-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi Linus,
Please pull some more powerpc fixes for 5.5: The following changes since commit e42617b825f8073569da76dc4510bfa019b1c35a: Linux 5.5-rc1 (2019-12-08 14:57:55 -0800) are available in the git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git tags/powerpc-5.5-4 for you to fetch changes up to 228b607d8ea1b7d4561945058d5692709099d432: KVM: PPC: Book3S HV: Fix regression on big endian hosts (2019-12-17 15:09:08 +1100) - ------------------------------------------------------------------ powerpc fixes for 5.5 #4 Two weeks worth of accumulated fixes. A fix for a performance regression seen on PowerVM LPARs using dedicated CPUs, caused by our vcpu_is_preempted() returning true even for idle CPUs. One of the ultravisor support patches broke KVM on big endian hosts in v5.4. Our KUAP (Kernel User Access Prevention) code missed allowing access in __clear_user(), which could lead to an oops or erroneous SEGV when triggered via PTRACE_GETREGSET. Two fixes for the ocxl driver, an open/remove race, and a memory leak in an error path. A handful of other small fixes.
