commit e6d5e7d9 upstream. Commit 79c6ab50 (clk: divider: add CLK_DIVIDER_READ_ONLY flag) in v3.16 introduced the CLK_DIVIDER_READ_ONLY flag which caused the recalc_rate() and round_rate() clock callbacks to be omitted. However using this flag has the unfortunate side effect of causing the clock recalculation code when a clock rate change is attempted to always treat it as a pass-through clock, i.e. with a fixed divide of 1, which may not be the case. Child clock rates are then recalculated using the wrong parent rate. Therefore instead of dropping the recalc_rate() and round_rate() callbacks, alter clk_divider_bestdiv() to always report the current divider as the best divider so that it is never altered. For me the read only clock was the system clock, which divided the PLL rate by 2, from which both the UART and the SPI clocks were divided. Initial setting of the UART rate set it correctly, but when the SPI clock was set, the other child clocks were miscalculated. The UART clock was recalculated using the PLL rate as the parent rate, resulting in a UART new_rate of double what it should be, and a UART which spewed forth garbage when the rate changes were propagated.

commit c1aefbdd upstream. We can only use page_address on memory that has been mapped using kmap, when the buffer passed to the SPI has been allocated by vmalloc the page has not necessarily been mapped through kmap. This means sometimes page_address will return NULL causing the pointer we pass to sg_set_buf to be invalid. As we only call page_address so that we can pass a virtual address to sg_set_buf which will then immediately call virt_to_page on it, fix this by calling sg_set_page directly rather then relying on the sg_set_buf helper.

commit 0a8727e6 upstream. An IOCTL call that calls spi_setup() and then dw_spi_setup() will overwrite the persisted last transfer speed. On each transfer, the SPI speed is compared to the last transfer speed to determine if the clock divider registers need to be updated (did the speed change?). This bug was observed with the spidev driver using spi-config to update the max transfer speed. This fix: Don't overwrite the persisted last transaction clock speed when updating the SPI parameters in dw_spi_setup(). On the next transaction, the new speed won't match the persisted last speed and the hardware registers will be updated. On initialization, the persisted last transaction clock speed will be 0 but will be updated after the first SPI transaction. Move zeroed clock divider check into clock change test because chip->clk_div is zero on startup and would cause a divide-by-zero error. The calculation was wrong as well (can't support odd #).

commit 835f252c upstream. https://bugzilla.kernel.org/show_bug.cgi?id=86831 Markus reported that when shutting down mysqld (with AIO support, on a ext3 formatted Harddrive) leads to a negative number of dirty pages (underrun to the counter). The negative number results in a drastic reduction of the write performance because the page cache is not used, because the kernel thinks it is still 2 ^ 32 dirty pages open. Add a warn trace in __dec_zone_state will catch this easily: static inline void __dec_zone_state(struct zone *zone, enum zone_stat_item item) { atomic_long_dec(&zone->vm_stat[item]); + WARN_ON_ONCE(item == NR_FILE_DIRTY && atomic_long_read(&zone->vm_stat[item]) < 0); atomic_long_dec(&vm_stat[item]); } [ 21.341632] ------------[ cut here ]------------ [ 21.346294] WARNING: CPU: 0 PID: 309 at include/linux/vmstat.h:242 cancel_dirty_page+0x164/0x224() [ 21.355296] Modules linked in: wutbox_cp sata_mv [ 21.359968] CPU: 0 PID: 309 Comm: kworker/0:1 Not tainted 3.14.21-WuT #80 [ 21.366793] Workqueue: events free_ioctx [ 21.370760] [<c0016a64>] (unwind_backtrace) from [<c0012f88>] (show_stack+0x20/0x24) [ 21.378562] [<c0012f88>] (show_stack) from [<c03f8ccc>] (dump_stack+0x24/0x28) [ 21.385840] [<c03f8ccc>] (dump_stack) from [<c0023ae4>] (warn_slowpath_common+0x84/0x9c) [ 21.393976] [<c0023ae4>] (warn_slowpath_common) from [<c0023bb8>] (warn_slowpath_null+0x2c/0x34) [ 21.402800] [<c0023bb8>] (warn_slowpath_null) from [<c00c0688>] (cancel_dirty_page+0x164/0x224) [ 21.411524] [<c00c0688>] (cancel_dirty_page) from [<c00c080c>] (truncate_inode_page+0x8c/0x158) [ 21.420272] [<c00c080c>] (truncate_inode_page) from [<c00c0a94>] (truncate_inode_pages_range+0x11c/0x53c) [ 21.429890] [<c00c0a94>] (truncate_inode_pages_range) from [<c00c0f6c>] (truncate_pagecache+0x88/0xac) [ 21.439252] [<c00c0f6c>] (truncate_pagecache) from [<c00c0fec>] (truncate_setsize+0x5c/0x74) [ 21.447731] [<c00c0fec>] (truncate_setsize) from [<c013b3a8>] (put_aio_ring_file.isra.14+0x34/0x90) [ 21.456826] [<c013b3a8>] (put_aio_ring_file.isra.14) from [<c013b424>] (aio_free_ring+0x20/0xcc) [ 21.465660] [<c013b424>] (aio_free_ring) from [<c013b4f4>] (free_ioctx+0x24/0x44) [ 21.473190] [<c013b4f4>] (free_ioctx) from [<c003d8d8>] (process_one_work+0x134/0x47c) [ 21.481132] [<c003d8d8>] (process_one_work) from [<c003e988>] (worker_thread+0x130/0x414) [ 21.489350] [<c003e988>] (worker_thread) from [<c00448ac>] (kthread+0xd4/0xec) [ 21.496621] [<c00448ac>] (kthread) from [<c000ec18>] (ret_from_fork+0x14/0x20) [ 21.503884] ---[ end trace 79c4bf42c038c9a1 ]--- The cause is that we set the aio ring file pages as *DIRTY* via SetPageDirty (bypasses the VFS dirty pages increment) when init, and aio fs uses *default_backing_dev_info* as the backing dev, which does not disable the dirty pages accounting capability. So truncating aio ring file will contribute to accounting dirty pages (VFS dirty pages decrement), then error occurs. The original goal is keeping these pages in memory (can not be reclaimed or swapped) in life-time via marking it dirty. But thinking more, we have already pinned pages via elevating the page's refcount, which can already achieve the goal, so the SetPageDirty seems unnecessary. In order to fix the issue, using the __set_page_dirty_no_writeback instead of the nop .set_page_dirty, and dropped the SetPageDirty (don't manually set the dirty flags, don't disable set_page_dirty(), rely on default behaviour). With the above change, the dirty pages accounting can work well. But as we known, aio fs is an anonymous one, which should never cause any real write-back, we can ignore the dirty pages (write back) accounting by disabling the dirty pages (write back) accounting capability. So we introduce an aio private backing dev info (disabled the ACCT_DIRTY/WRITEBACK/ACCT_WB capabilities) to replace the default one. Reported-by:

