[PATCH v2 0/6] Add support for pldw instruction on v7 MP cores

[Will Deacon]

Hello all,

Thie is version two of that patches I posted the other day:

v1: http://lists.infradead.org/pipermail/linux-arm-kernel/2013-July/185663.html

Changes since v1 include:

	- Rewrite prefetch and prefetchw as macros, to avoid explicit
	  casting in the caller (also requires changing the type of
	  arch_rwlock_t to remove the volatile member).

	- Some cosmetic cleanups.

Thanks to Nicolas for the feedback received so far.

Will
