Pull probe fixes from Masami Hiramatsu:

 - fprobe: Add a comment why fprobe will be skipped if another kprobe is
   running in fprobe_kprobe_handler().

 - probe-events: Fix some issues related to fetch-arguments:

    - Fix double counting of the string length for user-string and
      symstr. This will require longer buffer in the array case.

    - Fix not to count error code (minus value) for the total used
      length in array argument. This makes the total used length
      shorter.

    - Fix to update dynamic used data size counter only if fetcharg uses
      the dynamic size data. This may mis-count the used dynamic data
      size and corrupt data.

    - Revert "tracing: Add "(fault)" name injection to kernel probes"
      because that did not work correctly with a bug, and we agreed the
      current '(fault)' output (instead of '"(fault)"' like a string)
      explains what happened more clearly.

    - Fix to record 0-length (means fault access) data_loc data in fetch
      function itself, instead of store_trace_args(). If we record an
      array of string, this will fix to save fault access data on each
      entry of the array correctly.

Pull x86 CFI fixes from Peter Zijlstra:
 "Fix kCFI/FineIBT weaknesses

  The primary bug Alyssa noticed was that with FineIBT enabled function
  prologues have a spurious ENDBR instruction:

    __cfi_foo:
	endbr64
	subl	$hash, %r10d
	jz	1f
	ud2
	nop
    1:
    foo:
	endbr64 <--- *sadface*

  This means that any indirect call that fails to target the __cfi
  symbol and instead targets (the regular old) foo+0, will succeed due
  to that second ENDBR.

  Fixing this led to the discovery of a single indirect call that was
  still doing this: ret_from_fork(). Since that's an assembly stub the
  compiler would not generate the proper kCFI indirect call magic and it
  would not get patched.

  Brian came up with the most comprehensive fix -- convert the thing to
  C with only a very thin asm wrapper. This ensures the kernel thread
  boostrap is a proper kCFI call.

  While discussing all this, Kees noted that kCFI hashes could/should be
  poisoned to seal all functions whose address is never taken, further
  limiting the valid kCFI targets -- much like we already do for IBT.

  So what was a 'simple' observation and fix cascaded into a bunch of
  inter-related CFI infrastructure fixes"

We used to insert the data commands following a pre-flush to the head
of the queue until commit 1e82fadf ("blk-mq: do not do head insertions
post-pre-flush commands").  Not doing this seems to cause hangs of
such commands on NFS workloads when exported from file systems with
SATA SSDs.  I have no idea why this would starve these workloads,
but doing a semantic revert of this patch (which looks quite different
due to various other changes) fixes the hangs.

The ida_alloc_range() function returns negative error codes on error.
On success it returns values in the min to max range (inclusive).  It
never returns more then INT_MAX even if "max" is higher.  It never
returns values in the 0 to (min - 1) range.

The bug is that "min" is an unsigned int so negative error codes will
be promoted to high positive values errors treated as success.

Fix to record 0-length data to data_loc in fetch_store_string*() if it fails
to get the string data.
Currently those expect that the data_loc is updated by store_trace_args() if
it returns the error code. However, that does not work correctly if the
argument is an array of strings. In that case, store_trace_args() only clears
the first entry of the array (which may have no error) and leaves other
entries. So it should be cleared by fetch_store_string*() itself.
Also, 'dyndata' and 'maxlen' in store_trace_args() should be updated
only if it is used (ret > 0 and argument is a dynamic data.)

Pull tracing fixes from Steven Rostedt:

 - Fix some missing-prototype warnings

 - Fix user events struct args (did not include size of struct)

   When creating a user event, the "struct" keyword is to denote that
   the size of the field will be passed in. But the parsing failed to
   handle this case.

 - Add selftest to struct sizes for user events

 - Fix sample code for direct trampolines.

   The sample code for direct trampolines attached to handle_mm_fault().
   But the prototype changed and the direct trampoline sample code was
   not updated. Direct trampolines needs to have the arguments correct
   otherwise it can fail or crash the system.

