IXP4xx: Extend PCI MMIO indirect address space to 1 GB.
IXP4xx: Fix compilation failure with CONFIG_IXP4XX_INDIRECT_PCI.
IXP4xx: Drop "__ixp4xx_" prefix from in/out/ioread/iowrite functions for clarity.
IXP4xx: Rename indirect MMIO primitives from __ixp4xx_* to __indirect_*.
IXP4xx: Ensure index is positive in irq_to_gpio() and npe_request().
ARM: fix insl() and outsl() endianness on IXP4xx architecture.
IXP4xx: Fix normally-disabled debugging text in drivers/net/arm/ixp4xx_eth.c.
IXP4xx: change the timer base frequency to 66.666000 MHz. -
The fasync path takes the BKL (it probably doesn't need to in fact)
while holding the file_list spinlock. You can't do that with the kernel
lock: it causes lock inversions and deadlocks.Leave the BKL over that bit for the moment.

This change makes it so that reset/interrupt storms can be avoided when
there are mailbox issues. The new behavior is to only allow the device to
trigger mailbox related resets only once every 10 seconds.Signed-off-by: Alexander Duyck

The tty count sanity check may need the BKL, that isn't clear. However it
is clear that the count use of the lock is internal and independant of the
bigger use of the lock.Furthermore the file list locking is also separately locked already

moxa_openlock is used for several situations where we want to handle the
case of an ioctl that crosses many ports (not just the open tty), and also
cases where an open races a deinit (eg a pci unplug) and we hangup a port
before we can cope with that.The non open race cases can use the moxa_lock spinlock. This simplifies sorting
out the remaining mess.Signed-off-by: Alan Cox

- The open lock is needed to fix up the case of a board reset occuring during

Alexander Strakh reported
KERNEL_VERSION: 2.6.31
DESCRIBE:
Driver drivers/char/isicom.c might sleep in atomic context, because it
calls
tty_port_xmit_buf under spin_lock../drivers/char/isicom.c:
1307 static void isicom_hangup(struct tty_struct *tty)
1308 {
...
1315 spin_lock_irqsave(&port->card->card_lock, flags);
1316 isicom_shutdown_port(port);
...Path to might_sleep macro from isicom_hangup:
1. isicom_hangup calls spin_lock_irqsave (drivers/char/isicom.c:1315) and
then
calls isicom_shutdown_port.
2. isiscom_shutdown_port calls tty_port_free_xmit_buf at
drivers/char/isicom.c:906
3. tty_port_free_xmit_buf calls mutex_lock at drivers/char/tty_port:48Found by Linux Driver Verification Project.
