2020-06-16arm64: pgtable: Clear the GP bit for non-executable kernel pagesWill Deacon
Commit cca98e9f8b5e ("mm: enforce that vmap can't map pages executable") introduced 'pgprot_nx(prot)' for arm64 but collided silently with the BTI support during the merge window, which endeavours to clear the GP bit for non-executable kernel mappings in set_memory_nx(). For consistency between the two APIs, clear the GP bit in pgprot_nx().

2020-06-16ARM: dts: am5729: beaglebone-ai: fix rgmii phy-modeDrew Fustini
Since commit cd28d1d6e52e ("net: phy: at803x: Disable phy delay for RGMII mode") the networking is broken on the BeagleBone AI which has the AR8035 PHY for Gigabit Ethernet [0]. The fix is to switch from phy-mode = "rgmii" to phy-mode = "rgmii-rxid". Note: Grygorii made a similar DT fix for other AM57xx boards with a different phy in commit 820f8a870f65 ("ARM: dts: am57xx: fix networking on boards with ksz9031 phy").

While testing the recent suspend and resume regressions I noticed that duovero can still end up losing edge gpio interrupts on runtime suspend.

2020-06-16afs: Fix use of afs_check_for_remote_deletion()David Howells

However, it's being called from the operation success functions, where no abort has happened - and if an inline abort is recorded, it's handled by afs_vnode_commit_status(). Fix this by actually calling the operation aborted method if provided and having that point to afs_check_for_remote_deletion().

2020-06-16libceph: move away from global osd_req_flagsIlya Dryomov
osd_req_flags is overly general and doesn't suit its only user (read_from_replica option) well: - applying osd_req_flags in account_request() affects all OSD requests, including linger (i.e. watch and notify). However, linger requests should always go to the primary even though some of them are reads (e.g. notify has side effects but it is a read because it doesn't result in mutation on the OSDs). - calls to class methods that are reads are allowed to go to the replica, but most such calls issued for "rbd map" and/or exclusive lock transitions are requested to be resent to the primary via EAGAIN, doubling the latency. Get rid of global osd_req_flags and set read_from_replica flag only on specific OSD requests instead.

2020-06-16s390/vdso: Use $(LD) instead of $(CC) to link vDSONathan Chancellor
Currently, the VDSO is being linked through $(CC). This does not match how the rest of the kernel links objects, which is through the $(LD) variable. When clang is built in a default configuration, it first attempts to use the target triple's default linker, which is just ld. However, the user can override this through the CLANG_DEFAULT_LINKER cmake define so that clang uses another linker by default, such as LLVM's own linker, ld.lld. This can be useful to get more optimized links across various different projects. However, this is problematic for the s390 vDSO because ld.lld does not have any s390 emulatiom support: https://github.com/llvm/llvm-project/blob/llvmorg-10.0.1-rc1/lld/ELF/Driver.cpp#L132-L150 Thus, if a user is using a toolchain with ld.lld as the default, they will see an error, even if they have specified ld.bfd through the LD make variable: $ make -j"$(nproc)" -s ARCH=s390 CROSS_COMPILE=s390x-linux-gnu- LLVM=1 \ LD=s390x-linux-gnu-ld \ defconfig arch/s390/kernel/vdso64/ ld.lld: error: unknown emulation: elf64_s390 clang-11: error: linker command failed with exit code 1 (use -v to see invocation) Normally, '-fuse-ld=bfd' could be used to get around this; however, this can be fragile, depending on paths and variable naming. The cleaner solution for the kernel is to take advantage of the fact that $(LD) can be invoked directly, which bypasses the heuristics of $(CC) and respects the user's choice. Similar changes have been done for ARM, ARM64, and MIPS.

2020-06-16s390/qdio: reduce SLSB writes during Input Queue processingJulian Wiedmann
Streamline the processing of QDIO Input Queues, and remove some intermittent SLSB updates (no deleting of old ACKs, no redundant transitions through NOT_INIT). Rather than counting ACKs, we now keep track of the whole batch of SBALs that were completed during the current polling cycle. Most completed SBALs stay in their initial state (ie. PRIMED or ERROR), except that the most recent SBAL in each sub-run is ACKed for IRQ reduction. The only logic changes happen in inbound_handle_work(), the other delta is just a renaming of the variables that track the SBAL batch. Note that in particular we don't need to flip the _oldest_ SBAL to an idle state (eg. NOT_INIT or ACKed) as a guard against catching our own tail. Since get_inbound_buffer_frontier() will never scan more than the remaining nr_buf_used SBALs, this scenario just doesn't occur.

For mono channel, SSI will switch to Normal mode. In Normal mode and Network mode, the Word Length Control bits control the word length divider in clock generator, which is different with I2S Master mode (the word length is fixed to 32bit), it should be the value of params_width(hw_params). The condition "slots == 2" is not good for I2S Master mode, because for Network mode and Normal mode, the slots can also be 2. Then we need to use (ssi->i2s_net & SSI_SCR_I2S_MODE_MASK) to check if it is I2S Master mode. So we refine the formula for mono channel, otherwise there will be sound issue for S24_LE.
