0c6856f702 [PATCH] oprofile: Fix unnecessary cleverness
nmi_create_files() in arch/i386/oprofile/nmi_int.c depends on
model->num_counters (number of performance counters) being less than 10.
While this is currently the case, it's too clever by half.

Other archs aren't quite as clever: they assume 100.  I suggest to
normalize them all to 1000.

726c334223 [PATCH] VFS: Permit filesystem to perform statfs with a known root dentry
Give the statfs superblock operation a dentry pointer rather than a superblock
pointer.

This complements the get_sb() patch.  That reduced the significance of
sb->s_root, allowing NFS to place a fake root there.  However, NFS does
require a dentry to use as a target for the statfs operation.  This permits
the root in the vfsmount to be used instead.

linux/mount.h has been added where necessary to make allyesconfig build
successfully.

Interest has also been expressed for use with the FUSE and XFS filesystems.

Historically plat_mem_setup did the entire platform initialization.  This
was rather impractical because it meant plat_mem_setup had to get away
without any kind of memory allocator.  To keep old code from breaking
plat_setup was just renamed to plat_setup and a second platform
initialization hook for anything else was introduced.

e1701fb2e2 [PATCH] Fix BCM1480 doubled process accounting times.
Running a UP kernel on a bcm1480 board, I get nonsensical timing
results, like this:
release@unknown:~/tmp$ time ./a.out
real    0m22.906s
user    0m45.792s
sys     0m0.010s
According to my watch, this program took 23 seconds to run, so the real
time clock is OK.  It is process accounting that is broken.

I tracked this down to a problem with the function
bcm1480_timer_interrupt in the file sibyte/bcm1480/time.c.  This
function calls ll_timer_interrupt for cpu0, and ll_local_timer_interrupt
for all cpus.  However, both of these functions do process accounting.
Thus processes running on cpu0 end up with doubled times.  This is very
obvious in a UP kernel where all processes run on cpu0.

The correct way to do this is to only call ll_local_timer interrupt if
this is not cpu0.  This can be seen in the mips-board/generic/time.c
file, and also in the sibyte/sb1250/time.c file, both of which handle
this correctly.  I fixed the bcm1480/time.c file by copying over the
correct code from the sb1250/time.c file.

With this fix, I now get sensible results.
release@unknown:~/tmp$ time ./a.out
real    0m22.903s
user    0m22.894s
sys     0m0.006s
