2021-07-16ARM: multi_v7_defconfig: Make NOP_USB_XCEIV driver built-inStefan Wahren
The usage of usb-nop-xceiv PHY on Raspberry Pi boards with BCM283x has been a "regression source" a lot of times. The last case is breakage of USB mass storage boot has been commit e590474768f1 ("driver core: Set fw_devlink=on by default") for multi_v7_defconfig. As long as NOP_USB_XCEIV is configured as module, the dwc2 USB driver defer probing endlessly and prevent booting from USB mass storage device. So make the driver built-in as in bcm2835_defconfig and arm64/defconfig.

2021-07-16ARM: configs: Update u8500_defconfigLinus Walleij
The platform lost the framebuffer due to a commit solving a circular dependency in v5.14-rc1, so add it back in by explicitly selecting the framebuffer. The U8500 has also gained a few systems using touchscreens from Cypress, Melfas and Zinitix so add these at the same time as we're updating the defconfig anyway.

The ffa_linux_errmap buffer access index is supposed to range from 0-8 but it ranges from 1-9 instead. It reads one element out of bounds. It also changes the success into -EINVAL though ffa_to_linux_errno is never used in case of success, it is expected to work for success case too. It is slightly confusing code as the negative of the error code is used as index to the buffer. Fix it by negating it at the start and make it more readable.

2021-07-11mm/rmap: fix new bug: premature return from page_mlock_one()Hugh Dickins
In the unlikely race case that page_mlock_one() finds VM_LOCKED has been cleared by the time it got page table lock, page_vma_mapped_walk_done() must be called before returning, either explicitly, or by a final call to page_vma_mapped_walk() - otherwise the page table remains locked.

2021-07-11mm/rmap: fix old bug: munlocking THP missed other mlocksHugh Dickins
The kernel recovers in due course from missing Mlocked pages: but there was no point in calling page_mlock() (formerly known as try_to_munlock()) on a THP, because nothing got done even when it was found to be mapped in another VM_LOCKED vma. It's true that we need to be careful: Mlocked accounting of pte-mapped THPs is too difficult (so consistently avoided); but Mlocked accounting of only-pmd-mapped THPs is supposed to work, even when multiple mappings are mlocked and munlocked or munmapped. Refine the tests. There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so page_mlock_one() does not even have to worry about that complication. (I said the kernel recovers: but would page reclaim be likely to split THP before rediscovering that it's VM_LOCKED? I've not followed that up) Fixes: 9a73f61bdb8a ("thp, mlock: do not mlock PTE-mapped file huge pages") Signed-off-by: Hugh Dickins <hughd@google.com> Reviewed-by: Shakeel Butt <shakeelb@google.com> Acked-by: Kirill A.

2021-07-11mm/rmap: fix comments left over from recent changesHugh Dickins
Parallel developments in mm/rmap.c have left behind some out-of-date comments: try_to_migrate_one() also accepts TTU_SYNC (already commented in try_to_migrate() itself), and try_to_migrate() returns nothing at all. TTU_SPLIT_FREEZE has just been deleted, so reword the comment about it in mm/huge_memory.c; and TTU_IGNORE_ACCESS was removed in 5.11, so delete the "recently referenced" comment from try_to_unmap_one() (once upon a time the comment was near the removed codeblock, but they drifted apart).
