broadsheetfb: support storing waveform
This patch adds waveform storing capability to broadsheetfb. It uses the
firmware class to retrieve the waveform, and the request to initiate the
waveform storing is done via a driver sysfs entry, loadstore_waveform.
Broadsheet is a framebuffer device. It is slightly different from a
typical framebuffer controller that drives a normal TFT-LCD display. Most
E-Ink display panels require a waveform in order to function. That is, in
order to drive the state of a pixel to black, gray, or white, a specific
waveform is utilized. Basically, that waveform represents the specific
E-field wiggling needed to get the pixel to its optimal state given
current temperature, and its previous state. TN/IPS-LCDs use a similar
concept but the driving waveform is sufficiently simple that it is
internalized in the TFT source/gate driver.
These E-Ink waveforms are specific to a production batch. That is, a
batch of display films are produced, then they get characterized and a
waveform is generated for that batch. Broadsheet, typically, is attached
to its private SPI flash which is then flashed with this waveform.
Users won't be able to see the waveform and typically won't ever need to
know about it. If however, the display panel attached to broadsheet is
changed out, then they will need to update their waveform. That would
typically be done at a factory or repair facility rather than by a user.

from a bug in writing multiple color registers at once. The removal of
viafb_setcmap might introduce a small performance regression but its
certainly better to receive the correct result a bit slower than a garbled
picture fast. It should give us a working 8bpp mode and is more
extensible than the old hardcoded code. No other regressions are expected

This patch is an attempt to make viafb_set_par work correctly with more

viafbinfo{,1} to ensure that each function is called with the correct

This patch (finally) allows usable dual framebuffer setups and should not
affect non dual fb ones. It works in some (most?) configurations as
sometimes the driver still gets device connections wrong. It can be worth
to try the devices in reverse order (in viafb_active_dev).
The user experience is still not very nice as:
- on the second fb you'll normally have a garbled picture as long as
no application draws to it
goal: auto on/off devices depending on reference counting
- as the whole machinery is always done you can see mode changes also
in an unaffected framebuffer

viafb: split global index up
This is the first step to remove an artificial global index that was used
in two ways:
1. As a pseudo index in the mode table. Pseudo as you had to search
through the table to find the referenced entry. This was replaced by
using a pointer to the entry.
2. As a shortcut to compare a combination of horizontal and vertical
resolution at the same time.
This was replaced by a "(hres<<16) | vres" which is good enough for
now and the near future. If vres or hres become greater than 2^16 this
might indeed cause problems but this solution allows to split this
indexing mess up without the requirement to do even more code changes.
This is a big change that will allow more clean ups. It should be a bit
faster but that is probably not relevant for normal operation. No
regressions expected but as this is a relatively big step heavy testing is
appreciated.

Add generic sys_ipc wrapper
Add a generic implementation of the ipc demultiplexer syscall. Except for
s390 and sparc64 all implementations of the sys_ipc are nearly identical.
There are slight differences in the types of the parameters, where mips
and powerpc as the only 64-bit architectures with sys_ipc use unsigned
long for the "third" argument as it gets casted to a pointer later, while
it traditionally is an "int" like most other paramters. frv goes even
further and uses unsigned long for all parameters execept for "ptr" which
is a pointer type everywhere. The change from int to unsigned long for
"third" and back to "int" for the others on frv should be fine due to the
in-register calling conventions for syscalls (we already had a similar
issue with the generic sys_ptrace), but I'd prefer to have the arch
maintainers looks over this in details.
Except for that h8300, m68k and m68knommu lack an impplementation of the
semtimedop sub call which this patch adds, and various architectures have
gets used - at least on i386 it seems superflous as the compat code on
x86-64 and ia64 doesn't even bother to implement it.

mm: do not iterate over NR_CPUS in __zone_pcp_update()
__zone_pcp_update() iterates over NR_CPUS instead of limiting the access
to the possible cpus. This might result in access to uninitialized areas
as the per cpu allocator only populates the per cpu memory for possible
cpus.
This problem was created as a result of the dynamic allocation of pagesets
from percpu memory that went in during the merge window - commit

Additionally, the CMD52 must be issued first because it cannot be issued

fs: buffer_head: remove kmem_cache constructor to reduce memory usage under slub
When using slub, having a kmem_cache constructor forces slub to add a free
pointer to the size of the cached object, which can have a significant
impact to the number of small objects that can fit into a slab.
As buffer_head is relatively small and we can have large numbers of them,
removing the constructor is a definite win.
On x86_64 removing the constructor gives me 39 objects/slab, 3 more than
without the patch. And on x86_32 73 objects/slab, which is 9 more.
As alloc_buffer_head() already initializes each new object there is very
little difference in actual code run.
