With this .config: http://busybox.net/~vda/kernel_config,
after uninlining these functions have sizes and callsite counts
as follows:
__OUTPLLP: 61 bytes, 12 callsites
__INPLL: 79 bytes, 150 callsites
__OUTPLL: 82 bytes, 138 callsites
_OUTREGP: 101 bytes, 8 callsites
_radeon_msleep: 66 bytes, 18 callsites
_radeon_fifo_wait: 83 bytes, 24 callsites
_radeon_engine_idle: 92 bytes, 10 callsites
radeon_engine_flush: 105 bytes, 2 callsites
radeon_pll_errata_after_index_slow: 31 bytes, 11 callsites
radeon_pll_errata_after_data_slow: 91 bytes, 9 callsites
radeon_pll_errata_after_FOO functions are split into two parts:
the inlined part which checks corresponding rinfo->errata bit,
and out-of-line part which performs workaround magic per se.
Reduction in code size is about 49,500 bytes:
