4 Subject: [PATCH] fastboot: convert a few non-critical ACPI drivers to async initcalls
6 This patch converts a few non-critical ACPI drivers to async initcalls;
7 these initcalls (battery, button and thermal) tend to take quite a bit of
8 time (100's of milliseconds) due to the hardware they need to talk to,
9 but are otherwise clearly non-essential for the boot process.
