vmx_hv_remote_flush_tlb()
I'm observing random crashes in multi-vCPU L2 guests running on KVM on
Hyper-V. I bisected the issue to the commit 877ad952be3d ("KVM: vmx: Add
tlb_remote_flush callback support"). Hyper-V TLFS states:
"AddressSpace specifies an address space ID (an EPT PML4 table pointer)"
So apparently, Hyper-V doesn't expect us to pass naked EPTP, only PML4
pointer should be used. Strip off EPT configuration information before
calling into vmx_hv_remote_flush_tlb().

ubifs_assert() is not WARN_ON(), so we have to invert
the checks.
Randy faced this warning with UBIFS being a module, since
most users use UBIFS as builtin because UBIFS is the rootfs
nobody noticed so far. :-(

Inside set_pmd_migration_entry() we are holding page table locks and thus
we can not sleep so we can not call invalidate_range_start/end()
So remove call to mmu_notifier_invalidate_range_start/end() because they
are call inside the function calling set_pmd_migration_entry() (see
try_to_unmap_one()).

Daniel Micay reports that attempting to use MAP_FIXED_NOREPLACE in an
application causes that application to randomly crash. The existing check
for handling MAP_FIXED_NOREPLACE looks up the first VMA that either
overlaps or follows the requested region, and then bails out if that VMA
overlaps *the start* of the requested region. It does not bail out if the
VMA only overlaps another part of the requested region.
Fix it by checking that the found VMA only starts at or after the end of
the requested region, in which case there is no overlap.
Test case:
user@debian:~$ cat mmap_fixed_simple.c
#include <sys/mman.h>
#include <errno.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>

Fix a leak of afs_server structs. The routine that installs them in the
various lookup lists and trees gets a ref on leaving the function, whether
it added the server or a server already exists. It shouldn't increment
the refcount if it added the server.
The effect of this that "rmmod kafs" will hang waiting for the leaked
server to become unused.

It turns out that the fix in commit 6636c3cc56 is bad; the assertion
that the iomap code no longer creates buffer heads is incorrect for
filesystems that set the IOMAP_F_BUFFER_HEAD flag.
Instead, what's happening is that gfs2_iomap_begin_write treats all
files that have the jdata flag set as journaled files, which is
incorrect as long as those files are inline ("stuffed"). We're handling
stuffed files directly via the page cache, which is why we ended up with
pages without buffer heads in gfs2_page_add_databufs.
Fix this by handling stuffed journaled files correctly in
gfs2_iomap_begin_write.
This reverts commit 6636c3cc5690c11631e6366cf9a28fb99c8b25bb.

It doesn't make sense for a perf event to be configured as a CHAIN event

We describe ranges of 'reserved' memory to userspace via /proc/iomem.
Commit 50d7ba36b916 ("arm64: export memblock_reserve()d regions via
/proc/iomem") updated the logic to export regions that were reserved
because their contents should be preserved. This allowed kexec-tools
to tell the difference between 'reserved' memory that must be
preserved and not overwritten, (e.g. the ACPI tables), and 'nomap'
memory that must not be touched without knowing the memory-attributes
(e.g. RAS CPER regions).
The above commit wrongly assumed that memblock_reserve() would not
be used to reserve regions that aren't memory. It turns out this is
exactly what early_init_dt_reserve_memory_arch() will do if it finds
a DT reserved-memory that was also carved out of the memory node, which
results in a WARN_ON_ONCE() and the region being reserved instead of
ignored. The ramoops description on hikey and dragonboard-410c both do
this, so we can't simply write this configuration off as "buggy firmware".
Avoid this issue by rewriting reserve_memblock_reserved_regions() so
that only the portions of reserved regions which overlap with mapped
memory are actually reserved.

Access to the list of cells by /proc/net/afs/cells has a couple of
problems:
(1) It should be checking against SEQ_START_TOKEN for the keying the
header line.
(2) It's only holding the RCU read lock, so it can't just walk over the
list without following the proper RCU methods.
Fix these by using an hlist instead of an ordinary list and using the
appropriate accessor functions to follow it with RCU.
Since the code that adds a cell to the list must also necessarily change,
sort the list on insertion whilst we're at it.
