There's really no reason not to print more than one character at a
time to the PDC console... Booting is measurably speedier, and now I don't
have to watch individual characters get drawn.Signed-off-by: Kyle McMartin

The timer interrupt had accidentally been marked IRQ_DISABLED since
IRQ_PER_CPU had been OR-ed in, instead of set. This had been working
by accident for quite a while.Commit c642b8391cf8efc3622cc97329a0f46e7cbb70b8 changed the behaviour of
IRQ_PER_CPU interrupts, which previously weren't checked for IRQ_DISABLED.Signed-off-by: Kyle McMartin

This reverts commit efb80e7e097d0888e59fbbe4ded2ac5a256f556d, it turned
out to cause sporadic problems with the timer interrupt on 32-bit kernels.
Needs more investigation.Signed-off-by: Kyle McMartin

Quoting Randy:
"It seems sad that this patch sources Kconfig.marker, a 7-line file,
20-something times. Yes, you (we) don't want to put those 7 lines into
20-something different files, so sourcing is the right thing.However, what you did for avr32 seems more on the right track to me: make
_one_ Instrumentation support menu that includes PROFILING, OPROFILE, KPROBES,
and MARKERS and then use (source) that in all of the arches."Signed-off-by: Mathieu Desnoyers

This is the largest patch in the set. Make all (I hope) the places where
the pid is shown to or get from user operate on the virtual pids.The idea is:
- all in-kernel data structures must store either struct pid itself
or the pid's global nr, obtained with pid_nr() call;
- when seeking the task from kernel code with the stored id one
should use find_task_by_pid() call that works with global pids;
- when showing pid's numerical value to the user the virtual one
should be used, but however when one shows task's pid outside this
task's namespace the global one is to be used;
- when getting the pid from userspace one need to consider this as
the virtual one and use appropriate task/pid-searching functions.[akpm@linux-foundation.org: build fix]

pcibios_link_hba_resources() could corrupt the resource tree by inserting
resources in the wrong place. Fix this by calling pci_claim_resource()
for PCI-PCI bridges. Delete pcibios_link_hba_resources as we shouldn't
need it any more. Also get rid of lba_claim_dev_resources() and just
call pci_claim_resource() directly.Signed-off-by: Matthew Wilcox

We have had complaints where a threaded application is left in a bad state
after one of it's threads is killed when we hit a VM: out_of_memory
condition.Killing just one of the process threads can leave the application in a bad
state, whereas killing the entire process group would allow for the
application to restart, or be otherwise handled, and makes it very obvious
that something has gone wrong.This change allows the entire process group to be taken down, rather
than just the one thread.Signed-off-by: Will Schmidt

The variable CFLAGS is a wellknown variable and the usage by
kbuild may result in unexpected behaviour.
On top of that several people over time has asked for a way to
pass in additional flags to gcc.This patch replace use of CFLAGS with KBUILD_CFLAGS all over the
tree and enabling one to use:
make CFLAGS=...
to specify additional gcc commandline options.One usecase is when trying to find gcc bugs but other
use cases has been requested too.Patch was tested on following architectures:
alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68kTest was simple to do a defconfig build, apply the patch and check
that nothing got rebuild.Signed-off-by: Sam Ravnborg

Remove fs.h from mm.h. For this,
1) Uninline vma_wants_writenotify(). It's pretty huge anyway.
2) Add back fs.h or less bloated headers (err.h) to files that need it.As result, on x86_64 allyesconfig, fs.h dependencies cut down from 3929 files
rebuilt down to 3444 (-12.3%).Cross-compile tested without regressions on my two usual configs and (sigh):

per cpu data section contains two types of data. One set which is
exclusively accessed by the local cpu and the other set which is per cpu,
but also shared by remote cpus. In the current kernel, these two sets are
not clearely separated out. This can potentially cause the same data
cacheline shared between the two sets of data, which will result in
unnecessary bouncing of the cacheline between cpus.One way to fix the problem is to cacheline align the remotely accessed per
cpu data, both at the beginning and at the end. Because of the padding at
both ends, this will likely cause some memory wastage and also the
interface to achieve this is not clean.This patch:
Moves the remotely accessed per cpu data (which is currently marked
as ____cacheline_aligned_in_smp) into a different section, where all the data
elements are cacheline aligned. And as such, this differentiates the local
only data and remotely accessed data cleanly.Signed-off-by: Fenghua Yu
