Subject: arch/x86/include/asm/fixmap.h: mark __set_fixmap_offset as __always_inline
From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
When compiling arch/x86/kernel/early_printk_mrst.c with i386 allmodconfig,
gcc-4.1.0 generates an out-of-line copy of __set_fixmap_offset() whcih
contains a reference to __this_fixmap_does_not_exist which the compiler cannot
elide.
Marking __set_fixmap_offset() as __always_inline prevents this.
