As noticed by Russell King, we were not setting this properly
to the number of entries, but rather the total size.This results in the core dumping code allocating waayyyy too
much memory.Signed-off-by: David S. Miller

When a device is under an EBUS or ISA bus, the resource flags
don't get set properly.Fix this by re-evaluating the resource flags at each level of
bus as we apply ranges on the way to the root. And let PCI
override any existing flags setting, but don't let the
default flags calculator make such overrides.Signed-off-by: David S. Miller

Correct sparc64's implementation of FUTEX_OP_ANDN to do a
bitwise negate of the oparg parameter before applying the
AND operation. All other archs that support FUTEX_OP_ANDN
either negate oparg explicitly (frv, ia64, mips, sh, x86),
or do so indirectly by using an and-not instruction (powerpc).
Since sparc64 has and-not, I chose to use that solution.I've not found any use of FUTEX_OP_ANDN in glibc so the
impact of this bug is probably minor. But other user-space
components may try to use it so it should still get fixed.Signed-off-by: Mikael Pettersson

Update include/asm/Kbuild so we export
all relvant headers for sparc.Signed-off-by: Sam Ravnborg
-
The majority of this patch was created by the following script:
***
ASM=arch/sparc/include/asm
mkdir -p $ASM
git mv include/asm-sparc64/ftrace.h $ASM
git rm include/asm-sparc64/*
git mv include/asm-sparc/* $ASM
sed -ie 's/asm-sparc64/asm/g' $ASM/*
sed -ie 's/asm-sparc/asm/g' $ASM/*
***The rest was an update of the top-level Makefile to use sparc
for header files when sparc64 is being build.
And a small fixlet to pick up the correct unistd.h from
sparc64 code.Signed-off-by: Sam Ravnborg

This patch introduces the new syscall pipe2 which is like pipe but it also
takes an additional parameter which takes a flag value. This patch implements
the handling of O_CLOEXEC for the flag. I did not add support for the new
syscall for the architectures which have a special sys_pipe implementation. I
think the maintainers of those archs have the chance to go with the unified
implementation but that's up to them.The implementation introduces do_pipe_flags. I did that instead of changing
all callers of do_pipe because some of the callers are written in assembler.
I would probably screw up changing the assembly code. To avoid breaking code
do_pipe is now a small wrapper around do_pipe_flags. Once all callers are
changed over to do_pipe_flags the old do_pipe function can be removed.The following test must be adjusted for architectures other than x86 and
x86-64 and in case the syscall numbers changed.~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

free_area_init_node() gets passed in the node id as well as the node
descriptor. This is redundant as the function can trivially get the node
descriptor itself by means of NODE_DATA() and the node's id.I checked all the users and NODE_DATA() seems to be usable everywhere
from where this function is called.Signed-off-by: Johannes Weiner
