Be aware that at the moment many callers of gpiochip_remove() read its

Variable "rt_rq" is used only in block "for_each_sched_rt_entity" so the
value assigned to it at the beginning of the update_curr_rt(...) gets
overwritten without ever being read. Remove redundant assignment and
move variable declaration to the block in which it is being used.

Now that the irq work subsystem can queue remote callbacks, it's
a perfect fit to safely queue IPIs when interrupts are disabled
without worrying about concurrent callers.
Lets use it for the full dynticks kick to notify a CPU that it's

This unbloats a bit the scheduler
This version implements separate lists for tick and IPI works. As such
it simplifies the IPI raise decision.

An irq work can be handled from two places: from the tick if the work

We merge all these works in a single list and we use some per cpu latch

The actual Linux implementation for semctl(GETNCNT) and semctl(GETZCNT)
always (since 0.99.10) reported a thread as sleeping on all semaphores
that are listed in the semop() call.
The documented behavior (both in the Linux man page and in the Single Unix
Specification) is that a task should be repo

Which outputs?
If it's the PLLx2, PLLx4 and PLLx8, like I said, use fixed factor
clocks.

No, it should be part of the AHB1 clock code

Tried yesterdays git v3.15-rc6-190-g1ee1cea on Sun Fire T2000 (32-thread
sparc64) and got reproducibly stuck on boot with ext journal replay like
below. Booting Debian 3.14.2-1 replayed the log and mounted FS fine.
After that, my test kernel works fine too. SO I can not reproduce it any

MOV CR/DR instructions ignore the mod field (in the ModR/M byte). As the SDM
states: "The 2 bits in the mod field are ignored". Accordingly, the second
operand of these instructions is always a general purpose register.
The current emulator implementation does not do so. If the mod bits do not

Hi Nadia,
You added a patch that adds dynamic scaling of MSGMNI (f7bf3df8).
The description begins with:
On large systems we'd like to allow a larger number of message queues. In
some cases up to 32K. However simply setting MSGMNI to a larger value may
cause problems for smaller systems.

Add missing specification of efm32_uart_exit as module_exit.
This fixes the following compilation warning:
drivers/tty/serial/efm32-uart.c:840:123: warning: ‘efm32_uart_exit’ defined
but not used [-Wunused-function]
