2021-08-05bus: mhi: Add inbound buffers allocation flagLoic Poulain
Currently, the MHI controller driver defines which channels should have their inbound buffers allocated and queued. But ideally, this is something that should be decided by the MHI device driver instead, which actually deals with that buffers. Add a flag parameter to mhi_prepare_for_transfer allowing to specify if buffers have to be allocated and queued by the MHI stack. Keep auto_queue flag for now, but should be removed at some point.

2021-08-05misc: sram: Only map reserved areas in Tegra SYSRAMMikko Perttunen
On Tegra186 and later, a portion of the SYSRAM may be reserved for use by TZ. Non-TZ memory accesses to this portion, including speculative accesses, trigger SErrors that bring down the system. This does also happen in practice occasionally (due to speculative accesses). To fix the issue, add a flag to the SRAM driver to only map the device tree-specified reserved areas depending on a flag set based on the compatibility string. This would not affect non-Tegra systems that rely on the entire thing being memory mapped. If 64K pages are being used, we cannot exactly map the 4K regions that are placed in SYSRAM - ioremap code instead aligns to closest 64K pages. However, since in practice the non-accessible memory area is 64K aligned, these mappings do not overlap with the non-accessible memory area and things work out.

The functions get_online_cpus() and put_online_cpus() have been deprecated during the CPU hotplug rework. They map directly to cpus_read_lock() and cpus_read_unlock().

2021-08-01samples: mei: don't wait on read completion upon write.Alexander Usyskin
The original mei driver communication was strictly write command and receive response flow, the completion of write was determined when response was ready using select(). This paradigm is a long time not true. There can be write without a response and an unsolicited read. The driver is capable of handling those. Adjust also the sample code and remove select() on read() from the write flow. Add select to the read flow to showcase how to do the read with a timeout.

This patch exposes the feature revision information directly via the DFL device data structure.

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.

The N5010 features an FPGA that manages/interfaces four QSFP ports, and allows on-board custom packet processing/filtering/routing, based on logic loaded with user-provided FPGA bitstreams. The N5011 cards adds a PCIe switch that exposes, in addition to the FPGA itself, two Intel E810 (aka Columbiaville) ethernet controllers. With this, packets can be forwarded from the FPGA to the host for further processing.

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.
