The offset in the core file used to be tracked with ->written field of
the coredump_params structure. Commit a0083939510 ("get rid of
coredump_params->written") replaced all its uses with file->f_pos.
However, ->f_pos is not maintained for pipes which leads to breakage.

Hi Mark,
Fetching the c6x tree has produced this error for the past few days:

The subject for this patch has a misplaced "i" at the beginning courtesy of vi.
One other point, it is customary to start the patch
Straigntforward conversion from
int has_N44_O17_errata[NR_CPUS]
to
DECLARE_BITMAP(has_N44_O17_errata, NR_CPUS)
Saves about 2 kbytes in bss for NR_CPUS=512.

With both gcc 4.7.2 and 4.9.2, sometimes gcc mysteriously doesn't inline
very small functions we expect to be inlined. See
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66122
With this .config:
http://busybox.net/~vda/kernel_config_OPTIMIZE_INLINING_and_Os,
get_bh() gets deinlined 32 times, put
It used to be EXPORTed, but then EXPORT usage was cleaned up
(in 2012), without noticing that the function has no users at all
(and curiously, never had any users).
Delete it.
While at it, remove non-static "inline" hints on nearby functions:
these hints don't work across compilation units anyway
It looks like author of this code wasn't aware that plain "inline"
without "static" does emit an (unused in this case) function body.
Add "static" to every inline in drivers/media/platform/fsl-viu.c
viu_default_settings() has only one callsite, so remove "inline" from it.

Hi,
The main drawback of those patches is that they break the alignment
(checkpatch.pl --strict complains).
