The WARN_ON check in arch_set_user_pkey_access() in the x86 architecture
fails to check for an invalid negative value.
A simple check for less than 0 would fix this issue however, in the call

From: Ira Weiny
The number of pkeys supported on x86 and powerpc are much smaller than a
u16 value can hold. It is desirable to standardize on the type for
pkeys. powerpc currently supports the most pkeys at 32. u8 is plenty
large for that.
Standardize on the pkey types by changing u16 to u8
From: Ira Weiny
Negative values passed to pkeyshift() will cause an overflow of the amr
and imar values. Pkey should not be negative in this call path and u8
is large enough for the 32 pkeys available on powerpc.
Change pkey to u8 in init_amr() and init_iamr().

These kmap() calls are localized to a single thread. To avoid the over
head of global PKRS update use the new kmap_thread() call instead.

There are 3 places in namei.c where the equivalent of ext2_put_page() is
open coded. We want to use k[un]map_thread() instead of k[un]map() in
ext2_[get|put]_page().
Move ext2_put_page() to ext2.h and use it in namei.c in prep for
converting the k[un]map() code.
