asm	Merge tag 'powerpc-5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc updates from Michael Ellerman: "Notable changes: - Removal of the NPU DMA code, used by the out-of-tree Nvidia driver, as well as some other functions only used by drivers that haven't (yet?) made it upstream. - A fix for a bug in our handling of hardware watchpoints (eg. perf record -e mem: ...) which could lead to register corruption and kernel crashes. - Enable HAVE_ARCH_HUGE_VMAP, which allows us to use large pages for vmalloc when using the Radix MMU. - A large but incremental rewrite of our exception handling code to use gas macros rather than multiple levels of nested CPP macros. And the usual small fixes, cleanups and improvements.

Makefile	selftests/powerpc: Skip vmx/vsx/tar/etc tests on older CPUs Some of our tests use VSX or newer VMX instructions, so need to be skipped on older CPUs to avoid SIGILL'ing. Similarly TAR was added in v2.07, and the PMU event used in the stcx fail test only works on Power8 or later.

memcmp.c	selftests/powerpc: Include asm/cputable.h from utils.h utils.h provides have_hwcap() and have_hwcap2() which check for a feature bit. Those bits are defined in asm/cputable.h, so include it in utils.h so users of utils.h don't have to do it manually.

string.c	selftests/powerpc: Add test for strlen() This patch adds a test for strlen() string.c contains a copy of strlen() from lib/string.c The test first tests the correctness of strlen() by comparing the result with libc strlen(). It tests all cases of alignment. It them tests the duration of an aligned strlen() on a 4 bytes string, on a 16 bytes string and on a 256 bytes string.
