sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.
- Reorganize locking in UVM and provide extra serialisation for pmap(9).
New lock order: [vmpage-owner-lock] -> pmap-lock.
- Simplify locking in some pmap(9) modules by removing P->V locking.
- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).
- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.
- Unify /dev/mem et al in MI code and provide required locking (removes
kernel-lock on some ports). Also, avoid cache-aliasing issues.
Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.
Instead, prepare x68k_init() function for pre-main MD initialization as other
m68k ports and move uvm_page_physload() call and msgbuf initialization there.
Tested on X68030, but options EXTENDED_MEMORY is untested.
that causes unexpected panic during installation and
DIAGNOSTIC pool assertions.
Also fix bp->b_flags in writedisklabel(9) error path.
The problem was reported from Y.Sugahara during XM6i development,
and this fix is confirmed on both X68030 (by me) and XM6i (by Sugahara).
XXX: broken dkbad support (which makes struct cpu_disklabel larger
XXX: than 512 bytes) should be removed...
so that we include the source tree's sys/, machine/ and m68k/ headers,
and only as a last resort use DESTDIR's /usr/include. For some reason
the host's bootinfo.h got included ahead of the x68k variant, causing
a build failure in my case.
Problem was reported by isaki@.
On X680x0 (and most other machines other than ISA FDC),
the ready line from FDD is connected to FDC and fdc driver can
be notified of the ready state after fd_set_motor() by interrupts.
In this case no need to use callout(9) to wait the FDD motor stabilized,
and the callout(9) method used in ISA fdc(4) driver rather caused
infinite unhandled interrupts since callout(9) was no longer invoked
during interrupt storm after vmlocking2 merge, I guess.
Should be pulled up to netbsd-5.
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

Change all platforms accordingly. -D is added if MKREPRO is not yes and

MKREPRO now either.
