x86/acpi: Mark acpica interrupt handlers MP-safe.

acpica has its own internal locking, and the interrupt handlers we

own locking.

x86: Split most of pmap.h into pmap_private.h or vmparam.h.

This way pmap.h only contains the MD definition of the MI pmap(9)
API, which loads of things in the kernel rely on, so changing x86
pmap internals no longer requires recompiling the entire kernel every
time.

Callers needing these internals must now use machine/pmap_private.h.
Note: This is not x86/pmap_private.h because it contains three parts:

1. CPU-specific (different for i386/amd64) definitions used by...

2. common definitions, including Xenisms like xpmap_ptetomach,
further used by...

3. more CPU-specific inlines for pmap_pte_* operations

So {amd64,i386}/pmap_private.h defines 1, includes x86/pmap_private.h
for 2, and then defines 3. Maybe we should split that out into a new
pmap_pte.h to reduce this trouble.

No functional change intended, other than that some .c files must
include machine/pmap_private.h when previously uvm/uvm_pmap.h
polluted the namespace with pmap internals.

Note: This migrates part of i386/pmap.h into i386/vmparam.h --
specifically the parts that are needed for several constants defined
in vmparam.h:

VM_MAXUSER_ADDRESS
VM_MAX_ADDRESS
VM_MAX_KERNEL_ADDRESS
VM_MIN_KERNEL_ADDRESS

Since i386 needs PDP_SIZE in vmparam.h, I added it there on amd64
too, just to keep things parallel.

Most of the boot procedure (especially page table setup and switch to
paged mode) is shared with native.
- change some x86_delay() to delay_func(), which points to x86_delay() for
native/HVM, and xen_delay() for PVH

Xen changes:
- remove Xen bits from init_x86_64_ksyms() and init386_ksyms()
and move to xen_init_ksyms(), used for both PV and PVH
- set ISA no-legacy-devices property for PVH
- factor out code from Xen's cpu_bootconf() to xen_bootconf()
in xen_machdep.c
- set up a specific pvh_consinit() which starts with printk()
(which uses a simple hypercall that is available early) and switch to
xencons when we can use pmap_kenter_pa().

Add acpi_intr_mask() and acpi_intr_unmask() which, following the pre-existing
ACPI software layering model, are wrappers around acpi_md_intr_mask() and

Attempt to obtain ACPI RSDP from the hypervisor for Xen PV

There are three possible way of obtaining the ACPI RSDP
- From Extended BIOS Data Area (EBDA) when kernel or Xen was booted from
BIOS bootstrap
- From EFI SystemTable when kernel is booted from EFI bootstrap
- When Xen is booted from EFI bootstrap, EBDA is not mapped, and EFI
SystemTable is not passed to the kernel. The only way to go is to
obtain ACPI RSDP trhough an hypercall.

Note: EFI bootstrap support for booting Xen has not yet been committed.

XENPVH - sources required for support for XEN in PVH mode.

Allow registering ACPI interrupt handlers with a xname.
AcpiOsInstallInterruptHandler(), part of ACPICA API, doesn't allow passing

for this purpose, and change acpi_md_OsInstallInterruptHandler() to
accept and use the xname (ia64 doens't use it).
The xname was hardcoded to "acpi SCI" in the
x86 acpi_md_OsInstallInterruptHandler(), so I make
AcpiOsInstallInterruptHandler() call
AcpiOsInstallInterruptHandler_xname with xname = "acpi SCI".

Now 'vmstat -i' shows the device's name instead of "acpi SCI" for for i2c HID
interrupts.

Follow IA-64 with the x86-specific ACPI MD functions and move these where
they belong to. Remove an unused function. Minor KNF. No functional change.

x86: Split most of pmap.h into pmap_private.h or vmparam.h.

This way pmap.h only contains the MD definition of the MI pmap(9)
API, which loads of things in the kernel rely on, so changing x86
pmap internals no longer requires recompiling the entire kernel every
time.

Callers needing these internals must now use machine/pmap_private.h.
Note: This is not x86/pmap_private.h because it contains three parts:

1. CPU-specific (different for i386/amd64) definitions used by...

2. common definitions, including Xenisms like xpmap_ptetomach,
further used by...

3. more CPU-specific inlines for pmap_pte_* operations

So {amd64,i386}/pmap_private.h defines 1, includes x86/pmap_private.h
for 2, and then defines 3. Maybe we should split that out into a new
pmap_pte.h to reduce this trouble.

No functional change intended, other than that some .c files must
include machine/pmap_private.h when previously uvm/uvm_pmap.h
polluted the namespace with pmap internals.

Note: This migrates part of i386/pmap.h into i386/vmparam.h --
specifically the parts that are needed for several constants defined
in vmparam.h:

VM_MAXUSER_ADDRESS
VM_MAX_ADDRESS
VM_MAX_KERNEL_ADDRESS
VM_MIN_KERNEL_ADDRESS

Since i386 needs PDP_SIZE in vmparam.h, I added it there on amd64
too, just to keep things parallel.