commit ded94779 upstream. For LPAE, we have the following means for encoding writable or dirty ptes: L_PTE_DIRTY L_PTE_RDONLY !pte_dirty && !pte_write 0 1 !pte_dirty && pte_write 0 1 pte_dirty && !pte_write 1 1 pte_dirty && pte_write 1 0 So we can't distinguish between writeable clean ptes and read only ptes. This can cause problems with ptes being incorrectly flagged as read only when they are writeable but not dirty. This patch renumbers L_PTE_RDONLY from AP[2] to a software bit #58, and adds additional logic to set AP[2] whenever the pte is read only or not dirty. That way we can distinguish between clean writeable ptes and read only ptes. HugeTLB pages will use this new logic automatically. We need to add some logic to Transparent HugePages to ensure that they correctly interpret the revised pgprot permissions (L_PTE_RDONLY has moved and no longer matches PMD_SECT_AP2). In the process of revising THP, the names of the PMD software bits have been prefixed with L_ to make them easier to distinguish from their hardware bit counterparts. Signed-off-by:

commit f2950706 upstream. Long descriptors on ARM are 64 bits, and some pte functions such as pte_dirty return a bitwise-and of a flag with the pte value. If the flag to be tested resides in the upper 32 bits of the pte, then we run into the danger of the result being dropped if downcast. For example: gather_stats(page, md, pte_dirty(*pte), 1); where pte_dirty(*pte) is downcast to an int. This patch introduces a new macro pte_isset which performs the bitwise and, then performs a double logical invert (where needed) to ensure predictable downcasting. The logical inverse pte_isclear is also introduced. Equivalent pmd functions for Transparent HugePages have also been added. Signed-off-by:

commit 40df783d upstream. Intel Bluetooth devices that boot up in bootloader mode can not be used as generic HCI devices, but their HCI transport is still valuable and so bring that up as raw-only devices.

commit cde7fc87 upstream. The commit 2111667b ("ARM: pxa: call debug_ll_io_init for earlyprintk") triggers in the current kernel the attached backtrace on PXA/tosa early in the boot time when DEBUG_LL is enabled. It is due to overlap between uart virtual memory defined in DEBUG_UART_VIRT and mapped by debug_ll_io_init() and peripheral bus mapped by pxa_map_io at the same address, 0xf2100000. As hinted by Arnd, map early virtual memory for low level debug on address 0xf6200000, even if that means 2 virtual mappings will give access to the pxa internal UARTs (FFUART, BTUART, STUART, ...). ------------[ cut here ]------------ kernel BUG at /home/lumag/linux/mm/vmalloc.c:1143!

commit d2fa4a84 upstream. Only exchange source and destination filenames if flags contain RENAME_EXCHANGE. In case if executable file was running and replaced by other file /proc/PID/exe should still show correct file name, not the old name of the file by which it was replaced. The scenario when this bug manifests itself was like this: * ALT Linux uses rpm and start-stop-daemon; * during a package upgrade rpm creates a temporary file for an executable to rename it upon successful unpacking; * start-stop-daemon is run subsequently and it obtains the (nonexistant) temporary filename via /proc/PID/exe thus failing to identify the running process. Note that "long" filenames (> DNAiME_INLINE_LEN) are still exchanged without RENAME_EXCHANGE and this behaviour exists long enough (should be fixed too apparently). So this patch is just an interim workaround that restores behavior for "short" names as it was before changes introduced by commit da1ce067 ("vfs: add cross-rename"). See https://lkml.org/lkml/2014/9/7/6 for details. AV: the comments about being more careful with ->d_name.hash than with ->d_name.name are from back in 2.3.40s; they became obsolete by 2.3.60s, when we started to unhash the target instead of swapping hash chain positions followed by d_delete() as we used to do when dcache was first introduced.

commit 6f442be2 upstream. On a 32-bit kernel, this has no effect, since there are no IST stacks. On a 64-bit kernel, #SS can only happen in user code, on a failed iret to user space, a canonical violation on access via RSP or RBP, or a genuine stack segment violation in 32-bit kernel code. The first two cases don't need IST, and the latter two cases are unlikely fatal bugs, and promoting them to double faults would be fine. This fixes a bug in which the espfix64 code mishandles a stack segment violation. This saves 4k of memory per CPU and a tiny bit of code. Signed-off-by:
