Christophe Leroy b61c38baa9 powerpc/8xx: Fix STRICT_KERNEL_RWX startup test failure ... WRITE_RO lkdtm test works. But when selecting CONFIG_DEBUG_RODATA_TEST, the kernel reports rodata_test: test data was not read only This is because when rodata test runs, there are still old entries in TLB. Flush TLB after setting kernel pages RO or NX. Fixes: d5f17ee964 ("powerpc/8xx: don't disable large TLBs with CONFIG_STRICT_KERNEL_RWX") Cc: stable@vger.kernel.org # v5.1+ Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/485caac75f195f18c11eb077b0031fdd2bb7fb9e.1587361039.git.christophe.leroy@c-s.fr		2020-04-22 20:23:41 +10:00
