d38c692f16 perf bpf: Fix bpf prologue generation
Issue:

bpf_probe_read() is no longer available for architecture which has
overlapping address space. Hence bpf prologue generation fails

Fix:

Use bpf_probe_read_kernel for kernel member access. For user attribute
access in kprobes, use bpf_probe_read_user.

Other:

@user attribute was introduced in commit 1e032f7cfa ("perf-probe: Add
user memory access attribute support")

Test:

1. ulimit -l 128 ; ./perf record -e tests/bpf_sched_setscheduler.c
2. cat tests/bpf_sched_setscheduler.c

static void (*bpf_trace_printk)(const char *fmt, int fmt_size, ...) =
        (void *) 6;
static int (*bpf_probe_read_user)(void *dst, __u32 size,
                                  const void *unsafe_ptr) = (void *) 112;
static int (*bpf_probe_read_kernel)(void *dst, __u32 size,
        const void *unsafe_ptr) = (void *) 113;

SEC("func=do_sched_setscheduler  pid policy param->sched_priority@user")
int bpf_func__setscheduler(void *ctx, int err, pid_t pid, int policy,
                           int param)
{
        char fmt[] = "prio: %ld";
        bpf_trace_printk(fmt, sizeof(fmt), param);
        return 1;
}

char _license[] SEC("license") = "GPL";
int _version SEC("version") = LINUX_VERSION_CODE;

3. ./perf script
   sched 305669 [000] 1614458.838675: perf_bpf_probe:func: (2904e508)
   pid=261614 policy=2 sched_priority=1

4. cat /sys/kernel/debug/tracing/trace
   <...>-309956 [006] .... 1616098.093957: 0: prio: 1

Committer testing:

I had to add some missing headers in the bpf_sched_setscheduler.c test
proggie, then instead of using record+script I used 'perf trace' to
drive everything in one go:

  # cat bpf_sched_setscheduler.c
  #include <linux/types.h>
  #include <bpf.h>

  static void (*bpf_trace_printk)(const char *fmt, int fmt_size, ...) = (void *) 6;
  static int (*bpf_probe_read_user)(void *dst, __u32 size, const void *unsafe_ptr) = (void *) 112;
  static int (*bpf_probe_read_kernel)(void *dst, __u32 size, const void *unsafe_ptr) = (void *) 113;

  SEC("func=do_sched_setscheduler  pid policy param->sched_priority@user")
  int bpf_func__setscheduler(void *ctx, int err, pid_t pid, int policy, int param)
  {
          char fmt[] = "prio: %ld";
          bpf_trace_printk(fmt, sizeof(fmt), param);
          return 1;
  }

  char _license[] SEC("license") = "GPL";
  int _version SEC("version") = LINUX_VERSION_CODE;

     0.000 chrt/80125 perf_bpf_probe:func(__probe_ip: -1676607808, policy: 1, sched_priority: 42)

9256c3031e perf probe: Fix user attribute access in kprobes
Issue:

  # perf probe -a 'do_sched_setscheduler pid policy param->sched_priority@user'

did not work before.

Fix:

Make:

  # perf probe -a 'do_sched_setscheduler pid policy param->sched_priority@user'

output equivalent to ftrace:

  # echo 'p:probe/do_sched_setscheduler _text+517384 pid=%r2:s32 policy=%r3:s32 sched_priority=+u0(%r4):s32' > /sys/kernel/debug/tracing/kprobe_events

Other:

1. Right now, __match_glob() does not handle [u]<offset>. For now, use
  *u]<offset>.

2. @user attribute was introduced in commit 1e032f7cfa ("perf-probe:
   Add user memory access attribute support")

Test:
1. perf probe -a 'do_sched_setscheduler  pid policy
   param->sched_priority@user'

2 ./perf script
   sched 305669 [000] 1614458.838675: perf_bpf_probe:func: (2904e508)
   pid=261614 policy=2 sched_priority=1

3. cat /sys/kernel/debug/tracing/trace
   <...>-309956 [006] .... 1616098.093957: 0: prio: 1

Committer testing:

Before:

  # perf probe -a 'do_sched_setscheduler pid policy param->sched_priority@user'
  param(type:sched_param) has no member sched_priority@user.
    Error: Failed to add events.
  # pahole sched_param
  struct sched_param {
  	int                        sched_priority;       /*     0     4 */

  	/* size: 4, cachelines: 1, members: 1 */
  	/* last cacheline: 4 bytes */
  };
  #

After:

  # perf probe -a 'do_sched_setscheduler pid policy param->sched_priority@user'
  Added new event:
    probe:do_sched_setscheduler (on do_sched_setscheduler with pid policy sched_priority=param->sched_priority)

  You can now use it in all perf tools, such as:

  	perf record -e probe:do_sched_setscheduler -aR sleep 1

  # cat /sys/kernel/debug/tracing/kprobe_events
  p:probe/do_sched_setscheduler _text+1113792 pid=%di:s32 policy=%si:s32 sched_priority=+u0(%dx):s32

abfbb29297 remoteproc updates for v5.8
This introduces device managed versions of functions used to register
 remoteproc devices, add support for remoteproc driver specific resource
 control, enables remoteproc drivers to specify ELF class and machine for
 coredumps. It integrates pm_runtime in the core for keeping resources
 active while the remote is booted and holds a wake source while
 recoverying a remote processor after a firmware crash.
 
