The patch titled
x86_64 acpi: various cleanups
has been removed from the -mm tree. Its filename was
x86_64-acpi-various-cleanups.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: x86_64 acpi: various cleanups
From: David Rientjes <rientjes@xxxxxxxxxx>
In acpi_scan_nodes(), we immediately return -1 if acpi_numa <= 0, meaning we
haven't detected any underlying ACPI topology or we have explicitly disabled
its use from the command-line with numa=noacpi.
acpi_table_print_srat_entry() and acpi_table_parse_srat() are only referenced
within drivers/acpi/numa.c, so we can mark them as static and remove their
prototypes from the header file.
Likewise, pxm_to_node_map[] and node_to_pxm_map[] are only used within
drivers/acpi/numa.c, so we mark them as static and remove their externs from
the header file.
The automatic 'result' variable is unused in acpi_numa_init(), so it's
removed.
