The patch description is a bit off.
TPM2_ALG_ERROR is defined as zero. Since tpm_chip_alloc() calls
kzalloc to allocate the structure, there is no

Add a simple proc-based kill interface. To use /proc/pid/kill, just
write the signal number in base-10 ASCII to the kill file of the
process to be killed: for example, 'echo 9 > /proc/$$/kill'.
Semantically, /proc/pid/kill works like kill(2), except that the
process ID comes from the proc
Use the gpiod interface instead of the deprecated old non-descriptor
interface.

An external fragmentation causing events as already been described. A
serious external fragmentation causing event is described as one that steals
a contiguous range of pages of an order lower than fragment_stall_order

An external fragmentation event was previously described as
When the page allocator fragments memory, it records the event using
the mm_page_alloc_extfrag event. If the fallback_order is smaller
than a pageblock order (order-9 on 64-bit x86) then it's considered
an event that will
Despite the earlier patches, external fragmentation events are still
inevitable as not all callers can stall or are appropriate to stall
(e.g. unmovable allocations that kswapd reclaim will not necessarily
help). In the event there is a mixed pageblock, it's desirable to move all
movable pages

The page allocator zone lists are iterated based on the watermarks
of each zone which does not take anti-fragmentation into account. On
x86, node 0 may have multiple zones while other nodes have one zone. A
consequence is that tasks running on node 0 may fragment ZONE_NORMAL even
though ZONE_DMA32

Greetings,
version #3 of the fix for the pgtable_bytes mis-accounting problem
on s390. Three times is a charm..
Changes v2 -> v3:
- Add a fourth patch to redefine __PAGETABLE_PxD_FOLDED as non-empty
- Move mm_pxd_folded() to include/asm-generic/pgtable.h and use
__is_defined() again with

Add three architecture overrideable functions to test if the
p4d, pud, or pmd layer of a page table is folded or not.
