2021-04-13memory: mtk-smi: Add device-link between smi-larb and smi-commonYong Wu
Normally, If the smi-larb HW need work, we should enable the smi-common HW power and clock firstly. This patch adds device-link between the smi-larb dev and the smi-common dev. then If pm_runtime_get_sync(smi-larb-dev), the pm_runtime_get_sync (smi-common-dev) will be called automatically. Also, Add DL_FLAG_STATELESS to avoid the smi-common clocks be gated when probe.

Commit 1a1c130ab757 ("ACPI: tables: x86: Reserve memory occupied by ACPI tables") attempted to address an issue with reserving the memory occupied by ACPI tables, but it broke the initrd-based table override mechanism relied on by multiple users. To restore the initrd-based ACPI table override functionality, move the acpi_boot_table_init() invocation in setup_arch() on x86 after the acpi_table_upgrade() one.

2021-04-13MIPS: Fix access_ok() for the last byte of user spacePaul Burton
The MIPS implementation of access_ok() incorrectly reports that access to the final byte of user memory is not OK, much as the alpha & SH versions did prior to commit 94bd8a05cd4d ("Fix 'acccess_ok()' on alpha and SH"). For example on a MIPS64 system with __UA_LIMIT == 0xffff000000000000 we incorrectly fail in the following cases: access_ok(0xffffffffffff, 0x1) = 0 access_ok(0xfffffffffffe, 0x2) = 0 Fix MIPS in the same way as alpha & SH, by subtracting one from the addr + size condition when size is non-zero. With this the access_ok() calls above return 1 indicating that the access may be valid. The cost of the improved check is pretty minimal - we gain 2410 bytes, or 0.03%, in kernel code size for a 64r6el_defconfig kernel built using GCC 8.1.0.

2021-04-13arm64/sve: Remove redundant system_supports_sve() testsMark Brown
Currently there are a number of places in the SVE code where we check both system_supports_sve() and TIF_SVE. This is a bit redundant given that we should never get into a situation where we have set TIF_SVE without having SVE support and it is not clear that silently ignoring a mistakenly set TIF_SVE flag is the most sensible error handling approach. For now let's just drop the system_supports_sve() checks since this will at least reduce overhead a little.

log_invalid sysctl allows values of 0 to 255 inclusive so we no longer need a range check: the min/max values can be removed.

2021-04-13arm64: kprobes: Restore local irqflag if kprobes is cancelledJisheng Zhang
If instruction being single stepped caused a page fault, the kprobes is cancelled to let the page fault handler continue as a normal page fault. But the local irqflags are disabled so cpu will restore pstate with DAIF masked. After pagefault is serviced, the kprobes is triggerred again, we overwrite the saved_irqflag by calling kprobes_save_local_irqflag(). NOTE, DAIF is masked in this new saved irqflag. After kprobes is serviced, the cpu pstate is retored with DAIF masked. This patch is inspired by one patch for riscv from Liao Chang.

2021-04-13can: peak_usb: peak_usb_probe(): make use of driver_infoMarc Kleine-Budde
There's no need to iterate over all supported adapters to find the struct peak_usb_adapter that describes the currently probed devices's capabilities. The driver core gives us the information for free, if we assign it to the struct usb_device_id::driver_info. This patch assigns the usb_device_id::driver_info and converts peak_usb_probe() to make use of it. This reduces the driver size by 100 bytes on ARCH=arm. | add/remove: 0/1 grow/shrink: 0/1 up/down: 0/-124 (-124) | Function old new delta | peak_usb_adapters_list 24 - -24 | peak_usb_probe 236 136 -100 | Total: Before=25263, After=25139, chg -0.49% Link: https://lore.kernel.org/r/20210406111622.1874957-6-mkl@pengutronix.de Acked-by: Stephane Grosjean <s.grosjean@peak-system.com> Tested-by: Stephane Grosjean <s.grosjean@peak-system.com> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
