This patch adds the include file to pull in __read_mostly on some architectures e.g. ppc and also fixes up signatures in generic asm. Reported-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Francesco Fusco <ffusco@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

/* General purpose hashing library
|
|
*
|
|
* That's a start of a kernel hashing library, which can be extended
|
|
* with further algorithms in future. arch_fast_hash{2,}() will
|
|
* eventually resolve to an architecture optimized implementation.
