Subject: x86/acpi: move pin_programmed bit map to io_apic.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bdfe8ac153546537ed24de69610ea781a734f785;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

x86/acpi: move pin_programmed bit map to io_apic.c

Prepare to call setup_io_apic_routing() in pcibios_irq_enable()
also remove not needed member apic_id.

[ Impact: clean up, prepare for future change ]
