[RESEND][PATCH 0/2] Cleanup asm/scatterlist.h

I haven't gotten many responses so I'm going to try sending again (this time with a cover letter which I probably should have done in the first place...) ARCH_HAS_SG_CHAIN is currently defined as needed in asm/scatterlist.h. It was suggested[1] that this should probably be a proper Kconfig. At t

[RESEND][PATCH 1/2] lib/scatterlist: Make ARCH_HAS_SG_CHAIN an actual Kconfig

Rather than have architectures #define ARCH_HAS_SG_CHAIN in an architecture specific scatterlist.h, make it a proper Kconfig option and use that instead. At same time, remove the header files are are now mostly useless and just include asm-generic/scatterlist.h. Cc: Russell King Cc: Tony Luck Cc
