-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi Linus,
Please pull one more powerpc fix for 5.8: The following changes since commit f0479c4bcbd92d1a457d4a43bcab79f29d11334a: selftests/powerpc: Use proper error code to check fault address (2020-07-15 23:10:17 +1000) are available in the git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git tags/powerpc-5.8-8 for you to fetch changes up to 909adfc66b9a1db21b5e8733e9ebfa6cd5135d74: powerpc/64s/hash: Fix hash_preload running with interrupts enabled (2020-07-27 17:02:09 +1000) - ------------------------------------------------------------------ powerpc fixes for 5.8 #8 Fix a bug introduced by the changes we made to lockless page table walking this cycle. When using the hash MMU, and perf with callchain recording, we can deadlock if the PMI interrupts a hash fault, and the callchain recording then takes a hash fault on the same page. Thanks to: Nicholas Piggin, Aneesh Kumar K.V, Anton Blanchard, Athira Rajeev. - ------------------------------------------------------------------ Nicholas Piggin (1): powerpc/64s/hash: Fix hash_preload running with interrupts enabled arch/powerpc/kernel/exceptions-64s.S | 14 ++++++++--- arch/powerpc/mm/book3s64/hash_utils.c | 25 ++++++++++++++++++++ arch/powerpc/perf/core-book3s.c | 6 +++++ 3 files changed, 42 insertions(+), 3 deletions(-) -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEJFGtCPCthwEv2Y/bUevqPMjhpYAFAl8kFsQACgkQUevqPMjh pYAkbg/9HzJB8KbjAVJpoXHOf9+aHylhZKU2pcVtdoYE07VV6JabWnlI5flvTSEY 3Dvr3h/X0k2Z3n52+s1kYlW27ErU+o9Hbz1j4O41Ardiy14GmQ02FSi5iXjhKxuk AjX2MN76n1Te+1ee2Ib/Ubu8KOrbxLIya223tJ0TNu7RWuYVaCO/lNXPPTwm2JWI s9lryRAHNc4qkPMytsWi/gzNml3IP6cqnGVt1H5fmnOwQXUYbSjdmhBa7AwjCsA1 xJBMkxBxWOnUSknRCxaCCUTQ3sD+sJMzp6verlwEIb+HRh08iJyVzuWCpT9m0ZOG 5F3CvhIxwLatDsJ9N5EeGI2V4qBstBlHEUJJAjkwKgZxzmEm7j9H+ItAc421eo2A t/SYJTK4JltllCDyB22jCxdEgJh+opv8rki7U+INI01I8gHzqsr/0CHleGtMN5Cq fUBf25LOMUCpjeAO207j4DzeY6rTXz9H07XWrR4su//4S9bNkYUYpFfeE/3Kwwdq vZCxjm+fxxLPyAW+E2D2EGsyzIJootrAzly5T7gun8qwgCSgoCxI+YV9/DLmYaGf OjcG6+X58sfn1FTc8cD6udKCIMKh0JmSccZRqw1Ijp4EiGMnDZUbP9jg/aSciD8a +oco9QGvvxYQTMut4XUkXtqqZqaTISgWFD/QB9f4KGJ1Rs8tW5Y= =oaTB -----END PGP SIGNATURE-----
