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.
The onboard Adaptec 7890 on my Dell Precision Workstation 410 works again.
- Use PCI_INTERRUPT_PIN_MAX and I386_PCI_INTERRUPT_LINE_NO_CONNECTION
instead of magic number.
the Following changes are
{Modified with,Approved by} UCHIYAMA Yasushi <uch@netbsd.org>:
- Do not touch a PIRQ router, if the PIRQ is already routed
by the BIOS, or no appropriate IRQ is found for the PIRQ.
The latter prevents a panic on the machine of Frank van der Linden.
- Do not modify a PCI Interrupt Configuration register,
if it is already set by the BIOS, even if it is inconsistent
with the PCI IRQ routing table provided by the BIOS.
(The PCI Interrupt Configuration register seems to be more reliable
than the PCI IRQ routing table.)
This is needed to prevent a incorrect header_fixup() caused
by the incorrect PIR table on a Panasonic Let's Note AL-N2T516J5.
Provide "options PCIBIOS_INTR_FIXUP_FORCE" to retain
previous behavior, i.e. believe the PCI IRQ routing table
and ignore the PCI Interrupt Configuration register.
Although I'm not sure this is really needed.
- Do not modify a PCI Interrupt Configuration register,
if appropriate IRQ is not found for the link.
- Move a pciintr_icu_getclink() call and a pciintr_icu_get_intr()
call from pciintr_link_fixup() to pciintr_link_alloc(),
and only allocate pciintr_link_map if those calls succeeded.
This reduces number of calls of pciintr_icu_getclink(),
and also avoid necessity to validate a clink value in
ICU's {get,set}_{intr,trigger}() functions.
The sanity checks are not removed yet, though.
- Fix uninitialized usage of variable `bitmap' on stage 3
of pciintr_link_fixup().
- Remove a member variable `old_irq' from struct pciintr_link_map.
- Always use 0x%02x for printf format of canonical link value.
- Use DIAGNOSTIC instead of PCIINTR_DEBUG for really weird situation.

- add several debug printf which can be enabled by FIRESTARDEBUG.
