2012-07-31mac80211: move TX station pointer and restructure TXThomas Huehn
Remove the control.sta pointer from ieee80211_tx_info to free up sufficient space in the TX skb control buffer for the upcoming Transmit Power Control (TPC). Instead, the pointer is now on the stack in a new control struct that is passed as a function parameter to the drivers' tx method.

2012-07-26pch_uart: Add eg20t_port lock field, avoid recursive spinlocksDarren Hart
pch_uart_interrupt() takes priv->port.lock which leads to two recursive spinlock calls if low_latency==1 or CONFIG_PREEMPT_RT_FULL=y (one otherwise): pch_uart_interrupt spin_lock_irqsave(priv->port.lock, flags) case PCH_UART_IID_RDR_TO (data ready) handle_rx_to push_rx tty_port_tty_get spin_lock_irqsave(&port->lock, flags) <--- already hold this lock ... tty_flip_buffer_push ... flush_to_ldisc spin_lock_irqsave(&tty->buf.lock) spin_lock_irqsave(&tty->buf.lock) disc->ops->receive_buf(tty, char_buf) n_tty_receive_buf tty->ops->flush_chars() uart_flush_chars uart_start spin_lock_irqsave(&port->lock) <--- already hold this lock Avoid this by using a dedicated lock to protect the eg20t_port structure and IO access to its membase. This is more consistent with the 8250 driver. Ensure priv->lock is always take prior to priv->port.lock when taken at the same time. V2: Remove inadvertent whitespace change. V3: Account for oops_in_progress for the private lock in pch_console_write(). Note: Like the 8250 driver, if a printk is introduced anywhere inside the pch_console_write() critical section, the kernel will hang on a recursive spinlock on the private lock. The oops case is handled by using a trylock in the oops_in_progress case.

pm_restore_console() is called from the suspend/resume path, and this calls vt_move_to_console(), which calls vt_waitactive().

2012-07-26bcma: fix invalid PMU chip control masksHauke Mehrtens
Commit b9562545ef0b ("bcma: complete workaround for BCMA43224 and BCM4313") introduced the wrong masks for setting the chip control registers - the "mask" parameter is inverse. It should be the mask of bits *not* changed, which is admittedly a bit non-intuitive. The incorrect mask not only causes the driver to not work correctly on the chips affected (eg the BCM43224 on the Macbook Air 4,2) but the state persists over a soft reset, causing the next boot to not necessarily see the device correctly.

2012-07-26bcma: fix regression in interrupt assignment on mipsHauke Mehrtens
The wrong interrupts where assigned to the cores in bcma_core_mips_init(). This caused at least my serial console not to response to any input. This was caused by this patch which changed the order of the cores in the list: commit c334e25c9f3a95f2bd6b79fedc5170f17245b1c7 Author: Rafał Miłecki <zajec5@gmail.com> Date: Wed Jul 11 12:37:00 2012 +0200 bcma: add new cores at the end of list This should be fixed properly later so that the correct interrupt numbers are assigned to the cores independently from the ordering of the list. This patch restores the old behavior again. I will look into the problem more deeply later. I also changed the order of the list with the cores and their assigned interrupt number which gets printed to the log. Now they are printed in the same order like all the other lists of cores and like it was done before the patch which changed the order.
