I failed to notice that the series has been finally committed, so resent it. Of
course Hongtao can add the removed function back if he needs to.
And by the way, while revisiting the series I've noticed that though the patch
4/4 basically reverts [1], it leaves
#define MPIC_GREG_GLOBAL_CONF_1 0x00030
in arch/powerpc/include/asm/mpic.h untouched. That define also loses its uses
after applying the patch. Compare the following hunk in today's patch w/ the one
you committed:
@@ -33,11 +33,6 @@
#define MPIC_GREG_GCONF_NO_BIAS 0x10000000
#define MPIC_GREG_GCONF_BASE_MASK 0x000fffff

- (((r) << 28) & MPIC_GREG_GLOBAL_CONF_1_CLK_RATIO_MASK)
#define MPIC_GREG_VENDOR_0 0x00040
#define MPIC_GREG_VENDOR_1 0x00050
#define MPIC_GREG_VENDOR_2 0x00060
So the question is, should #define MPIC_GREG_GLOBAL_CONF_1 have been also
removed, or could be left as is?
