* Drop support for the HP MMU. It was only found on two hp300 systems (modelsmiod2011-11-011-2/+1
| | | | | | | | 320 and 350), which have been unsupported since a bunch of release already, because this annoying MMU does not have TT registers (or if it does, it is not documented) and thus went in the way of PMAP_DIRECT for hp300. In other words: remove a bunch of code which was either #ifdef'ed out or had no chance to run in real life.

* Recommit the reverted sigacts change now that the NFS use-after-freeguenther2011-07-051-3/+3
| | | | | | | | problem has been tracked down. This fixes the sharing of the signal handling state: shared bits go in sigacts, per-rthread bits goes in struct proc. ok deraadt@

* if_downall() cannot be done MI in sys_reboot() because vfs_shutdown()deraadt2011-06-261-1/+3

* Move the bufcachepercent setting code to MI locations -- set it to 42%deraadt2011-06-051-15/+1
| | | | | | | for now; that is unlikely to hit some of the remaining starvation bugs. Repair the bufpages calculation too; i386 was doing it ahead of time (incorrectly) and then re-calculating it. ok thib
* Remove the freelist member from vm_physsegoga2011-05-301-5/+3
| | | | | | | | | | | | | | | | | | The new world order of pmemrange makes this data completely redundant (being dealt with by the pmemrange constraints instead). Remove all code that messes with the freelist. While touching every caller of uvm_page_physload() anyway, add the flags argument to all callers (all but one is 0 and that one already used PHYSLOAD_DEVICE) and remove the macro magic to allow callers to continue without it. Should shrink the code a bit, as well. matthew@ pointed out some mistakes i'd made. ``freelist death, I like. Ok.' ariane@ `I agree with the general direction, go ahead and i'll fix any fallout shortly'' miod@ (68k 88k and vax i could not check would build)
* - enable fenvmartynas2011-04-281-0/+3
| | | | - add nearbyint, nearbyintf and nearbyintl implemented using fenv
* Revert the sigacts diff: NFS can apparently retain pointers to processesguenther2011-04-181-3/+3
| | | | | | until they're zombies and then send them signals (for intr mounts). Until that is untangled, the sigacts change is unsafe. sthen@ was the victim for this one
* Use 'CLR(<buf>->b_flags, B_READ | B_WRITE | B_DONE)' regardless ofkrw2011-04-161-5/+5
| | | | | what the previous IO was. Less chance of copy and paste errors. Suggested by miod@.
* In days of yore one could arbitrarily whack buffer flags. Those dayskrw2011-04-151-5/+9
| | | | | | | | | | | | | 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@
* Correct the sharing of the signal handling state: stuff that shouldguenther2011-04-151-3/+3
| | | | | | | | | | | | 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. "I like the sound of this" tedu@
* Convert the kernel Makefiles to autogenerate dependencies during compilationguenther2011-04-151-19/+27
| | | | | | | | | 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.

* The various read*label() have stopped returning error strings for quitemiod2011-04-061-3/+2
| | | | | | some time, and return errnos instead. Fix or remove out-of-date comments mentioning the error strings, and make their callers check the return value against zero, not NULL.

* Force the DUID cache used to generate hw.disknames to be updatedkrw2011-02-261-1/+3

* Kill pmap_phys_address(), and force every driver's mmap() routine to returnmiod2010-12-263-6/+6
| | | | | | | a physical address [more precisely, something suitable to pass to pmap_enter()'sphysical address argument]. This allows MI drivers to implement mmap() routines without having to know about the pmap_phys_address() implementation and #ifdef obfuscation.

| | | | | early MD and late MI files must be split up so that vers.o can sneak between. Issue spotted by bluhm, repair discussed with miod
* move vers.o to before the other objects, so that it is not linked last.deraadt2010-12-021-4/+4
| | | | | | | | having it linked last is bad (on at least i386 and amd64) because the lapic is mapped over the start of the data segment -- savecore(8) then reads the version string for a fixed buffer space, and reads into the lapic area causing unintended side-effects (at least on Intel X5570 and X5680) found by pedro, discussed with kettenis and mpf and miod
* This is a first step towards getting rid of avail_start and avail_end in themiod2010-11-201-4/+2
| | | | | | | | | | | | | | kernel, currently limited to low-hanging fruit: these variables were used by bus_dma to specify the range in which to allocate memory, back when uvm_pglistalloc() was stupid and would not walk the vm_physseg[]. Nowadays, except on some platforms for early initialization, these variables are not used, or do not need to be global variables. Therefore: - remove `extern' declarations of avail_start and avail_end (or close cousins, such as arm physical_start and physical_end) from files which no longer need to use them. - make them local variables whenever possible. - remove them when they are assigned to but no longer used.
