- remove initialzation of physmem since it's properly initialized
before pmap_bootstrap() using a value passed from bootloader and
sanity possible maximum value is not necessary
- remove cn_tab = NULL initialization because no worth to patch it
Tested on NWS-1750.
unwanted sideeffects in the RB_ASKNAME case. This fixes PR/46732.
No longer wrap MD cpu_rootconf(), as hp300 port stores reboot information
as a side effect. Instead call MI rootconf() from MD code which makes
rootconf() now a wrapper to setroot().
Adjust several MD routines to set the global booted_device,booted_partition
variables instead of passing partial information to setroot().
Make cpu_rootconf(9) describe the calling order.
for ports which don't bother to have unnecessary bus_dma(9) implementation
to appease MI driver modules that require bus_dma_tag_t.
For amiga, move <m68k/bus_dma.h> inclusion from <machine/pci_machdep.h>
to <machine/bus.h> since amiga will want actual bus_dma(9) in future
for PCI devices.
Fixes builds on sys/modules/if_axe etc on ancient ports.
"Sounds good" from martin@ on port-m68k@.
pmap_init() is called, and the initial kernel PT pages aren't enough
for the allocations pmap_init(). This fails because pmap_kenter_pa()
tries to allocate a new kernel PT page and traps because the pmap has
not been initialized. When computing the number if initial kernel PT
pages, include enough to allow kmem to map the physical memory. This
should fix PR/45915. OK by releng@. One mac68k system has been verified
to boot. Volunteers to test the others welcome. Amigas with at least
up to 128MB of memory were OK, but larger memory will need some adjusting.
for crash(8) as amiga and sun3. There are _KERNEL protections in it.
Briefly tested by "build.sh -m news68k -U build".
Further possible botch will be fixed later.
the device lock in relevant places. avoid doing so while actually dumping.
tested i386 crash dumps still work, and that all touched files compile.
fixes PR#45705.
68030/68851 initialization paths.
Pointed out by isaki@ per observation of ATC status on XM6i emulator.
Tested on TT030, HP362, NWS-1750, and X68030 by me.
XXX: probably we can remove existing pflusha or TBIA calls after MMU turned

source file as the entropy-pool code itself. Move it to std. This
will be cleaned up more when I split the sources up as they should be.
This fixes build breaks on several ports. Thanks to Havard Eidnes for
pointing them out.

- map 0xc0000000-0xffffffff PA region (which is mirror of PA 0x0-0x3fffffff)
to the same VA via %tt0 and %tt1 registers and move KVA space accordingly
(like luna68k does for its devices)
- save trap #0 vector for PROM function calls in early bootstrap
and register it to trap #14 to call it from kernel for console output
- add dumb romcall based tty attachment taken from src/sys/dev/ofw/ofcons.c
- add rom function call stubs from news68k/stand/common/romcalls.S
- remove IIOV() macro for device registers where now mapped PA==VA via %tt1
XXX: romcons is not enabled yet because there is no generic interface
XXX: to attach wskbd(4) to non wsdisplay(4) devices like this romcons.
Note:
- ENTRY_NOPROFILE() is okay since they are used only for debug printf
- they are declared to return int so no need to put a return value into %a0

This is used by disk tools such as disklabel(8) to dynamically decide is
the undelyling platform uses a disklabel-in-mbr-partition or not
(instead of using a compile-time list of ports).
getlabelusesmbr() reads the sysctl kern.labelusesmbr, takes its value from the
machdep #define LABELUSESMBR.
For evbmips, make LABELUSESMBR 1 if the platform uses pmon
as bootloader, and 0 (the previous value) otherwise.
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.

formed the core changes of this branch.
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),

Change all platforms accordingly. -D is added if MKREPRO is not yes and
wasn't present before. Platforms that didn't use -D don't depend on
MKREPRO now either.
