When a device with an isochronous endpoint is plugged into the Intel
xHCI host controller, and the driver submits multiple frames per URB,
the xHCI driver will set the Block Event Interrupt (BEI) flag on all

an event on the event

This adds a missing break statement to VFIO_DEVICE_SET_IRQS handler
without which vfio_pci_set_err_trigger() would never be called.
While we are here, add another "break" to VFIO_PCI_REQ_IRQ_INDEX case
so if we add more indexes later, we won't miss it.

Request-based DM's blk-mq support defaults to off; but a user can easily
change the default using the dm_mod.use_blk_mq module/boot option.
Also, you can check what mode a given request-based DM device is using

Add a variant of blk_mq_init_queue that allows a previously allocated
queue to be initialized. blk_mq_init_allocated_queue models
blk_init_allocated_queue -- which was also created for DM's use.
DM's approach to device creation requires a placeholder request_queue be

This patchset updates request-based DM (used exclussively by DM
multipath) to support blk-mq I/O path or the old ->request_fn I/O
path -- the default is still the old ->request_fn I/O path.
Like was done for SCSI, I've exposed a dm-mod.ko 'use_blk_mq' module
parameter and a CONFIG_DM_MQ_DEFAULT.
dm_mq_queue_rq() is in atomic context so care must be taken to not
sleep -- as such GFP_ATOMIC is used for the md->bs bioset allocations
and dm-mpath's call to blk_get_request(). In the future the bioset
allocations will hopefully go away (by removing support for partial
completions of a request).
Commit e5863d9ad ("dm: allocate requests in target when stacking on
blk-mq devices") served as the first step toward fully utilizing blk-mq
in request-based DM -- it enabled stacking a old-style (request_fn)
request_queue ontop of the underlying blk-mq device(s). This first step
didn't improve per

Recently there's been some request for better sanity
checking in the time code, so that its more clear
when something is going wrong since timekeeping issues
could manifest in a large number of strange ways with
various subsystems.
Thus, this patch adds some extra infrastructure to
add a check upd
A long running project has been to cleanup remaining uses
of clocksource_register(), replacing it with the simpler
clocksource_register_khz/hz() functions.
However, there are a few cases where we need to self-define
our mult/shift values, so switch the function to a more
obviously internal __clock
In order to facilitate some clocksource validation,
add a max_cycles entry to the structure which will
hold the maximum cycle value that can safely be
multiplied without potentially causing an overflow.
