-stable review patch. If anyone has any objections, please let us know. --------------------- From: David Miller It was using an immediate _PAGE_EXEC_4U value in an 'and' instruction to perform the test. This doesn't work because the immediate field is signed 13-bit, this the mask being tested against the PTE was 0x1000 sign-extended to 32-bits instead of just plain 0x1000. Signed-off-by: David S.
