Certain boards seem to like to issue false overcurrent notifications, for
example on ports that don't have anything connected to them. This looks
like a hardware error, at the level of noise to those ports' overcurrent
input signals (or non-debounced VBUS comparators). This surfaces to users
as truly massive amounts of syslog spam from khubd (which is appropriate
for real hardware problems, except for the volume from multiple ports).
Using this new "ignore_oc" flag helps such systems work more sanely, by
preventing such indications from getting to khubd (and spam syslog). The
downside is of course that true overcurrent errors will be masked; they'll
appear as spontaneous disconnects, without the diagnostics that will let
users troubleshoot issues like short circuited cables.
Note that the bulk of these reports seem to be with VIA southbridges, but
I think some were with Intel ones.

and that kernel has most of the USB code ported to use the endpoint

This patch (as804) makes USB driver matching ignore the interface
class, subclass, and protocol if the device class is Vendor Specific.
Drivers can override this policy by specifying a Vendor ID as part
of the match; then vendor-specific matches are allowed.
Linus Walleij has reported a problem this patch fixes. When a
particular mass-storage device is switched from mass-storage mode to
Media Transfer Protocol, the interface class remains set to mass-storage
and usb-storage binds to it erroneously, even though the device class
changes to Vendor-Specific.
This may cause a problem for some drivers until their match records can
be updated to include Vendor IDs. But if it does, then those records
were broken to begin with.

Wireless USB Host Controllers accept a large number of devices per
host, which shows up as a large number of ports in its root hub.
When the number of ports in a hub device goes over 16, the activation
of the hub fails with the cryptic message in klogd.
hub 2-0:1.0: activate --> -22
Following this further, it was seen that:
hub_probe()
hub_configure()
generates pipe number
pseudo allocates buffer 'maxp' bytes in size using usb_maxpacket()
The endpoint descriptor for a root hub interrupt endpoint is
declared in
drivers/usb/core/hcd.c:hs_rh_config_descriptor and declares it
to be size two (supporting 15 devices max).
hub_activate()
usb_hcd_submit_urb()
rh_urb_enqueue()
urb->pipe is neither int nor ctl, so it errors out
rh_queue_status()
Returns -EINVAL because the buffer length is smaller
than the minimum needed to report all the hub port
bits as in accordance with USB2.0[11.12.3]. There has
to be trunc((PORTS + 1 + 7) / 8) bytes of space at
least.
Alan Stern confirmed that the reason for reading maxpktsize and not
the right amount is because some hubs are known to return more data
and thus cause overflow.
So this patch simply changes the code to make the interrupt endpoint's
max packet size be at least the minimum required by USB_MAXCHILDREN
(instead of a fixed magic number) and add documentation for that. This
way we are always ahead of the limit.

Current Wireless USB host hardware (Intel i1480 for example) allows up
to 22 devices to connect, thus bringing up the max number of children
in the WUSB Host Controller to 22 'fake' ports. Upcoming hardware
might raise that limit.
Makes almost no difference to go to 31, as the bit arrays are
byte-aligned (plus an extra bit in general), so 22 bits fit in 4 bytes
as 31 do.
As well, the only other array that depends on USB_MAXCHILDREN is
'struct usb_hub->indicator'. By declaring it 'u8' instead of 'enum
hub_led_mode', we reduce the size of each entry from 4 bytes (in i386)
to 1, which will add as we when are doubling USB_MAXCHILDREN
(with 16 the size of that array is 64 bytes, with 31 would be 128; by
using u8 that goes down to 31 bytes).

JMicron AHCI controllers set PORT_IRQ_IF_ERR on device errors. The
IRQ status bit indicates interface error or protocol mismatch and ahci
driver interprets it into AC_ERR_ATA_BUS. So, whenever an ATAPI
device raises check condition, ahci interprets it as ATA bus error and
thus resets it which, in turn, raises check condition thus creating a
reset loop and rendering the device unuseable.
This patch makes JMB controllers ignore PORT_IRQ_IF_ERR when
interpreting error condition.

- The warning was for rtc->irq_task_lock, gotten from rtc_update_irq()
by irq handlerss ... but in a handful of other cases, grabbed without
blocking IRQs.
- Some callers to rtc_update_irq() were not ensuring IRQs were blocked,
yet the routine expects that; make sure all callers block IRQs.
It would appear that RTC API tests haven't been part of anyone's kernel

Not all graphic page remappers support physical addresses over the 4GB
mark for remapping, so while some do (the AMD64 GART always did, and I
just fixed the i965 to do so properly), we're safest off just forcing
GFP_DMA32 allocations to make sure graphics pages get allocated in the
low 32-bit address space by default.
AGP sub-drivers that really care, and can do better, could just choose
to implement their own allocator (or we could add another "64-bit safe"
default allocator for their use), but quite frankly, you're not likely
to care in practice.
So for now, this trivial change means that we won't be allocating pages
that we can't map correctly by mistake on x86-64.
[ On traditional 32-bit x86, this could never happen, because GFP_KERNEL
would never allocate any highmem memory anyway ]

This introduces a i965-specific "mask_memory()" function that knows
about the extended physical addresses that the i965 supports. This

GTT.
Also simplify/clean-up the i965 case for the aperture sizing by just
returning the fixed 512kB size from "fetch_size()". We don't really
care that not all of the aperture may be visible - the only thing that
cares about the aperture size is the Intel "stolen memory" calculation,
which depends on the fixed size.

This same bug has now been introduced twice: it was done earlier by

last time in commit 72945b2b90.
We must NOT try to queue up notify handlers to another thread than the
normal ACPI execution thread, because the notifications on some systems
seem to just keep on accumulating until we run out of memory and/or
threads.
Keeping events within the one deferred execution thread automatically
throttles the events properly.
