Subject[RFC PATCH] x86/acpi: Drop duplicate BOOT table initialization
From: Cao jin <>

ACPI BOOT table is initialized in both acpi_boot_table_init &
acpi_boot_init of setup_arch, but its usage is quite late at the end of
start_kernel. It should be safe to drop one of them. Since it is less
related with table init, drop it from there.

It existed since git repo is built, so it might has its reason? The
patch is not tested since I don't have BOOT table in my firmware.
