2006-10-12[VOYAGER] fix up ptregs removal messJames Bottomley
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. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-10-12[VOYAGER] fix genirq messJames Bottomley
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. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

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 } Signed-off-by: Martin Habets <errandir_news@mph.eclipse.co.uk> Signed-off-by: David S.

2006-10-12sh: interrupt exception handling reworkPaul Mundt
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.

2006-10-11[PATCH] epoll_pwait()Davide Libenzi
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.
