Fix debuginfo__new() to set the build-id to dso before
dso__read_binary_type_filename() so that it can find
DSO_BINARY_TYPE__BUILDID_DEBUGINFO debuginfo correctly.

However, this may not change the result, because elfutils (libdwfl) has
its own debuginfo finder. With/without this patch, the perf probe
correctly find the debuginfo file.

This is just a failsafe and keep code's sanity (if you use
dso__read_binary_type_filename(), you must set the build-id to the dso.)

Recently bperf was added to use BPF to count perf events for various
purposes.  This is an extension for the approach and targetting to
cgroup usages.

Unlike the other bperf, it doesn't share the events with other
processes but it'd reduce unnecessary events (and the overhead of
multiplexing) for each monitored cgroup within the perf session.

When --for-each-cgroup is used with --bpf-counters, it will open
cgroup-switches event per cpu internally and attach the new BPF
program to read given perf_events and to aggregate the results for
cgroups.  It's only called when task is switched to a task in a
different cgroup.

Current 'perf report' fails to process a pipe input when --task or
--stat options are used.  This is because they reset all the tool
callbacks and fails to find a matching event for a sample.

When pipe input is used, the event info is passed via ATTR records so it
needs to handle that operation.  Otherwise the following error occurs.
Note, -14 (= -EFAULT) comes from evlist__parse_sample():

  # perf record -a -o- sleep 1 | perf report -i- --stat

This warning was there to catch any architectures that still use
CONFIG_SET_FS, and that would mis-use iov_iter_init() for anything that
wasn't a proper user space pointer.  So that

        WARN_ON_ONCE(uaccess_kernel());

makes perfect conceptual sense: you really shouldn't use a kernel
pointer with set_fs(KERNEL_DS) and then pass it to iov_iter_init().

HOWEVER.

Guenter Roeck reports that this warning actually triggers in no-mmu
configurations of both ARM and m68k.  And the reason isn't that they
pass in a kernel pointer under set_fs(KERNEL_DS) at all: the reason is
that in those configurations, "uaccess_kernel()" is simply not reliable.

Those no-mmu setups set USER_DS and KERNEL_DS to the same values, so you
can't test for the difference.

In particular, the no-mmu case for ARM does

   #define USER_DS                 KERNEL_DS
   #define uaccess_kernel()        (true)

so USER_DS and KERNEL_DS have the same value, and uaccess_kernel() is
always trivially true.

The m68k case is slightly different and not quite as obvious.  It does
(spread out over multiple header files just to be extra exciting:
asm/processor.h, asm/segment.h and asm-generic/uaccess.h):

   #define TASK_SIZE       (0xFFFFFFFFUL)
   #define USER_DS         MAKE_MM_SEG(TASK_SIZE)
   #define KERNEL_DS       MAKE_MM_SEG(~0UL)
   #define get_fs()        (current_thread_info()->addr_limit)
   #define uaccess_kernel() (get_fs().seg == KERNEL_DS.seg)

but the end result is the same: uaccess_kernel() will always be true,
because USER_DS and KERNEL_DS end up having the same value, even if that
value is defined differently.

This is very arguably a misfeature in those implementations, but in the
end we don't really care.  All modern architectures have gotten rid of
set_fs() already, and generic kernel code never uses it.  And while the
sanity check was a nice idea, an architecture would have to go the extra
mile to actually break this.

So this well-intentioned warning isn't really all that likely to find
anything but these known false positives, and as such just isn't worth
maintaining.

 "Fix arm crashes caused by holes in the memory map.

  The coordination between freeing of unused memory map, pfn_valid() and
  core mm assumptions about validity of the memory map in various ranges
  was not designed for complex layouts of the physical memory with a lot
  of holes all over the place.

  Kefen Wang reported crashes in move_freepages() on a system with the
  following memory layout [1]:

	node 0: [mem 0x0000000080a00000-0x00000000855fffff]
	node 0: [mem 0x0000000086a00000-0x0000000087dfffff]

	node 0: [mem 0x00000000fda00000-0x00000000ffffefff]

  These crashes can be mitigated by enabling CONFIG_HOLES_IN_ZONE on ARM
  and essentially turning pfn_valid_within() to pfn_valid() instead of
  having it hardwired to 1 on that architecture, but this would require
  to keep CONFIG_HOLES_IN_ZONE solely for this purpose.

