Subject: [PATCHv2 34/59] acpi: Remove __init from acpi table parsing functions
Date:   Wed, 31 Jul 2019 18:07:48 +0300

From: Alison Schofield <alison.schofield@intel.com>

ACPI table parsing functions are useful after init time.

For example, the MKTME (Multi-Key Total Memory Encryption) key
service will evaluate the ACPI HMAT table when the first key
creation request occurs.  This will happen after init time.
