I have discovered that the current version of rtc-x1205.c does not work
correctly when asked to set the alarm time by the RTC_WKALM_SET ioctl()
call. This happens because the alarm registers do not behave like the
current-time registers. They are non-volatile. Two things go wrong:
- the X1205 requires a 10 msec delay after any attempt to write to the
non-volatile registers. The x1205_set_datetime() routine does the write
as 8 single-byte writes without any delay. Only the first write
succeeds. The second is NAKed because the chip is busy.
- the X1205 resets the RWEL bit after any write to the non-volatile
registers. This would lock out any further writes after the first even
with a 10msec delay.
I fix this by doing a single 8-byte write and then waiting 10msec for the
chip to be ready. A side effect of this change is that it will speed up
x1205_rtc_set_time() which uses the same code.
I have also implemented the 'enable' bit in the rtc_wkalm structure, which
the existing driver does not attempt to do. I have modified both
x1205_rtc_set_alarm() to set the AL0E bit, and x1205_rtc_read_alarm() to
return it.
I have tested this patch on a LinkSys NSLU2 under OpenWRT, but on no other
hardware. On the NSLU2 the X1205 correctly asserts its IRQ pin when the
alarm time matches the current time.

While 0e36a9a4a7 ("rtc: fix readback from
/sys/class/rtc/rtc?/wakealarm") made sure that active alarms were never
returned with invalid "wildcard" fields (negative), it can still report
(wrongly) that the alarm triggers in the past.
Example, if it's now 10am, an alarm firing at 5am will be triggered
TOMORROW not today. (Which may also be next month or next year...)
This updates that alarm handling in three ways:
* Handle alarm rollover in the common cases of RTCs that don't
support matching on all date fields.
* Skip the invalid-field logic when it's not needed.
* Minor bugfix ... tm_isdst should be ignored, it's one of the
fields Linux doesn't maintain.
A warning is emitted for some of the unhandled rollover cases, but the
possible combinations are a bit too numerous to handle every bit of
potential hardware and firmware braindamage.

Dirty page accounting accurately measures the amound of dirty pages in
writable shared mappings by mapping the pages RO (as indicated by
vma_wants_writenotify). We then trap on first write and call
set_page_dirty() on the page, after which we map the page RW and
continue execution.
When we launder dirty pages, we call clear_page_dirty_for_io() which
clears both the dirty flag, and maps the page RO again before we start
writeout so that the story can repeat itself.
vma_wants_writenotify() excludes VM_PFNMAP on the basis that we cannot
do the regular dirty page stuff on raw PFNs and the memory isn't going
anywhere anyway.
The recently introduced VM_MIXEDMAP mixes both !pfn_valid() and
pfn_valid() pages in a single mapping.
We can't do dirty page accounting on !pfn_valid() pages as stated
above, and mapping them RO causes them to be COW'ed on write, which
breaks VM_SHARED semantics.
Excluding VM_MIXEDMAP in vma_wants_writenotify() would mean we don't do
the regular dirty page accounting for the pfn_valid() pages, which
would bring back all the head-aches from inaccurate dirty page
accounting.
So instead, we let the !pfn_valid() pages get mapped RO, but fix them
up unconditionally in the fault path.

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.

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

This takes a more direct approach, reorganizing the code slightly to
be explicit about only the I/O watchdog role now being overridable.
It also replaces a now-obsolete comment describing older timer behavior.

Which is problematic, since non-NUMA only has a single node_zonelists[]

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
