this
can be used properly by binutils version greater than 2.33.1. If older
binutils are used then the following warnings are generated,
aarch64-linux-ld: warning: arch/arm64/kernel/vdso/vgettimeofday.o: unsupported GNU_PROPERTY_TYPE (5) type: 0xc0000000
aarch64-linux-objdump: warning: arch/arm64/lib/csum.o: unsupported GNU_PROPERTY_TYPE (5) type: 0xc0000000
aarch64-linux-nm: warning: .tmp_vmlinux1: unsupported GNU_PROPERTY_TYPE (5) type: 0xc0000000
This patch enables ARM64_PTR_AUTH when gcc and binutils versions are
compatible with each other. Older gcc which do not insert such section
continue to work as before.
This scenario may not occur with clang as a recent commit

The low level functions cpu_up/down() are now confined to the core code and not longer accessible from random code. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl6B9VQTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYodCyD/0WFYAe7LkOfNjkbLa0IeuyLjF9rnCi ilcSXMLpaVwwoQvm7MopwkXUDdmEIyeJ0B641j3mC3AKCRap4+O36H2IEg2byrj7 twOvQNCfxpVVmCCD11FTH9aQa74LEB6AikTgjevhrRWj6eHsal7c2Ak26AzCgrt+ 0eEkOAOWJbLAlbIiPdHlCZ3TMldcs3gg+lRSYd5QCGQVkZFnwpXzyOvpyJEUGGbb R/JuvwJoLhRMiYAJDILoQQQg/J07ODuivse/R8PWaH2djkn+2NyRGrD794PhyyOg QoTU0ZrYD3Z48ACXv+N3jLM7wXMcFzjYtr1vW1E3O/YGA7GVIC6XHGbMQ7tEihY0 ajtwq8DcnpKtuouviYnf7NuKgqdmJXkaZjz3Gms6n8nLXqqSVwuQELWV2CXkxNe6 9kgnnKK+xXMOGI4TUhN8bejvkXqRCmKMeQJcWyf+7RA9UIhAJw5o7WGo8gXfQWUx tazCqDy/inYjqGxckW615fhi2zHfemlYTbSzIGOuMB1TEPKFcrgYAii/VMsYHQVZ 5amkYUXGQ5brlCOzOn38lzp5OkALBnFzD7xgvOcQgWT3ynVpdqADfBytXiEEHh4J KSkSgSSRcS58397nIxnDcJgJouHLvAWYyPZ4UC6mfynuQIic31qMHGVqwdbEKMY3 4M5dGgqIfOBgYw== =jwCg -----END PGP SIGNATURE----- Merge tag 'smp-core-2020-03-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull core SMP updates from Thomas Gleixner: "CPU (hotplug) updates: - Support for locked CSD objects in smp_call_function_single_async() which allows to simplify callsites in the scheduler core and MIPS - Treewide consolidation of CPU hotplug functions which ensures the consistency between the sysfs interface and kernel state.

