get_hash_bucket() and put_hash_bucket() acquire and release the same
spinlock, but this confuses static checkers such as sparse

  lib/dma-debug.c:268:13: warning: context imbalance in 'put_hash_bucket' - unexpected unlock

Add the appropriate acquire and release statements so that checkers can
properly track the lock state.

Remove the unused wrappers dax_fault() and dax_pmd_fault().  After this
removal, rename __dax_fault() and __dax_pmd_fault() to dax_fault() and
dax_pmd_fault() respectively, and update all callers.

The dax_fault() and dax_pmd_fault() wrappers were initially intended to
capture some filesystem independent functionality around page faults
(calling sb_start_pagefault() & sb_end_pagefault(), updating file mtime
and ctime).

However, the following commits:

   5726b27b ("ext2: Add locking for DAX faults")
   ea3d7209 ("ext4: fix races between page faults and hole punching")

added locking to the ext2 and ext4 filesystems after these common
operations but before __dax_fault() and __dax_pmd_fault() were called.
This means that these wrappers are no longer used, and are unlikely to
be used in the future.

XFS has had locking analogous to what was recently added to ext2 and
ext4 since DAX support was initially introduced by:

   6b698ede ("xfs: add DAX file operations support")

__GFP_REPEAT has a rather weak semantic but since it has been introduced
around 2.6.12 it has been ignored for low order allocations.

PGALLOC_GFP uses __GFP_REPEAT but none of the allocation which uses this
flag is for more than order-2.  This means that this flag has never been
actually useful here because it has always been used only for
PAGE_ALLOC_COSTLY requests.

Pull perf updates from Ingo Molnar:
 "With over 300 commits it's been a busy cycle - with most of the work
  concentrated on the tooling side (as it should).

  The main kernel side enhancements were:

   - Add per event callchain limit: Recently we introduced a sysctl to
     tune the max-stack for all events for which callchains were
     requested:

       $ sysctl kernel.perf_event_max_stack
       kernel.perf_event_max_stack = 127

     Now this patch introduces a way to configure this per event, i.e.
     this becomes possible:

       $ perf record -e sched:*/max-stack=2/ -e block:*/max-stack=10/ -a

     allowing finer tuning of how much buffer space callchains use.

     This uses an u16 from the reserved space at the end, leaving
     another u16 for future use.

     There has been interest in even finer tuning, namely to control the
     max stack for kernel and userspace callchains separately.  Further
     discussion is needed, we may for instance use the remaining u16 for
     that and when it is present, assume that the sample_max_stack
     introduced in this patch applies for the kernel, and the u16 left
     is used for limiting the userspace callchain (Arnaldo Carvalho de
     Melo)

   - Optimize AUX event (hardware assisted side-band event) delivery
     (Kan Liang)

   - Rework Intel family name macro usage (this is partially x86 arch
     work) (Dave Hansen)

   - Refine and fix Intel LBR support (David Carrillo-Cisneros)

   - Add support for Intel 'TopDown' events (Andi Kleen)

   - Intel uncore PMU driver fixes and enhancements (Kan Liang)

   - ... other misc changes.

  Here's an incomplete list of the tooling enhancements (but there's
  much more, see the shortlog and the git log for details):

   - Support cross unwinding, i.e.  collecting '--call-graph dwarf'
     perf.data files in one machine and then doing analysis in another
     machine of a different hardware architecture.  This enables, for
     instance, to do:

       $ perf record -a --call-graph dwarf

     on a x86-32 or aarch64 system and then do 'perf report' on it on a
     x86_64 workstation (He Kuang)

   - Allow reading from a backward ring buffer (one setup via
     sys_perf_event_open() with perf_event_attr.write_backward = 1)
     (Wang Nan)

   - Finish merging initial SDT (Statically Defined Traces) support, see
     cset comments for details about how it all works (Masami Hiramatsu)

   - Support attaching eBPF programs to tracepoints (Wang Nan)

