2023-07-08net: bgmac: postpone turning IRQs off to avoid SoC hangsRafał Miłecki
Turning IRQs off is done by accessing Ethernet controller registers. That can't be done until device's clock is enabled. It results in a SoC hang otherwise. This bug remained unnoticed for years as most bootloaders keep all Ethernet interfaces turned on. It seems to only affect a niche SoC family BCM47189. It has two Ethernet controllers but CFE bootloader uses only the first one.

2023-07-07io_uring: Use io_schedule* in cqring waitAndres Freund
I observed poor performance of io_uring compared to synchronous IO. That turns out to be caused by deeper CPU idle states entered with io_uring, due to io_uring using plain schedule(), whereas synchronous IO uses io_schedule(). The losses due to this are substantial. On my cascade lake workstation, t/io_uring from the fio repository e.g. yields regressions between 20% and 40% with the following command: ./t/io_uring -r 5 -X0 -d 1 -s 1 -c 1 -p 0 -S$use_sync -R 0 /mnt/t2/fio/write.0.0 This is repeatable with different filesystems, using raw block devices and using different block devices. Use io_schedule_prepare() / io_schedule_finish() in io_cqring_wait_schedule() to address the difference. After that using io_uring is on par or surpassing synchronous IO (using registered files etc makes it reliably win, but arguably is a less fair comparison). There are other calls to schedule() in io_uring/, but none immediately jump out to be similarly situated, so I did not touch them. Similarly, it's possible that mutex_lock_io() should be used, but it's not clear if there are cases where that matters.

2023-07-07x86/smp: Don't send INIT to boot CPUThomas Gleixner
Parking CPUs in INIT works well, except for the crash case when the CPU which invokes smp_park_other_cpus_in_init() is not the boot CPU. Sending INIT to the boot CPU resets the whole machine. Prevent this by validating that this runs on the boot CPU. If not fall back and let CPUs hang in HLT.

2023-07-07ionic: remove dead device fail pathShannon Nelson

2023-07-07drm/fbdev-dma: Fix documented default preferred_bpp valueGeert Uytterhoeven
As of commit 6c80a93be62d398e ("drm/fb-helper: Initialize fb-helper's preferred BPP in prepare function"), the preferred_bpp parameter of drm_fb_helper_prepare() defaults to 32 instead of drm_mode_config.preferred_depth. Hence this also applies to drm_fbdev_dma_setup(), which just passes its own preferred_bpp parameter.

Husaini adds check to increment Qbv change error counter only on taprio Qbvs. He also removes delay during Tx ring configuration and resolves Tx hang that could occur when transmitting on a gate to be closed. Prasad Koya reports ethtool link mode as TP (twisted pair). Tee Min corrects value for max SDU.
