It seems that mn10300 made it upstream after Jan Beulich's pci_dac_dma_*
cleanup work and still defines pci_dac_dma_supported(). This API is not
required by the PCI subsystem anymore, so remove it.

In current code it continues setup even if alloc_msi_entry() for MSI-X
is failed due to lack of memory.  It means arch_setup_msi_irqs() might
be called with msi_desc entries less than its argument nvec.

At least x86's arch_setup_msi_irqs() uses list_for_each_entry() for
dev->msi_list that suspected to have entries same numbers as nvec, and
it doesn't check the number of allocated vectors and passed arg nvec.
Therefore it will result in success of pci_enable_msix(), with less
vectors allocated than requested.

This patch fixes the error route to return -ENOMEM, instead of continuing
the setup (proposed by Matthew Wilcox).

Note that there is no iounmap in msi_free_irqs() if no msi_disc is
allocated.

Currently we reinit the ldisc on final tty close which is what the old code
did to ensure that if the device retained its termios settings then it had the
right ldisc. tty_ldisc_reinit does that but also leaves us with the reset
ldisc reference which is then leaked.

At this point we know the port will be recycled so we can kill the ldisc
off completely rather than try and add another ldisc free up when the kref
count hits zero.

At this point it is safe to keep the ldisc closed as tty_ldisc waiting
methods are only used from the user side, and as the final close we are
the last such reference. Interrupt/driver side methods will always use the
non wait version and get back a NULL.

2.6.31-rc introduced an architecture level set checker based on facility
bits. e.g. if the kernel is compiled to run only on z9, several facility
bits are checked very early and the kernel refuses to boot if a z9 specific
facility is missing.
Until now kvm on s390 did not implement the store facility extended (STFLE)
instruction. A 2.6.31-rc kernel that was compiled for z9 or higher did not
boot in kvm. This patch implements stfle.

This patch should go in before 2.6.31.
