and large page support. This version is a bit more intelligent about
how it deals with kernel text pages.
Now that this is fixed, don't map the kernel text read-write if
DDB is configured.
- Return FALSE if the PTE does not have PG_V set (previously, you would
get always get true of the PDE was valid, even if the PTE was not).
- Teach it about 4MB pages.
in the non-MULTIPROCESSOR case (LOCKDEBUG requires it). Scheduler
lock is held upon entry to mi_switch() and cpu_switch(), and
cpu_switch() releases the lock before returning.
Largely from Bill Sommerfeld, with some minor bug fixes and
machine-dependent code hacking from me.
need to access this when we have the proclist locked for reading,
and thus cannot store it in the PCB (which may be swapped out).
As part of this, call pmap_activate() from cpu_switch() to switch
to the new address space, and refresh the PCB's copy of the LDT
selector from the pmap structure (see above paragraph). We need
to do this for MP support anyhow.
Fixes a "panic: spinlock_switchcheck: CPU 0 has 1 spin locks" via
gdt_compact() reported by Nathan Williams.
so that special setup functions needed for some CPUs will be run before
some things (like UVM) are inited.
Add vm_page_zero_enable = FALSE to the cyrix 6x86 case, as page zeroing
while idle causes problems.
while suspended. When waking up the power hooks are again called at
splhigh() and then the level is lowered.
This prevents interrupts from reaching a device before the power hook
has reinitialized it.
Under this option, if only one IRQ is available for the link,
we assumes that the IRQ is already connected, and configure
PCI Interrupt Configuration Register accordingly.
This is what Linux pcmcia-cs-3.1.19 does by default.
This fixes unconfigured pccbb interrupt problem of
Sharp Mebius MN-5500. It's interrupt router is ITExpress Inc. IT8330G.

- MB_LEN_MAX is increased to 32.
- To ensure binary compatibility for old executables
under multibyte locale, versioned setlocale is added.
- __mb_len_cur definision is added in setlocale.c
and enable it in stdlib.h .
It is also important for multibyte locale stuffs,
but I just forgot.
Avoid interpreting the upper 32 bits of 64-bit BARs as a 32-bit BAR.
Otherwise, the code would assume that the value 0 was incorrect and either:
(a) [on bus 0] "fix up" the address to some nonzero value, thus placing
the decoded address range outside of 32-bit address space, or
(b) [elsewhere] completely disable the device.
The fact that this behaviour depends on the bus number of the device is
already XXX'd.
XXX: This will need revisiting if and when we ever want to handle a PCI bus
XXX: with more than 32 bits of address space on an i386.
