This patch was hanging around for some time while we were waiting
for the compiler situation to improve.. now that all is well again,
finally merge it.

A few interrupt handlers were never updated, fix them up.
We were missing the irq_regs conversion also, so do that
at the same time.

This has suffered a bit of bitrot, so we're a bit behind on the
syscalls. There were a few that were wrapped incorrectly as well,
caught by the syscall checker. Fix them all up.

These files are almost all the same.
This patch could be made even simpler if we don't mind POLLREMOVE turning
up in a few architectures that didn't have it previously (which should be
OK as POLLREMOVE is not used anywhere in the current tree).

Most architectures defined three macros, MK_IOSPACE_PFN(), GET_IOSPACE()
and GET_PFN() in pgtable.h. However, the only callers of any of these
macros are in Sparc specific code, either in arch/sparc, arch/sparc64 or
drivers/sbus.
This patch removes the redundant macros from all architectures except
sparc and sparc64.

This patch moves the die notifier handling to common code. Previous
various architectures had exactly the same code for it. Note that the new
code is compiled unconditionally, this should be understood as an appel to
the other architecture maintainer to implement support for it aswell (aka
sprinkling a notify_die or two in the proper place)
arm had a notifiy_die that did something totally different, I renamed it to
arm_notify_die as part of the patch and made it static to the file it's
declared and used at. avr32 used to pass slightly less information through
this interface and I brought it into line with the other architectures.

Add hooks to allow a paravirt implementation to track the lifetime of
an mm. Paravirtualization requires three hooks, but only two are
needed in common code. They are:
arch_dup_mmap, which is called when a new mmap is created at fork
arch_exit_mmap, which is called when the last process reference to an
mm is dropped, which typically happens on exit and exec.
The third hook is activate_mm, which is called from the arch-specific
activate_mm() macro/function, and so doesn't need stub versions for
other architectures. It's called when an mm is first used.

Now network timestamps use ktime_t infrastructure, we can add a new
ioctl() SIOCGSTAMPNS command to get timestamps in 'struct timespec'.
User programs can thus access to nanosecond resolution.

The line discipline numbers N_* are currently defined for each architecture
individually, but (except for a seeming mistake) identically, in
asm/termios.h. There is no obvious reason why these numbers should be
architecture specific, nor any apparent relationship with the termios
structure. The total number of these, NR_LDISCS, is defined in linux/tty.h
anyway. So I propose the following patch which moves the definitions of
the individual line disciplines to linux/tty.h too.
Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused
in the current kernel, but the patch still keeps the complete set in case
there are plans to use them yet.

Virtually index, physically tagged cache architectures can get away
without cache flushing when forking. This patch adds a new cache
flushing function flush_cache_dup_mm(struct mm_struct *) which for the
moment I've implemented to do the same thing on all architectures
except on MIPS where it's a no-op.

Pass struct dev pointer to dma_cache_sync()
dma_cache_sync() is ill-designed in that it does not have a struct device
pointer argument which makes proper support for systems that consist of a
mix of coherent and non-coherent DMA devices hard. Change dma_cache_sync
to take a struct device pointer as first argument and fix all its callers
to pass it.
