musb_hdrc: Cannot stall an endpoint 0 control transfer from a data stage cal lback function
Gadget drivers are supposed to be able to cause EP0 protocol stalls by
issuing an appropriate request from the callback issued when the DATA
stage completes ... not only from the setup() callback or from some
thread that decides how to handle the request.
This fix is based on a patch from Geoffrey Tam <geoffrey@evertz.com>,
and addresses that by updating the endpoint state AFTER the callback
is issued, providing the correct IRQ-acking CSR to the halt() so it
can just mask in the SEND_STALL bit, and ensuring that only the CSR
is still written only once even on this new code path.
Also includes a few small cleanups: avoid "this" variable name, and
pack device bitfields more efficiently (wasting less space).

ARM: OMAP: abstract debug card setup (smc, leds)
Additional cleanup for debug boards on H2/P2/H3/H4: move the init
code that's not board-specific into a new file where it can be easily
shared between all the different boards (avoiding code duplication,
and making it easier to support more devices). Make H4 use that.
This should be easy to drop in to the OMAP1 boards using these debug
cards; the only difference seems to be that the p2 does an extra reset
of the smc using the fpga (probably all boards could do that, if it's
necessary) and doesn't use the gpio mux or request APIs.

ARM: OMAP: omap2/gpmc updates
GPMC updates:
- bugfixes: wrong/missing flags, omitted write, wrong test
- don't map memory segments starting at zero
- improve debug messaging
- export gpmc_get_fclk_perio]d() since it's needed to calc timings
- expect gpmc_cs_set_timings() caller to have initialized sync vs async
Note that this API is glitchy; likely the best fix would be to add
a member to "struct gpmc_timings" to hold GPMC_CONFIG1, since that
holds one key aspect of the GPMC timings (the gpmc_fclk divisor,
and sync vs. async == whether that divisor matters).

dio: zero struct dio with kzalloc instead of manually
This patch uses kzalloc to zero all of struct dio rather than manually
trying to track which fields we rely on being zero. It passed aio+dio
stress testing and some bug regression testing on ext3.
This patch was introduced by Linus in the conversation that lead up to
Badari's minimal fix to manually zero .map_bh.b_state in commit:
I was unable to measure a stable difference in the number of cpu cycles
spent in blockdev_direct_IO() when pushing aio+dio 256K reads at
~340MB/s.
So the resulting intent of the patch isn't a performance gain but to
avoid exposing ourselves to the risk of finding another field like
.map_bh.b_state where we rely on zeroing but don't enforce it in the
code.

* Add ivb_list[] table for listening early UDMA66 devices which don't conform

detection may be unreliable.

Configuring the OLPC camera requires something over 150 register
writes. Unfortunately, querying the CAFE i2c controller too
soon after a write causes the hardware to flake. The problem had
been "solved" with an msleep() call, but, between the number of
registers and how msleep() behaves, that resulted in a 3-second
delay on camera initialization. Instead, we hand-code a wait for
the completion interrupt which avoids reading the status registers.
