* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc:
powerpc: Remove use of CONFIG_PPC_MERGE
powerpc: Force printing of 'total_memory' to unsigned long long
powerpc: Fix compiler warning in arch/powerpc/mm/mem.c
powerpc: Move include files to arch/powerpc/include/asm
* git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild-fixes:
kconfig: drop the ""trying to assign nonexistent symbol" warning
kconfig: always write out .config
My last change to tracehook.h made it confuse the kerneldoc parser.
Move the #define's before the comment so it's happy again.

Platforms that are using GENERIC_BUG must call in to
module_bug_finalize()/module_bug_cleanup() in order to scan modules with
their own __bug_table sections that are otherwise unaccounted.

Re: [PATCH] Fix the kernel panic of audit_filter_task when key field is set
The "user" parameter to __sched_setscheduler indicates whether the
change is being done on behalf of a user process or not. If not, we
shouldn't apply any permissions checks, so don't call
security_task_setscheduler().

2.6.26 corrected the mutex locking on tty resizing to fix the case where
you could get the tty/vt sizing out of sync. That turns out to have a
deadlock.
The actual fix is really major and I've got it lined up as part of the ops
changes for 2.6.28 so for 2.6.26/2.6.27 it is safer to reintroduce this
ages old minor bug.

Blackfin peers into the ldisc in an odd way for IRDA snooping which
therefore got missed. Simple enough fix.

snd_seq_oss_synth_make_info() incorrectly reports information
to userspace without first checking for the validity of the
device number, leading to possible information leak (CVE-2008-3272).

Please find the below testcase provide to test mlock.
Test Case :
===========================
#include <sys/resource.h>
#include <stdio.h>
#include <sys/stat.h>
#include <sys/types.h>
#include <unistd.h>
#include <sys/mman.h>
#include <fcntl.h>
#include <errno.h>
#include <stdlib.h>
int main(void)
{
int fd,ret, i = 0;
char *addr, *addr1 = NULL;
unsigned int page_size;
struct rlimit rlim;
if (0 != geteuid())
{
printf("Execute this pgm as root\n");
exit(1);
}
/* create a file */
if ((fd = open("mmap_test.c",O_RDWR|O_CREAT,0755)) == -1)
{
printf("cant create test file\n");
exit(1);
}
page_size = sysconf(_SC_PAGE_SIZE);
/* set the MEMLOCK limit */
rlim.rlim_cur = 2000;
rlim.rlim_max = 2000;
if ((ret = setrlimit(RLIMIT_MEMLOCK,&rlim)) != 0)
{
printf("Cant change limit values\n");
exit(1);
}
addr = 0;
while (1)
{
/* map a page into memory each time*/
if ((addr = (char *) mmap(addr,page_size, PROT_READ |
PROT_WRITE,MAP_SHARED,fd,0)) == MAP_FAILED)
{
printf("cant do mmap on file\n");
exit(1);
}
if (0 == i)
addr1 = addr;
i++;
errno = 0;
/* lock the mapped memory pagewise*/
if ((ret = mlock((char *)addr, 1500)) == -1)
{
printf("errno value is %d\n", errno);
printf("cant lock maped region\n");
exit(1);
}
addr = addr + page_size;
}
}
======================================================
This testcase results in an mlock() failure with errno 14 that is EFAULT,
but it has nowhere been specified that mlock() will return EFAULT. When I
tested the same on older kernels like 2.6.18, I got the correct result i.e
errno 12 (ENOMEM).
I think in source code mlock(2), setting errno ENOMEM has been missed in
do_mlock() , on mlock_fixup() failure.
SUSv3 requires the following behavior frmo mlock(2).
[ENOMEM]
Some or all of the address range specified by the addr and
len arguments does not correspond to valid mapped pages
in the address space of the process.
[EAGAIN]
Some or all of the memory identified by the operation could not
be locked when the call was made.
This rule isn't so nice and slighly strange. but many people think
POSIX/SUS compliance is important.
