Subject: Re: [PATCH] mtrr: fix types used in userspace exported header

From: Kyle McMartin <kyle@...hat.com>

Commit 932d27a7913fc6b3c64c6e6082628b0a1561dec9 exported some mtrr
structures without using the exportable __uX types, causing userspace
build failures.

Missed the u8 typedef below the struct.
