LoongArch: Remove clock setting during cpu hotplug stage

2022-07-29T10:22:32+00:00

On physical machine we can save power by disabling clock of hot removed cpu. However as different platforms require different methods to configure clocks, the code is platform-specific, and probably belongs to firmware/pmu or cpu regulator, rather than generic arch/loongarch code. Also, there is no such register on QEMU virt machine since the clock/frequency regulation is not emulated. This patch removes the hard-coded clock register accesses in generic LoongArch cpu hotplug flow. Reviewed-by: WANG Xuerui Signed-off-by: Bibo Mao Signed-off-by: Huacai Chen

mm: fix missing wake-up event for FSDAX pages

2022-07-18T22:07:51+00:00

FSDAX page refcounts are 1-based, rather than 0-based: if refcount is 1, then the page is freed. The FSDAX pages can be pinned through GUP, then they will be unpinned via unpin_user_page() using a folio variant to put the page, however, folio variants did not consider this special case, the result will be to miss a wakeup event (like the user of __fuse_dax_break_layouts()). This results in a task being permanently stuck in TASK_INTERRUPTIBLE state. Since FSDAX pages are only possibly obtained by GUP users, so fix GUP instead of folio_put() to lower overhead.

net: stmmac: switch to use interrupt for hw crosstimestamping

2022-07-18T10:14:35+00:00

Using current implementation of polling mode, there is high chances we will hit into timeout error when running phc2sys. Hence, update the implementation of hardware crosstimestamping to use the MAC interrupt service routine instead of polling for TSIS bit in the MAC Timestamp Interrupt Status register to be set.
