commit: a6432ded299726f123b93d0132fead200551535c From: Wang YanQing <udknight@xxxxxxxxx> Date: Tue, 23 Apr 2013 01:19:19 +0200 Subject: ACPI: Fix wrong parameter passed to memblock_reserve Commit 53aac44 (ACPI: Store valid ACPI tables passed via early initrd in reserved memblock areas) introduced acpi_initrd_override() that passes a wrong value as the second argument to memblock_reserve(). Namely, the second argument of memblock_reserve() is the size of the region, not the address of the top of it, so make acpi_initrd_override() pass the size in there as appropriate.
