kprobe_ftrace_handler must take care for that.

Hi Greg,
Today's linux-next merge of the staging tree got a conflict in
drivers/staging/ipack/devices/ipoctal.c between commit 734cc1783816
("TTY: use tty_port_register_device") from the tty tree and commit
2afb41d9d30d ("Staging: ipack/devices/ipoctal: Check tty_register_device
return value")
When I offline a memory on linux-3.6-rc5, "possible circular
locking dependency detected" messages are shown.
Are the messages known problem?

Replace the current (inefficient) for-loop with memcpy, to copy priomap.

The update_netdev_tables() function appears to be unnecessary, since the
write_update_netdev_table() function will adjust the priomaps as and when
required anyway. So drop the usage of update_netdev_tables() entirely.

Hi all,
Today's linux-next merge of the arm-soc tree got a conflict in
drivers/i2c/busses/i2c-omap.c between commit d9ebd04d3476 ("i2c: omap:
switch to devm_* API") from the i2c-embedded tree and commit 07baca6f8fc2
("i2c/i2c-omap: add a const qualifier") from the arm-soc tree.
I fixed it up

While generally true, for the DT specific code I think it should be a
fixed u64. The size of the address is defined by the FDT, not the
kernel. It is very likely we could have

In some cases mmc_suspend_host() is not able to claim the
host and proceed with the suspend process. The core returns
-EBUSY to the host controller driver. Unfortunately, the
host controller driver does not pass on this information
to the PM core and hence the system suspend
