Subject2.5.67-mm1

http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.67-mm1.gz

Will appear sometime at

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.67/2.5.67-mm1/


. sparc64 is now using gcc-3.x, so there is a patch here to make gcc-2.95
the minimum required version.

. A few rmap-speedup patches reduce the rmap CPU tax by 25-30% on a P4

. Various other cleaups, speedups and fixups.
