USB: fix interrupt disabling for HCDs with shared interrupt handlers

As has been discussed several times on LKML, IRQF_SHARED | IRQF_DISABLED
doesn't work reliably, i.e. a shared interrupt handler CAN'T be certain to
be called with interrupts disabled. Most USB HCD handlers use IRQF_DISABLED
and therefore havoc can break out if they share their interrupt with a
handler that doesn't use it.

On my test machine the yenta_socket interrupt handler (no IRQF_DISABLED)
was registered before ehci_hcd and one uhci_hcd instance. Therefore all
usb_hcd_irq() invocations for ehci_hcd and for one uhci_hcd instance
happened with interrupts enabled. That led to random lockups as USB core
HCD functions that acquire the same spinlock could be called twice
from interrupt handlers.

This patch updates usb_hcd_irq() to always disable/restore interrupts.
usb_add_hcd() will silently remove any IRQF_DISABLED requested from HCD code.

USB: ohci - record data toggle after unlink

This patch fixes a problem with OHCI where canceling bulk or
interrupt URBs may lose track of the right data toggle.  This
seems to be a longstanding bug, possibly dating back to the
Linux 2.4 kernel, which stayed hidden because

 (a) about half the time the data toggle bit was correct;
 (b) canceling such URBs is unusual; and
 (c) the few drivers which cancel these URBs either
      [1] do it only as part of shutting down, or
      [2] have fault recovery logic, which recovers.

For those transfer types, the toggle is normally written back
into the ED when each TD is retired.  But canceling bypasses
the mechanism used to retire TDs ... so on average, half the
time the toggle bit will be invalid after cancelation.

The fix is simple:  the toggle state of any canceled TDs are
propagated back to the ED in the finish_unlinks function.

how that timer is handled, so that short timeouts on the remaining

hrtimer: prevent migration for raising softirq

Due to a possible deadlock, the waking of the softirq was pushed outside
of the hrtimer base locks. See commit 0c96c5979a522c3323c30a078a70120e29b5bdbc

Unfortunately this allows the task to migrate after setting up the softirq
and raising it. Since softirqs run a queue that is per-cpu we may raise the
softirq on the wrong CPU and this will keep the queued softirq task from
running.

To solve this issue, this patch disables preemption around the releasing
of the hrtimer lock and raising of the softirq.

The non-NUMA case of build_zonelist_cache() would initialize the

Which is problematic, since non-NUMA only has a single node_zonelists[]
entry, and trying to zero the non-existent second one just overwrote the
nr_zones field instead.

As kswapd uses this value to determine what reclaim work is necessary,
the result is that kswapd never reclaims.  This causes processes to
