Pull powerpc updates from Michael Ellerman: "Slightly late as I had to rebase mid-week to insert a bug fix: - A large series from Nick for 64-bit to further rework our exception vectors, and rewrite portions of the syscall entry/exit and interrupt return in C. The result is much easier to follow code that is also faster in general. - Cleanup of our ptrace code to split various parts out that had become badly intertwined with #ifdefs over the years. - Changes to our NUMA setup under the PowerVM hypervisor which should hopefully avoid non-sensical topologies which can lead to warnings from the workqueue code and other problems. - MAINTAINERS updates to remove some of our old orphan entries and update the status of others. - Quite a few other small changes and fixes all over the map.

selftests/powerpc: Add a test of bad (out-of-range) accesses

2020-01-06T05:25:27Z

Userspace isn't allowed to access certain address ranges, make sure we actually test that to at least some degree. This would have caught the recent bug where the SLB fault handler was incorrectly called on an out-of-range access when using the Radix MMU. It also would have caught the bug we had in get_region_id() where we were inserting SLB entries for bad addresses.

selftests/powerpc: Fix compile error on tlbie_test due to newer gcc

2019-10-09T06:16:59Z

Newer versions of GCC (>= 9) demand that the size of the string to be copied must be explicitly smaller than the size of the destination. Thus, the NULL char has to be taken into account on strncpy. This will avoid the following compiling error: tlbie_test.c: In function 'main': tlbie_test.c:639:4: error: 'strncpy' specified bound 100 equals destination size strncpy(logdir, optarg, LOGDIR_NAME_SIZE); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors Signed-off-by: Desnes A.

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.

This tests that when a process with a mapping above 512TB forks we correctly separate the parent and child address spaces. This exercises the bug in the context id handling fixed in the previous commit. Signed-off-by: Michael Ellerman
