The change also solved a similar\n problem for MIPS which fortunately has time namespaces not yet\n enabled.\n\n S390 needs to update clock related VDSO data independent of the\n timekeeping updates. This was solved so far with yet another\n sequence counter in the S390 implementation. A better solution is\n to utilize the already existing VDSO sequence count for this. The\n core code now exposes helper functions which allow to serialize\n against the timekeeper code and against concurrent readers.\n\n S390 needs extra data for their clock readout function. The initial\n common VDSO data structure did not provide a way to add that.

Note,\n there are 2 non OpenRISC specific fixups.\n\n Non OpenRISC fixes:\n\n - In init we need to align the init_task correctly to fix an issue\n with MUTEX_FLAGS, reviewed by Peter Z. No one picked this up so I\n kept it on my tree.\n\n - In asm-generic/io.h I fixed up some sparse warnings, OK\u0027d by Arnd.\n Arnd asked to merge it via my tree.\n\n OpenRISC fixes:\n\n - Many fixes for OpenRISC sprase warnings.\n\n - Add support OpenRISC SMP tlb flushing rather than always flushing\n the entire TLB on every CPU.\n\n - Fix bug when dumping stack via /proc/xxx/stack of user threads\"\n\n* tag \u0027for-linus\u0027 of git://github.com/openrisc/linux:\n openrisc: uaccess: Add user address space check to access_ok\n openrisc: signal: Fix sparse address space warnings\n openrisc: uaccess: Remove unused macro __addr_ok\n openrisc: uaccess: Use static inline function in access_ok\n openrisc: uaccess: Fix sparse address space warnings\n openrisc: io: Fixup defines and move include to the end\n asm-generic/io.h: Fix sparse warnings on big-endian architectures\n openrisc: Implement proper SMP tlb flushing\n openrisc: Fix oops caused when dumping stack\n openrisc: Add support for external initrd images\n init: Align init_task to avoid conflict with MUTEX_FLAGS\n openrisc: fix __user in raw_copy_to_user()\u0027s prototype\n" }, { "commit": "7fca4dee610dffbe119714231cac0d59496bc193", "tree": "033049367ea586eb5725b7f3bd5bdceb168a6542", "parents": [ "0520058d0578c2924b1571c16281f873cb4a3d2b", "6553fb799f601497ca0703682e2aff131197dc5c" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Aug 14 13:40:27 2020 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Aug 14 13:40:27 2020 -0700" }, "message": "Merge tag \u0027powerpc-5.9-2\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux\n\nPull powerpc fix from Michael Ellerman:\n \"One fix for a boot crash on some platforms introduced by the recent\n pkey refactoring.\n\n Thanks to Christian Zigotzky and Aneesh Kumar K.V\"\n\n* tag \u0027powerpc-5.9-2\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux:\n powerpc/pkeys: Fix boot failures with Nemo board (A-EON AmigaOne X1000)\n" }, { "commit": "0520058d0578c2924b1571c16281f873cb4a3d2b", "tree": "d59fa88120a43dc90ec631508a0cbe13dc80e3ef", "parents": [ "cd94257d7a8103acf136e4bd46e3d0ad698a6f3d", "585c6ed738a5ed2a6fd7662fa1d82f25acfa85de" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Aug 14 13:34:37 2020 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Aug 14 13:34:37 2020 -0700" }, "message": "Merge tag \u0027for-linus-5.9-rc1b-tag\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip\n\nPull more xen updates from Juergen Gross:\n\n - Remove support for running as 32-bit Xen PV-guest.\n\n 32-bit PV guests are rarely used, are lacking security fixes for\n Meltdown, and can be easily replaced by PVH mode.
