81c06b10bc [VOYAGER] fix up ptregs removal mess
Apparently whoever converted voyager never actually checked that the
patch would compile ...

Remove as much of the pt_regs references as possible and move the
remaining ones into line with what's in x86 generic.

c771746ef6 [VOYAGER] fix genirq mess
The implementation of genirq in x86 completely broke voyager (and
presumably visws).  Since it's plugged into so much of the x86
infrastructure, you can't expect it to work unconverted.

This patch introduces a voyager IRQ handler type and switches voyager
to the genirq infrastructure.

The crux of the matter is that modpost only checks the relocatable
sections. i386 vmlinux has none, so modpost does no checking on it (it
does on the modules).  However, sparc vmlinux has plenty of
relocatable sections because it is being built with 'ld -r' (to allow
for btfixup processing).  So for sparc, modpost does do a lot of
checking. Sure enough, running modpost on arch/sparc/boot/image yields
no output (i.e. all is well).

modpost.c check_sec_ref() has:
                /* We want to process only relocation sections and not .init */
                if (sechdrs[i].sh_type == SHT_RELA) {
			// check here
                } else if (sechdrs[i].sh_type == SHT_REL) {
			// check here
		}

baf4326e49 sh: interrupt exception handling rework
Kill off interrupt_table for all of the CPU subtypes, we now
default in to stepping in to do_IRQ() for _all_ IRQ exceptions
and counting the spurious ones, rather than simply flipping on
the ones we cared about. This and enabling the IRQ by default
automatically has already uncovered a couple of bugs and IRQs
that weren't being caught, as well as some that are being
generated far too often (SCI Tx Data Empty, for example).

The general rationale is to use a marker for interrupt exceptions,
test for it in the handle_exception() path, and skip out to
do_IRQ() if it's found. Everything else follows the same behaviour
of finding the cached EXPEVT value in r2/r2_bank, we just rip out
the INTEVT read from entry.S entirely (except for in the kGDB NMI
case, which is another matter).

Note that while this changes the do_IRQ() semantics regarding r4
handling, they were fundamentally broken anyways (relying entirely
on r2_bank for the cached code). With this, we do the INTEVT read
from do_IRQ() itself (in the CONFIG_CPU_HAS_INTEVT case), or fall
back on r4 for the muxed IRQ number, which should also be closer
to what SH-2 and SH-2A want anyways.

b611967de4 [PATCH] epoll_pwait()
Implement the epoll_pwait system call, that extend the event wait mechanism
with the same logic ppoll and pselect do.  The definition of epoll_pwait
is:

int epoll_pwait(int epfd, struct epoll_event *events, int maxevents,
                 int timeout, const sigset_t *sigmask, size_t sigsetsize);

The difference between the vanilla epoll_wait and epoll_pwait is that the
latter allows the caller to specify a signal mask to be set while waiting
for events.  Hence epoll_pwait will wait until either one monitored event,
or an unmasked signal happen.  If sigmask is NULL, the epoll_pwait system
call will act exactly like epoll_wait.  For the POSIX definition of
pselect, information is available here:

*) 3Dnow support for memcpy() et al. does not compile currently and fixing this
   is not trivial, so simply disable it; with this change, if one selects MK7
   UML compiles (while it did not).

b5cdb5797d [PATCH] uml: make UML_SETJMP always safe
If enable is moved by GCC in a register its value may not be preserved after
coming back there with longjmp().  So, mark it as volatile to prevent this;
this is suggested (it seems) in info gcc, when it talks about -Wuninitialized.
 I re-read this and it seems to say something different, but I still believe
this may be needed.

enabled.

21c935e529 [PATCH] uml: correct removal of pte_mkexec
Correct commit 5906e4171a - this makes more
sense: we turn pte_mkexec + pte_wrprotect to pte_mkread.  However, due to a
bug in pte_mkread, it does the exact same thing as pte_mkwrite, so this patch
improves the code but does not change anything in practice.  The pte_mkread
bug is fixed separately, as it may have big impact.

1875a48fed [PATCH] uml: revert wrong patch
Andi Kleen pointed out that -mcmodel=kernel does not make sense for userspace
code and would stop everything from working, and pointed out the correct fix
for the original bug (not easy to do for me).

Reverts part of commit 06837504de.
