The platforms which support only IOAPIC mode and whose SCI INT >= 16,
pass SCI INT via FADT and not via MADT int src override structure.
In such cases current logic fails to handle it and throws error
"Invalid bus_irq %u for legacy override". This patch handles the above
mentioned case. While at it, also modify function mp_override_legacy_irq()
to use the newly introduced function mp_register_ioapic_irq().
This series is rebased on 'master' branch of
https://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git
Changes since v2:
Addressed the review comments by Thomas Gleixner <tglx@linutronix.de> to fix the
broken Signed-off-by chain, code clean up and some comments removal.
Changes since v1:
Patch is split into 2, separating actual fix and code cleanup
as suggested by Rafael.

The platforms which support only IOAPIC mode, pass the SCI information
above the legacy space (0-15) via the FADT mechanism and not via MADT.
In such cases the mp_override_legacy_irq() used by acpi_sci_ioapic_setup()
to register SCI interrupts fails for interrupts >= 16, since it is meant to
handle only legacy space and throws error "Invalid bus_irq %u for legacy
override". Hence add a new function to handle SCI interrupts >= 16 and
invoke it conditionally in acpi_sci_ioapic_setup().The code duplication
due to this new function will be cleaned up in a separate patch.

This reads way better, but I have a small nit pick. In the example I gave
you there were multiple paragraphs on purpose to separate the different
parts. So if I just split the above lump into separate paragraphs:
[1]
The platforms which support only IOAPIC mode, pass the SCI information
above the legacy space (0-15) via the FADT mechanism and not via MADT.
[2]
In such cases the mp_override_legacy_irq() used by acpi_sci_ioapic_setup()
to register SCI interrupts fails for interrupts >= 16, since it is meant to
handle only legacy space and throws error "Invalid bus_irq %u for legacy
override".
[3]
Hence add a new function to handle SCI interrupts >= 16 and
invoke it conditionally in acpi_sci_ioapic_setup().
[4]
The code duplication due to this new function will be cleaned up in a
separate patch.
then this is clearly structured:
[1] describes the context.
[2] describes the failure
[3] describes the solution
[4] is an extra note to tell the reviewer/reader that you are aware of the
code duplication and this is addressed later.
No need to resend. I can do that when picking it up.
> Co-developed-by: Sunil V L <sunil.vl@hpe.com>
I had a discussion with Greg about this tag which resulted in a patch so
it should be soon part of the official documentation:
https://lkml.kernel.org/r/20171116132309.GA8449@kroah.com
We agreed that both authors should add their Signed-off-by to document that
the work conforms with the Developer Certificate of Origin. I'll add that
if that's ok for you.
Thanks for following up!

x86/acpi: Handle SCI interrupts above legacy space gracefully
Platforms which support only IOAPIC mode, pass the SCI information above
the legacy space (0-15) via the FADT mechanism and not via MADT.
In such cases mp_override_legacy_irq() which is invoked from
acpi_sci_ioapic_setup() to register SCI interrupts fails for interrupts
greater equal 16, since it is meant to handle only the legacy space and
emits error "Invalid bus_irq %u for legacy override".
Add a new function to handle SCI interrupts >= 16 and invoke it
conditionally in acpi_sci_ioapic_setup().
The code duplication due to this new function will be cleaned up in a
separate patch.

x86/acpi: Reduce code duplication in mp_override_legacy_irq()
The new function mp_register_ioapic_irq() is a subset of the code in
mp_override_legacy_irq().
Replace the code duplication by invoking mp_register_ioapic_irq() from
mp_override_legacy_irq().
