[linuxsh-cvs] CVS: linux/include/asm-sh/cpu-sh4 cacheflush.h,1.5,1.6

[Paul M. <le...@us...>]

Update of /cvsroot/linuxsh/linux/include/asm-sh/cpu-sh4
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv31115/include/asm-sh/cpu-sh4

Modified Files:
	cacheflush.h 
Log Message:
Cleanup of page table allocators, using generic folded PMD and PUD
helpers. TLB flushing operations are moved to a more sensible spot.

The page fault handler is also optimized slightly, we no longer waste
cycles on IRQ disabling for flushing of the page from the ITLB, since
we're already under CLI protection by the initial exception handler.
