3cd3a86b6f [MTD] [OneNAND] Avoid deadlock in erase callback; release chip lock first.
When the erase callback performs some other action on the flash, it's
highly likely to deadlock unless we actually release the chip lock
before calling it.

This patch mirrors that same change already done for NAND.

bb6c8d8fa9 HID: hiddev: Add 32bit ioctl compatibilty
The hiddev driver currently lacks 32bit ioctl compatibility, so
if you're running with a 64bit kernel and 32bit userspace, it won't
work.

I'm pretty sure that the only thing missing is a compat_ioctl
implementation as all structs have fixed size fields.

With this change I can use revoco to configure my MX Revolution mouse.

This patch fixes the problem, that Japanese MacBook doesn't recognize some keys
like '\'(yen, or backslash), '|'(pipe), and '_'(underscore).

It is due to that MacBook JIS keyboard (jp106) sends wrong report descriptor.
It saids "logical maximum = 0x65", so Keyboard.0089 is mapped to Key.Unknown,
while it should be accepted as Key.Yen.

0ce91cf9ce HID: enable hiddev for the SantaRosa MacBookPro IR receiver
The infrared remote receiver found in the SantaRosa MacBookPro
laptops (MacBookPro3,1) need to be forced to expose a HIDDEV
interface (instead of HIDINPUT) so that lirc can access it using
the 'macmini' driver.

The patch below adds the required quirk for forcing the HIDDEV
interface to be activated (HID_QUIRK_HIDDEV) and introduces a new
quirk which forces the HIDINPUT interface to be ignored
(HID_QUIRK_IGNORE_HIDINPUT).

Note that Apple calls this receiver 'IRController4' (info taken
from Apple's driver Info.plist). Older Mac{Book,Mini,Pro}s seem
to all use the 'IRController1' device (USB id 05ac:8240) which
doesn't need those quirks.

c01d50d181 HID: Report usage codes of keys as EV_MSC scancode events
Current HID layer does not report usage codes to the input layer. This feature
was previously removed, because it caused unnecessary storm of events in cases
of positioning devices, etc.

This patch adds reporting of usage codes as EV_MSC events only for key events.
We issue the EV_MSC event only if the state of the key corresponding to the
given code has changed, so that we don't report usages that are sent in every
report even if the state hasn't changed (for example Shift/Caps Lock/...
states as sent by various keyboards).

This functionality is required at least by KeyTouch in order to provide
convenient means for remapping the usage codes.

We have to ignore all non-LED usages in output fields if the
report descriptor of the device specifies any. If we don't do
so, the devices which contain the same usages both in input and

hid-input, we currently care only for the input usages, with exception
for LEDs. All other output usages should be properly handled by
appropriate force-feedback driver.

the field is not presented as bit-field by the keyboard. The keys can't

e8823bd63d UBI: fix atomic LEB change problems
When the UBI device is nearly full, i.e. all LEBs are mapped, we have
only one spare LEB left - the one we reserved for WL purposes. Well,
I do not count the LEBs which were reserved for bad PEB handling -
suppose NOR flash for simplicity. If an "atomic LEB change operation"
is run, and the WL unit is moving a LEB, we have no spare LEBs to
finish the operation and fail, which is not good. Moreover, if there
are 2 or more simultanious "atomic LEB change" requests, only one of
them has chances to succeed, the other will fail with -ENOSPC. Not
good either.

This patch does 2 things:
1. Reserves one PEB for the "atomic LEB change" operation.
2. Serealize the operations so that only on of them may run
   at a time (by means of a mutex).

b80e699812 [SPARC64]: Use sun4v VIRQ interfaces as intended.
We were simply concatenating the devhandle and devino and using that
as the cookie, which defeats the entire purpose of the VIRQ hypervisor
interfaces.

Now that we use physical addresses for the INO buckets, we can
allocate them dynamically for VIRQs and encode the cookies as
~__pa(bucket).  This allows us to test for and decode the cookie with
a simple:

	brlz	$reg1, 1f
	 xnor	$reg1, %g0, $reg2

sequence.

This works because bit 64 is never set in traditional
INO vectors, and it is also never set in a physical
address.  So xnor'ing the physical address of the bucket
always gives us a negative number, and thus a unique
condition we can test cheaply.

Inspired by ideas from Greg Onufer.
