2020-04-17vdpa: allow a 32 bit vq alignmentMichael S. Tsirkin
get_vq_align returns u16 now, but that's not enough for systems/devices with 64K pages. All callers assign it to a u32 variable anyway, so let's just change the return value type to u32. Reported-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

Taking an interrupt (like the one being reconfigured) would lead to a deadlock. A solution to this is: - Reorder the locking so that meson_gpio_irq_update_bits takes the lock itself at all times, instead of relying on the caller to lock or not, hence making the RMW sequence atomic, - Rework the critical section in meson_gpio_irq_request_channel to only cover the allocation itself, and let the gpio_irq_sel_pin callback deal with its own locking if required, - Take the private spin-lock with interrupts disabled at all times Reviewed-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Marc Zyngier <maz@kernel.org>

2020-04-17irqchip/ti-sci-inta: Fix processing of masked irqsGrygorii Strashko
The ti_sci_inta_irq_handler() does not take into account INTA IRQs state (masked/unmasked) as it uses INTA_STATUS_CLEAR_j register to get INTA IRQs status, which provides raw status value. This causes hard IRQ handlers to be called or threaded handlers to be scheduled many times even if corresponding INTA IRQ is masked. Above, first of all, affects the LEVEL interrupts processing and causes unexpected behavior up the system stack or crash. Fix it by using the Interrupt Masked Status INTA_STATUSM_j register which provides masked INTA IRQs status.

After commit bfcb813203e619a8960a819bf533ad2a108d8105 ("net: dsa: configure the MTU for switch ports") my Lamobo R1 platform which uses an allwinner,sun7i-a20-gmac compatible Ethernet MAC started to fail by rejecting a MTU of 1536. The reason for that is that the DMA capabilities are not readable on this version of the IP, and there is also no 'tx-fifo-depth' property being provided in Device Tree. The property is documented as optional, and is not provided. Chen-Yu indicated that the FIFO sizes are 4KB for TX and 16KB for RX, so provide these values through platform data as an immediate fix until various Device Tree sources get updated accordingly.

2020-04-16xfs: move inode flush to the sync workqueueDarrick J. Wong
Move the inode dirty data flushing to a workqueue so that multiple threads can take advantage of a single thread's flushing work. The ratelimiting technique used in bdd4ee4 was not successful, because threads that skipped the inode flush scan due to ratelimiting would ENOSPC early, which caused occasional (but noticeable) changes in behavior and sporadic fstest regressions. Therefore, make all the writer threads wait on a single inode flush, which eliminates both the stampeding hordes of flushers and the small window in which a write could fail with ENOSPC because it lost the ratelimit race after even another thread freed space.

2020-04-16perf auxtrace: For reporting purposes, un-group AUX area eventAdrian Hunter
An AUX area event must be the group leader when recording traces in sample mode, but that does not produce the expected results from 'perf report' because it expects the leader to provide samples. Rather than teach 'perf report' about AUX area sampling, un-group the AUX area event during processing, making the 2nd event the leader.