 It refactors the remoteproc device's allocation path to simplify the
 logic, fix a few cleanup bugs and to not clone const strings onto the
 heap. Debugfs code is simplifies using the DEFINE_SHOW_ATTRIBUTE and a
 zero-length array is replaced with flexible-array.
 
 A new remoteproc driver for the JZ47xx VPU is introduced, the Qualcomm
 SM8250 gains support for audio, compute and sensor remoteprocs and the
 Qualcomm SC7180 modem support is cleaned up and improved.
 
 The Qualcomm glink subsystem-restart driver is merged into the main
 glink driver, the Qualcomm sysmon driver is extended to properly notify
 remote processors about all other remote processors' state transitions.

Merge tag 'rproc-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc

Pull remoteproc updates from Bjorn Andersson:
 "This introduces device managed versions of functions used to register
  remoteproc devices, add support for remoteproc driver specific
  resource control, enables remoteproc drivers to specify ELF class and
  machine for coredumps. It integrates pm_runtime in the core for
  keeping resources active while the remote is booted and holds a wake
  source while recoverying a remote processor after a firmware crash.

  It refactors the remoteproc device's allocation path to simplify the
  logic, fix a few cleanup bugs and to not clone const strings onto the
  heap. Debugfs code is simplifies using the DEFINE_SHOW_ATTRIBUTE and a
  zero-length array is replaced with flexible-array.

  A new remoteproc driver for the JZ47xx VPU is introduced, the Qualcomm
  SM8250 gains support for audio, compute and sensor remoteprocs and the
  Qualcomm SC7180 modem support is cleaned up and improved.

  The Qualcomm glink subsystem-restart driver is merged into the main
  glink driver, the Qualcomm sysmon driver is extended to properly
  notify remote processors about all other remote processors' state
  transitions"

4e3a16ee91 IOMMU Updates for Linux v5.8
Including:
 
 	- A big part of this is a change in how devices get connected to
 	  IOMMUs in the core code. It contains the change from the old
 	  add_device()/remove_device() to the new
 	  probe_device()/release_device() call-backs. As a result
 	  functionality that was previously in the IOMMU drivers has
 	  been moved to the IOMMU core code, including IOMMU group
 	  allocation for each device.
 	  The reason for this change was to get more robust allocation
 	  of default domains for the iommu groups.
 	  A couple of fixes were necessary after this was merged into
 	  the IOMMU tree, but there are no known bugs left. The last fix
 	  is applied on-top of the merge commit for the topic branches.
 
 	- Removal of the driver private domain handling in the Intel
 	  VT-d driver. This was fragile code and I am glad it is gone
 	  now.
 
 	- More Intel VT-d updates from Lu Baolu:
 
 		- Nested Shared Virtual Addressing (SVA) support to the
 		  Intel VT-d driver
 
 		- Replacement of the Intel SVM interfaces to the common
 		  IOMMU SVA API
 
 		- SVA Page Request draining support
 
 	- ARM-SMMU Updates from Will:
 
 		- Avoid mapping reserved MMIO space on SMMUv3, so that
 		  it can be claimed by the PMU driver
 
 		- Use xarray to manage ASIDs on SMMUv3
 
 		- Reword confusing shutdown message
 
 		- DT compatible string updates
 
 		- Allow implementations to override the default domain
 		  type
 
 	- A new IOMMU driver for the Allwinner Sun50i platform
 
 	- Support for ATS gets disabled for untrusted devices (like
 	  Thunderbolt devices). This includes a PCI patch, acked by
 	  Bjorn.
 
 	- Some cleanups to the AMD IOMMU driver to make more use of
 	  IOMMU core features.
 
 	- Unification of some printk formats in the Intel and AMD IOMMU
 	  drivers and in the IOVA code.

Starting from v4.19 commit 29ef680ae7 ("memcg, oom: move out_of_memory
back to the charge path") cgroup oom killer is no longer invoked only
from page faults.  Now it implements the same semantics as global OOM
killer: allocation context invokes OOM killer and keeps retrying until
success.

76b3b58fac asm-generic: improve the flush_dcache_page stub
There is a magic ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE cpp symbol that
guards non-stub availability of flush_dcache_pagge.  Use that to check
if flush_dcache_pagg is implemented.

e0cf615d72 asm-generic: don't include <linux/mm.h> in cacheflush.h
This seems to lead to some crazy include loops when using
asm-generic/cacheflush.h on more architectures, so leave it to the arch
header for now.
