Patch "Input: i8042 - enable MUX on Sony VAIO VGN-CS series to fix touchpad" has been added to the 3.18-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled Input: i8042 - enable MUX on Sony VAIO VGN-CS series to fix touchpad to the 3.18-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: input-i8042-enable-mux-on-sony-vaio-vgn-cs-series-to-fix-touchpad.patch and it can be found in the queue-3.18 subdirectory.

The touch sensor buttons on Sony VAIO VGN-CS series laptops (e.g. VGN-CS31S) are a separate PS/2 device. As the MUX is disabled for all VAIO machines by the nomux blacklist, the data from touch sensor buttons and touchpad are combined. The protocol used by the buttons is probably similar to the touchpad protocol (both are Synaptics) so both devices get enabled. The controller combines the data, creating a mess which results in random button clicks, touchpad stopping working and lost sync error messages: psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 4 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: issuing reconnect request Add a new i8042_dmi_forcemux_table whitelist with VGN-CS. With MUX enabled, touch sensor buttons are detected as separate device (and left disabled as there's currently no driver), fixing all touchpad problems.

Patch "fs/proc: Stop trying to report thread stacks" has been added to the 3.18-stable tree

This reverts more of: b76437579d13 ("procfs: mark thread stack correctly in proc/<pid>/maps") ... which was partially reverted by: 65376df58217 ("proc: revert /proc/<pid>/maps [stack:TID] annotation") Originally, /proc/PID/task/TID/maps was the same as /proc/TID/maps. In current kernels, /proc/PID/maps (or /proc/TID/maps even for threads) shows "[stack]" for VMAs in the mm's stack address range. In contrast, /proc/PID/task/TID/maps uses KSTK_ESP to guess the target thread's stack's VMA. This is racy, probably returns garbage and, on arches with CONFIG_TASK_INFO_IN_THREAD=y, is also crash-prone: KSTK_ESP is not safe to use on tasks that aren't known to be running ordinary process-context kernel code. This patch removes the difference and just shows "[stack]" for VMAs in the mm's stack range. This is IMO much more sensible -- the actual "stack" address really is treated specially by the VM code, and the current thread stack isn't even well-defined for programs that frequently switch stacks on their own.

In case of free space inode, this ends up with a warning in cow_file_range(). The same problem applies to btrfs_cross_ref_exist() since it may also read metadata in between. With this, run_delalloc_nocow() bails out when errors occur at the two places. cc: <stable(a)vger.kernel.org> v2.6.28+ Fixes: 17d217fe970d ("Btrfs: fix nodatasum handling in balancing code") Signed-off-by: Liu Bo <bo.li.liu(a)oracle.com> Signed-off-by: David Sterba <dsterba(a)suse.com> diff --git a/fs/btrfs/inode.c b/fs/btrfs/inode.c index 6504e63b2317..491a7397f6fa 100644 --- a/fs/btrfs/inode.c +++ b/fs/btrfs/inode.c @@ -1256,6 +1256,8 @@ static noinline int csum_exist_in_range(struct btrfs_fs_info *fs_info, list_del(&sums->list); kfree(sums); } + if (ret < 0) + return ret; return 1; } @@ -1388,10 +1390,23 @@ static noinline int run_delalloc_nocow(struct inode *inode, goto out_check; if (btrfs_extent_readonly(fs_info, disk_bytenr)) goto out_check; - if (btrfs_cross_ref_exist(root, ino, - found_key.offset - - extent_offset, disk_bytenr)) + ret = btrfs_cross_ref_exist(root, ino, + found_key.offset - + extent_offset, disk_bytenr); + if (ret) { + /* + * ret could be -EIO if the above fails to read + * metadata. + */ + if (ret < 0) { + if (cow_start != (u64)-1) + cur_offset = cow_start; + goto error; + } + + WARN_ON_ONCE(nolock); goto out_check; + } disk_bytenr += extent_offset; disk_bytenr += cur_offset - found_key.offset; num_bytes = min(end + 1, extent_end) - cur_offset; @@ -1409,10 +1424,22 @@ static noinline int run_delalloc_nocow(struct inode *inode, * this ensure that csum for a given extent are * either valid or do not exist. */ - if (csum_exist_in_range(fs_info, disk_bytenr, - num_bytes)) { + ret = csum_exist_in_range(fs_info, disk_bytenr, + num_bytes); + if (ret) { if (!nolock) btrfs_end_write_no_snapshotting(root); + + /* + * ret could be -EIO if the above fails to read + * metadata. + */ + if (ret < 0) { + if (cow_start != (u64)-1) + cur_offset = cow_start; + goto error; + } + WARN_ON_ONCE(nolock); goto out_check; } if (!btrfs_inc_nocow_writers(fs_info, disk_bytenr)) {

[PATCH] mm/memblock: fix potential issue in memblock_search_pfn_nid()

by Wei Yang

memblock_search_pfn_nid() returns the nid and the [start|end]_pfn of the memory region where pfn sits in. While the calculation of start_pfn has potential issue when the regions base is not page aligned. For example, we assume PAGE_SHIFT is 12 and base is 0x1234. Current implementation would return 1 while this is not correct. This patch fixes this by using PFN_UP(). The original commit is commit e76b63f80d93 ("memblock, numa: binary search node id") and merged in v3.12.

[patch 076/119] mm: hwpoison: disable memory error handling on 1GB hugepage

by akpm＠linux-foundation.org

From: Naoya Horiguchi <n-horiguchi(a)ah.jp.nec.com> Subject: mm: hwpoison: disable memory error handling on 1GB hugepage Recently the following BUG was reported: Injecting memory failure for pfn 0x3c0000 at process virtual address 0x7fe300000000 Memory failure: 0x3c0000: recovery action for huge page: Recovered BUG: unable to handle kernel paging request at ffff8dfcc0003000 IP: gup_pgd_range+0x1f0/0xc20 PGD 17ae72067 P4D 17ae72067 PUD 0 Oops: 0000 [#1] SMP PTI ... CPU: 3 PID: 5467 Comm: hugetlb_1gb Not tainted 4.15.0-rc8-mm1-abc+ #3 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.9.3-1.fc25 04/01/2014 You can easily reproduce this by calling madvise(MADV_HWPOISON) twice on a 1GB hugepage. This happens because get_user_pages_fast() is not aware of a migration entry on pud that was created in the 1st madvise() event. I think that conversion to pud-aligned migration entry is working, but other MM code walking over page table isn't prepared for it. We need some time and effort to make all this work properly, so this patch avoids the reported bug by just disabling error handling for 1GB hugepage.
