Andi Kleen 944d2647dd [PATCH] x86_64: Drop global bit from early low mappings
Drop global bit from early low mappings

Suggested by Linus, originally also proposed by Suresh.

This fixes a race condition with early start of udev, originally
tracked down by Suresh B. Siddha. The problem was that switching
to the user space VM would not clear the global low mappings
for the beginning of memory, which lead to memory corruption.

Drop the global bits.

The kernel mapping stays global because it should stay constant.
