2017-11-30RISC-V: move empty_zero_page definition to C and export itOlof Johansson2-3/+3

2017-11-30RISC-V: io.h: type fixes for warningsOlof Johansson2-8/+10
include <linux/types.h> for __iomem definition. Also, add volatile to iounmap() like other architectures have it to avoid "discarding volatile" warnings from some drivers. Finally, explicitly promote the base address for INB/OUTB functions to avoid some old legacy drivers complaining about int-to-ptr promotions. The drivers are unlikely to work but they're included in allmodconfig so the warnings are noisy. Fixes, among other warnings, these with allmodconfig: ../arch/riscv/include/asm/io.h:24:21: error: expected '=', ',', ';', 'asm' or '__attribute__' before '*' token extern void __iomem *ioremap(phys_addr_t offset, unsigned long size); sound/pci/echoaudio/echoaudio.c: In function 'snd_echo_free': sound/pci/echoaudio/echoaudio.c:1879:10: warning: passing argument 1 of 'iounmap' discards 'volatile' qualifier from pointer target type [-Wdiscarded-qualifiers] Signed-off-by: Olof Johansson <[email protected]> Signed-off-by: Palmer Dabbelt <[email protected]>
2017-11-30RISC-V: use RISCV_{INT,SHORT} instead of {INT,SHORT} for asm macrosOlof Johansson2-9/+9
INT and SHORT are used by some drivers that pull in the include files, so prefixing helps avoid namespace conflicts. Other constructs in the same file already uses this.

2017-11-30xfs: Properly retry failed dquot items in case of error during buffer writebackCarlos Maiolino2-5/+49
Once the inode item writeback errors is already fixed, it's time to fix the same problem in dquot code. Although there were no reports of users hitting this bug in dquot code (at least none I've seen), the bug is there and I was already planning to fix it when the correct approach to fix the inodes part was decided. This patch aims to fix the same problem in dquot code, regarding failed buffers being unable to be resubmitted once they are flush locked. Tested with the recently test-case sent to fstests list by Hou Tao. Reviewed-by: Brian Foster <[email protected]> Signed-off-by: Carlos Maiolino <[email protected]> Reviewed-by: Darrick J.

2017-11-30gpio: 74x164: Fix crash during .remove()Geert Uytterhoeven1-2/+2
Commit 7ebc194d0fd4bb0f ("gpio: 74x164: Introduce 'enable-gpios' property") added a new member gpiod_oe to the end of the struct gen_74x164_chip, after the zero-length buffer array. However, this buffer is a flexible array, allocated together with the structure during .probe(). As the buffer is no longer the last member, writing to it corrupts the newly added member after it. During device removal, the corrupted member will be used as a pointer, leading to a crash. This went unnoticed, as the flexible array was declared as "buffer[0]" instead of "buffer[]", and thus did not trigger a "flexible array member not at end of struct" error from gcc. Move the gpiod_oe field up to fix this, and drop the zero from the array size to prevent future similar bugs.

2017-11-30drm/bridge: synopsys/dw-hdmi: Enable cec clockPierre-Hugues Husson1-0/+25
Support the "cec" optional clock. The documentation already mentions "cec" optional clock and it is used by several boards, but currently the driver doesn't enable it, thus preventing cec from working on those boards. And even worse: a /dev/cecX device will appear for those boards, but it won't be functioning without configuring this clock. Changes: v4: - Change commit message to stress the importance of this patch v3: - Drop useless braces v2: - Separate ENOENT errors from others - Propagate other errors (especially -EPROBE_DEFER) Signed-off-by: Pierre-Hugues Husson <[email protected]> Signed-off-by: Archit Taneja <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2017-11-30drm/bridge: adv7511/33: Fix adv7511_cec_init() failure handlingHans Verkuil3-25/+37
If the device tree for a board did not specify a cec clock, then adv7511_cec_init would return an error, which would cause adv7511_probe() to fail and thus there is no HDMI output. There is no need to have adv7511_probe() fail if the CEC initialization fails, so just change adv7511_cec_init() to a void function. In addition, adv7511_cec_init() should just return silently if the cec clock isn't found and show a message for any other errors. An otherwise correct cleanup patch from Dan Carpenter turned this broken failure handling into a kernel Oops, so bisection points to commit 7af35b0addbc ("drm/kirin: Checking for IS_ERR() instead of NULL") rather than 3b1b975003e4 ("drm: adv7511/33: add HDMI CEC support"). Based on earlier patches from Arnd and John.

2017-11-29fs/hugetlbfs/inode.c: change put_page/unlock_page order in hugetlbfs_fallocate()Nadav Amit1-2/+2
hugetlfs_fallocate() currently performs put_page() before unlock_page(). This scenario opens a small time window, from the time the page is added to the page cache, until it is unlocked, in which the page might be removed from the page-cache by another core. If the page is removed during this time windows, it might cause a memory corruption, as the wrong page will be unlocked. It is arguable whether this scenario can happen in a real system, and there are several mitigating factors. The issue was found by code inspection (actually grep), and not by actually triggering the flow. Yet, since putting the page before unlocking is incorrect it should be fixed, if only to prevent future breakage or someone copy-pasting this code. Mike said: "I am of the opinion that this does not need to be sent to stable. Although the ordering is current code is incorrect, there is no way for this to be a problem with current locking. In addition, I verified that the perhaps bigger issue with sys_fadvise64(POSIX_FADV_DONTNEED) for hugetlbfs and other filesystems is addressed in 3a77d214807c ("mm: fadvise: avoid fadvise for fs without backing device")" Link: http://lkml.kernel.org/r/[email protected] Fixes: 70c3547e36f5c ("hugetlbfs: add hugetlbfs_fallocate()") Signed-off-by: Nadav Amit <[email protected]> Reviewed-by: Mike Kravetz <[email protected]> Acked-by: Michal Hocko <[email protected]> Cc: Eric Biggers <[email protected]> Cc: Mike Kravetz <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2017-11-29mm/hugetlb: fix NULL-pointer dereference on 5-level paging machineKirill A. Shutemov1-1/+3
I made a mistake during converting hugetlb code to 5-level paging: in huge_pte_alloc() we have to use p4d_alloc(), not p4d_offset(). Otherwise it leads to crash -- NULL-pointer dereference in pud_alloc() if p4d table is not yet allocated. It only can happen in 5-level paging mode. In 4-level paging mode p4d_offset() always returns pgd, so we are fine.

2017-11-29autofs: revert "autofs: fix AT_NO_AUTOMOUNT not being honored"Ian Kent2-13/+5
Commit 42f461482178 ("autofs: fix AT_NO_AUTOMOUNT not being honored") allowed the fstatat(2) system call to properly honor the AT_NO_AUTOMOUNT flag but introduced a semantic change. In order to honor AT_NO_AUTOMOUNT a semantic change was made to the negative dentry case for stat family system calls in follow_automount(). This changed the unconditional triggering of an automount in this case to no longer be done and an error returned instead. This has caused more problems than I expected so reverting the change is needed. In a discussion with Neil Brown it was concluded that the automount(8) daemon can implement this change without kernel modifications. So that will be done instead and the autofs module documentation updated with a description of the problem and what needs to be done by module users for this specific case.
