Function _rtl8821ae_mrate_idx_to_arfr_id is functionally identical to
the generic version rtl_mrate_idx_to_arfr_id, so remove
_rtl8821ae_mrate_idx_to_arfr_id and use the generic one instead.
This also fixes a missing break statement found by CoverityScan in
_rtl8821ae_mrate_idx_to_arfr_id, namely: CID#1167237 ("Missing break
in switch")
Thanks to Joe Perches for spotting this when I submitted an earlier patch.

The rs_rate_from_ucode_rate() function may return -EINVAL if the rate
is invalid, but none of the callsites check for the error, potentially
making us access arrays with index IWL_RATE_INVALID, which is larger
than the arrays, causing an out-of-bounds access. This will trigger
KASAN warnings, such as the one reported in the bugzilla issue
mentioned below.

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>

Once upon a time a bunch of serial drivers used to provide that;
today it's only amiserial and it's FUBAR - the structure being
copied to userland includes kernel pointers, fields with
config-dependent size, etc. No userland code using it could
possibly survive - e.g. enabling lockdep definitely changes the
layout. Besides, it's a massive infoleak.
Kill it. If somebody needs that data for debugging purposes, they
can bloody well expose it saner ways. Assuming anyone does debugging
of amiserial in the first place, that is.

First of all, make it return int. Returning long when native method
had never allowed that is ridiculous and inconvenient.
More importantly, change the caller; if ldisc ->compat_ioctl() is NULL
or returns -ENOIOCTLCMD, tty_compat_ioctl() will try to feed cmd and
compat_ptr(arg) to ldisc's native ->ioctl().
That simplifies ->compat_ioctl() instances quite a bit - they only
need to deal with ioctls that are neither generic tty ones (those
would get shunted off to tty_ioctl()) nor simple compat pointer ones.
Note that something like TCFLSH won't reach ->compat_ioctl(),
even if ldisc ->ioctl() does handle it - it will be recognized
earlier and passed to tty_ioctl() (and ultimately - ldisc ->ioctl()).
For many ldiscs it means that NULL ->compat_ioctl() does the
right thing. Those where it won't serve (see e.g. n_r3964.c) are
also easily dealt with - we need to handle the numeric-argument
ioctls (calling the native instance) and, if such would exist,
the ioctls that need layout conversion, etc.
All in-tree ldiscs dealt with.
