A fix for unrecoverable SLB faults in the interrupt exit path, introduced by the recent rewrite of interrupt exit in C. Four fixes for our KUAP (Kernel Userspace Access Prevention) support on 64-bit. These are all fairly minor with the exception of the change to evaluate the get/put_user() arguments before we enable user access, which reduces the amount of code we run with user access enabled. A fix for our secure boot IMA rules, if enforcement of module signatures is enabled at runtime rather than build time. A fix to our 32-bit VDSO clock_getres() which wasn't falling back to the syscall for unknown clocks. A build fix for CONFIG_PPC_KUAP_DEBUG on 32-bit BookS, and another for 40x. Thanks to: Christophe Leroy, Hugh Dickins, Nicholas Piggin, Aurelien Jarno, Mimi Zohar, Nayna Jain. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEJFGtCPCthwEv2Y/bUevqPMjhpYAFAl6/z6ATHG1wZUBlbGxl cm1hbi5pZC5hdQAKCRBR6+o8yOGlgKM8D/9ibff532jpCewfwNNXztn3SxRpboQJ MgSpnqBlhjoezu84oPwGTPSBYiV/m4hVs5+vUVELKN1cvSmGFkRMoxI80MD3sPEj DWoyKmRpG2Uz6tSbU1H/1fA2MEHmG+saYE1g8k0S2m03mRluD4hcSW7jgHiTbFvc dC2i/fpf9SloHjEAu/3Wq/j3/6PI8pEoOvZozeLdusipLQgH7zODcW7noV1vF/pK BG4me8EVd7QImRRsJrPSlq/292wlSG6G+AwIlEYQbEv4rMqVNzc1WMPlBndHC27B ROT+84Ol1eX+jmbq+NTGpZFoWoozmZfTyEhVIQy8IMEiJjhsrh8nBLPP/KiDXjIA yujFgP4xfeLbYU+jydBrxun+Kd/DQxbnAIgJ3rJZdbGG2anqt9oWK+88+Y7rnnAY wjong1gQVPGr+y0Hj/6ahnXEs2En7W6dLw/EOHDRzazusFRj50a4JGAB1y2WAKHd yfa/6KWTUOvMvkkldPiIV1Uz+LFiUUGcHcnx67Fi19lj15W1JzTiHXqs15Ka0n8E X2n247d5rD55cS7owqfwBtso5zMlFITuPvr0lMv6hTP0bs0OuTiWCh+od3UeGKyy Rxa7piq3/8yB16cqEgbnQmcP0rkUD0WNGQamc2/02buD+GLV6DbgSSSDixUKyVJi 0/vi7nqaKVbIsg== =XkA+ -----END PGP SIGNATURE----- Merge tag 'powerpc-5.7-4' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: - A fix for unrecoverable SLB faults in the interrupt exit path, introduced by the recent rewrite of interrupt exit in C. - Four fixes for our KUAP (Kernel Userspace Access Prevention) support on 64-bit.