Merge branch 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull scheduler updates from Ingo Molnar: "The main changes in this cycle are: - Various NUMA scheduling updates: harmonize the load-balancer and NUMA placement logic to not work against each other. The intended result is better locality, better utilization and fewer migrations. - Introduce Thermal Pressure tracking and optimizations, to improve task placement on thermally overloaded systems. - Implement frequency invariant scheduler accounting on (some) x86 CPUs. This is done by observing and sampling the 'recent' CPU frequency average at ~tick boundaries. The CPU provides this data via the APERF/MPERF MSRs. This hopefully makes our capacity estimates more precise and keeps tasks on the same CPU better even if it might seem overloaded at a lower momentary frequency. (As usual, turbo mode is a complication that we resolve by observing the maximum frequency and renormalizing to it.) - Add asymmetric CPU capacity wakeup scan to improve capacity utilization on asymmetric topologies. (big.LITTLE systems) - PSI fixes and optimizations. - RT scheduling capacity awareness fixes & improvements. - Optimize the CONFIG_RT_GROUP_SCHED constraints code. - Misc fixes, cleanups and optimizations - see the changelog for details" * 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (62 commits) threads: Update PID limit comment according to futex UAPI change sched/fair: Fix condition of avg_load calculation sched/rt: cpupri_find: Trigger a full search as fallback kthread: Do not preempt current task if it is going to call schedule() sched/fair: Improve spreading of utilization sched: Avoid scale real weight down to zero psi: Move PF_MEMSTALL out of task->flags MAINTAINERS: Add maintenance information for psi psi: Optimize switching tasks inside shared cgroups psi: Fix cpu.pressure for cpu.max and competing cgroups sched/core: Distribute tasks within affinity masks sched/fair: Fix enqueue_task_fair warning thermal/cpu-cooling, sched/core: Move the arch_set_thermal_pressure() API to generic scheduler code sched/rt: Remove unnecessary push for unfit tasks sched/rt: Allow pulling unfitting task sched/rt: Optimize cpupri_find() on non-heterogenous systems sched/rt: Re-instate old behavior in select_task_rq_rt() sched/rt: cpupri_find: Implement fallback mechanism for !fit case sched/fair: Fix reordering of enqueue/dequeue_task_fair() sched/fair: Fix runnable_avg for throttled cfs ... |

Pull EFI updates from Ingo Molnar: "The EFI changes in this cycle are much larger than usual, for two (positive) reasons: - The GRUB project is showing signs of life again, resulting in the introduction of the generic Linux/UEFI boot protocol, instead of x86 specific hacks which are increasingly difficult to maintain. There's hope that all future extensions will now go through that boot protocol. - Preparatory work for RISC-V EFI support. The main changes are: - Boot time GDT handling changes - Simplify handling of EFI properties table on arm64 - Generic EFI stub cleanups, to improve command line handling, file I/O, memory allocation, etc. - Introduce a generic initrd loading method based on calling back into the firmware, instead of relying on the x86 EFI handover protocol or device tree. - Introduce a mixed mode boot method that does not rely on the x86 EFI handover protocol either, and could potentially be adopted by other architectures (if another one ever surfaces where one execution mode is a superset of another) - Clean up the contents of 'struct efi', and move out everything that doesn't need to be stored there. - Incorporate support for UEFI spec v2.8A changes that permit firmware implementations to return EFI_UNSUPPORTED from UEFI runtime services at OS runtime, and expose a mask of which ones are supported or unsupported via a configuration table. - Partial fix for the lack of by-VA cache maintenance in the decompressor on 32-bit ARM. - Changes to load device firmware from EFI boot service memory regions - Various documentation updates and minor code cleanups and fixes" * 'efi-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (114 commits) efi/libstub/arm: Fix spurious message that an initrd was loaded efi/libstub/arm64: Avoid image_base value from efi_loaded_image partitions/efi: Fix partition name parsing in GUID partition entry efi/x86: Fix cast of image argument efi/libstub/x86: Use ULONG_MAX as upper bound for all allocations efi: Fix a mistype in comments mentioning efivar_entry_iter_begin() efi/libstub: Avoid linking libstub/lib-ksyms.o into vmlinux efi/x86: Preserve %ebx correctly in efi_set_virtual_address_map() efi/x86: Ignore the memory attributes table on i386 efi/x86: Don't relocate the kernel unless necessary efi/x86: Remove extra headroom for setup block efi/x86: Add kernel preferred address to PE header efi/x86: Decompress at start of PE image load address x86/boot/compressed/32: Save the output address instead of recalculating it efi/libstub/x86: Deal with exit() boot service returning x86/boot: Use unsigned comparison for addresses efi/x86: Avoid using code32_start efi/x86: Make efi32_pe_entry() more readable efi/x86: Respect 32-bit ABI in efi32_pe_entry() efi/x86: Annotate the LOADED_IMAGE_PROTOCOL_GUID with SYM_DATA ... |

futex: arch_futex_atomic_op_inuser() calling conventions change
Move access_ok() in and pagefault_enable()/pagefault_disable() out. Mechanical conversion only - some instances don't really need a separate access_ok() at all (e.g. the ones only using get_user()/put_user(), or architectures where access_ok() is always true); we'll deal with that in followups.

