Commit 78d3bb44 ("kbuild: Fix <linux/version.h> for empty SUBLEVEL or PATCHLEVEL") fixed the build error for empty SUBLEVEL or PATCHLEVEL by prepending a zero. Commit 9b82f13e ("kbuild: clamp SUBLEVEL to 255") re-introduced this issue. This time, we cannot take the same approach because we have C code: #define LINUX_VERSION_PATCHLEVEL $(PATCHLEVEL) #define LINUX_VERSION_SUBLEVEL $(SUBLEVEL) Replace empty SUBLEVEL/PATCHLEVEL with a zero.

'make -s' should be really silent. However, 'make -s V=1' prints noisy log messages from some shell scripts. Of course, such a combination is odd, but the build system needs to do the right thing even if a user gives strange input. If -s is given, KBUILD_VERBOSE should be forced to 0. Signed-off-by:

Pull io_uring thread rewrite from Jens Axboe: "This converts the io-wq workers to be forked off the tasks in question instead of being kernel threads that assume various bits of the original task identity. This kills > 400 lines of code from io_uring/io-wq, and it's the worst part of the code. We've had several bugs in this area, and the worry is always that we could be missing some pieces for file types doing unusual things (recent /dev/tty example comes to mind, userfaultfd reads installing file descriptors is another fun one... - both of which need special handling, and I bet it's not the last weird oddity we'll find). With these identical workers, we can have full confidence that we're never missing anything. That, in itself, is a huge win. Outside of that, it's also more efficient since we're not wasting space and code on tracking state, or switching between different states. I'm sure we're go...

Current csky's swappon is broken by wrong swap PTE entry format. Now redesign the new format for abiv1 & abiv2 and make swappon + zram work properly on csky machines. C-SKY PTE has VALID, DIRTY to emulate PRESENT, READ, WRITE, EXEC attributes. GLOBAL bit is shared by two pages in the same tlb entry. So we need to keep GLOBAL, VALID, PRESENT zero in swp_pte. To distinguish PAGE_NONE and swp_pte, we need to use an additional bit (abiv1 is _PAGE_READ, abiv2 is _PAGE_WRITE). Signed-off-by:

Pull RISC-V updates from Palmer Dabbelt: "A handful of new RISC-V related patches for this merge window: - A check to ensure drivers are properly using uaccess. This isn't manifesting with any of the drivers I'm currently using, but may catch errors in new drivers. - Some preliminary support for the FU740, along with the HiFive Unleashed it will appear on. - NUMA support for RISC-V, which involves making the arm64 code generic. - Support for kasan on the vmalloc region. - A handful of new drivers for the Kendryte K210, along with the DT plumbing required to boot on a handful of K210-based boards. - Support for allocating ASIDs. - Preliminary support for kernels larger than 128MiB. - Various other improvements to our KASAN support, including the utilization of huge pages when allocating the KASAN regions. We may have already found a bug with the KASAN_VMALLOC code, but it's passing my tests. There's a fix in the works, but that will probably miss the merge window. * tag 'riscv-for-linus-5.12-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: (75 commits) riscv: Improve kasan population by using hugepages when possible riscv: Improve kasan population function riscv: Use KASAN_SHADOW_INIT define for kasan memory initialization riscv: Improve kasan definitions riscv: Get rid of MAX_EARLY_MAPPING_SIZE soc: canaan: Sort the Makefile alphabetically riscv: Disable KSAN_SANITIZE for vDSO riscv: Remove unnecessary declaration riscv: Add Canaan Kendryte K210 SD card defconfig riscv: Update Canaan Kendryte K210 defconfig riscv: Add Kendryte KD233 board device tree riscv: Add SiPeed MAIXDUINO board device tree riscv: Add SiPeed MAIX GO board device tree riscv: Add SiPeed MAIX DOCK board device tree riscv: Add SiPeed MAIX BiT board device tree riscv: Update Canaan Kendryte K210 device tree dt-bindings: add resets property to dw-apb-timer dt-bindings: fix sifive gpio properties dt-bindings: update sifive uart compatible string dt-bindings: update sifive clint compatible string ...
