swiotlb_alloc_coherent calls panic() when allocated swiotlb pages is
not fit for a device's dma mask. However, alloc_coherent failure is
not a disaster at all. AFAIK, none of other x86 and IA64 IOMMU
implementations don't crash in case of alloc_coherent failure.
There are some drivers that don't check alloc_coherent failure but not
many (about ten and I've already started to fix some of
them). alloc_coherent returns NULL in case of failure so it's likely
that these guilty drivers crash immediately. So swiotlb doesn't need
to call panic() just for them.

clean up of xencomm.c. is_phys_contiguous() is arch dependent
function that depends on how virtual memory are laid out.
So split out the function into arch specific code.

Impact: cleanup, small kernel text size reduction, no functionality changed
reserve_region_with_split() calls in to __reserve_region_with_split(),
which is an __init function. The only caller of reserve_region_with_split()
is an __init function, so make it __init too.

Move free_module_param_attrs() into the CONFIG_MODULES section, since
it's only used inside there. Thus avoiding the warning

Commit 4752c369789250eafcd7813e11c8fb689235b0d2 aka
"maps4: simplify interdependence of maps and smaps" broke /proc/pid/smaps,
causing it to display some vmas twice and other vmas not at all. For example:
grep .- /proc/1/smaps >/tmp/smaps; diff /proc/1/maps /tmp/smaps
1 25d24
2 < 7fd7e23aa000-7fd7e23ac000 rw-p 7fd7e23aa000 00:00 0
3 28a28
4 > ffffffffff600000-ffffffffff601000 r-xp 00000000 00:00 0 [vsyscall]
The bug has something to do with setting m->version before all the
seq_printf's have been performed. show_map was doing this correctly,
but show_smap was doing this in the middle of its seq_printf sequence.
This patch arranges things so that the setting of m->version in show_smap
is also done at the end of its seq_printf sequence.
Testing: in addition to the above grep test, for each process I summed
up the 'Rss' fields of /proc/pid/smaps and compared that to the 'VmRSS'
field of /proc/pid/status. All matched except for Xorg (which has a
/dev/mem mapping which Rss accounts for but VmRSS does not). This result
gives us some confidence that neither /proc/pid/maps nor /proc/pid/smaps
are any longer skipping or double-counting vmas.

This was another merge problem that wasn't a data conflict, but due to
independent changes in two branches that just didn't work together.
The pcc-acpi staging driver used
acpi_driver_data(device) = hotkey;
to set driver data, but the ACPI merge made that invalid in commit
db89b4f0dbab837d0f3de2c3e9427a8d5393afa3 ("ACPI: catch calls of
acpi_driver_data on pointer of wrong type"), and now you're supposed to
just do.
device->driver_data = hotkey;
instead.
Fix it up.

This one was due to a merge error: we added a use of nd.path in commit
2d7c820e56ce83b23daee9eb5343730fb309418e ("ext3: add checks for errors
from jbd"), and concurrently we got rid of 'nd' and used a naked 'path'
in commit 8264613def2e5c4f12bc3167713090fd172e6055 ("[PATCH] switch
quota_on-related stuff to kern_path()").
That all merged cleanly, but it didn't actually _work_. This should fix
it.
