regression update for 21-rc6:

1) all s2ram and NO_HZ related things seem to be resolved on my macbook
pro, also 
CONFIG_HPET_TIMER=y
CONFIG_HPET_EMULATE_RTC=y

don't break resume anymore.

2) However I am still having problems with
+CONFIG_HIGH_RES_TIMERS=y
+CONFIG_HPET=y
+CONFIG_HPET_MMAP=y
although the machine resumes, I've managed to get the attached oops.

3) Subject    : SATA breakage on resume

Status     : unknown

I am still seeing these messages after a suspend/resume cycle (though
all devices work even after multiple suspend/resume cycles)

ATA: abnormal status 0x80 on port 0x000140df
ata3.01: revalidation failed (errno=-2)
ata3: failed to recover some devices, retrying in 5 secs
ata1.00: configured for UDMA/33
ATA: abnormal status 0x7F on port 0x000140df
ATA: abnormal status 0x7F on port 0x000140df
ata3.01: configured for UDMA/133

So that's been a big step forward...