  A cleaner approach is to update ARM's implementation of pfn_valid() to
  take into accounting rounding of the freed memory map to pageblock
  boundaries and make sure it returns true for PFNs that have memory map
  entries even if there is no physical memory backing those PFNs"

Pull CXL (Compute Express Link) updates from Dan Williams:
 "This subsystem is still in the build-out phase as the bulk of the
  update is improvements to enumeration and fleshing out the device
  model. In terms of new features, more mailbox commands have been added
  to the allowed-list in support of persistent memory provisioning
  support targeting v5.15.

  The critical update from an enumeration perspective is support for the
  CXL Fixed Memory Window Structure that indicates to Linux which system
  physical address ranges decode to the CXL Host Bridges in the system.
  This allows the driver to detect which address ranges have been mapped
  by firmware and what address ranges are available for future hotplug.

  So, again, mostly skeleton this round, with more meat targeting v5.15.

  Summary:

   - Add support for the CXL Fixed Memory Window Structure, a recent
     extension of the ACPI CEDT (CXL Early Discovery Table)

   - Add infrastructure for component registers

   - Add HDM (Host-managed device memory) decoder definitions

   - Define a device model for an HDM decoder tree

   - Bridge CXL persistent memory capabilities to an NVDIMM bus /
     device-model

   - Switch to fine grained mapping of CXL MMIO registers to allow

Commit d2bcbeab ("scsi: blkcg: Add app identifier support for
blkcg") introduced an FC_APPID config option under SCSI. However, the
added config option is not used anywhere. Simply remove it.

The block layer BLK_CGROUP_FC_APPID config option is what actually
controls whether the application ID code should be built or not. Make
this option dependent on NVMe over FC since that is currently the only
transport which supports the capability.

Pull tracing updates from Steven Rostedt:

 - Added option for per CPU threads to the hwlat tracer

 - Have hwlat tracer handle hotplug CPUs

 - New tracer: osnoise, that detects latency caused by interrupts,
   softirqs and scheduling of other tasks.

 - Added timerlat tracer that creates a thread and measures in detail
   what sources of latency it has for wake ups.

 - Removed the "success" field of the sched_wakeup trace event. This has
   been hardcoded as "1" since 2015, no tooling should be looking at it
   now. If one exists, we can revert this commit, fix that tool and try
   to remove it again in the future.

 - tgid mapping fixed to handle more than PID_MAX_DEFAULT pids/tgids.

 - New boot command line option "tp_printk_stop", as tp_printk causes
   trace events to write to console. When user space starts, this can
   easily live lock the system. Having a boot option to stop just after
   boot up is useful to prevent that from happening.

 - Have ftrace_dump_on_oops boot command line option take numbers that
   match the numbers shown in /proc/sys/kernel/ftrace_dump_on_oops.

 - Bootconfig clean ups, fixes and enhancements.

 - New ktest script that tests bootconfig options.

   without triggering a WARN*() if it already exists. BPF has a path
   from user space that can do this. All other paths are considered a

This reverts commit 9ce650a7.

This commit causes watchdog lockups on my machine, and while I have no
idea what the cause is, it bisected right to this commit, and reverting
the change promptly fixes it.

At least occasionally one of the watchdog call traces was

  Call Trace:
    _raw_spin_lock_irqsave+0x35/0x40
    snd_pcm_period_elapsed+0x1b/0xa0 [snd_pcm]
    snd_usb_endpoint_start+0x1a0/0x3c0 [snd_usb_audio]
    start_endpoints+0x23/0x90 [snd_usb_audio]
    snd_usb_substream_playback_trigger+0x7b/0x1a0 [snd_usb_audio]
    snd_pcm_common_ioctl+0x1c44/0x2360 [snd_pcm]
    snd_pcm_ioctl+0x2e/0x40 [snd_pcm]
    __se_sys_ioctl+0x72/0xc0
    do_syscall_64+0x4c/0xa0
    entry_SYSCALL_64_after_hwframe+0x44/0xae

so presumably it's a locking error on that substream spinlock that
snd_pcm_period_elapsed() takes.  But at this point I just want to have a
working system so that I can continue the merge window work tomorrow.

