Linus Torvalds bd7b12aa60 powerpc fixes for 5.13 #5 ... Fix our KVM reverse map real-mode handling since we enabled huge vmalloc (in some configurations). Revert a recent change to our IOMMU code which broke some devices. Fix KVM handling of FSCR on P7/P8, which could have possibly let a guest crash it's Qemu. Fix kprobes validation of prefixed instructions across page boundary. Thanks to: Alexey Kardashevskiy, Christophe Leroy, Fabiano Rosas, Frederic Barrat, Naveen N. Rao, Nicholas Piggin. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEJFGtCPCthwEv2Y/bUevqPMjhpYAFAmC8wi8THG1wZUBlbGxl cm1hbi5pZC5hdQAKCRBR6+o8yOGlgN42D/4vHCHX4T0CZ/5bwh1RMOoGKM+PFyLe BoA2i8lvUILG1+LOiRJuBnVZiWwKYBqfkkfY4BmQpU3Oe3gjbJJwc9QGGHUDarWn NmMPqVgaO5qXObObKXzBU1Ihq4UQwMhK044srzXcgMYyTnSFNgWQAsvO0+0Cl4K4 uT100AFV4tps8dLCHCq2XVHuQALnHzZah4yQ8i6u1TMN/TK+kXyONrMSCgsQ1mrM dDsT1zVeegj8EuW/n9kXkLNp2YZeatptZB7cPDtojlhCQTsZBcKnYtDq5ScASuwy 7hGjzA2SyWsa6l0Iejoj8tr/ZS8Nutftz3izuhDNLEf4foz0tOWqxbXJayOA5J7w vzs9OSFbT6z/svELSIkRCvfePqUdDdC2MthWoShgv0SoIXj+Y7ABKQRW9B5rLeF5 RiB2kCB+7S/03qjDtn57IlJC6aVoHzglTAdYXuj7guUEsZQrmtsdm1IM4eB0XYyx A9/AMCGSbswT0/IUriO4b9FtWGOJJf1vWv3WeqE63gPxqhyTz1ACqMT/0HLrARJZ /QLZrbuOSMBSGDnmJxy3vzb+3fxGxSGrUcoYc6MiSODuRgf7zHuRJsSDwoftnOTW PXVWPVz9ef0OEmuBJyEgTrO+/g9jjCPw8UJz9EaFzkMHbaoHRuZdo2m8X6zrXQLh AUVlDkkSmblY9w== =KkfQ -----END PGP SIGNATURE----- Merge tag 'powerpc-5.13-5' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: "Fix our KVM reverse map real-mode handling since we enabled huge vmalloc (in some configurations).
