    SubjectRe: [PATCH] Speedup SMP kernel on UP box
    Date
    In article <0C01A29FBAE24448A792F5C68F5EA47D238DE0@nasdaq.ms.ensim.com>,
    you write:
    >@@ -9,9 +9,15 @@
    > */
    >
    > #ifdef CONFIG_SMP
    >-#define LOCK "lock ; "
    >+#define LOCK "\n1:\tlock ; "
    >+#define LOCK_ADDR "\n" \
    >+ ".section .lock.init,\"a\"\n\t" \
    >+ ".align 4\n\t" \
    >+ ".long 1b\n" \
    >+ ".previous\n"


    Why not do:

    #define LOCK "1: lock ; \n" \
    ".section .lock.init,\"a\"\n" \
    ".align 4\n"\
    ".long 1b\n"\
    ".previous\n"

    Then you don't need the LOCK_ADDR macro, so most of atomic.h can be
    left as is. The assembler doesn't seem to care that there's a section
    change between the lock prefix and the instruction that it's locking.
