Message-ID: <20110223131536.GA16707@fedora14-r610.blr.amer.dell.com> Date: Wed, 23 Feb 2011 18:24:31 +0530 From: <Narendra_K@...l.com> To: <viro@...iv.linux.org.uk>, <jbarnes@...tuousgeek.org> CC: <mjg@...hat.com>, <sfr@...b.auug.org.au>, <linux-kernel@...r.kernel.org>, <linux-next@...r.kernel.org>, <Shyam_Iyer@...l.com>, <Matt_Domsch@...l.com>, <Charles_Rose@...l.com>, <Jordan_Hargrave@...l.com> Subject: [PATCH] Fix build failure when CONFIG_NLS is set to 'm' by allmodconfig Hello, This patch fixes the build breakage as described in the post http://marc.info/?l=linux-next&m=129478755528194&w=2 while compiling the patch - http://marc.info/?l=linux-netdev&m=129846468529049&w=2 ([PATCH V3] Export ACPI _DSM provided firmware instance number and string name to sysfs). Hi Al, If this patch is acceptable, please consider for inclusion. 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 '[PATCH V3] Export ACPI _DSM provided firmware instance number and string to sysfs'. 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).
