2011-04-16Initialize %cr30 for proc0 with the address of proc0fpstate. Shouldn't reallyMark Kettenis
matter, since we shouldn't be using the FPU inside the kernel, but we need to initialize %cr30 with something, and this is more consistent than using the address of the pcb.

2011-04-16Fix kernel build after guenther@'s signal changes.Miod Vallat
2011-04-16Use 'CLR(<buf>->b_flags, B_READ | B_WRITE | B_DONE)' regardless ofKenneth R Westerback
what the previous IO was. Less chance of copy and paste errors. Suggested by miod@.

2011-04-16More than a decade ago, interrupt handlers on sparc started returning 0Theo de Raadt
(interrupt was not for me), 1 (positive interrupt was for me), or -1 (i am not sure...). We have continued with this practice in as many drivers as possible, throughout the tree. This makes some of the architectures use that information in their interrupt handler calling code -- if 1 is returned (and we know this specific machine does not have edge-shared interrupts), we finish servicing other possible handlers on the same pin. If the interrupt pin remains asserted (from a different device), we will end up back in the interrupt servicing code of course... but this is cheaper than calling all the chained interrupts on a pin. This does of course count on shared level interrupts being properly sorted by IPL. There have been some concerns about starvation of drivers which incorrectly return 1. Those drivers should be hunted down so that they return -1. ok and help from various people. In snaps for about a week now.

2011-04-15In days of yore one could arbitrarily whack buffer flags. Those daysKenneth R Westerback
are past. Use CLR() and SET() to modify necessary flags while leaving the flags used by the buffer cache in peace. Should make bufcache code much less confused about the state of the bufs used in reading/writing disklabels. Other such flag abuses no doubt await a visit. Errors in original diff found by miod@. ok beck@ deraadt@
2011-04-15Remove local variables that are no longer used after the last commitClaudio Jeker

2011-04-15Correct the sharing of the signal handling state: stuff that shouldPhilip Guenthe
be shared (p_sigignore, p_sigcatch, P_NOCLDSTOP, P_NOCLDWAIT) moves to struct sigacts, wihle stuff that should be per rthread (ps_oldmask, SAS_OLDMASK, ps_sigstk) moves to struct proc. Treat the coredumping state bits (ps_sig, ps_code, ps_type, ps_sigval) as per-rthread until our locking around coredumping is better. Oh, and remove the old SunOS-compat ps_usertramp member.

2011-04-15Convert the kernel Makefiles to autogenerate dependencies during compilationPhilip Guenthe
using the -MD option to cc, with -MP, -MT, and -MF where needed, converting "make depend" to a no-op. This increases parallelism for those using "make -j" and keeps the dependencies up to date with each compilation automatically. sparc and vax users will need to rebuild gcc with support for the -M[PTF] options before config'ing with this diff.

2011-04-10Extend the PCI memory address space to 36-bit. The first BIOSen that assignMark Kettenis
addresses >4GB to 64-bit BARs have started to appear. But as long as machines still support running 32-bit operating systems we don't expect to see BARs that aren't addressable using PAE. Fixes a panic reported by william@. ok deraadt@
