Pull timer migration updates from Thomas Gleixner:
 "Fixes and minor updates for the timer migration code:

   - Stop testing the group->parent pointer as it is not guaranteed to
     be stable over a chain of operations by design.

     This includes a warning which would be nice to have but it produces
     false positives due to the racy nature of the check.

   - Plug a race between CPUs going in and out of idle and a CPU hotplug
     operation. The latter can create and connect a new hierarchy level
     which is missed in the concurrent updates of CPUs which go into
     idle. As a result the events of such a CPU might not be processed
     and timers go stale.

     Cure it by splitting the hotplug operation into a prepare and
     online callback. The prepare callback is guaranteed to run on an
     online and therefore active CPU. This CPU updates the hierarchy and
     being online ensures that there is always at least one migrator
     active which handles the modified hierarchy correctly when going
     idle. The online callback which runs on the incoming CPU then just
     marks the CPU active and brings it into operation.

   - Improve tracing and polish the code further so it is more obvious

In a commit 1d717123 ("ALSA: firewire-lib: Avoid
-Wflex-array-member-not-at-end warning"), DEFINE_FLEX() macro was used to
handle variable length of array for header field in struct fw_iso_packet
structure. The usage of macro has a side effect that the designated
initializer assigns the count of array to the given field. Therefore
CIP_HEADER_QUADLETS (=2) is assigned to struct fw_iso_packet.header,
while the original designated initializer assigns zero to all fields.

With CIP_NO_HEADER flag, the change causes invalid length of header in
isochronous packet for 1394 OHCI IT context. This bug affects all of
devices supported by ALSA fireface driver; RME Fireface 400, 800, UCX, UFX,
and 802.

This commit fixes the bug by replacing it with the alternative version of
macro which corresponds no initializer.

The minmax infrastructure is overkill for simple constants, and can
cause huge expansions because those simple constants are then used by
other things.

For example, 'pageblock_order' is a core VM constant, but because it was
implemented using 'min_t()' and all the type-checking that involves, it
actually expanded to something like 2.5kB of preprocessor noise.

And when that simple constant was then used inside other expansions:

  #define pageblock_nr_pages      (1UL << pageblock_order)
  #define pageblock_start_pfn(pfn)  ALIGN_DOWN((pfn), pageblock_nr_pages)

and we then use that inside a 'max()' macro:

	case ISOLATE_SUCCESS:
		update_cached = false;
		last_migrated_pfn = max(cc->zone->zone_start_pfn,
			pageblock_start_pfn(cc->migrate_pfn - 1));

the end result was that one statement expanding to 253kB in size.

There are probably other cases of this, but this one case certainly
stood out.

I've added 'MIN_T()' and 'MAX_T()' macros for this kind of "core simple
constant with specific type" use.  These macros skip the type checking,
and as such need to be very sparingly used only for obvious cases that
have active issues like this.

We have some very fancy min/max macros that have tons of sanity checking
to warn about mixed signedness etc.

This is all things that a sane compiler should warn about, but there are
no sane compiler interfaces for this, and '-Wsign-compare' is broken [1]
and not useful.

So then we compensate (some would say over-compensate) by doing the
checks manually with some truly horrid macro games.

And no, we can't just use __builtin_types_compatible_p(), because the
whole question of "does it make sense to compare these two values" is a
lot more complicated than that.

For example, it makes a ton of sense to compare unsigned values with
simple constants like "5", even if that is indeed a signed type.  So we
have these very strange macros to try to make sensible type checking
decisions on the arguments to 'min()' and 'max()'.

But that can cause enormous code expansion if the min()/max() macros are
used with complicated expressions, and particularly if you nest these
things so that you get the first big expansion then expanded again.

The xen setup.c file ended up ballooning to over 50MB of preprocessed
noise that takes 15s to compile (obviously depending on the build host),
largely due to one single line.

So let's split that one single line to just be simpler.  I think it ends
up being more legible to humans too at the same time.  Now that single
file compiles in under a second.

Syzbot reported that a buffer state inconsistency was detected in
nilfs_btnode_create_block(), triggering a kernel bug.

It is not appropriate to treat this inconsistency as a bug; it can occur
if the argument block address (the buffer index of the newly created
block) is a virtual block number and has been reallocated due to
corruption of the bitmap used to manage its allocation state.

So, modify nilfs_btnode_create_block() and its callers to treat it as a
possible filesystem error, rather than triggering a kernel bug.

It's expected that no page should be left in pcp_list after calling
zone_pcp_disable() in offline_pages().  Previously, it's observed that
offline_pages() gets stuck [1] due to some pages remaining in pcp_list.

