8833272d87 crypto: drbg - self test for HMAC(SHA-512)
Considering that the HMAC(SHA-512) DRBG is the default DRBG now, a self
test is to be provided.

The test vector is obtained from a successful NIST ACVP test run.

6ee55a6f50 crypto: omap - Drop obsolete PageSlab check
As it is now legal to call flush_dcache_page on slab pages we
no longer need to do the check in the omap driver.  This patch
also uses flush_dcache_page instead of flush_kernel_dcache_page
because the page we're writing to could be anything.

2a96726bd0 crypto: nx - Fix RCU warning in nx842_OF_upd_status
The function nx842_OF_upd_status triggers a sparse RCU warning when
it directly dereferences the RCU-protected devdata.  This appears
to be an accident as there was another variable of the same name
that was passed in from the caller.

After it was removed (because the main purpose of using it, to
update the status member was itself removed) the global variable
unintenionally stood in as its replacement.

This patch restores the devdata parameter.

22ca9f4aaf crypto: shash - avoid comparing pointers to exported functions under CFI
crypto_shash_alg_has_setkey() is implemented by testing whether the
.setkey() member of a struct shash_alg points to the default version,
called shash_no_setkey(). As crypto_shash_alg_has_setkey() is a static
inline, this requires shash_no_setkey() to be exported to modules.

Unfortunately, when building with CFI, function pointers are routed
via CFI stubs which are private to each module (or to the kernel proper)
and so this function pointer comparison may fail spuriously.

Let's fix this by turning crypto_shash_alg_has_setkey() into an out of
line function.
