With kexec-based kernel boot loader on Zaurus, the machine ID is
actually correctly passed, and head-sharpsl.S is not necessary.
Introduce PXA_SHARPSL_DETECT_MACH_ID, and include head-sharpsl.S
only when that's explicitly enabled.

With a correct dev->dma_mask before calling dmabounce_register_dev(),
dma_needs_bounce() is not necessary.
The sa1111, though, is a bit complicated. Until it's fully understood
and fixed, dma_needs_bounce() for sa1111 is kept if CONFIG_SA1111 is
enabled with no side effect (with the condition of machine_is_*)
Thanks for Mike Rapoport to fix one error in the original version of
the patch and get this tested.

Not tested and enabled on MMP at this moment, and since the IRQ
is different from mach-pxa, I'd prefer to move the PMU device
back into mach-pxa/. Will introduce the PMU device to MMP once
it's enabled and tested.

Since commit a48c24a696f0d93c49f913b7818e9819612b1f4e, the
camera is not working anymore.
After the v4l2 migration, the mt9m111 camera board
information was not passed to the i2c layer anymore, but
stored for future use of v4l2 (through soc_camera).
Because mioa701_i2c_devices[] was tagged as "__initdata",
and because after the v4l2 migration, the new structure
"iclink" references it, the mt9m111 driver is not probed
anymore, as part of "iclink" is not valid (discarded after
kernel init).
Although there is not compilation error, nor runtime oops,
this patch restores a working camera on the mioa701 board.

|
|
Yannick found that video does not work with 2.6.34. The cause of this
bug was that the BIOS had assigned the wrong range to the PCI bridge
above the video device. Before 2.6.34 the kernel would have shrunk
the size of the bridge window, but since
d65245c PCI: don't shrink bridge resources
the kernel will avoid shrinking BIOS ranges.
So zero out the old range if we fail to claim it at boot time; this will
cause us to allocate a new range at startup, restoring the 2.6.34
behavior.
Fixes regression https://bugzilla.kernel.org/show_bug.cgi?id=16009.

Reinstate the null behaviour that the in-kernel gdbstub had for the GDB
remote protocol 'p' command (retrieve a single register value) prior to
commit 7ca8b9c0dafd ("frv: extend gdbstub to support more features of
gdb").
Before that, the 'p' command just returned an empty reply, which causes
gdb to then go and use the 'g' command. However, since that commit, the
'p' command returns an error string, which causes gdb to abort its
connection to the target.
Not all gdb versions are affected, some use try 'g' first, and if that
works, don't bother with 'p', and so don't see the error.

If cr0.wp=0, we have to allow the guest kernel access to a page with pte.w=0.
We do that by setting spte.w=1, since the host cr0.wp must remain set so the
host can write protect pages. Once we allow write access, we must remove
user access otherwise we mistakenly allow the user to write the page.

Always invalidate spte and flush TLBs when changing page size, to make
sure different sized translations for the same address are never cached
in a CPU's TLB.
Currently the only case where this occurs is when a non-leaf spte pointer is
overwritten by a leaf, large spte entry. This can happen after dirty
logging is disabled on a memslot, for example.

The commit "asm-generic: add NEED_SG_DMA_LENGTH to define sg_dma_len()"
18e98307de0d746cb0845ebf66535ce2184c25a2 broke microblaze compilation.
dma_direct_map_sg() sets sg->dma_length, however microblaze doesn't
set NEED_SG_DMA_LENGTH so scatterlist strcutres doesn't include
dma_length.
sg->dma_length is always equal to sg->length on microblaze. So we
don't need to set set dma_length, that is, microblaze can simply use
sg->length.

When functions incoming parameters are not in input operands list gcc
4.5 does not load the parameters into registers before calling this
function but the inline assembly assumes valid addresses inside this
function. This breaks the code because r0 and r1 are invalid when
execution enters v4wb_copy_user_page ()
Also the constant needs to be used as third input operand so account
for that as well.
Tested on qemu arm.