Pull xfs updates from Darrick Wong:
 "Most of the work this cycle has been on refactoring various parts of
  the codebase. The biggest non-cleanup changes are (1) reducing the
  number of cache flushes sent when writing the log; (2) a substantial
  number of log recovery fixes; and (3) I started accepting pull
  requests from contributors if the commits in their branches match
  what's been sent to the list.

  For a week or so I /had/ staged a major cleanup of the logging code
  from Dave Chinner, but it exposed so many lurking bugs in other parts
  of the logging and log recovery code that I decided to defer that
  patchset until we can address those latent bugs.

  Larger cleanups this time include walking the incore inode cache (me)
  and rework of the extended attribute code (Allison) to prepare it for
  adding logged xattr updates (and directory tree parent pointers) in
  future releases.

  Summary:

   - Refactor the buffer cache to use bulk page allocation

   - Convert agnumber-based AG iteration to walk per-AG structures

   - Clean up some unit conversions and other code warts

   - Reduce spinlock contention in the directio fastpath

   - Collapse all the inode cache walks into a single function

   - Remove indirect function calls from the inode cache walk code

   - Dramatically reduce the number of cache flushes sent when writing
     log buffers

   - Preserve inode sickness reports for longer

   - Rename xfs_eofblocks since it controls inode cache walks

   - Refactor the extended attribute code to prepare it for the addition
     of log intent items to make xattrs fully transactional

   - A few fixes to earlier large patchsets

   - Log recovery fixes so that we don't accidentally mark the log clean
     when log intent recovery fails

   - Fix some latent SOB errors

   - Clean up shutdown messages that get logged to dmesg

   - Fix a regression in the online shrink code

   - Fix a UAF in the buffer logging code if the fs goes offline

   - Fix uninitialized error variables

   - Fix a UAF in the CIL when commited log item callbacks race with a
     shutdown

   - Fix a bug where the CIL could hang trying to push part of the log
     ring buffer that hasn't been filled yet"

Merge tag 'asm-generic-unaligned-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic

Pull asm/unaligned.h unification from Arnd Bergmann:
 "Unify asm/unaligned.h around struct helper

  The get_unaligned()/put_unaligned() helpers are traditionally
  architecture specific, with the two main variants being the
  "access-ok.h" version that assumes unaligned pointer accesses always
  work on a particular architecture, and the "le-struct.h" version that
  casts the data to a byte aligned type before dereferencing, for
  architectures that cannot always do unaligned accesses in hardware.

  Based on the discussion linked below, it appears that the access-ok
  version is not realiable on any architecture, but the struct version
  probably has no downsides. This series changes the code to use the
  same implementation on all architectures, addressing the few
  exceptions separately"

Pull perf tool updates from Arnaldo Carvalho de Melo:
 "Tools:

   - Add cgroup support for 'perf top' (-G).

   - Add support for KVM MSRs in 'perf kvm stat'

   - Support probes on init functions in 'perf probe', to support the
     bootconfig format.

   - Improve error reporting in 'perf probe'.

   - No need to synthesize BUILD_ID records in 'perf inject' if the
     MMAP2 records have build ids already.

   - Allow toggling source code ('s' hotkey) in 'perf annotate' in all
     lines.

   - Add itrace options support to 'perf annotate'.

   - Support to custom DSO filters for 'perf script'.

  Hardware enablement:

   - Support the HYBRID_TOPOLOGY and HYBRID_CPU_PMU_CAPS features in the
     perf.data file header.

   - Support PMU prefix for mem-load and mem-store events, to support
     hybrid (BIG little) CPUs such as Intel's Alderlake.

   - Support hybrid CPUs in 'perf mem' and 'perf c2c'.

  Hardware tracing:

   - Intel PT now supports tracing KVM guests.

   - Timestamp improvements for ARM's Coresight.

  Build:

   - Add 'make -C tools/perf build-test' entries for
     libopencsd/CORESIGHT=1 and libbpf/LIBBPF_DYNAMIC=1.

   - Use bison's --file-prefix-map option to avoid storing full paths
     when using O= in the perf build.

  Tests:

   - Improve the 'perf test' entries for libpfm4 and BPF counters.

  Misc:

   - Sync msr-index.h, mount.h, kvm headers with the kernel originals.

   - Add vendor events and metrics for Intel's Icelake Server & Client"
