git-x86, in commit 70aa1bd3839e3ec74ce65316528a82570e8de666, changed
a lot of the sigcontext field names. This patch changes UML usage to

This patch finishes the unification of system.h file.
i386 needs a constant to be defined, and it is defined inside an ifdef.
Other than that, pretty much nothing but includes are left in the arch

This patche changes the native_write_msr() and friends interface
to explicitly take 2 32-bit registers instead of a 64-bit value.
The change will ease the merge with 64-bit code. As the 64-bit
value will be passed as two registers anyway in i386,
the PVOP_CALL interface has to account for that and use low/high parameters
It would force the x86_64 version to be different.
The change does not make i386 generated code less efficient. As said above,
it would get the values from two registers anyway.

commit c434b7a6ae
(x86: avoid wasting IRQs for PCI devices)
created a concept of "IRQ compression" on i386
to conserve IRQ numbers on systems with many
sparsely populated IO APICs.
The same scheme was also added to x86_64,
but later removed when x86_64 recieved an IRQ over-haul
that made it unnecessary -- including per-CPU
IRQ vectors that greatly increased the IRQ capacity
on the machine.
i386 has not received the analogous over-haul,
and thus a previous attempt to delete IRQ compression
from i386 was rejected on the theory that there may
exist machines that actually need it. The fact is
that the author of IRQ compression patch was unable
to confirm the actual existence of such a system.
As a result, all i386 kernels with IOAPIC support
pay the following:
1. confusion
IRQ compression re-names the traditional IOAPIC
pin numbers (aka ACPI GSI's) into sequential IRQ #s:
ACPI: PCI Interrupt 0000:00:1c.0[A] -> GSI 20 (level, low) -> IRQ 16
ACPI: PCI Interrupt 0000:00:1c.1[B] -> GSI 21 (level, low) -> IRQ 17
ACPI: PCI Interrupt 0000:00:1c.2[C] -> GSI 22 (level, low) -> IRQ 18
ACPI: PCI Interrupt 0000:00:1c.3[D] -> GSI 23 (level, low) -> IRQ 19
ACPI: PCI Interrupt 0000:00:1c.4[A] -> GSI 20 (level, low) -> IRQ 16
This makes /proc/interrupts look different
depending on system configuration and device probe order.
It is also different than the x86_64 kernel running
on the exact same system. As a result, programmers
get confused when comparing systems.
2. complexity
The IRQ code in Linux is already overly complex,
and IRQ compression makes it worse. There have
already been two bug workarounds related to IRQ
compression -- the IRQ0 timer workaround and
the VIA PCI IRQ workaround.
3. size
All i386 kernels with IOAPIC support contain an int[4096] --
a 4 page array to contain the renamed IRQs.
So while the irq compression code on i386 should really
be deleted -- even before merging the x86_64 irq-overhaul,
this patch simply disables it on all high volume systems
to avoid problems #1 and #2 on most all i386 systems.
A large system with pin numbers >=64 will still have compression
to conserve limited IRQ numbers for sparse IOAPICS. However,
the vast majority of the planet, those with only pin numbers < 64
will use an identity GSI -> IRQ mapping.
