The request for an IRQ handler must be done after whole configuration. This

In some conditions (echo or particular sequence of special
characters), on buffer push, the tty layer calls the write operation
while we are holding the spinlock. This means deadlock within the same
process on kernels version < 3.12. It seems not a problem on recent
kernel, but the patch still valid as locking optimization.

The protected variables by the spinlock are: xmit_buf, nb_bytes,
pointer_read and pointer_write. So, this patch reduces the locked area
in the IRQ handler only to these variables. Most of the code inside the
locked area in the IRQ handler is not protected elsewhere; it means
that it is not protected at all.

commit dabd1468 "PCMCIA: sa1111: remove duplicated initializers"
incorrectly moved some code into the pcmcia_jornada720_init, causing
a few build errors, and for unknown reasons, the driver lacks
an inclusion of <linux/io.h>, so we get the build errors, and more:

The lubbock platform uses the sa1111 companion chip with a pxa250
CPU, which means it requires both the PCMCIA_SA1111 and the
PCMCIA_PXA2XX code to be built into the kernel. Unfortunately,
the Makefile and Kconfig don't agree on how this is accomplished,
leading to a situation where you get this link error when building
a lubbock kernel with PCMCIA_SA1111 enabled but PCMCIA_PXA2XX
disabled:

ERROR: "pxa2xx_configure_sockets" [drivers/pcmcia/sa1111_cs.ko] undefined!

GenWQE used to call pci_enable_msi_block to allocate a desired number
of MSI's. If that was not possible pci_enable_msi_block returned with a
smaller number which might be possible to allocate. GenWQE then called
pci_enable_msi_block with that number.

Since commit a30d0108
"GenWQE: Use pci_enable_msi_exact() instead of pci_enable_msi_block()"
pci_enable_msi_exact is used which fails if the desired number of MSI's
was not possible to allocate. Change GenWQE to use pci_enable_msi_range
to restore the old behavior.

Currently, in the event of a fatal hardware error, the driver tries a
recovery procedure that calls pci_reset_function() to reset the card.
This is not sufficient in some cases, needing a fundamental reset to
bring the card back.

This patch implements a call to the platform fundamental reset procedure
on the error recovery path if GENWQE_PLATFORM_ERROR_RECOVERY is enabled.
This is implemented by default only on PPC64, since this can cause
problems on other archs, e.g. zSeries, where the platform has its own
recovery procedures, leading to a potencial race conditition. For these
cases, the recovery is kept as it was before.

This patch implements the callbacks and functions necessary to have EEH
recovery support.

It adds a config option to enable or disable explicit calls to trigger
platform specific mechanisms on error recovery paths. This option is
enabled by default only on PPC64 systems and can be overritten via
debugfs. If this option is enabled, on the error recovery path the
driver will call pci_channel_offline() to check for error condition and
issue non-raw MMIO reads to trigger early EEH detection in case of
hardware failures. This is necessary since the driver MMIO helper
funtions use raw accessors.
