Subject: Use ARRAY_SIZE() macro in i386 relocs.c file
X-Git-Tag: v2.6.21-rc1~71^2~21
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ca820181fc187af316a18b2700582663662c4012;p=linux-2.6

Use ARRAY_SIZE() macro in i386 relocs.c file

Change the explicit code in the relocs.c file to use ARRAY_SIZE()
and add a definition of ARRAY_SIZE() since this is a userspace program
and wouldn't include kernel.h.