ARM: DT and driver fixes for v5.6
For the devicetree files, there are a total of 20 patches, almost entirely for 32-bit machines: - The Allwinner/sun9i r40 SoC dtsi file contains a number of issues, both for correctness and for style that are addressed in separate patches. This causes most of the changed lines of the DT updates this time. - More Allwinner updates fixing the identification of the security system on sun8i/A33, a recent regression of the A83t ethernet, and a few board specific issues on the TBS-A711 macine. - Several bug fixes for OMAP dts files, most notably fixing the timings for the NAND flash on the Nokia N900 that regressed a while ago after the move to configuring them from DT. Some other OMAPs now set the correct dma limits on the L3 bus, and a regression fix addresses lost Ethernet on dm814x - One incorrect setting in the newly added Raspberry Pi Zero W that may cause issues with the SD card controller. - A missing property on the bcm2835 firmware node caused incorrect DMA settings. - An old bug on the oxnas platform causing spurious interrupts is finally addressed. - A regression on the Exynos Midas board broke the OLED panel power supply. - The i.MX6 phycore SoM specified the wrong voltage for the SoC, this is now set to the values from the datasheet. - Some 64-bit machines use a deprecated string to identify the PSCI firmware. There are also several small code fixes addressing mostly serious issues: - Fix the sunxi rsb bus access to no longer return incorrect data when mixing 8 and 16 bit I/O. - Fix a suspend/resume regression on the OMAP2+ lcdc from a missing quirk in the ti-sysc driver - Fix a NULL pointer access from a race in the fsl dpio driver - Fix a v5.5 regression in the exynos-chipid driver that caused an invalid error code probing the device on non-exynos platforms - Fix an out-of-bounds access in the AMD TEE driver -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAl5+LG0ACgkQmmx57+YA GNkZhhAAtWTv4sRf2faVzjAngWTs1LXuVpoX8UT2JXOMvY20Y1tQ6YzH8bkJahIr oqPsEFOANkDGON+72+7YCFUVuT2rle9xPLUpdCv3F1Q3TAP8jslkvI/7tK21UKnG OAsMaJdKeKg4yK+KJnh7OtOBvSJzJ0YUU8BCFs8rsSeTkMdPDz74YbC+jV974SVD eCYj/Nih/wt1tG+q/W0tk0LdUtAsgQWbn3WFOrbQ0SSu8i+SVbulBc2oLsltO7VX TFhSRimPAhxGcHJcCoD/enNuHGwKWFkGdQ7jGU3138ZP4PUztNMYKVgZmeUAH1m1 HXlZkpCSIDUjydEAPFJPJMGJumoKvPIf9kwq9f0ceukR8DKWW3suq/gl6C/AJcHE K21ofuYftFZ13QXI3khv9SaBKSesEZ1qCVOj4jHNwunAjOc2+sNHdceO4rlD+N5M xyIG/U3rO/6VOO7ex32q39x8vCDu2TFi4nxTPQTKIslKj55DgWLayhIyBPiEyo0R UMopcoBOrw9LL2AA+ugTHU9CyXW1G3CMsUY/V+i2sZLElsJuVL3kvWaudttXzjei O3yV9J8MNTTCPyN981nu+iBAoanqbRP+JZJf0dC2kj+fjB3N9Q8Bziy6XmN3P9Kv 7qvuSmG5YN3bc3oQKlaUPUWJVqYnsYVEjWh2SqhOmLn5WhK6F5c= =31+Z -----END PGP SIGNATURE----- Merge tag 'arm-soc-fixes-5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM DT and driver fixes from Arnd Bergmann: "For the devicetree files, there are a total of 20 patches, almost entirely for 32-bit machines: - The Allwinner/sun9i r40 SoC dtsi file contains a number of issues, both for correctness and for style that are addressed in separate patches.
