In commit f8924e770e ("x86: unify mp_bus_info"), the 32-bit
and 64-bit versions of MP_bus_info were rearranged to match each
other better. Unfortunately it introduced a regression: prior
to that change we used to always set the mp_bus_not_pci bit,
then clear it if we found a PCI bus. After it, we set
mp_bus_not_pci for ISA buses, clear it for PCI buses, and leave
it alone otherwise.
In the cases of ISA and PCI, there's not much difference. But
ISA is not the only non-PCI bus, so it's better to always set
mp_bus_not_pci and clear it only for PCI.
Without this change, Dan's Dell PowerEdge 4200 panics on boot
with a log indicating interrupt routing trouble unless the
"noapic" option is supplied. With this change, the machine
boots reliably without "noapic".

Other than sanity check and debug message, the x86 specific version of
memblock reserve/free functions are simple wrappers around the generic
versions - memblock_reserve/free().
This patch adds debug messages with caller identification to the

3. replace free_early with memblock_x86_free_range.
4. NO_BOOTMEM will switch to use memblock too.

6. because memblock_x86_free_range support partial free, we can remove some special care

-v2: Move reserve_brk() early
Before fill_memblock_area, to avoid overlap between brk and memblock_find_in_range()
that could happen We have more then 128 RAM entry in E820 tables, and
memblock_x86_fill() could use memblock_find_in_range() to find a new place for

So move reserve_brk() early before fill_memblock_area().

-v4: Treat RESERVED_KERN as RAM in memblock.memory. and they are already in

This fixes a regression in 2.6.35 from 2.6.34, that is
present for select models of Intel cpus when people are
using an MP table.
The commit cf7500c0ea
"x86, ioapic: In mpparse use mp_register_ioapic" started
calling mp_register_ioapic from MP_ioapic_info. An extremely
simple change that was obviously correct. Unfortunately
mp_register_ioapic did just a little more than the previous
hand crafted code and so we gained this call path.
The problem call path is:
MP_ioapic_info()
mp_register_ioapic()
io_apic_unique_id()
io_apic_get_unique_id()
get_physical_broadcast()
modern_apic()
lapic_get_version()
apic_read(APIC_LVR)
Which turned out to be a problem because the local apic
was not mapped, at that point, unlike the similar point
in the ACPI parsing code.
This problem is fixed by mapping the local apic when
parsing the mptable as soon as we reasonably can.
Looking at the number of places we setup the fixmap for
the local apic, I see some serious simplification opportunities.
For the moment except for not duplicating the setting up of the
fixmap in init_apic_mappings, I have not acted on them.
The regression from 2.6.34 is tracked in bug

When I introduced the global variable gsi_end I thought gsi_end on
io_apics was one past the end of the gsi range for the io_apic. After
it was pointed out the the range on io_apics was inclusive I changed
my global variable to match. That was a big mistake. Inclusive
semantics without a range start cannot describe the case when no gsi's
are allocated. Describing the case where no gsi's are allocated is
important in sfi.c and mpparse.c so that we can assign gsi numbers
instead of blindly copying the gsi assignments the BIOS has done as we
do in the acpi case.
To keep from getting the global variable confused with the gsi range
end rename it gsi_top.
To allow describing the case where no gsi's are allocated have gsi_top
be one place the highest gsi number seen in the system.

Long ago MP_ioapic_info was the primary way of setting up our
ioapic data structures and mp_register_ioapic was a compatibility
shim for acpi code. Now the situation is reversed and
and mp_register_ioapic is the primary way of setting up our
ioapic data structures.
Keep the setting up of ioapic data structures uniform by
having mp_register_ioapic call mp_register_ioapic.
This changes a few fields:
- type: is now hardset to MP_IOAPIC but type had to
bey MP_IOAPIC or MP_ioapic_info would not have been called.
- flags: is now hard coded to MPC_APIC_USABLE.
We require flags to contain at least MPC_APIC_USEBLE in
MP_ioapic_info and we don't ever examine flags so dropping
a few flags that might possibly exist that we have never
used is harmless.
- apicaddr: Unchanged
- apicver: Read from the ioapic instead of using the cached
hardware value in the MP table. The real hardware value
will be more accurate.
- apicid: Now verified to be unique and changed if it is not.
If the BIOS got this right this is a noop. If the BIOS did
not fixing things appears to be the better solution.
This adds gsi_base and gsi_end values to our ioapics defined with
the mpatable, which will make our lives simpler later since
we can always assume gsi_base and gsi_end are valid.

We found a system where the MP table MPC and MPF structures overlap.
That doesn't really matter because the mptable is not used anyways with ACPI,
but it leads to a panic in the early allocator due to the overlapping
reservations in 2.6.33.
Earlier kernels handled this without problems.
Simply change these reservations to reserve_early_overlap_ok to avoid
the panic.

We need to fall back from logical-flat APIC mode to physical-flat mode
when we have more than 8 CPUs. However, in the presence of CPU
hotplug(with bios listing not enabled but possible cpus as disabled cpus in
MADT), we have to consider the number of possible CPUs rather than
the number of current CPUs; otherwise we may cross the 8-CPU boundary
when CPUs are added later.
32bit apic code can use more cleanups (like the removal of vendor checks in
32bit default_setup_apic_routing()) and more unifications with 64bit code.
Yinghai has some patches in works already. This patch addresses the boot issue
that is reported in the virtualization guest context.

Move the find_smp_config() call to before bootmem is initialized.
Use reserve_early() instead of reserve_bootmem() in it.
This simplifies the code, we only need to call find_smp_config()
once and can remove the now unneeded reserve parameter from
x86_init_mpparse::find_smp_config.
We thus also reduce x86's dependency on bootmem allocations.