Cause:
There is a race condition between drain_pages_zone() and __rmqueue_pcplist()
involving the pcp->count variable. See below scenario:

         CPU0                              CPU1
    ----------------                    ---------------
                                      spin_lock(&pcp->lock);
                                      __rmqueue_pcplist() {
zone_pcp_disable() {
                                        /* list is empty */
                                        if (list_empty(list)) {
                                          /* add pages to pcp_list */
                                          alloced = rmqueue_bulk()
  mutex_lock(&pcp_batch_high_lock)
  ...
  __drain_all_pages() {
    drain_pages_zone() {
      /* read pcp->count, it's 0 here */
      count = READ_ONCE(pcp->count)
      /* 0 means nothing to drain */
                                          /* update pcp->count */
                                          pcp->count += alloced << order;
      ...
                                      ...
                                      spin_unlock(&pcp->lock);

In this case, after calling zone_pcp_disable() though, there are still some
pages in pcp_list. And these pages in pcp_list are neither movable nor
isolated, offline_pages() gets stuck as a result.

Solution:
Expand the scope of the pcp->lock to also protect pcp->count in
drain_pages_zone(), to ensure no pages are left in the pcp list after
zone_pcp_disable()

Oliver Sand reported a performance regression caused by commit
98c9daf5 ("mm: memcg: guard memcg1-specific members of struct
mem_cgroup_per_node"), which puts some fields of the mem_cgroup_per_node
structure under the CONFIG_MEMCG_V1 config option.  Apparently it causes a
false cache sharing between lruvec and lru_zone_size members of the
structure.  Fix it by adding an explicit padding after the lruvec member.

Even though the padding is not required with CONFIG_MEMCG_V1 set, it seems
like the introduced memory overhead is not significant enough to warrant
another divergence in the mem_cgroup_per_node layout, so the padding is
added unconditionally.

The decompression code parses a huffman tree and counts the number of
symbols for a given bit length.  In rare cases, there may be >= 256
symbols with a given bit length, causing the unsigned char to overflow. 
This causes a decompression failure later when the code tries and fails to
find the bit length for a given symbol.

Since the maximum number of symbols is 258, use unsigned short instead.

xarray can't support arbitrary page cache size.  the largest and supported
page cache size is defined as MAX_PAGECACHE_ORDER by commit 099d9064
("mm/filemap: make MAX_PAGECACHE_ORDER acceptable to xarray").  However,
it's possible to have 512MB page cache in the huge memory's collapsing
path on ARM64 system whose base page size is 64KB.  512MB page cache is
breaking the limitation and a warning is raised when the xarray entry is
split as shown in the following example.

[root@dhcp-10-26-1-207 ~]# cat /proc/1/smaps | grep KernelPageSize

Fix it by correcting the supported page cache orders, different sets for
DAX and other files.  With it corrected, 512MB page cache becomes
disallowed on all non-DAX files on ARM64 system where the base page size
is 64KB.  After this patch is applied, the test program fails with error
-EINVAL returned from __thp_vma_allowable_orders() and the madvise()
system call to collapse the page caches.

Commit 3bd786f7 ("mm: convert do_set_pte() to set_pte_range()")
replaced do_set_pte() with set_pte_range() and that introduced a
regression in the following faulting path of non-anonymous vmas which
caused the PTE for the faulting address to be marked as old instead of
young.

handle_pte_fault()
  do_pte_missing()
    do_fault()
      do_read_fault() || do_cow_fault() || do_shared_fault()
        finish_fault()
          set_pte_range()

The polarity of prefault calculation is incorrect.  This leads to prefault
being incorrectly set for the faulting address.  The following check will
incorrectly mark the PTE old rather than young.  On some architectures
this will cause a double fault to mark it young when the access is
retried.

    if (prefault && arch_wants_old_prefaulted_pte())
        entry = pte_mkold(entry);

On a subsequent fault on the same address, the faulting path will see a
non NULL vmf->pte and instead of reaching the do_pte_missing() path, PTE
will then be correctly marked young in handle_pte_fault() itself.

Due to this bug, performance degradation in the fault handling path will
be observed due to unnecessary double faulting.

On arm64 we build compressed images, but "make install" by default will
install the old non-compressed one.  To actually get the compressed
image install, you need to use "make zinstall", which is not the usual
way to install a kernel.

Which may not sound like much of an issue, but when you deal with
multiple architectures (and years of your fingers knowing the regular
"make install" incantation), this inconsistency is pretty annoying.

But as Will Deacon says:
 "Sadly, bootloaders being as top quality as you might expect, I don't
  think we're in a position to rely on decompressor support across the
  board. Our Image.gz is literally just that -- we don't have a built-in
  decompressor (nor do I think we want to rush into that again after the
  fun we had on arm32) and the recent EFI zboot support solves that
  problem for platforms using EFI.

  Changing the default 'install' target terrifies me. There are bound to
  be folks with embedded boards who've scripted this and we could really
  ruin their day if we quietly give them a compressed kernel that their
  bootloader doesn't know how to handle :/"

So make this conditional on a new "COMPRESSED_INSTALL" option.
