2021-07-27usb: isp1760: do not sleep in field register pollRui Miguel Silva
When polling for a setup or clear of a register field we were sleeping in atomic context but using a very tight sleep interval. Since the use cases for this poll mechanism are only in setup and stop paths, and in practice this poll is not used most of the times but needs to be there to comply to hardware setup times, remove the sleep time and make the poll loop tighter.

Due to no platforms use a multi-funtion pin to detect VBUS status until now when support dual role mode, prefer not to support it anymore; Another reason is that the controller doesn't support idle status, the dual role port works as device or as host, using an IDDIG pin is good enough, this will help to save another multi-function pin; And fix a typo of 'neede'; Last modify example using VBUS to turn on/off device, for device only mode, the driver doesn't get extcon.

2021-07-25smpboot: fix duplicate and misplaced inlining directiveLinus Torvalds
gcc doesn't care, but clang quite reasonably pointed out that the recent commit e9ba16e68cce ("smpboot: Mark idle_init() as __always_inlined to work around aggressive compiler un-inlining") did some really odd things: kernel/smpboot.c:50:20: warning: duplicate 'inline' declaration specifier [-Wduplicate-decl-specifier] static inline void __always_inline idle_init(unsigned int cpu) ^ which not only has that duplicate inlining specifier, but the new __always_inline was put in the wrong place of the function definition. We put the storage class specifiers (ie things like "static" and "extern") first, and the type information after that. And while the compiler may not care, we put the inline specifier before the types. So it should be just static __always_inline void idle_init(unsigned int cpu) instead.

Commit 71f642833284 ("ACPI: utils: Fix reference counting in for_each_acpi_dev_match()") started doing "acpi_dev_put()" on a pointer that was possibly NULL. That fails miserably, because that helper inline function is not set up to handle that case. Just make acpi_dev_put() silently accept a NULL pointer, rather than calling down to put_device() with an invalid offset off that NULL pointer.

2021-07-23riscv: __asm_copy_to-from_user: Fix: fail on RV32Akira Tsukamoto
Had a bug when converting bytes to bits when the cpu was rv32. The a3 contains the number of bytes and multiple of 8 would be the bits. The LGREG is holding 2 for RV32 and 3 for RV32, so to achieve multiple of 8 it must always be constant 3. The 2 was mistakenly used for rv32.

2021-07-23riscv: __asm_copy_to-from_user: Fix: overrun copyAkira Tsukamoto
There were two causes for the overrun memory access. The threshold size was too small. The aligning dst require one SZREG and unrolling word copy requires 8*SZREG, total have to be at least 9*SZREG. Inside the unrolling copy, the subtracting -(8*SZREG-1) would make iteration happening one extra loop. Proper value is -(8*SZREG).

2021-07-23hugetlbfs: fix mount mode command line processingMike Kravetz
In commit 32021982a324 ("hugetlbfs: Convert to fs_context") processing of the mount mode string was changed from match_octal() to fsparam_u32. This changed existing behavior as match_octal does not require octal values to have a '0' prefix, but fsparam_u32 does. Use fsparam_u32oct which provides the same behavior as match_octal.

2021-07-23mm: fix the deadlock in finish_fault()Qi Zheng
Commit 63f3655f9501 ("mm, memcg: fix reclaim deadlock with writeback") fix the following ABBA deadlock by pre-allocating the pte page table without holding the page lock. lock_page(A) SetPageWriteback(A) unlock_page(A) lock_page(B) lock_page(B) pte_alloc_one shrink_page_list wait_on_page_writeback(A) SetPageWriteback(B) unlock_page(B) # flush A, B to clear the writeback Commit f9ce0be71d1f ("mm: Cleanup faultaround and finish_fault() codepaths") reworked the relevant code but ignored this race. This will cause the deadlock above to appear again, so fix it.

2021-07-23mm: mmap_lock: fix disabling preemption directlyMuchun Song
Commit 832b50725373 ("mm: mmap_lock: use local locks instead of disabling preemption") fixed a bug by using local locks. But commit d01079f3d0c0 ("mm/mmap_lock: remove dead code for !CONFIG_TRACING configurations") changed those lines back to the original version. I guess it was introduced by fixing conflicts.
