staging: zsmalloc: add mapping modes

2012-07-09T18:35:00+00:00

This patch improves mapping performance in zsmalloc by getting
usage information from the user in the form of a "mapping mode"
and using it to avoid unnecessary copying for objects that span
pages.

staging: zcache: remove unnecessary config option dependence

2012-07-09T18:31:15+00:00

zcache is enabled only if one of CONFIG_CLEANCACHE and CONFIG_FRONTSWAP is
enabled, see the Kconfig:
	depends on (CLEANCACHE || FRONTSWAP) && CRYPTO=y && X86
So, we can remove the check in the source code
