Subject: [MIPS] Fix build errors related to wbflush.h on tx4927/tx4938.
X-Git-Tag: v2.6.19-rc2~210
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f5c70dd7f384db4c524c35288d9be3ed61ac41a9;p=linux-2.6

[MIPS] Fix build errors related to wbflush.h on tx4927/tx4938.

TX49 CPUs have a SYNC instruction so that CONFIG_CPU_HAS_WB is no
longer needed.
