perf events: Fix swevent hrtimer sampling by keeping track of remaining time when enabling/disabling swevent hrtimers
Make the hrtimer based events work for sysprof.
Whenever a swevent is scheduled out, the hrtimer is canceled.
When it is scheduled back in, the timer is restarted. This
happens every scheduler tick, which means the timer never
expired because it was getting repeatedly restarted over and
over with the same period.
To fix that, save the remaining time when disabling; when
reenabling, use that saved time as the period instead of the
user-specified sampling period.
Also, move the starting and stopping of the hrtimers to helper
functions instead of duplicating the code.

perf_event: Adjust frequency and unthrottle for non-group-leader events
The loop in perf_ctx_adjust_freq checks the frequency of sampling
event counters, and adjusts the event interval and unthrottles the
event if required, and resets the interrupt count for the event.
However, at present it only looks at group leaders.
This means that a sampling event that is not a group leader will
eventually get throttled, once its interrupt count reaches
sysctl_perf_event_sample_rate/HZ --- and that is guaranteed to
happen, if the event is active for long enough, since the interrupt
count never gets reset. Once it is throttled it never gets
unthrottled, so it basically just stops working at that point.
This fixes it by making perf_ctx_adjust_freq use ctx->event_list
rather than ctx->group_list. The existing spin_lock/spin_unlock
around the loop makes it unnecessary to put rcu_read_lock/
rcu_read_unlock around the list_for_each_entry_rcu().

This reverts commit
db8be50c4307dac2b37305fc59c8dc0f978d09ea, as per

http://marc.info/?l=linux-kernel&m=
125446885705223&w=4
We simply can't do the USB handoff at FIXUP_HEADER time, since it will
often require us to have valid IO mappings etc. But that in turn
requires a whole different approach, not this trivial one-liner.
Maybe we could teach all the USB quirk handoff handlers to only do the
quirk if the device has all its registers set up (since if it isn't
initialized, it's unlikely to be active), but regardless that will need
a whole lot more code than just saying "let's do it really early".
The proper fix is almost certainly to just leave the legacy IOMMU
mappings active until after all devices have been initialized.

USB: storage: When a device returns no sense data, call it a Hardware Error
This patch (as1294) fixes a problem that has plagued users for several
kernel releases. Some USB mass-storage devices don't return any sense
data when they encounter certain kinds of errors. The SCSI layer
interprets this to mean that the operation should be retried, and the
same thing happens -- over and over again with no limit. In some
circumstances (such as when a bus reset occurs) that is the right
thing to do, but not here.
The patch checks for this condition (a transport failure with no sense
data) and changes the result code to DID_ERROR and the sense code to
Hardware Error. This does get only a limited number of retries, and
so the command will fail relatively quickly instead of getting stuck
in an infinite loop.
This fixes a large part of Bugzilla #14118.

[ Arnd points out that we really should make sure parisc and alpha are
ok with this, since they have also been converted to use the generic
hardirq.h file. But neither seems to use it, although parisc does
build a IRQSTAT_SIRQ_PEND #define into asm-offsets - but that also
appears unused.. - Linus ]

Btrfs: fix file clone ioctl for bookend extents
The file clone ioctl was incorrectly taking the offset into the

The length never changes based on the offset into the physical extent.
Test case:
fallocate -l 1g image
mke2fs image
bcp image image2
e2fsck -f image2

The math bug ends up wrapping the length of the extent, and things