- Define a device call for PCI bus instances to fetch a direct child's

x86 changes:

Most of the boot procedure (especially page table setup and switch to
paged mode) is shared with native.
- change some x86_delay() to delay_func(), which points to x86_delay() for
native/HVM, and xen_delay() for PVH

Xen changes:
- remove Xen bits from init_x86_64_ksyms() and init386_ksyms()
and move to xen_init_ksyms(), used for both PV and PVH
- set ISA no-legacy-devices property for PVH
- factor out code from Xen's cpu_bootconf() to xen_bootconf()
in xen_machdep.c
- set up a specific pvh_consinit() which starts with printk()
(which uses a simple hypercall that is available early) and switch to
xencons when we can use pmap_kenter_pa().

Add acpi_intr_mask() and acpi_intr_unmask() which, following the pre-existing
ACPI software layering model, are wrappers around acpi_md_intr_mask() and
acpi_md_intr_unmask(), which in turn are wrappers around intr_mask() and

Attempt to obtain ACPI RSDP from the hypervisor for Xen PV

There are three possible way of obtaining the ACPI RSDP
- From Extended BIOS Data Area (EBDA) when kernel or Xen was booted from
BIOS bootstrap
- From EFI SystemTable when kernel is booted from EFI bootstrap
- When Xen is booted from EFI bootstrap, EBDA is not mapped, and EFI
SystemTable is not passed to the kernel. The only way to go is to
obtain ACPI RSDP trhough an hypercall.

Note: EFI bootstrap support for booting Xen has not yet been committed.

Allow registering ACPI interrupt handlers with a xname.
AcpiOsInstallInterruptHandler(), part of ACPICA API, doesn't allow passing

for this purpose, and change acpi_md_OsInstallInterruptHandler() to
accept and use the xname (ia64 doens't use it).
The xname was hardcoded to "acpi SCI" in the
x86 acpi_md_OsInstallInterruptHandler(), so I make
AcpiOsInstallInterruptHandler() call
AcpiOsInstallInterruptHandler_xname with xname = "acpi SCI".

Now 'vmstat -i' shows the device's name instead of "acpi SCI" for for i2c HID
interrupts.

Attempt to obtain ACPI RSDP from the hypervisor for Xen PV

There are three possible way of obtaining the ACPI RSDP
- From Extended BIOS Data Area (EBDA) when kernel or Xen was booted from
BIOS bootstrap
- From EFI SystemTable when kernel is booted from EFI bootstrap
- When Xen is booted from EFI bootstrap, EBDA is not mapped, and EFI
SystemTable is not passed to the kernel. The only way to go is to
obtain ACPI RSDP trhough an hypercall.

Note: EFI bootstrap support for booting Xen has not yet been committed.

CID/1325751: Avoid possible 32 bit overflow.

PCI Extended Configuration stuff written by nonaka@:
- Add PCI Extended Configuration Space support into x86.
- Check register offset of pci_conf_read() in MD part. It returns (pcireg_t)-1
if it isn't accessible.
- Decode Extended Capability in PCI Extended Configuration Space.
Currently the following extended capabilities are decoded:
- Advanced Error Reporting
- Virtual Channel
- Device Serial Number
- Power Budgeting
- Root Complex Link Declaration
- Root Complex Event Collector Association
- Access Control Services
- Alternative Routing-ID Interpretation
- Address Translation Services
- Single Root IO Virtualization
- Page Request
- TPH Requester
- Latency Tolerance Reporting
- Secondary PCI Express
- Process Address Space ID
- LN Requester
- L1 PM Substates
The following extended capabilities are not decoded yet:
- Root Complex Internal Link Control
- Multi-Function Virtual Channel
- RCRB Header
- Vendor Unique
- Configuration Access Correction
- Multiple Root IO Virtualization
- Multicast
- Resizable BAR
- Dynamic Power Allocation
- Protocol Multiplexing
- Downstream Port Containment
- Precision Time Management
- M-PCIe
- Function Reading Status Queueing
- Readiness Time Reporting
- Designated Vendor-Specific

acpi_md_findoverride is only used when NIOAPIC > 0, so don't provide it
otherwise.

Correct acpi_md_OsWritable() logic so that it can return TRUE.

yet more fixes for PR 47648 / PR 47016:
when using a temporary mp_intr_map, initialize the "flags" field
as well as "redir" since apic_set_redir() uses both. fix how
the flags field is change when applying an override, the trigger
and polarity sub-fields aren't just one bit like they are in redir.

redo the ACPI interrupt handler setup again, this time handling
MADT overrides that change the pin as well as the polarity.
fixes PR 47648.

locate PCI buses and determine their bus numbers using the info
previously extracted from ACPICA rather than trying to figure it out again.
allow PCI buses that don't have a _PRT method.
