If anyone has any objections, please let me know. ------------------ From: Sebastian Ott [ Upstream commit 13edf7539211d8f7d0068ce3ed143005f1da3547 ] Initialization of the local acpi_object in acpi_processor_get_info() only sets the first 4 bytes to zero and is thus incomplete. This is indicated by messages like: acpi ACPI0007:be: Invalid PBLK length [166288104] Fix this by initializing all 16 bytes of the processor member of that union.
