[PATCH] ARM: kuser: Fix incorrect cmpxchg syscall in kuser helpers

[Dave Martin]

The existing code invokes the syscall with rubbish in r7,
due to what looks like an incorrect literal load idiom.

Apparently this code is rarely used, so this may not be a tip-top-priority fix.

Applies cleanly on v2.6.37-rc1.
