Subject: [RFC v1 0/2] x86: kconfig: simplify APIC entries
Date: Tue, 10 Mar 2015 16:14:33 -0700	[thread overview]
Message-ID: <> (raw)

From: "Luis R. Rodriguez" <>

There's quite a bit of Kconfig entries related to X86_LOCAL_APIC
and X86_IO_APIC, and all for 32-bit purposes. Since 32-bit isn't in
a magical state of flux we now *should* know when to enable or disable
APIC stuff for these systems. Through history we've observed for
instance PCI_MSI requires these under specific scenarios, just enable
it for those learned scenarios and expect future requirements to also
be explicit about the requirements on 32-bit. This lets us remove
clutter (3 Kconfig entries) from x86 Kconfig simply for 32-bit build

  x86: kconfig: simplify enabling [IO]APIC for PCI_MSI
  x86: kconfig: remove UP [IO]APIC options
