Re: [linuxsh-dev] Different old_mmap behavior in 2.4.5 and 2.4.8

My bad.

Bao, please try version 1.6 (former version) of arch/sh/kernel/sys_sh.c.

It did checks if the page is shared or not.  It does COLOUR_ALIGN the
address, only if it's shared.

At that time, I did find always COLOUR_ALIGN makes the performance
better (because of good cache hit), and didn't know it breaks
semantics and some applications.

I'll revert the change of following:

	* arch/sh/kernel/sys_sh.c (arch_get_unmapped_area): Always align
	to 16KB.
