[PATCH x86 for review II] [13/39] i386: CONFIG_PHYSICAL_ALIGN limited to 4M?

2007-02-11 Thread Andi Kleen

From: Rene Herman <[EMAIL PROTECTED]> A while ago it was remarked on list here that keeping the kernel 4M aligned physically might be a performance win if the added 1M (it normally loads at 1M) meant it would fit on one 4M aligned hugepage instead of 2 and since that time I've been doing such.
