-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Linus,
Please pull some more powerpc fixes for 5.1. I was 50/50 on whether these were worthy of sending at rc6, but decided I would send them as they're in obscure areas of the code and they do fix user-visible bugs. cheers The following changes since commit cf7cf6977f531acd5dfe55250d0ee8cbbb6f1ae8: powerpc/mm: Define MAX_PHYSMEM_BITS for all 64-bit configs (2019-04-10 14:45:57 +1000) are available in the git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git tags/powerpc-5.1-6 for you to fetch changes up to 7a3a4d763837d3aa654cd1059030950410c04d77: powerpc/mm_iommu: Allow pinning large regions (2019-04-17 21:36:51 +1000) - ------------------------------------------------------------------ powerpc fixes for 5.1 #6 A one-liner to make our Radix MMU support depend on HUGETLB_PAGE. We use some of the hugetlb inlines (eg. pud_huge()) when operating on the linear mapping and if they're compiled into empty wrappers we can corrupt memory. Then two fixes to our VFIO IOMMU code. The first is not a regression but fixes the locking to avoid a user-triggerable deadlock. The second does fix a regression since rc1, and depends on the first fix. It makes it possible to run guests with large amounts of memory again (~256GB). Thanks to: Alexey Kardashevskiy. - ------------------------------------------------------------------ Alexey Kardashevskiy (2): powerpc/mm_iommu: Fix potential deadlock powerpc/mm_iommu: Allow pinning large regions Michael Ellerman (1): powerpc/mm/radix: Make Radix require HUGETLB_PAGE arch/powerpc/configs/skiroot_defconfig | 1 + arch/powerpc/mm/mmu_context_iommu.c | 97 ++++++++++++++++++++-------------- arch/powerpc/platforms/Kconfig.cputype | 2 +- 3 files changed, 60 insertions(+), 40 deletions(-) -----BEGIN PGP SIGNATURE----- iQIcBAEBAgAGBQJcxU1hAAoJEFHr6jzI4aWAafIP/2Bg4WFdvVfmfMFSxZPP/5Rg haS/4x6A6JJCVnxn0czaIUzY01s2Bgex4xAexoP1GtFTnNqXpWaxoPLveQQp0n4s lrRC2e5R2O5d9CHVC+qzkUk16Cd6RjrXLzz1YhJo2kQrERJ/CcPQPF2SNkg08kyz PtqrQVz2KMQsKiV/wPILwmOGLrxcJfH+01Z4/hbmJzveb9l4/SRN4aVZC12Wv7jQ HDszTeDTNpFpTysA+cqC95t0ZQRK+Hb0c23zsDqVVFZxAwf083ZcU9IXwVdhoSsp yXaoN/EFdTeVt8A4OL0/ER4wwyx1ShahvR1LuPDZ1x5/rzV0msExsNfRUOqeGUww K9KnYEi5wWes/o+aLgf4adG96swmTvVChOSe7OUpod1hPO3UZ8vMpeAt0XB527TY ptAcq7d6kpimd84A7qWM4lmC2QT9K5TqE9NoVpeCDgHbDqZZlWG2oMiXQXk/Thu2 OvpQwrbvX+vYgPgwuQbdyGnlNoxiTVT4oorsMo4YNIUi8OJB3Gu8ROL59tBjY/L+ jZFTNvj3fv/XYGy9mBBJhTpCG4SDz0D593iomrui+oAYczUkuNvlUv6lf9DCbXlU mVbuqMbFin1JUtPngXROQbKkaQ8pf0QgGBS3y7ipPrV/3vAyJ66SqIcrm8XsXyzl kAP6787TNrq3fosnfgBb =EDog -----END PGP SIGNATURE-----
