[PATCH 6/6] x86/idt: Make const __initconst

Andi Kleen
2017-12-22T00:27:12Z

From: Andi Kleen <ak@linux.intel.com>

const variables must use __initconst, not __initdata. Fix this up
for the new IDT tables recently added, which got it consistently wrong.

Fixes a whole range of commits between
16bc18d895ce x86/idt: Move 32-bit idt_descr to C code
and
dc20b2d52653 x86/idt: Move interrupt gate initialization to IDT code
