there doesnt seem to be any further lock other than the BKL:
00000001 0.558ms (+0.000ms): delay_tsc (__delay)
00000001 0.560ms (+0.001ms): __const_udelay (radeon_do_wait_for_fifo)
00000001 0.560ms (+0.000ms): __delay (radeon_do_wait_for_fifo)
00000001 0.560ms (+0.000ms): delay_tsc (__delay)
00000001 0.561ms (+0.001ms): __const_udelay (radeon_do_wait_for_fifo)
00000001 0.561ms (+0.000ms): __delay (radeon_do_wait_for_fifo)
00000001 0.561ms (+0.000ms): delay_tsc (__delay)
so unless the BKL is being relied on, it's safe to add the conditional
reschedule.
