and make no difference.

Quoting Aditya Pakki:
 "I was the author of the patch and it was the cause of the giant UMN
  revert.

  The patch is garbage and I was unaware of the steps involved in
  retracting it. I *believed* the maintainers would pull it, given it
  was already under Greg's list. The patch does not introduce any bugs
  but is pointless and is stupid. I accept my incompetence and for not

No problem on 64-bit, or without huge pages, but xfstests generic/285
and other SEEK_HOLE/SEEK_DATA tests have regressed on huge tmpfs, and on
32-bit architectures, with the new mapping_seek_hole_data().  Several
different bugs turned out to need fixing.

u64 cast to stop losing bits when converting unsigned long to loff_t
(and let's use shifts throughout, rather than mixed with * and /).

Use round_up() when advancing pos, to stop assuming that pos was already
THP-aligned when advancing it by THP-size.  (This use of round_up()
assumes that any THP has THP-aligned index: true at present and true
going forward, but could be recoded to avoid the assumption.)

Use xas_set() when iterating away from a THP, so that xa_index stays in
synch with start, instead of drifting away to return bogus offset.

Check start against end to avoid wrapping 32-bit xa_index to 0 (and to
handle these additional cases, seek_data or not, it's easier to break
the loop than goto: so rearrange exit from the function).

[hughd@google.com: remove unneeded u64 casts, per Matthew]

Pull tpm fix from James Bottomley:
 "This is an urgent regression fix for a tpm patch set that went in this
  merge window. It looks like a rebase before the original pull request
  lost a tpm_try_get_ops() so we have a lock imbalance in our code which
  is causing oopses. The original patch was correct on the mailing list.

  I'm sending this in agreement with Mimi (as joint maintainers of
  trusted keys) because Jarkko is off communing with the Reindeer or
  whatever it is Finns do when on holiday"

  KEYS: trusted: Fix TPM reservation for seal/unseal

The only stepping of Broadwell Xeon parts is stepping 1. Fix the
relevant isolation_ucodes[] entry, which previously enumerated
stepping 2.

Although the original commit was characterized as an optimization, it
is also a workaround for a correctness issue.

If a PMI arrives between kvm's call to perf_guest_get_msrs() and the
subsequent VM-entry, a stale value for the IA32_PEBS_ENABLE MSR may be
restored at the next VM-exit. This is because, unbeknownst to kvm, PMI
throttling may clear bits in the IA32_PEBS_ENABLE MSR. CPUs with "PEBS
isolation" don't suffer from this issue, because perf_guest_get_msrs()
doesn't report the IA32_PEBS_ENABLE value.

Commit 941432d0 ("arm64: dts: allwinner: Drop non-removable from
SoPine/LTS SD card") enabled the card detect GPIO for the SOPine module,
along the way with the Pine64-LTS, which share the same base .dtsi.

This was based on the observation that the Pine64-LTS has as "push-push"
SD card socket, and that the schematic mentions the card detect GPIO.

After having received two reports about failing SD card access with that
patch, some more research and polls on that subject revealed that there
are at least two different versions of the Pine64-LTS out there:
- On some boards (including mine) the card detect pin is "stuck" at
  high, regardless of an microSD card being inserted or not.
- On other boards the card-detect is working, but is active-high, by
  virtue of an explicit inverter circuit, as shown in the schematic.

To cover all versions of the board out there, and don't take any chances,
let's revert the introduction of the active-low CD GPIO, but let's use
the broken-cd property for the Pine64-LTS this time. That should avoid
regressions and should work for everyone, even allowing SD card changes
now.
The SOPine card detect has proven to be working, so let's keep that
GPIO in place.

CONFIG_CRYPTO_SHA256 denotes the generic C implementation of the SHA-256
shash algorithm, which is selected as the default crypto shash provider
for fsverity. However, fsverity has no strict link time dependency, and
the same shash could be exposed by an optimized implementation, and arm64
has a number of those (scalar, NEON-based and one based on special crypto
instructions). In such cases, it makes little sense to require that the
generic C implementation is incorporated as well, given that it will never
be called.

To address this, relax the 'select' clause to 'imply' so that the generic
driver can be omitted from the build if desired.

Even if FS encryption has strict functional dependencies on various
crypto algorithms and chaining modes. those dependencies could potentially
be satisified by other implementations than the generic ones, and no link
time dependency exists on the 'depends on' claused defined by
CONFIG_FS_ENCRYPTION_ALGS.

So let's relax these clauses to 'imply', so that the default behavior
is still to pull in those generic algorithms, but in a way that permits
them to be disabled again in Kconfig.
