Merge tag 'powerpc-5.2-1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman: "Slightly delayed due to the issue with printk() calling probe_kernel_read() interacting with our new user access prevention stuff, but all fixed now. The only out-of-area changes are the addition of a cpuhp_state, small additions to Documentation and MAINTAINERS updates. Highlights: - Support for Kernel Userspace Access/Execution Prevention (like SMAP/SMEP/PAN/PXN) on some 64-bit and 32-bit CPUs. This prevents the kernel from accidentally accessing userspace outside copy_to/from_user(), or ever executing userspace. - KASAN support on 32-bit. - Rework of where we map the kernel, vmalloc, etc. on 64-bit hash to use the same address ranges we use with the Radix MMU. - A rewrite into C of large parts of our idle handling code for 64-bit Book3S (ie. power8 & power9). - A fast path entry for syscalls on 32-bit CPUs, for a 12-17% speedup in the null_syscall benchmark. - On 64-bit bare metal we have support for recovering from errors with the time base (our clocksource), however if that fails currently we hang in __delay() and never crash. We now have support for detecting that case and short circuiting __delay() so we at least panic() and reboot. - Add support for optionally enabling the DAWR on Power9, which had to be disabled by default due to a hardware erratum. This has the effect of enabling hardware breakpoints for GDB, the downside is a badly behaved program could crash the machine by pointing the DAWR at cache inhibited memory. This is opt-in obviously. - xmon, our crash handler, gets support for a read only mode where operations that could change memory or otherwise disturb the system are disabled. Plus many clean-ups, reworks and minor fixes etc. Thanks to: Christophe Leroy, Akshay Adiga, Alastair D'Silva, Alexey Kardashevskiy, Andrew Donnellan, Aneesh Kumar K.V, Anju T Sudhakar, Anton Blanchard, Ben Hutchings, Bo YU, Breno Leitao, Cédric Le Goater, Christopher M.
