Re: [linuxsh-dev] BUG fix for VMALLOC-ed page

[NIIBE Y. <gn...@ch...>]

My point is __not__:
	BIOS should set PCMCIA, kernel should not know about it.

But:
	If there're "wired" TLB entries, it's safe and better not
	to destroy them.

Most likely case is booting from ATA-card or Compact Flash, and
running on the file system on the card as if it's real ATA drive.  In
that case, BIOS enables MMU and sets a wired entry for I/O access.
