Subject: ACPI: Fix wrong parameter passed to memblock_reserve
From: Wang YanQing <[email protected]>
commit a6432ded299726f123b93d0132fead200551535c upstream.
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.
