      Revert "kernel/reboot.c: convert simple_strtoul to kstrtoint" · 8b92c4ff
      由 Matteo Croce 提交于 
      Patch series "fix parsing of reboot= cmdline", v3.

The parsing of the reboot= cmdline has two major errors:

 - a missing bound check can crash the system on reboot

 - parsing of the cpu number only works if specified last

Fix both.

This patch (of 2):

This reverts commit 616feab7.

kstrtoint() and simple_strtoul() have a subtle difference which makes
them non interchangeable: if a non digit character is found amid the
parsing, the former will return an error, while the latter will just
stop parsing, e.g.  simple_strtoul("123xyx") = 123.

The kernel cmdline reboot= argument allows to specify the CPU used for
rebooting, with the syntax `s####` among the other flags, e.g.
"reboot=warm,s31,force", so if this flag is not the last given, it's
silently ignored as well as the subsequent ones.

      compiler.h: fix barrier_data() on clang · 3347acc6
      由 Arvind Sankar 提交于 
      Commit 815f0ddb ("include/linux/compiler*.h: make compiler-*.h
mutually exclusive") neglected to copy barrier_data() from
compiler-gcc.h into compiler-clang.h.

The definition in compiler-gcc.h was really to work around clang's more
aggressive optimization, so this broke barrier_data() on clang, and
consequently memzero_explicit() as well.

For example, this results in at least the memzero_explicit() call in
lib/crypto/sha256.c:sha256_transform() being optimized away by clang.

Fix this by moving the definition of barrier_data() into compiler.h.

Also move the gcc/clang definition of barrier() into compiler.h,
__memory_barrier() is icc-specific (and barrier() is already defined
using it in compiler-intel.h) and doesn't belong in compiler.h.

      When FOLL_PIN is passed to __get_user_pages() the page list must be put
back using unpin_user_pages() otherwise the page pin reference persists
in a corrupted state.

There are two places in the unwind of __gup_longterm_locked() that put
the pages back without checking.  Normally on error this function would
return the partial page list making this the caller's responsibility,
but in these two cases the caller is not allowed to see these pages at
all.

This pointing to the following code:

The panic occurred in slab_alloc_node() when checking for the page's node:

	object = c->freelist;
	page = c->page;
	if (unlikely(!object || !node_match(page, node))) {
		object = __slab_alloc(s, gfpflags, node, addr, c);
		stat(s, ALLOC_SLOWPATH);

The issue is that object is not NULL while page is NULL which is odd but
may happen if the cache flush happened after loading object but before
loading page.  Thus checking for the page pointer is required too.

The cache flush is done through an inter processor interrupt when a
piece of memory is off-lined.  That interrupt is triggered when a memory
hot-unplug operation is initiated and offline_pages() is calling the
slub's MEM_GOING_OFFLINE callback slab_mem_going_offline_callback()
which is calling flush_cpu_slab().  If that interrupt is caught between
the reading of c->freelist and the reading of c->page, this could lead
to such a situation.  That situation is expected and the later call to
this_cpu_cmpxchg_double() will detect the change to c->freelist and redo
the whole operation.

In commit 6159d0f5 ("mm/slub.c: page is always non-NULL in
node_match()") check on the page pointer has been removed assuming that
page is always valid when it is called.  It happens that this is not
true in that particular case, so check for page before calling
node_match() here.

      mm/compaction: stop isolation if too many pages are isolated and we have pages to migrate · d20bdd57
      由 Zi Yan 提交于 
      In isolate_migratepages_block, if we have too many isolated pages and
nr_migratepages is not zero, we should try to migrate what we have
without wasting time on isolating.

In theory it's possible that multiple parallel compactions will cause
too_many_isolated() to become true even if each has isolated less than
COMPACT_CLUSTER_MAX, and loop forever in the while loop.  Bailing
immediately prevents that.

      mm/compaction: count pages and stop correctly during page isolation · 38935861
      由 Zi Yan 提交于 
      In isolate_migratepages_block, when cc->alloc_contig is true, we are
able to isolate compound pages.  But nr_migratepages and nr_isolated did
not count compound pages correctly, causing us to isolate more pages
than we thought.

So count compound pages as the number of base pages they contain.
Otherwise, we might be trapped in too_many_isolated while loop, since
the actual isolated pages can go up to COMPACT_CLUSTER_MAX*512=16384,
where COMPACT_CLUSTER_MAX is 32, since we stop isolation after
cc->nr_migratepages reaches to COMPACT_CLUSTER_MAX.

In addition, after we fix the issue above, cc->nr_migratepages could
never be equal to COMPACT_CLUSTER_MAX if compound pages are isolated,
thus page isolation could not stop as we intended.  Change the isolation
stop condition to '>='.

The issue can be triggered as follows:

In a system with 16GB memory and an 8GB CMA region reserved by
hugetlb_cma, if we first allocate 10GB THPs and mlock them (so some THPs
are allocated in the CMA region and mlocked), reserving 6 1GB hugetlb
pages via /sys/kernel/mm/hugepages/hugepages-1048576kB/nr_hugepages will
get stuck (looping in too_many_isolated function) until we kill either
task.  With the patch applied, oom will kill the application with 10GB
THPs and let hugetlb page reservation finish.

      Pull pin control fixes from Linus Walleij:
 "A bunch of pin control fixes for the v5.10 kernel series.

  Nothing in particular to say about it, because they are all driver
  fixes.

  I'm happy that some AMD driver fixes are appearing, it's been an
  undermaintained driver, and laptops have suffered.

  Summary:

   - Two fixes to the Intel pin controller drivers: fixing pull
     resistance bias.

   - Fix some invalid SSI pins on the Ingenic pin controller.

   - Make sure the clock is enabled when requesting interrupts from the
     Rockchip GPIO controller.

   - Make sure IRQs are mapped when looking up the IRQ for a GPIO line
     on the Rockchip GPIO Write.

   - Two regmap initialization fixes for the MCP23s08.

   - Fix a GPI-only prefix function problem on the Aspeed pin
     controller.

   - Disable the debounce filter correctly on the AMD pin controller.

   - Correct the timer clock setting for the AMD debounce timer.

   - Make the Qualcomm pin controller more cautious around the handling
     of PDC-related GPIO interrupts.

   - Fix the interrupt map in the Qualcomm SM8250 pin controller"

 "Some GPIO fixes I've collected with the help of Bartosz.

  Nothing special about them: all are driver and kbuild fixes + some
  documentation fixes:

     userspace API documentation
