4437992be7 ext4: remove lazytime/nolazytime mount options handled by MS_LAZYTIME
The lazytime and nolazytime mount options were added temporarily back in
2015 with commit a26f49926d ("ext4: add optimization for the lazytime
mount option"). It think it has been enough time for the util-linux with
lazytime support to get widely used. Remove the mount options.

4c24672877 ext4: don't fail remount if journalling mode didn't change
Switching to the new mount api introduced inconsistency in how the
journalling mode mount option (data=) is handled during a remount.

Ext4 always prevented changing the journalling mode during the remount,
however the new code always fails the remount when the journalling mode
is specified, even if it remains unchanged. Fix it.

669a064625 block: drop needless assignment in set_task_ioprio()
Commit 5fc11eebb4 ("block: open code create_task_io_context in
set_task_ioprio") introduces a needless assignment
'ioc = task->io_context', as the local variable ioc is not further
used before returning.

Even after the further fix, commit a957b61254 ("block: fix error in
handling dead task for ioprio setting"), the assignment still remains
needless.

Drop this needless assignment in set_task_ioprio().

This code smell was identified with 'make clang-analyzer'.

contains the number of dummy cycles. This is very fortunate since the
enable path changes the value of this register. Reset the value to its
default when disabling Octal DTR mode. This way, both changes to the
flash state made when enabling can be reverted in one single
transaction.

63017068a6 mtd: spi-nor: spansion: write 2 bytes when disabling Octal DTR mode
The Octal DTR configuration is stored in the CFR5V register. This
register is 1 byte wide. But 1 byte long transactions are not allowed in
8D-8D-8D mode. Since the next byte address does not contain any
register, it is safe to write any value to it. Write a 0 to it.

0d051a4982 mtd: spi-nor: core: use 2 data bytes for template ops
The template ops used in spi_nor_spimem_check_pp() and
spi_nor_spimem_check_readop() currently set the data phase to 1 byte
long. This is problematic for 8D-8D-8D protocol where odd length data
phase is invalid since one cycle transfers 2 bytes and odd number of
bytes would mean half a cycle is left over. This could result in a
controller rejecting the op as "not supported" even though it actually
supports the protocol.

Change the data length to 2 bytes in these templates. One might argue
that this should only be done for 8D-8D-8D operations but when talking
about these templates, there is no functional difference between one and
two bytes, even in STR modes.

798c5daf3c drm/i915/fbc: Remember to update FBC state even when not reallocating CFB
We mustn't forget to update our FBC state even if we don't have
to reallocate the CFB. Otherwise we won't refresh our notion
of what eg. the new fence or the new override CFB stride
should be. Using the wrong CFB stride in particular can cause
underruns and could even corrupt other stuff in stolen.

Boot fails with GCC latent entropy plugin enabled.

This is due to early boot functions trying to access 'latent_entropy'

destination yet.

As there is no way to tell GCC to use PTRRELOC() to access it,
disable latent entropy plugin in early_32.o and feature-fixups.o and
code-patching.o

309a0a6018 powerpc/code-patching: Replace patch_instruction() by ppc_inst_write() in selftests
The purpose of selftests is to check that instructions are
properly formed. Not to check that they properly run.

For that test it uses normal memory, not special test
memory.

In preparation of a future patch enforcing patch_instruction()
to be used only on valid text areas, implement a ppc_inst_write()
instruction which is the complement of ppc_inst_read(). This
new function writes the formated instruction in valid kernel
memory and doesn't bother about icache.

a3483c3dd1 powerpc/code-patching: Fix unmap_patch_area() error handling
pXd_offset() doesn't return NULL. When the base is NULL, it
still adds the offset.

Use pXd_none() to check validity instead. It also improves
performance by folding out none existing levels as pXd_none()
always returns 0 in that case.

Such an error is unexpected, use WARN_ON() so that the caller
doesn't have to worry about it, and drop the returned value.

And now that unmap_patch_area() doesn't return error, we can
take into account the error returned by __patch_instruction().

While at it, remove the 'inline' property which is useless.
