6 years agomove libgcc.h to include/linux
Christoph Hellwig [Wed, 22 Nov 2017 10:47:28 +0000 (11:47 +0100)]
move libgcc.h to include/linux

Introducing a new include/lib directory just for this file totally
messes up tab completion for include/linux, which is highly annoying.

Move it to include/linux where we have headers for all kinds of other
lib/ code as well.

arm64: context: Fix comments and remove pointless smp_wmb()

The comments in the ASID allocator incorrectly hint at an MP-style idiom
using the asid_generation and the active_asids array. In fact, the
synchronisation is achieved using a combination of an xchg operation
and a spinlock, so update the comments and remove the pointless smp_wmb().
