Hi all,
after upgrading one of my servers to 3.8, then 3.9.7 and 3.10-rc6, I started to
see lots of "Timed out waiting for forcewake old ack to clear" error messages,
including hang-ups especially if the system was highly loaded. With 3.5.24
everything was fine.
After backing out commit 36ec8f877

For the related next strcpy(), the destination length is less than 512,
but the source maximize length may be 'OPROMMAXPARAM' (4096) which is

One work flow may:

Returning a pointer to a variable in the setup_from_dt function is
causing dangling pointer dereferences. This causes boot to fail
on AM33XX.
Add ninfo to the caller's stack and just return the kzalloc'ed ptr
from the calling function.

In this patchset, we introduce two optimizations to read write semaphore.
The first one reduces cache bouncing of the sem->count field
by doing a pre-read of the sem->count and avoid cmpxchg if possible.

Doing cmpxchg will cause cache bouncing when checking
sem->count. This could cause scalability issue
in a large machine (e.g. a 80 cores box).
A pre-read of sem->count can mitigate this.

Manfred has a few ipc/sem.c patches in linux-next, starting at commit
c50df1b4 (ipc/sem.c: cacheline align the semaphore structures), does
reverting any of those instead of "ipc,msg: shorten critical region in
msgrcv" help at all? Also, anything reported in dmesg?

Add a new device tree enabled pinctrl driver for
Qualcomm MSM SoC's. This driver provides an extensible
framework to interface all MSM's that use a TLMM pinmux,
with the pinctrl subsytem.
This driver is split into two parts: the pinctrl interface
and the TLMM version specific implementation. The p
The pci-me.c code contains 2 dev_err() calls which are apparently left
over from debugging; they do not represent actual error conditions.
They do produce messages in a "quiet" kernel, and add ERROR entries to
the logger.

The delay functions that move memory to the absent list are __init
but the read back of the list and memory insertion are not. BTW, this

Unlike other OMAP4 platforms including the the "vanilla" PandaBoard,
PandaBoard-ES uses TPS62361 to supply vdd_mpu.
