Greetings;
I recently noticed this change via the linux-next tree.
It may not be possible to edit at this late date, but the change description refers to PROT_KERNEL, which is a symbol which does not appear to exist; perhaps PAGE_KERNEL was meant? The mismatch caused me and a couple other folks some confusion briefly until we decided it was supposed to be PAGE_KERNEL; if it's not too late, editing the description to clarify so would be nice.
Many thanks.
John Dorminy
