[Linux-stable-mirror] [PATCH v2 1/2] alpha: osf_sys.c: fix put_tv32 regression
by Arnd Bergmann
There was a typo in the new version of put_tv32() that caused an unguarded
access of a user space pointer, and failed to return the correct result in
gettimeofday(), wait4(), usleep_thread() and old_adjtimex().
This fixes it to give the correct behavior again.

[Linux-stable-mirror] [PATCH] schedutil: Reset cached freq if it is not in sync with next_freq
by Viresh Kumar
'cached_raw_freq' is used to get the next frequency quickly but should
always be in sync with sg_policy->next_freq. There is a case where it is
not and in such cases it should be reset to avoid switching to incorrect
frequencies.
Consider this case for example:
- policy->cur is 1.2 GHz (Max)
- New request comes for 780 MHz and we store that in cached_raw_freq.
- Based on 780 MHz, we calculate the effective frequency as 800 MHz.
- We then see the CPU wasn't idle recently and choose to keep the next
freq as 1.2 GHz.
- Now we have cached_raw_freq is 780 MHz and sg_policy->next_freq is 1.2
GHz.
- Now if the utilization doesn't change in then next request, then the
next target frequency will still be 780 MHz and it will match with
cached_raw_freq. But we will choose 1.2 GHz instead of 800 MHz here.

There is a problem if a device is removed while acpi_add_pm_notifier()
is still in progress, in which case with my patch the
acpi_remove_pm_notifier() called from the removal path may bail out
prematurely (that doesn't seem likely to happen, but still I don't see
why it cannot happen), so I'll just use your patch. :-)

Well, not really, so the above is OK.
However, I still would prefer to avoid adding the outer lock.