 - Remove unused ftrace_regs_caller_ret() prototype.

 - Quiet false positive of FORTIFY_SOURCE

   Due to backward compatibility, the structure used to save stack
   traces in the kernel had a fixed size of 8. This structure is
   exported to user space via the tracing format file. A change was made
   to allow more than 8 functions to be recorded, and user space now
   uses the size field to know how many functions are actually in the
   stack.

   But the structure still has size of 8 (even though it points into the
   ring buffer that has the required amount allocated to hold a full
   stack.

   This was fine until the fortifier noticed that the
   memcpy(&entry->caller, stack, size) was greater than the 8 functions
   and would complain at runtime about it.

   Hide this by using a pointer to the stack location on the ring buffer
   instead of using the address of the entry structure caller field.

 - Fix a deadloop in reading trace_pipe that was caused by a mismatch
   between ring_buffer_empty() returning false which then asked to read
   the data, but the read code uses rb_num_of_entries() that returned
   zero, and causing a infinite "retry".

 - Fix a warning caused by not using all pages allocated to store ftrace
   functions, where this can happen if the linker inserts a bunch of
   "NULL" entries, causing the accounting of how many pages needed to be
   off.

 - Fix histogram synthetic event crashing when the start event is
   removed and the end event is still using a variable from it

 - Fix memory leak in freeing iter->temp in tracing_release_pipe()

The iocost rely on rq start_time_ns and alloc_time_ns to tell saturation
state of the block device. Most of the time request is allocated after
rq_qos_throttle() and its alloc_time_ns or start_time_ns won't be affected.

But for plug batched allocation introduced by the commit 47c122e3
("block: pre-allocate requests if plug is started and is a batch"), we can
rq_qos_throttle() after the allocation of the request. This is what the
blk_mq_get_cached_request() does.

In this case, the cached request alloc_time_ns or start_time_ns is much
ahead if blocked in any qos ->throttle().

Fix it by setting alloc_time_ns and start_time_ns to now when the allocated
request is actually used.

An otherwise correct change to the atomic operations uncovered an
existing bug in the sparc __arch_xchg() function, which is calls
__xchg_called_with_bad_pointer() when its arguments are unknown at
compile time:

ERROR: modpost: "__xchg_called_with_bad_pointer" [lib/atomic64_test.ko] undefined!

This now happens because gcc determines that it's better to not inline the
function. Avoid this by just marking the function as __always_inline
to force the compiler to do the right thing here.

This reverts commit 2e9906f8.

It was turned out that commit 2e9906f8 ("tracing: Add "(fault)"
name injection to kernel probes") did not work correctly and probe
events still show just '(fault)' (instead of '"(fault)"'). Also,
current '(fault)' is more explicit that it faulted.

This also moves FAULT_STRING macro to trace.h so that synthetic
event can keep using it, and uses it in trace_probe.c too.

While duplicate IDs are still very harmful, including the potential to easily
see changing devices in /dev/disk/by-id, it turn out they are extremely
common for cheap end user NVMe devices.

Relax our check for them for so that it doesn't reject the probe on
single-ported PCIe devices, but prints a big warning instead.  In doubt
we'd still like to see quirk entries to disable the potential for
changing supposed stable device identifier links, but this will at least
allow users how have two (or more) of these devices to use them without
having to manually add a new PCI ID entry with the quirk through sysfs or
by patching the kernel.

ceph_frame_desc::fd_lens is an int array.  decode_preamble() thus
effectively casts u32 -> int but the checks for segment lengths are
written as if on unsigned values.  While reading in HELLO or one of the
AUTH frames (before authentication is completed), arithmetic in
head_onwire_len() can get duped by negative ctrl_len and produce
head_len which is less than CEPH_PREAMBLE_LEN but still positive.
This would lead to a buffer overrun in prepare_read_control() as the
preamble gets copied to the newly allocated buffer of size head_len.
