[PATCH] ARM: 2698/1: Enable kernel r/w access to user pages on ARMv6
Patch from Catalin Marinas
cpu_v6_set_pte() sets the kernel access rights to r/o for user
pages (L_PTE_USER) when neither L_PTE_WRITE nor L_PTE_DIRTY are
set. This causes a kernel data abort when writing the TLS value
in the 0xffff0000 page. This patch enables the kernel r/w access.
