The patch titled
x86: acpi: use cpu_physical_id()
has been removed from the -mm tree. Its filename was
x86-acpi-use-cpu_physical_id.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: x86: acpi: use cpu_physical_id()
From: Mike Travis <travis@xxxxxxx>
This is from an earlier message from Christoph Lameter:
processor_core.c currently tries to determine the apicid by special casing
for IA64 and x86. The desired information is readily available via
cpu_physical_id()
on IA64, i386 and x86_64.
Signed-off-by: Christoph Lameter <clameter@xxxxxxx>
Additionally, boot_cpu_id needed to be exported to fix compile errors in
dma code when !CONFIG_SMP.
