      ARM: S3C24XX: Fix s3c24xx build errors if !CONFIG_PM · fb630b9f
      Domenico Andreoli authored 
      v2:
- register_syscore_ops(&s3c24xx_irq_syscore_ops) does not need to be
  conditionally compiled out, it is already optimized out on !CONFIG_PM
- fix also s3c2412 and s3c2416 affected by the same build issue

v1:
s3c2440.c fails to build if !CONFIG_PM because in such case
s3c2410_pm_syscore_ops is not defined. Same error should happen also
in s3c2410.c and s3c2442.c

      crypto: ghash - Avoid null pointer dereference if no key is set · 7ed47b7d
      Nick Bowler authored 
      The ghash_update function passes a pointer to gf128mul_4k_lle which will
be NULL if ghash_setkey is not called or if the most recent call to
ghash_setkey failed to allocate memory.  This causes an oops.  Fix this
up by returning an error code in the null case.

This is trivially triggered from unprivileged userspace through the
AF_ALG interface by simply writing to the socket without setting a key.

The ghash_final function has a similar issue, but triggering it requires
a memory allocation failure in ghash_setkey _after_ at least one
successful call to ghash_update.

      ARM: S5P: fix offset calculation on gpio-interrupt · 1052cff3
      Marek Szyprowski authored 
      Offsets of the irq controller registers were calculated
correctly only for first GPIO bank. This patch fixes
calculation of the register offsets for all GPIO banks.
