Hi Al, Please let me know if there are any concerns with this patch. If not, please ack this patch. I have attached the patch here for your reference - From: Narendra K <narendra_k@...l.com> Subject: [PATCH] Fix build failure when CONFIG_NLS is set to 'm' by allmodconfig This patch fixes the following build breakage introduced by the patch PCI:export ACPI _DSM provided firmware instance number and string to sysfs. (previously commit a6247cd4be20cb5439db5cb7b0b6cc67fdc8e2a2). http://marc.info/?l=linux-pci&m=129313294112736&w=1 drivers/built-in.o: In function `T.647': pci-label.c:(.text+0x28514): undefined reference to `utf16s_to_utf8s' This happens because 'make allmodconfig' sets CONFIG_NLS=m and makes 'utf16s_to_utf8s` unavailable to drivers/pci/pci-label.o which is built into vmlinux. This is fixed by making fs/nls/nls_base.c compile conditionally into vmlinux by introducing a new config option CONFIG_NLS_BASE which is selected by (ACPI || DMI || NLS).
