powerpc: Add support for relative exception tables

2016-11-14T00:11:51Z

This halves the exception table size on 64-bit builds, and it allows build-time sorting of exception tables to work on relocated kernels. Signed-off-by: Nicholas Piggin [mpe: Minor asm fixups and bits to keep the selftests working] Signed-off-by: Michael Ellerman

selftests/powerpc: Fail load_unaligned_zeropad on miscompare

2016-11-14T00:11:51Z

If the result returned by load_unaligned_zeropad() doesn't match what we expect we should fail the test! Signed-off-by: Michael Ellerman

selftests/powerpc: Abort load_unaligned_zeropad on unhandled SEGV

2016-11-14T00:11:51Z

If the load unaligned zeropad test takes a SEGV which can't be handled, we increment segv_error, print the offending NIP and then return without taking any further action. In almost all cases this means we'll just take the SEGV again, and loop eternally spamming the console. Instead just abort(), it's a fatal error in the test. The test harness will notice that the child died and print a nice message for us. Signed-off-by: Michael Ellerman

selftests/powerpc: Fix build failure of load_unaligned_zeropad test

2015-10-13T04:08:37Z

Commit 7a5692e6e533 ("arch/powerpc: provide zero_bytemask() for big-endian") added a call to __fls() in our word-at-a-time.h. That was fine for the kernel build but missed the fact that we also use word-at-a-time.h in a userspace test. Pulling in the kernel version of __fls() gets messy, so just define our own, it's unlikely to change often.

selftests/powerpc: Add test of load_unaligned_zero_pad()

2014-09-30T04:59:12Z

It is a rarely exercised case, so we want to have a test to ensure it works as required. Signed-off-by: Anton Blanchard Signed-off-by: Michael Ellerman
