Pull system.h fixups for less common arch's from Paul Gortmaker:
 "Here is what is hopefully the last of the system.h related fixups.

  The fixes for Alpha and ia64 are code relocations consistent with what
  was done for the more mainstream architectures.  Note that the
  diffstat lines removed vs lines added are not the same since I've
  fixed some of the whitespace issues in the relocated code blocks.
  However they are functionally the same.  Compile tested locally, plus
  these two have been in linux-next for a while.

  There is also a trivial one line system.h related fix for the Tilera
  arch from Chris Metcalf to fix an implict include.."

e1000e: issues in Sx on 82577/8/9

A workaround was previously put in the driver to reset the device when
transitioning to Sx in order to activate the changed settings of the PHY
OEM bits (Low Power Link Up, or LPLU, and GbE disable configuration) for
82577/8/9 devices.  After further review, it was found such a reset can
cause the 82579 to confuse which version of 82579 it actually is and broke
LPLU on all 82577/8/9 devices.  The workaround during an S0->Sx transition
on 82579 (instead of resetting the PHY) is to restart auto-negotiation
after the OEM bits are configured; the restart of auto-negotiation
activates the new OEM bits as does the reset.  With 82577/8, the reset is
changed to a generic reset which fixes the LPLU bits getting set wrong.

do not export kernel's NULL #define to userspace

GCC's NULL is actually __null, which allows detecting some questionable
NULL usage and warn about it.  Moreover each platform/compiler should
have its own stddef.h anyway (which is different from linux/stddef.h).

So there's no good reason to leak kernel's NULL to userspace and
override what the compiler provides.

perf tools: Fix parsers' rules to dependencies

Currently the parsers objects (bison/flex related) are each time perf
is built. No matter the generated files are already in place, the
parser generation is executed every time.

Changing the rules to have proper flex/bison objects generation
dependencies.

The parsers code is not rebuilt until the flex/bison source files
are touched. Also when flex/bison source is changed, only dependent
objects are rebuilt.

perf archive: Correct cutting of symbolic link

If a '$PERF_BUILDID_DIR'(typically $HOME/.debug) is a symbolic link
directory, cutting of the path will fail.

Here is an example where a buildid directory is a symbolic link.

/ # ls -al /root
lrwxrwxrwx    1 root     root            13 Mar 26  2012 /root -> opt/home/root
/ # cd ~
/opt/home/root # perf record -a -g sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.322 MB perf.data (~14057 samples) ]
/opt/home/root # perf archive
tar: Removing leading `/' from member names
Now please run:

$ tar xvf perf.data.tar.bz2 -C ~/.debug

wherever you need to run 'perf report' on.
/opt/home/root # mkdir temp
/opt/home/root # tar xf perf.data.tar.bz2 -C ./temp
/opt/home/root # find ./temp -name "*kernel*"
./temp/opt/home/root/.debug/[kernel.kallsyms]

-> If successfully cut off the path, [kernel.kallsyms] is located
in top of the archived file.

This patch enables to cut correctly even if the buildid directory
is a symbolic link.

net/ethernet: ks8851_mll fix rx frame buffer overflow

At the beginning of ks_rcv(), a for loop retrieves the
header information relevant to all the frames stored
in the mac's internal buffers. The number of pending
frames is stored as an 8 bits field in KS_RXFCTR.
If interrupts are disabled long enough to allow for more than
32 frames to accumulate in the MAC's internal buffers, a buffer
overflow occurs.
This patch fixes the problem by making the
driver's frame_head_info buffer big enough.
Well actually, since the chip appears to have 12K of
internal rx buffers and the shortest ethernet frame should
be 64 bytes long, maybe the limit could be set to
12*1024/64 = 192 frames, but 255 should be safer.

These were incorrectly introduced and can cause problems for of_irq_init.

The correct way to define a root controller is no interrupt-parent set at
all or the interrupt-parent is set to the root controller itself when
inherited from a parent node.
