[PATCH v2 0/2] ACPI: Fix a regression of the table checksum verification.

[Lv Zheng <zetalog@gmail.com>]

From: Lv Zheng <lv.zheng@intel.com>

There is a warning message triggered by the early table chekcusm
verification during boot. Large tables cannot be installed on x86 platforms
due to this failure. The root cause is the size limitation of the current
x86 early mapping implementation, it's thus not suitable to be used to map
ACPI tables.

This patchset fixes this regression by stopping verifying table checksums
during the early boot stage.

Lv Zheng (2):
  ACPICA: Tables: Add mechanism to control early table checksum
    verification.
  ACPI: Fix regressions that x86 Linux kernel suffers from early
    mapping size limitation.
