[to-be-updated] shmem-shmem_writepage-split-unlikely-i915-thp.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: shmem: shmem_writepage() split unlikely i915 THP has been removed from the -mm tree. Its filename was shmem-shmem_writepage-split-unlikely-i915-thp.patch This patch was dropped because an updated version will be merged ------------------------------------------------------ From: Hugh Dickins <hughd(a)google.com> Subject: shmem: shmem_writepage() split unlikely i915 THP drivers/gpu/drm/i915/gem/i915_gem_shmem.c contains a shmem_writeback() which calls shmem_writepage() from a shrinker: that usually works well enough; but if /sys/kernel/mm/transparent_hugepage/shmem_enabled has been set to "force" (documented as "Force the huge option on for all - very useful for testing"), shmem_writepage() is surprised to be called with a huge page, and crashes on the VM_BUG_ON_PAGE(PageCompound) (I did not find out where the crash happens when CONFIG_DEBUG_VM is off). LRU page reclaim always splits the shmem huge page first: I'd prefer not to demand that of i915, so check and split compound in shmem_writepage().

+ mm-gup-fix-gup_fast-with-dynamic-page-table-folding.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm/gup: fix gup_fast with dynamic page table folding has been added to the -mm tree. Its filename is mm-gup-fix-gup_fast-with-dynamic-page-table-folding.patch This patch should soon appear at https://ozlabs.org/~akpm/mmots/broken-out/mm-gup-fix-gup_fast-with-dynamic-… and later at https://ozlabs.org/~akpm/mmotm/broken-out/mm-gup-fix-gup_fast-with-dynamic-… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Vasily Gorbik <gor(a)linux.ibm.com> Subject: mm/gup: fix gup_fast with dynamic page table folding Currently to make sure that every page table entry is read just once gup_fast walks perform READ_ONCE and pass pXd value down to the next gup_pXd_range function by value e.g.: static int gup_pud_range(p4d_t p4d, unsigned long addr, unsigned long end, unsigned int flags, struct page **pages, int *nr) ... pudp = pud_offset(&p4d, addr); This function passes a reference on that local value copy to pXd_offset, and might get the very same pointer in return. This happens when the level is folded (on most arches), and that pointer should not be iterated. On s390 due to the fact that each task might have different 5,4 or 3-level address translation and hence different levels folded the logic is more complex and non-iteratable pointer to a local copy leads to severe problems. Here is an example of what happens with gup_fast on s390, for a task with 3-levels paging, crossing a 2 GB pud boundary: // addr = 0x1007ffff000, end = 0x10080001000 static int gup_pud_range(p4d_t p4d, unsigned long addr, unsigned long end, unsigned int flags, struct page **pages, int *nr) { unsigned long next; pud_t *pudp; // pud_offset returns &p4d itself (a pointer to a value on stack) pudp = pud_offset(&p4d, addr); do { // on second iteratation reading "random" stack value pud_t pud = READ_ONCE(*pudp); // next = 0x10080000000, due to PUD_SIZE/MASK != PGDIR_SIZE/MASK on s390 next = pud_addr_end(addr, end); ... } while (pudp++, addr = next, addr != end); // pudp++ iterating over stack return 1; } This happens since s390 moved to common gup code with commit d1874a0c2805 ("s390/mm: make the pxd_offset functions more robust") and commit 1a42010cdc26 ("s390/mm: convert to the generic get_user_pages_fast code"). s390 tried to mimic static level folding by changing pXd_offset primitives to always calculate top level page table offset in pgd_offset and just return the value passed when pXd_offset has to act as folded. What is crucial for gup_fast and what has been overlooked is that PxD_SIZE/MASK and thus pXd_addr_end should also change correspondingly. And the latter is not possible with dynamic folding. To fix the issue in addition to pXd values pass original pXdp pointers down to gup_pXd_range functions. And introduce pXd_offset_lockless helpers, which take an additional pXd entry value parameter.

patch "iio: adc: qcom-spmi-adc5: fix driver name" added to staging-linus

This is a note to let you know that I've just added the patch titled iio: adc: qcom-spmi-adc5: fix driver name to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From fdb29f4de1374483291232ae7515e5e7bb464762 Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov <dmitry.baryshkov(a)linaro.org> Date: Thu, 10 Sep 2020 16:59:51 +0300 Subject: iio: adc: qcom-spmi-adc5: fix driver name Remove superfluous '.c' from qcom-spmi-adc5 device driver name.

[PATCH] spi: spi-mtk-nor: fix timeout calculation overflow

by Chuanhong Guo

CLK_TO_US macro is used to calculate potential transfer time for various timeout handling. However it overflows on transfer bigger than 512 bytes because it first did (len * 8 * 1000000). This controller typically operates at 45MHz. This patch did 2 things: 1. calculate clock / 1000000 first 2. add a 4M transfer size cap so that the final timeout in DMA reading doesn't overflow Fixes: 881d1ee9fe81f ("spi: add support for mediatek spi-nor controller") Cc: <stable(a)vger.kernel.org> Signed-off-by: Chuanhong Guo <gch981213(a)gmail.com> --- drivers/spi/spi-mtk-nor.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/drivers/spi/spi-mtk-nor.c b/drivers/spi/spi-mtk-nor.c index 6e6ca2b8e6c82..619313db42c0e 100644 --- a/drivers/spi/spi-mtk-nor.c +++ b/drivers/spi/spi-mtk-nor.c @@ -89,7 +89,7 @@ // Buffered page program can do one 128-byte transfer #define MTK_NOR_PP_SIZE 128 -#define CLK_TO_US(sp, clkcnt) ((clkcnt) * 1000000 / sp->spi_freq) +#define CLK_TO_US(sp, clkcnt) DIV_ROUND_UP(clkcnt, sp->spi_freq / 1000000) struct mtk_nor { struct spi_controller *ctlr; @@ -177,6 +177,10 @@ static int mtk_nor_adjust_op_size(struct spi_mem *mem, struct spi_mem_op *op) if ((op->addr.nbytes == 3) || (op->addr.nbytes == 4)) { if ((op->data.dir == SPI_MEM_DATA_IN) && mtk_nor_match_read(op)) { + // limit size to prevent timeout calculation overflow + if (op->data.nbytes > 0x2000000) + op->data.nbytes = 0x2000000; + if ((op->addr.val & MTK_NOR_DMA_ALIGN_MASK) || (op->data.nbytes < MTK_NOR_DMA_ALIGN)) op->data.nbytes = 1; -- 2.26.2
