Entering and exiting SMM may require ISA specific handling under certain
circumstances. This commit adds two new callbacks with empty implementations.
Actual functionality will be added in following commits.
* pre_enter_smm() is to be called when injecting an SMM, before any
SMM related vcpu state has been changed
* pre_leave_smm() is to be called when emulating the RSM instruction,
when the vcpu is in real mode and before any SMM related vcpu state
has been restored

It has always annoyed me a bit how SVM_EXIT_NPF is handled by
pf_interception. This is also the only reason behind the
under-documented need_unprotect argument to kvm_handle_page_fault.
Let NPF go straight to kvm_mmu_page_fault, just like VMX
does in handle_ept_violation and handle_ept_misconfig.

Checking the mode is unnecessary, and is done without a memory barrier
separating the LAPIC write from the vcpu->mode read; in addition,
kvm_vcpu_wake_up is already doing a check for waiters on the wait queue
that has the same effect.
In practice it's safe because spin_lock has full-barrier semantics on x86,
but don't be too clever.

SDM mentioned:
"If either the “unrestricted guest†VM-execution control or the “mode-based
execute control for EPT†VM- execution control is 1, the “enable EPTâ€
VM-execution control must also be 1."
However, we can still observe unrestricted_guest is Y after inserting the kvm-intel.ko
w/ ept=N. It depends on later starts a guest in order that the function
vmx_compute_secondary_exec_control() can be executed, then both the module parameter
and exec control fields will be amended.
This patch fixes it by amending module parameter immediately during vmcs data setup.

The kvm slabs can consume a significant amount of system memory
and indeed in our production environment we have observed that
a lot of machines are spending significant amount of memory that
can not be left as system memory overhead. Also the allocations
from these slabs can be triggered directly by user space applications
which has access to kvm and thus a buggy application can leak
such memory. So, these caches should be accounted to kmemcg.

The description in the Intel SDM of how the divide configuration
register is used: "The APIC timer frequency will be the processor's bus
clock or core crystal clock frequency divided by the value specified in
the divide configuration register."
Observation of baremetal shown that when the TDCR is change, the TMCCT
does not change or make a big jump in value, but the rate at which it
count down change.
The patch update the emulation to APIC timer to so that a change to the
divide configuration would be reflected in the value of the counter and
when the next interrupt is triggered.

Signed-off-by: Radim Krčmář <rkrcmar@redhat.com>
If we take TSC-deadline mode timer out of the picture, the Intel SDM
does not say that the timer is disable when the timer mode is change,
either from one-shot to periodic or vice versa.
After this patch, the timer is no longer disarmed on change of mode, so
the counter (TMCCT) keeps counting down.
So what does a write to LVTT changes ? On baremetal, the change of mode
is probably taken into account only when the counter reach 0. When this
happen, LVTT is use to figure out if the counter should restard counting
down from TMICT (so periodic mode) or stop counting (if one-shot mode).
This patch is based on observation of the behavior of the APIC timer on
baremetal as well as check that they does not go against the description
written in the Intel SDM.

When KVM emulates an exit from L2 to L1, it loads L1 CR4 into the
guest CR4. Before this CR4 loading, the guest CR4 refers to L2
CR4. Because these two CR4's are in different levels of guest, we
should vmx_set_cr4() rather than kvm_set_cr4() here. The latter, which
is used to handle guest writes to its CR4, checks the guest change to
CR4 and may fail if the change is invalid.
The failure may cause trouble. Consider we start
a L1 guest with non-zero L1 PCID in use,
(i.e. L1 CR4.PCIDE == 1 && L1 CR3.PCID != 0)
and
a L2 guest with L2 PCID disabled,
(i.e. L2 CR4.PCIDE == 0)
and following events may happen:
1. If kvm_set_cr4() is used in load_vmcs12_host_state() to load L1 CR4
into guest CR4 (in VMCS01) for L2 to L1 exit, it will fail because
of PCID check. As a result, the guest CR4 recorded in L0 KVM (i.e.
vcpu->arch.cr4) is left to the value of L2 CR4.
2. Later, if L1 attempts to change its CR4, e.g., clearing VMXE bit,
kvm_set_cr4() in L0 KVM will think L1 also wants to enable PCID,
because the wrong L2 CR4 is used by L0 KVM as L1 CR4. As L1
CR3.PCID != 0, L0 KVM will inject GP to L1 guest.

is_last_gpte() is not equivalent to the pseudo-code given in commit
6bb69c9b69 ("KVM: MMU: simplify last_pte_bitmap") because an incorrect
value of last_nonleaf_level may override the result even if level == 1.
It is critical for is_last_gpte() to return true on level == 1 to
terminate page walks. Otherwise memory corruption may occur as level
is used as an index to various data structures throughout the page
walking code. Even though the actual bug would be wherever the MMU is
initialized (as in the previous patch), be defensive and ensure here
that is_last_gpte() returns the correct value.
This patch is also enough to fix CVE-2017-12188.

Pull block fixes from Jens Axboe:
"A collection of fixes for this series. This contains:
- NVMe pull request from Christoph, one uuid attribute fix, and one
fix for the controller memory buffer address for remapped BARs.
- use-after-free fix for bsg, from Benjamin Block.
- bcache race/use-after-free fix for a list traversal, fixing a
regression in this merge window. From Coly Li.
- null_blk change configfs dependency change from a 'depends' to a
'select'. This is a change from this merge window as well. From me.
- nbd signal fix from Josef, fixing a regression introduced with the
status code changes.
- nbd MAINTAINERS mailing list entry update.
- blk-throttle stall fix from Joseph Qi.
- blk-mq-debugfs fix from Omar, fixing an issue where we don't
register the IO scheduler debugfs directory, if the driver is
loaded with it. Only shows up if you switch through the sysfs
interface"
* 'for-linus' of git://git.kernel.dk/linux-block:
bsg-lib: fix use-after-free under memory-pressure
nvme-pci: Use PCI bus address for data/queues in CMB
blk-mq-debugfs: fix device sched directory for default scheduler
null_blk: change configfs dependency to select
blk-throttle: fix possible io stall when upgrade to max
MAINTAINERS: update list for NBD
nbd: fix -ERESTARTSYS handling
nvme: fix visibility of "uuid" ns attribute
bcache: use llist_for_each_entry_safe() in __closure_wake_up()
- Bring initialisation of user space undefined instruction handling
early (core_initcall) since late_initcall() happens after modprobe in
initramfs is invoked. Similar fix for fpsimd initialisation
- Increase the kernel stack when KASAN is enabled
- Bring the PCI ACS enabling earlier via the
iort_init_platform_devices()
- Fix misleading data abort address printing (decimal vs hex)

request, so only if some new issues are discovered in the remainder of
the rc cycles will you hear from me again.
Summary:
- a fix for iwpm netlink usage

Pull btrfs fixes from David Sterba:
"Two more fixes for bugs introduced in 4.13.
The sector_t problem with 32bit architecture and !LBDAF config seems
serious but the number of affected deployments is hopefully low.
The clashing status bits could lead to a confusing in-memory state of
the whole-filesystem operations if used with the quota override sysfs
knob"
* 'for-4.14-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
Btrfs: fix overlap of fs_info::flags values
btrfs: avoid overflow when sector_t is 32 bit
