On Linux x86_64 host with 32bit userspace, running
qemu or even just "qemu-img create -f qcow2 some.img 1G"
causes a kernel warning:
ioctl32(qemu-img:5296): Unknown cmd fd(3) cmd(00005326){t:'S';sz:0} arg(7fffffff) on some.img
ioctl32(qemu-img:5296): Unknown cmd fd(3) cmd(801c0204){t:02;sz:28} arg(fff77350) on some.img
ioctl 00005326 is CDROM_DRIVE_STATUS,
ioctl 801c0204 is FDGETPRM.
The warning appears because the Linux compat-ioctl handler for these
ioctls only applies to block devices, while qemu also uses the ioctls on
plain files.

Due to commit cdda911c34, evdev only
becomes readable when the buffer contains an EV_SYN/SYN_REPORT event. If
we get a repeat or a scancode we don't have a mapping for, we never call
input_sync, and thus those events don't get reported in a timely
fashion.
For example, take an mceusb transceiver with a default rc6 keymap. Press
buttons on an rc5 remote while monitoring with ir-keytable, and you'll
see nothing. Now press a button on the rc6 remote matching the keymap.
You'll suddenly get the rc5 key scancodes, the rc6 scancode and the rc6
key spit out all at the same time.
Pressing and holding a button on a remote we do have a keymap for also
works rather unreliably right now, due to repeat events also happening
without a call to input_sync (we bail from ir_do_keydown before getting
to the point where it calls input_sync).
Easy fix though, just add two strategically placed input_sync calls
right after our input_event calls for EV_MSC, and all is well again.
Technically, we probably should have been doing this all along, its just
that it never caused any functional difference until the referenced
change went into the input layer.
input_sync once per IR signal. There was another hidden bug in the code
where we were calling input_report_key using last_keycode instead of our
just discovered keycode, which manifested with the reordering of calling
input_report_key and setting last_keycode.

While 0xffdc devices have their IR protocol hard-coded into the firmware
of the device, we have no known way of telling what it is if we don't
have the device's config byte already in the driver. Unknown devices
default to the imon native protocol, but might actually be rc6, so we
should set the driver up such that the user can load the rc6 keytable

With hardware that has to use ir_raw_event_store_edge to collect IR
sample durations, we were not doing an event reset unless
IR_MAX_DURATION had passed. That's around 4 seconds. So if someone
presses up, then down, with less than 4 seconds in between, they'd get
the initial up, then up and down upon pressing down.
To fix this, I've lowered the "send a reset event" logic's threshold to
the input device's REP_DELAY (defaults to 500ms), and with an
saa7134-based GPIO-driven IR receiver in a Hauppauge HVR-1150, I get
*much* better behavior out of the remote now. Special thanks to Devin
for providing the hardware to investigate this issue.

There's really no good reason not to just grab the desired IRQ at driver
init time, instead of every time the lirc device node is accessed. This
also improves the speed and reliability with which a serial transmitter
can operate, as back-to-back transmission attempts (i.e., channel change
to a multi-digit channel) don't have to spend time acquiring and then
releasing the IRQ for every digit, sometimes multiple times, if lircd
has been told to use the min_repeat parameter.

Thanks to the intrepid testing and debugging of Matthijs van Drunen, it
was uncovered that at least some variants of the ITE8709 need to use pnp
resource 2, rather than 0, for things to function properly. Resource 0
has a length of only 1, and if you try to bypass the pnp_port_len check
and use it anyway (with either a length of 1 or 2), the system in
question's trackpad ceased to function.
The circa lirc 0.8.7 lirc_ite8709 driver used resource 2, but the value
was (amusingly) changed to 0 by way of a patch from ITE themselves, so I
don't know if there may be variants where 0 actually *is* correct, but
at least in this case and in the original lirc_ite8709 driver author's
case, it sure looks like 2 is the right value.
This fix should probably be applied to all stable kernels with the
ite-cir driver, lest we nuke more people's trackpads.

