[PATCH v7 10/15] acpi, numa: remove unneeded acpi_numa=1

From: David Daney <hidden>
Date: 2016-05-24 22:38:03
Also in: linux-acpi, lkml
Subsystem: the rest, x86 architecture (32-bit and 64-bit), x86 mm · Maintainers: Linus Torvalds, Thomas Gleixner, Ingo Molnar, Borislav Petkov, Dave Hansen, Andy Lutomirski, Peter Zijlstra

From: Hanjun Guo <redacted>

acpi_numa is default to 0, it's set to -1 when disable acpi numa or
when a bad SRAT is parsed, and it's only consumed in srat_disabled()
(compare it with 0) to continue parse the SRAT or not, so we don't
need to set acpi_numa to 1 when we get a valid SRAT entry.
