f5020384e4 powerpc/xsysace: add compatible string for non-ipcore instance
Add "xlnx,sysace" compatible string to the of_platform binding
table.  Platforms which have the SysACE chip on board (e.g.
Katmai) instead of via a Xilinx generated IP core will use
this value in their device tree.

c14464bf79 xsysace: Fix driver to use resource_size_t instead of unsigned long
This patch is a bug fix to the SystemACE driver to use resource_size_t
for physical address instead of unsigned long.  This makes the driver
work correctly on 32 bit systems with 64-bit resources (e.g. PowerPC 440).

a108096878 powerpc/virtex: fix various format/casting printk mismatches
Various printk format string in code used by the Xilinx Virtex platform
are not 32-bit/64-bit safe.  Add correct casting to fix the bugs.

d4430d62fa [PATCH] beginning of methods conversion
To keep the size of changesets sane we split the switch by drivers;
to keep the damn thing bisectable we do the following:
	1) rename the affected methods, add ones with correct
prototypes, make (few) callers handle both.  That's this changeset.
	2) for each driver convert to new methods.  *ALL* drivers
are converted in this series.
	3) kill the old (renamed) methods.

Note that it _is_ a flagday; all in-tree drivers are converted and by the
end of this series no trace of old methods remain.  The only reason why
we do that this way is to keep the damn thing bisectable and allow per-driver
debugging if anything goes wrong.

New methods:
	open(bdev, mode)
	release(disk, mode)
	ioctl(bdev, mode, cmd, arg)		/* Called without BKL */
	compat_ioctl(bdev, mode, cmd, arg)
	locked_ioctl(bdev, mode, cmd, arg)	/* Called with BKL, legacy */

0e349b0e2d [POWERPC] Xilinx: Update compatible to use values generated by BSP generator.
Mainly, this involves two changes:
1) xilinx->xlnx (recognized standard is to use the stock ticker)
2) In order to have the device tree focus on describing what the
hardware is as exactly as possible, the compatible strings contain the
full IP name and IP version.

9bf722598f xsysace: end request handling fix
In ace_fsm_dostate(), the variable 'i' was used only for passing
sector size of the request to end_that_request_first().
So I removed it and changed the code to pass the size in bytes
directly to __blk_end_request()

a65b58663d blk_end_request: changing xsysace (take 4)
This patch converts xsysace to use blk_end_request interfaces.
Related 'uptodate' arguments are converted to 'error'.

xsysace is a little bit different from "normal" drivers.
xsysace driver has a state machine in it.
It calls end_that_request_first() and end_that_request_last()
from different states. (ACE_FSM_STATE_REQ_TRANSFER and
ACE_FSM_STATE_REQ_COMPLETE, respectively.)

However, those states are consecutive and without any interruption
inbetween.
So we can just follow the standard conversion rule (b) mentioned in
the patch subject "[PATCH 01/30] blk_end_request: add new request
completion interface".

d2bbf3da37 Sysace: Don't enable IRQ until after interrupt handler is registered
The previous patch to move the interrupt handler registration moved it
below enabling interrupts which could be a problem if the device is on
a shared interrupt line.  This patch fixes the order.
