Original patch from Marek Vasut, the problems with PXA26x are:
1. there are additional 4 GPIOs 86,87,88,89 have their direction bits
inverted in GPDR2, as well as their alternate function bits being
'1' for their GPIO functionality in GAFRx
2. there is no easy way to decide if the processor is a pxa26x or a
pxa250/pxa255 at run-time, so the assumption here is the pxa26x
will be treated as one of the pxa25x variants, and board code
should have a better knowledge of the processor it is featured
Introduce pxa26x_init_irq() for the second purpose, and treat the
additional GPIOs > 85 on PXA25x specially.
Kconfig option CONFIG_CPU_PXA26x is introduced to optimize the code
a bit when PXA26x support isn't needed. Board config options have
to select this to enable the support for PXA26x.
__gpio_is_inverted() will be optimized way when CONFIG_CPU_PXA26x
isn't selected.

The 32-bit xfs_blkstat_one handler was failing because
a size check checked whether the remaining (32-bit)
user buffer was less than the (64-bit) bulkstat buffer,
and failed with ENOMEM if so. Move this check
into the respective handlers so that they check the
correct sizes.
Also, the formatters were returning negative errors
or positive bytes copied; this was odd in the positive
error value world of xfs, and handled wrong by at least
some of the callers, which treated the bytes returned
as an error value. Move the bytes-used assignment

Currently the compat formatter was handled by passing
in "private_data" for the xfs_bulkstat_one formatter,
which was really just another formatter... IMHO this
got confusing.
Instead, just make a new xfs_bulkstat_one_compat
formatter for xfs_bulkstat, and call it via a wrapper.
Also, don't translate the ioctl nrs into their native
counterparts, that just clouds the issue; we're in a
compat handler anyway, just switch on the 32-bit cmds.

Create a new xfs_ioctl.h file which has prototypes for

Change several compat ioctl cases which are IOW to simply copy
in the userspace argument, then call the common ioctl helper.
This also fixes xfs_compat_ioc_fsgeometry_v1(), which had
it backwards before; it copied in an (empty) arg, then copied
out the native result, which probably corrupted userspace. It
should be translating on the copyout.

Fix module removal bugs of i82875p_edac. Also i82975x_edac code seems to
have the same module removal bugs as in i82875p_edac.
The problems were:
1. In module removal i82875p_remove_one() is never called.
Variable i82875p_registered is newer changed from 1, which
guarantees i82875p_remove_one() is not called (and even if it were
called, it would be called in wrong order).
As a result, the edac_mc workque is not stopped and keeps probing.
If kernel debugging options are not enabled, user may not notice
anything going wrong.
if debugging options are enabled and I do "rmmod i82875p_edac", I
get:
edac debug: edac_pci_workq_function() checking
BUG: unable to handle kernel paging request at f882d16f
...
call trace:

[<c0204587>] ? kernel_thread_helper+0x7/0x10
Fix for this is to get rid of needles variable i82875p_registered
altogether and run i82875p_remove_one() *before*
pci_unregister_driver().
2. edac_mc_del_mc() uses mci after freeing mci
edac_mc_del_mc() calls calls edac_remove_sysfs_mci_device(). The
kobject refcount of mci drops to 0 and mci is freed. After this
mci is accessed via debug print and i82875p_remove_one() still
uses mci->pvt and tries to free mci again with edac_mc_free().
The fix for this is add kobject_get(&mci->edac_mci_kobj) after
edac_mc_alloc(). Then the mci is still available after returning
from edac_mc_del_mc() with refcount 1, and mci->pvt is still
available. When i82875p_remove_one() finally calls edac_mc_free(),
this will cause kobject_put() and mci is released properly.

The overflow device on the MB seems to be hidden and its resources are not

I am again able to load and use the module.

The commit aef7db4bd5 fixed the problem with
recursive locking in fb blanking code if blank is caused by user setting
the /sys/class/graphics/fb*/blank. However this broke the fbcon timeout
blanking.
If you use a driver that defines ->fb_blank operation and at the same time
that driver relies on other driver (e.g. backlight or lcd class) to blank
the screen, when the fbcon times out and tries to blank the fb, it will
call only fb driver blanker and won't notify the other driver. Thus FB
output is disabled, but the screen isn't blanked.
Restore fbcon blanking and at the same time apply the proper fix for the
above problem: if fbcon_blank is called with FBINFO_FLAG_USEREVENT, we are
already called through notification from fb_blank, thus we don't have to
blank the fb again.
