<content type='text'>
The ARM allmodconfig build currently warngs because of the
ux500 crypto driver not working well with the jump label
implementation that we started using for dynamic debug, which
breaks building with 'gcc -O0':

In file included from /git/arm-soc/include/linux/jump_label.h:105:0,
                 from /git/arm-soc/include/linux/dynamic_debug.h:5,
                 from /git/arm-soc/include/linux/printk.h:289,
                 from /git/arm-soc/include/linux/kernel.h:13,
                 from /git/arm-soc/include/linux/clk.h:16,
                 from /git/arm-soc/drivers/crypto/ux500/hash/hash_core.c:16:
/git/arm-soc/arch/arm/include/asm/jump_label.h: In function 'hash_set_dma_transfer':
/git/arm-soc/arch/arm/include/asm/jump_label.h:13:7: error: asm operand 0 probably doesn't match constraints [-Werror]
  asm_volatile_goto("1:\n\t"

Turning off compiler optimizations has never really been supported
here, and it's only used when debugging the driver. I have not found
a good reason for doing this here, other than a misguided attempt
to produce more readable assembly output. Also, the driver is only
used in obsolete hardware that almost certainly nobody will spend
time debugging any more.

This just removes the -O0 flag from the compiler options.

The hash buffer is really HASH_BLOCK_SIZE bytes, someone
must have thought that memmove takes n*u32 words by mistake.
Tests work as good/bad as before after this patch.

<title>crypto: ux500 - fix checks of error code returned by devm_ioremap_resource()</title>

<id>b62917a2622ebcb03a500ef20da47be80d8c8951</id>
<content type='text'>
The change fixes potential oops while accessing iomem on invalid
address, if devm_ioremap_resource() fails due to some reason.

The devm_ioremap_resource() function returns ERR_PTR() and never
returns NULL, which makes useless a following check for NULL.

In the same time, we replace request_mem_region/ioremap by the unified

<title>crypto: drivers - Fix Kconfig selects</title>

<id>596103cf8fb0a258e1a5ed3e895860764490934d</id>
<content type='text'>
This patch fixes a number of problems in crypto driver Kconfig
entries:

1. Select BLKCIPHER instead of BLKCIPHER2.  The latter is internal
and should not be used outside of the crypto API itself.
2. Do not select ALGAPI unless you use a legacy type like
CRYPTO_ALG_TYPE_CIPHER.
3. Select the algorithm type that you are implementing, e.g., AEAD.
4. Do not select generic C code such as CBC/ECB unless you use them
as a fallback.
5. Remove default n since that is the default default.