Currently, only open(2) is defined as the 'clearing' point. It has
two roles - first, it's an acknowledgement from userland indicating
that the event has been received and kernel can clear pending states
and proceed to generate more events. Secondly, it's passed on to
device drivers as a hint indicating that a synchronization point has
been reached and it might want to take a deeper look at the device.
The latter currently is only used by sr which uses two different
mechanisms - GET_EVENT_MEDIA_STATUS_NOTIFICATION and TEST_UNIT_READY
to discover events, where the former is lighter weight and safe to be
used repeatedly but may not provide full coverage. Among other
things, GET_EVENT can't detect media removal while TUR can.
This patch makes close(2) - blkdev_put() - indicate clearing hint for
MEDIA_CHANGE to drivers. disk_check_events() is renamed to
disk_flush_events() and updated to take @mask for events to flush
which is or'd to ev->clearing and will be passed to the driver on the
next ->check_events() invocation.
This change makes sr generate MEDIA_CHANGE when media is ejected from
userland - e.g. with eject(1).
Note: Given the current usage, it seems @clearing hint is needlessly
complex. disk_clear_events() can simply clear all events and the hint
can be boolean @flush.

During 32/64 NUMA init unification, commit 797390d855 ("x86-32,
NUMA: use sparse_memory_present_with_active_regions()") made
32bit mm init call memory_present() automatically from
active_regions instead of leaving it to each NUMA init path.
This commit description is inaccurate - memory_present() calls
aren't the same for flat and numaq. After the commit,
memory_present() is only called for the intersection of e820 and
NUMA layout. Before, on flatmem, memory_present() would be
called from 0 to max_pfn. After, it would be called only on the
areas that e820 indicates to be populated.
This is how x86_64 works and should be okay as memmap is allowed
to contain holes; however, x86_32 DISCONTIGMEM is missing
early_pfn_valid(), which makes memmap_init_zone() assume that
memmap doesn't contain any hole. This leads to the following
oops if e820 map contains holes as it often does on machine with
near or more 4GiB of memory by calling pfn_to_page() on a pfn

The DMA FIFO threshold registers and burst size registers have changed
for OMAP4. The current code only handles OMAP2/3 case, and so the
values are a bit off for OMAP4. A summary of the differences between
OMAP2/3 and OMAP4:
Burst size:
OMAP2/3: 4 x 32 bits / 8 x 32 bits / 16 x 32 bits
OMAP4: 2 x 128 bits / 4 x 128 bits / 8 x 128 bits
Threshold size:
OMAP2/3: in bytes (8 bit units)
OMAP4: in 128bit units
This patch fixes the issue by creating two new helper functions in
dss_features: dss_feat_get_buffer_size_unit() and
dss_feat_get_burst_size_unit(). These return (in bytes) the unit size
for threshold registers and unit size for burst size register,
respectively, and are used to calculate correct values.
For the threshold size the usage is straightforward. However, the burst
size register has different multipliers for OMAP2/3 and OMAP4. This
patch solves the problem by defining the multipliers for the burst size
as 2x, 4x and 8x, which fit fine for the OMAP4 burst size definition
(i.e. burst size unit for OMAP4 is 128bits), but requires a slight twist
on OMAP2/3 by defining the burst size unit as 64bit.
As the driver in practice always uses the maximum burst size, and no use
case currently exists where we would want to use a smaller burst size,
this patch changes the driver to hardcode the burst size when
initializing DISPC. This makes the threshold configuration code somewhat
simpler.

CPR is enabled via manager?/cpr_enable file, and the coefficient matrix
is set via manager?/cpr_coef file. The values in cpr_coef are in the
following order:

The overlay_cache_data and manager_cache_data structs include
the elements of omap_overlay_info and omap_overlay_manager_info
structs respectively. Include the structs instead of the individual
elements to reduce code.

OMAP2 doesn't have CPR, PRELOAD nor FIR_COEF_V registers. Add new
feature definitions for those, and check the feature before accessing
those registers.

OMAP3430 requires an 96MHz clock to VENC's DAC, but no other OMAP needs
it.
Add a new feature, FEAT_VENC_REQUIRES_TV_DAC_CLK, which tells if the
clock is needed on this platform, and use that feature in venc.c to
decide if the clock needs enabling.
