This reverts commit 9b9f9296a7b73fbafe0a0a6f2494eaadd97f9f73 as
all in-kernel implementations of GCM have been converted to the
new AEAD interface, meaning that they should now pass the updated
rfc4543 test.

This patch converts the caam GCM implementations to the new AEAD
interface. This is compile-tested only.
Note that all IV generation for GCM algorithms have been removed.
The reason is that the current generation uses purely random IVs
which is not appropriate for counter-based algorithms where we
first and foremost require uniqueness.
Of course there is no reason why you couldn't implement seqiv or
seqniv within caam since all they do is xor the sequence number
with a salt, but since I can't test this on actual hardware I'll
leave it alone for now.

Currently dma_map_sg_chained does not handle errors from the
underlying dma_map_sg calls. This patch adds rollback in case
of an error by simply calling dma_unmap_sg_chained for the ones
that we've already mapped.
All current callers ignore the return value so this should have
no impact on them.

This patch converts generic gcm and its associated transforms to
the new AEAD interface. The biggest reward is in code reduction
for rfc4543 where it used to do IV stitching which is no longer
needed as the IV is already part of the AD on input.
Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
Because the old rfc4543 implementation always injected an IV into
the AD, while the new one does not, we have to disable the test
while it is converted over to the new AEAD interface.

Fix perf probe to return an error if no probe is added due to the given
probe point being on the blacklist.
To fix this problem, this moves the blacklist checking to right after
finding symbols/probe-points and marks them as skipped.
If all the symbols are skipped, "perf probe" returns an error as it
fails to find the corresponding probe address.
E.g. currently if a blacklisted probe is given:
# perf probe do_trap && echo 'succeed'
Added new event:
Warning: Skipped probing on blacklisted function: sync_regs
succeed
No! It must fail! With this patch, it correctly fails:
# perf probe do_trap && echo 'succeed'
do_trap is blacklisted function, skip it.

The Exynos interrupt combiner IP loses its state when the SoC enters
into a low power state during a Suspend-to-RAM. This means that if a
IRQ is used as a source, the interrupts for the devices are disabled
when the system is resumed from a sleep state so are not triggered.
Save the interrupt enable set register for each combiner group and
restore it after resume to make sure that the interrupts are enabled.

Now pcf857x_irq() IRQ's dispatcher will try to run nested
IRQ handlers for each GPIO pin which state has changed.
Such IRQs are, actually, spurious and nested IRQ handlers
have to be called only for IRQs wich were enabled by users.
This is not critical issue - just /proc/interrupts
will display counters for unused IRQS:
399: 4 0 pcf857x 0 Edge
428: 1 0 pcf857x 13 Edge
430: 1 0 pcf857x 15 Edge

The current handler of MMC_BLK_CMD_ERR in mmc_blk_issue_rw_rq function
may cause new coming request permanent missing when the ongoing
request (previoulsy started) complete end.
The problem scenario is as follows:
(1) Request A is ongoing;
(2) Request B arrived, and finally mmc_blk_issue_rw_rq() is called;
(3) Request A encounters the MMC_BLK_CMD_ERR error;
(4) In the error handling of MMC_BLK_CMD_ERR, suppose mmc_blk_cmd_err()
end request A completed and return zero. Continue the error handling,
suppose mmc_blk_reset() reset device success;
(5) Continue the execution, while loop completed because variable ret
is zero now;
(6) Finally, mmc_blk_issue_rw_rq() return without processing request B.
The process related to the missing request may wait that IO request
complete forever, possibly crashing the application or hanging the system.

When dma mapping (dma_map_sg) fails in sdhci_pre_dma_transfer, -EINVAL
is returned. There are 3 callers of sdhci_pre_dma_transfer:
* sdhci_pre_req and sdhci_adma_table_pre: handle negative return
* sdhci_prepare_data: handles 0 (error) and "else" (good) only
sdhci_prepare_data is therefore broken. When it receives -EINVAL from
sdhci_pre_dma_transfer, it assumes 1 sg mapping was mapped. Later,
this non-existent mapping with address 0 is kmap'ped and written to:
Corrupted low memory at ffff880000001000 (1000 phys) = 22b7d67df2f6d1cf
Corrupted low memory at ffff880000001008 (1008 phys) = 63848a5216b7dd95
Corrupted low memory at ffff880000001010 (1010 phys) = 330eb7ddef39e427
Corrupted low memory at ffff880000001018 (1018 phys) = 8017ac7295039bda
Corrupted low memory at ffff880000001020 (1020 phys) = 8ce039eac119074f

The hwrng output buffers (2) are cast inside of a a struct (caam_rng_ctx)
allocated in one DMA-tagged region. While the kernel's heap allocator
should place the overall struct on a cacheline aligned boundary, the 2
buffers contained within may not necessarily align. Consenquently, the ends
of unaligned buffers may not fully flush, and if so, stale data will be left
behind, resulting in small repeating patterns.
This fix aligns the buffers inside the struct.
Note that not all of the data inside caam_rng_ctx necessarily needs to be
DMA-tagged, only the buffers themselves require this. However, a fix would
incur the expense of error-handling bloat in the case of allocation failure.

Replace the NX842_MEM_COMPRESS define with a function that returns the
specific platform driver's required working memory size.
The common nx-842.c driver refuses to load if there is no platform
driver present, so instead of defining an approximate working memory
size that's the maximum approximate size of both platform driver's
size requirements, the platform driver can directly provide its
specific, i.e. sizeof(struct nx842_workmem), size requirements which
the 842-nx crypto compression driver will use.
This saves memory by both reducing the required size of each driver
to the specific sizeof() amount, as well as using the specific loaded
platform driver's required amount, instead of the maximum of both.

The include/linux/nx842.h header originally was there because the
crypto/842.c driver needed it to communicate with the nx-842 hw
driver. However, that crypto compression driver was moved into
the drivers/crypto/nx/ directory, and now can directly include the
nx-842.h header. Nothing else needs the public include/linux/nx842.h
header file, as all use of the nx-842 hardware driver will be through
the "842-nx" crypto compression driver, since the direct nx-842 api is
very limited in the buffer alignments and sizes that it will accept,
and the crypto compression interface handles those limitations and
allows any alignment and size buffers.
