-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi Linus,
Please pull one more powerpc fix for 4.17: The following changes since commit c1d2a31397ec51f0370f6bd17b19b39152c263cb: powerpc/powernv: Fix NVRAM sleep in invalid context when crashing (2018-05-18 00:23:07 +1000) are available in the git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git tags/powerpc-4.17-7 for you to fetch changes up to faf37c44a105f3608115785f17cbbf3500f8bc71: powerpc/64s: Clear PCR on boot (2018-05-18 16:05:15 +1000) - ---------------------------------------------------------------- powerpc fixes for 4.17 #7 Just one fix, to make sure the PCR (Processor Compatibility Register) is reset on boot. Otherwise if we're running in compat mode in a guest (eg. pretending a Power9 is a Power8) and the host kernel oopses and kdumps then the kdump kernel's userspace will be running in Power8 mode, and will SIGILL if it uses Power9-only instructions. Thanks to: Michael Neuling. - ---------------------------------------------------------------- Michael Neuling (1): powerpc/64s: Clear PCR on boot arch/powerpc/kernel/cpu_setup_power.S | 6 ++++++ arch/powerpc/kernel/dt_cpu_ftrs.c | 1 + 2 files changed, 7 insertions(+) -----BEGIN PGP SIGNATURE----- iQIcBAEBCAAGBQJbB/bPAAoJEFHr6jzI4aWADOAP/iK5Tnxdd6NnVan9szsvmQpO TFwOB+/bYERdJfNIybe6IWCvMnRPpLWeL0tSbh9zcbx5O9QJgueOy/XxdzAvuDpk nexT03cCPS6llAcVI4HvhigfO4zUQB+pfSu5/XHjZGCqwAKP+OVBv8BuQbC6J6DV p8Kx1EpkG5kBvsN3OxwMCNjX4f99qpBEAWvDuV0Th0H1elr9kjNmkrSn6kV/56M3 MXpuAknP9QPBddiV2SbgMFw5WwmT31h3BAbTDJok64LcKVAw2PWO/YLMdYl27Gy2 6Zwern6hK9fy620JnPExNbNzME0tlgtBYpPOYUezsjg+XDxED+bwNrzEIb14HgcJ mtzd3TZUJ5GznlbxzeSso7LNsJ8CFG5k9zYtg80s3K67Z1BPosV/xXi/BR53iYDU fw+u4QqA1P/fp6wq3VWI37oyqbtMnBz/C0Lx1vbcFDBGs2rtz0+EmoBBQBxWAZ2Z CuWiuGyd+rOhMIcLX+KsnIKPLadrbj4s7EBYR+kZa7JnS2tvToLp5PjLpQaBUVSR vD6WzRRg2vH6/aicjRUjmduUCzBkaNtQjokkyv0kZqiUnnglxUbLvloprjZHEaKK VpBANpHV+N74lGwiGJFTKeEmxp6VDC7BQWSSWKvve8LwwcK6rhyQOoPPwo7NN7yp ubkeS/hnoX2H2YBP6BbT =3Iqr -----END PGP SIGNATURE-----
