[PATCH v2 1/5] crypto: ccree: correct host regs offset

by Gilad Ben-Yossef

The product signature and HW revision register have different offset on the older HW revisions. This fixes the problem of the driver failing sanity check on silicon despite working on the FPGA emulation systems.

[PATCH] libata: Drop SanDisk SD7UB3Q*G1001 NOLPM quirk

by Hans de Goede

Commit 184add2ca23c ("libata: Apply NOLPM quirk for SanDisk SD7UB3Q*G1001 SSDs") disabled LPM for SanDisk SD7UB3Q*G1001 SSDs. This has lead to several reports of users of that SSD where LPM was working fine and who know have a significantly increased idle power consumption on their laptops. Likely there is another problem on the T450s from the original reporter which gets exposed by the uncore reaching deeper sleep states (higher PC-states) due to LPM being enabled. The problem as reported, a hardfreeze about once a day, already did not sound like it would be caused by LPM and the reports of the SSD working fine confirm this. The original reporter is ok with dropping the quirk. A X250 user has reported the same hard freeze problem and for him the problem went away after unrelated updates, I suspect some GPU driver stack changes fixed things. TL;DR: The original reporters problem were triggered by LPM but not an LPM issue, so drop the quirk for the SSD in question.

Fix this up by properly allocating the data for the small "commands" that get sent to the device off of the stack. We do this for one command by having a whole urb just for ack messages, as they can be submitted in interrupt context, so we can not use usb_bulk_msg(). But the poweron command can sleep (and does), so use usb_bulk_msg() for that transfer.

[PATCH v4] rtc: sun6i: Fix bit_idx value for clk_register_gate

by Jagan Teki

From: Michael Trimarchi <michael(a)amarulasolutions.com> clk-gate core will take bit_idx through clk_register_gate and then do clk_gate_ops by using BIT(bit_idx), but rtc-sun6i is passing bit_idx as BIT(bit_idx) it becomes BIT(BIT(bit_idx) which is wrong and eventually external gate clock is not enabling.

Its filename is mm-huge_memoryc-__split_huge_page-use-atomic-clearpagedirty.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/mm-huge_memoryc-__split_huge_page-… and later at http://ozlabs.org/~akpm/mmotm/broken-out/mm-huge_memoryc-__split_huge_page-… 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: Hugh Dickins <hughd(a)google.com> Subject: mm/huge_memory.c: __split_huge_page() use atomic ClearPageDirty() Swapping load on huge=always tmpfs (with khugepaged tuned up to be very eager, but I'm not sure that is relevant) soon hung uninterruptibly, waiting for page lock in shmem_getpage_gfp()'s find_lock_entry(), most often when "cp -a" was trying to write to a smallish file. Debug showed that the page in question was not locked, and page->mapping NULL by now, but page->index consistent with having been in a huge page before. Reproduced in minutes on a 4.15 kernel, even with 4.17's 605ca5ede764 ("mm/huge_memory.c: reorder operations in __split_huge_page_tail()") added in; but took hours to reproduce on a 4.17 kernel (no idea why). The culprit proved to be the __ClearPageDirty() on tails beyond i_size in __split_huge_page(): the non-atomic __bitoperation may have been safe when 4.8's baa355fd3314 ("thp: file pages support for split_huge_page()") introduced it, but liable to erase PageWaiters after 4.10's 62906027091f ("mm: add PageWaiters indicating tasks are waiting for a page bit").

[PATCH v3 3/3] x86/mm: add TLB purge to free pmd/pte page interfaces

by Toshi Kani

ioremap() calls pud_free_pmd_page() / pmd_free_pte_page() when it creates a pud / pmd map. The following preconditions are met at their entry. - All pte entries for a target pud/pmd address range have been cleared. - System-wide TLB purges have been peformed for a target pud/pmd address range. The preconditions assure that there is no stale TLB entry for the range. Speculation may not cache TLB entries since it requires all levels of page entries, including ptes, to have P & A-bits set for an associated address. However, speculation may cache pud/pmd entries (paging-structure caches) when they have P-bit set. Add a system-wide TLB purge (INVLPG) to a single page after clearing pud/pmd entry's P-bit. SDM 4.10.4.1, Operation that Invalidate TLBs and Paging-Structure Caches, states that: INVLPG invalidates all paging-structure caches associated with the current PCID regardless of the liner addresses to which they correspond.

[Linux-stable-mirror] [PATCH 1/2] bdi: make sure congestion states are clear on free

by Tejun Heo

FUSE has a bug where it fails to clear congestion states if a connection gets aborted while congested, which can leave nr_wb_congested[] stuck until reboot causing wait_iff_congested() to wait spuriously. While the bdi owner, FUSE, is primarily responsible for clearing congestion states before destroying bdi_writebacks, bdi layer can ensure that congestion states are not leaked beyond bdi_writeback lifecycle.

[PATCH 3/4] branch-check: fix long->int truncation when profiling branches

by Mikulas Patocka

The function __builtin_expect returns long type (see the gcc documentation), and so do macros likely and unlikely. Unfortunatelly, when CONFIG_PROFILE_ANNOTATED_BRANCHES is selected, the macros likely and unlikely expand to __branch_check__ and __branch_check__ truncates the long type to int. This unintended truncation may cause bugs in various kernel code (we found a bug in dm-writecache because of it), so it's better to fix __branch_check__ to return long.

The changes are to make sure to check the operation status. Actually the flash write and erase error behavior is caused on our products. The flash is Macronix flash device MX29GL512FHT2I-11G used by our products. The patch series was separated for changes of flash write and erase. Since those were not depended each other at the time. But by additional changes the changes are related more as same way currently. So combine patch series for the flash write and erase changes as v6.
