Workaround problem with Samba responses to SMB3.1.1
null user (guest) mounts. The server doesn't set the
expected flag in the session setup response so we have
to do a similar check to what is done in smb3_validate_negotiate
where we also check if the user is a null user (but not sec=krb5
since username might not be passed in on mount for Kerberos case).
Note that the commit below tightened the conditions and forced signing
for the SMB2-TreeConnect commands as per MS-SMB2.
However, this should only apply to normal user sessions and not for
cases where there is no user (even if server forgets to set the flag
in the response) since we don't have anything useful to sign with.
This is especially important now that the more secure SMB3.1.1 protocol
is in the default dialect list.
An earlier patch ("cifs: allow guest mounts to work for smb3.11") fixed
the guest mounts to Windows.
Fixes: 6188f28bf6 ("Tree connect for SMB3.1.1 must be signed for non-encrypted shares")

Fix Guest/Anonymous sessions so that they work with SMB 3.11.
The commit noted below tightened the conditions and forced signing for
the SMB2-TreeConnect commands as per MS-SMB2.
However, this should only apply to normal user sessions and not for
Guest/Anonumous sessions.
Fixes: 6188f28bf6 ("Tree connect for SMB3.1.1 must be signed for non-encrypted shares")

It was mapped to EIO which can be confusing when user space
queries for an object GUID for an object for which the server
file system doesn't support (or hasn't saved one).
As Amir Goldstein suggested this is similar to ENOATTR
(equivalently ENODATA in Linux errno definitions) so
changing NT STATUS code mapping for OBJECTID_NOT_FOUND
to ENODATA.

dedupe_file_range operations is combiled into remap_file_range.
But it's always skipped for dedupe operations in function
cifs_remap_file_range.
Example to test:
Before this patch:
# dd if=/dev/zero of=cifs/file bs=1M count=1
# xfs_io -c "dedupe cifs/file 4k 64k 4k" cifs/file
XFS_IOC_FILE_EXTENT_SAME: Invalid argument
After this patch:
# dd if=/dev/zero of=cifs/file bs=1M count=1
# xfs_io -c "dedupe cifs/file 4k 64k 4k" cifs/file
XFS_IOC_FILE_EXTENT_SAME: Operation not supported
Influence for xfstests:
generic/091
generic/112
generic/127
generic/263
These tests report this error "do_copy_range:: Invalid
argument" instead of "FIDEDUPERANGE: Invalid argument".
Because there are still two bugs cause these test failed.

One fix for a boot failure on 32-bit, introduced during the merge window.
A fix for our handling of CLOCK_MONOTONIC in the 64-bit VDSO. Changing the wall
clock across the Y2038 boundary could cause CLOCK_MONOTONIC to jump forward and
backward.
Our spectre_v2 reporting was a bit confusing due to a bug I introduced. On some
systems it was reporting that the count cache was disabled and also that we were
flushing the count cache on context switch. Only the former is true, and given
that the count cache is disabled it doesn't make any sense to flush it. No one
reported it, so presumably the presence of any mitigation is all people check
for.
Finally a small build fix for zsmalloc on 32-bit.

If a 32 bit allocation request is too big to possibly succeed, it
early exits with a failure and then should never update max32_alloc_

the slow path failed while walking the tree. Without the fix the
allocation may enter the slow path again even if there was a failure
before of a request with the same or a smaller size.

Objtool uses over 512k of stack, thanks to the hash table embedded in
the objtool_file struct. This causes an unnecessarily large stack
allocation and breaks users with low stack limits.
Move the struct off the stack.

R-Car Gen2 has two different SDHI incarnations in the same chip. The
older one does not support the recently introduced 32 bit register
access to the block count register. Make sure we use this feature only
after the first known version.

Setting max_blk_count to 1 here was causing the mmc block layer
to always use the MMC_READ_SINGLE_BLOCK command here, which the
driver does not DMA-accelerate.
Drop the max_blk_ settings here. The mmc host defaults suffice,
along with the max_segs and max_seg_size settings, which I have
now documented in more detail.
Now each MMC command reads 4 512-byte blocks, using DMA instead of
PIO. On my SD card, this increases read performance (measured with dd)
from 167kb/sec to 4.6mb/sec.

After commit 6d5cd068ee ("mmc: sdhci: use WP GPIO in
sdhci_check_ro()") and commit 39ee32ce48 ("mmc: sdhci-omap: drop
->get_ro() implementation"), sdhci-omap relied on SDHCI_PRESENT_STATE
to check if the card is read-only, if wp-gpios is not populated
in device tree. However SDHCI_PRESENT_STATE in sdhci-omap does not have
correct read-only state.
sdhci-omap can be used by platforms with both micro SD slot and standard
SD slot with physical write protect pin (using GPIO). Set caps2 to
MMC_CAP2_NO_WRITE_PROTECT based on if wp-gpios property is populated or
not.
This fix is required since existing device-tree node doesn't have
"disable-wp" property and to preserve old-dt compatibility.

When I updated the spectre_v2 reporting to handle software count cache
flush I got the logic wrong when there's no software count cache
enabled at all.
The result is that on systems with the software count cache flush
disabled we print:
Mitigation: Indirect branch cache disabled, Software count cache flush
Which correctly indicates that the count cache is disabled, but
incorrectly says the software count cache flush is enabled.
The root of the problem is that we are trying to handle all
combinations of options. But we know now that we only expect to see
the software count cache flush enabled if the other options are false.
So split the two cases, which simplifies the logic and fixes the bug.
We were also missing a space before "(hardware accelerated)".
The result is we see one of:
Mitigation: Indirect branch serialisation (kernel only)
Mitigation: Indirect branch cache disabled
Mitigation: Software count cache flush
Mitigation: Software count cache flush (hardware accelerated)