   - Add demangling of symbols in programs written in the Rust language
     (David Tolnay)

   - Add support for tracepoints in the python binding, including an
     example, that sets up and parses sched:sched_switch events,
     tools/perf/python/tracepoint.py (Jiri Olsa)

   - Introduce --stdio-color to set up the color output mode selection
     in 'annotate' and 'report', allowing emit color escape sequences
     when redirecting the output of these tools (Arnaldo Carvalho de
     Melo)

   - Add 'callindent' option to 'perf script -F', to indent the Intel PT
     call stack, making this output more ftrace-like (Adrian Hunter,
     Andi Kleen)

   - Allow dumping the object files generated by llvm when processing
     eBPF scriptlet events (Wang Nan)

   - Add stackcollapse.py script to help generating flame graphs (Paolo
     Bonzini)

   - Add --ldlat option to 'perf mem' to specify load latency for loads
     event (e.g. cpu/mem-loads/ ) (Jiri Olsa)

   - Tooling support for Intel TopDown counters, recently added to the
     kernel (Andi Kleen)"

Pull gfs2 updates from Bob Peterson:
 "We've got ten patches this time, half of which are related to a
  plethora of nasty outcomes when inodes are transitioned from the
  unlinked state to the free state.  Small file systems are particularly
  vulnerable to these problems, and it can manifest as mainly hangs, but
  also file system corruption.  The patches have been tested for
  literally many weeks, with a very gruelling test, so I have a high
  level of confidence.

   - Andreas Gruenbacher wrote a series of five patches for various
     lockups during the transition of inodes from unlinked to free.

     The main patch is titled "Fix gfs2_lookup_by_inum lock inversion"
     and the other four are support and cleanup patches related to that.

   - Ben Marzinski contributed two patches with regard to a recreatable
     problem when gfs2 tries to write a page to a file that is being
     truncated, resulting in a BUG() in gfs2_remove_from_journal.

     Note that Ben had to export vfs function __block_write_full_page to
     get this to work properly.  It's been posted a long time and he
     talked to various VFS people about it, and nobody seemed to mind.

   - I contributed 3 patches:
       o The first one fixes a memory corruptor: a race in which one
         process can overwrite the gl_object pointer set by another
         process, causing kernel panic and other symptoms.
       o The second patch fixes another race that resulted in a
         false-positive BUG_ON.  This occurred when resource group
         reservations were freed by one process while another process
         was trying to grab a new reservation in the same resource
         group.
       o The third patch fixes a problem with doing journal replay when
         the journals are not all the same size"

Valdis Kletnieks bisected a boot failure back to this recent commit:

  360cb4d1 ("x86/mm/cpa: In populate_pgd(), don't set the PGD entry until it's populated")

I broke the case where a PUD table got allocated -- populate_pud()
would wander off a pgd_none entry and get lost.  I'm not sure how
this survived my testing.

Fix the original issue in a much simpler way.  The problem
was that, if we allocated a PUD table, failed to populate it, and
freed it, another CPU could potentially keep using the PGD entry we
installed (either by copying it via vmalloc_fault or by speculatively
caching it).  There's a straightforward fix: simply leave the
top-level entry in place if this happens.  This can't waste any
significant amount of memory -- there are at most 256 entries like
this systemwide and, as a practical matter, if we hit this failure
path repeatedly, we're likely to reuse the same page anyway.

For context, this is a reversion with this hunk added in:

	if (ret < 0) {
+		/*
+		 * Leave the PUD page in place in case some other CPU or thread
+		 * already found it, but remove any useless entries we just
+		 * added to it.
+		 */
-		unmap_pgd_range(cpa->pgd, addr,
+		unmap_pud_range(pgd_entry, addr,
			        addr + (cpa->numpages << PAGE_SHIFT));
		return ret;
	}

This effectively open-codes what the now-deleted unmap_pgd_range()
function used to do except that unmap_pgd_range() used to try to
free the page as well.
