I believe the following change will fix the cache/TLB inconsistency observed by Meelis. After changing the page table entries, we need to flush the cache and TLB to ensure that we don't have any stale PTE values in the cache or TLB. The alternative patching is done after all CPUs are running. Thus, we need to flush the whole cache and TLB. I included the init section in the range modified by map_pages as suggested by Helge. Some routines in the init section may require patching. Signed-off-by: NJohn David Anglin <dave.anglin@bell.net> Signed-off-by: NHelge Deller <deller@gmx.de>

There are only two 64-bit architecture ports that have a 32-bit suseconds_t: sparc64 and parisc64. I've encountered a number of problems with this, while trying to get a proper 64-bit time_t working on 32-bit architectures. Having a 32-bit suseconds_t combined with a 64-bit time_t means that we get extra padding in data structures that may leak kernel stack data to user space, and it breaks all code that assumes that timespec and timeval have the same layout. While we can't change sparc64, it seems that glibc on parisc64 has always set suseconds_t to 'long', and the current version would give incorrect results for gettimeofday() and many other interfaces: timestamps passed from user space into the kernel result in tv_usec being always zero (the lower bits contain the intended value but are ignored) while data passed from the kernel to user space contains either zeroes or random data in tv_usec. Based on that, it seems best to change the user API in the kernel in an incompatible way to match what glibc expects. Note that the distros I could find (gentoo and debian) all just have 32-bit user space, which does not suffer from this problem.

Merge tag 'riscv-for-linus-4.20-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux Pull RISC-V updates from Palmer Dabbelt: "This patch set contains a lot (at least, for me) of improvements to the RISC-V kernel port: - The removal of some cacheinfo values that were bogus. - On systems with F but without D the kernel will not show the F extension to userspace, as it isn't actually supported. - Support for futexes. - Removal of some unused code. - Cleanup of some menuconfig entries. - Support for systems without a floating-point unit, and for building kernels that will never use the floating-point unit. - More fixes to the RV32I port, which regressed again. It's really time to get this into a regression test somewhere so I stop breaking it. Thanks to Zong for resurrecting it again! - Various fixes that resulted from a year old review of our original patch set that I finally got around to. - Various improvements to SMP support, largely based around having switched to logical hart numbering, as well as some interrupt improvements. This one is in the same patch set as above, thanks to Atish for sheparding everything though as my patch set was a bit of a mess. I'm pretty sure this is our largest patch set since the original kernel contribution, and it's certainly the one with the most contributors. While I don't have anything else I know I'm going to submit for the merge window, I would be somewhat surprised if I didn't screw anything up.

Pull btrfs updates from David Sterba: "This is the first batch with fixes and some nice performance improvements. Preliminary results show eg. more files/sec in fsmark, better perf on multi-threaded workloads (filebench, dbench), fewer context switches and overall better memory allocation characteristics (multiple benchmarks). Apart from general performance, there's an improvement for qgroups + balance workload that's been troubling our users. Note for stable: there are 20+ patches tagged for stable, out of 90. Not all of them apply cleanly on all stable versions but the conflicts are mostly due to simple cleanups and resolving should be obvious. The fixes are otherwise independent. Performance improvements: - transition between blocking and spinning modes of path is gone, which originally resulted to more unnecessary wakeups and updates to the path locks, the effects are measurable and improve latency and scalability - qgroups: first batch of changes that should speedup balancing with qgroups on, skip quota accounting on unchanged subtrees, overall gain is about 30+% in runtime - use rb-tree with cached first node for several structures, small improvement to avoid pointer chasing Fixes: - trim - fix: some blockgroups could have been missed if their logical address was past the total filesystem size (ie. after a lot of balancing) - better error reporting, after processing blockgroups and whole device - fix: continue trimming block groups after an error is encountered - check for trim support of the device earlier and avoid some unnecessary work - less interaction with transaction commit that improves latency on slower storage (eg. image files over NFS) - fsync - fix warning when replaying log after fsync of a O_TMPFILE - fix wrong dentries after fsync of file that got its parent replaced - qgroups: fix rescan that might misc some dirty groups - don't clean dirty pages during buffered writes, this could lead to lost updates in some corner cases - some block groups could have been delayed in creation, if the allocation triggered another one - error handling improvements Cleanups: - removed unused struct members and variables - function return type cleanups - delayed refs code refactoring - protect against deadlock that could be caused by crafted image that tries to allocate from a tree that's locked already" * tag 'for-4.20-part1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (93 commits) btrfs: switch return_bigger to bool in find_ref_head btrfs: remove fs_info from btrfs_should_throttle_delayed_refs btrfs: remove fs_info from btrfs_check_space_for_delayed_refs btrfs: delayed-ref: pass delayed_refs directly to btrfs_delayed_ref_lock btrfs: delayed-ref: pass delayed_refs directly to btrfs_select_ref_head btrfs: qgroup: move the qgroup->members check out from (!qgroup)'s else branch btrfs: relocation: Remove redundant tree level check btrfs: relocation: Cleanup while loop using rbtree_postorder_for_each_entry_safe btrfs: qgroup: Avoid calling qgroup functions if qgroup is not enabled Btrfs: fix wrong dentries after fsync of file that got its parent replaced Btrfs: fix warning when replaying log after fsync of a tmpfile btrfs: drop min_size from evict_refill_and_join btrfs: assert on non-empty delayed iputs btrfs: make sure we create all new block groups btrfs: reset max_extent_size on clear in a bitmap btrfs: protect space cache inode alloc with GFP_NOFS btrfs: release metadata before running delayed refs Btrfs: kill btrfs_clear_path_blocking btrfs: dev-replace: remove pointless assert in write unlock btrfs: dev-replace: move replace members out of fs_info ...
