Hello,
we observe that group imbalance bug can cause performance degradation
upto factor 10x on 4 NUMA server.
I have opened Bug 194231
https://bugzilla.kernel.org/show_bug.cgi?id=194231
for this issue.
The problem was first described in this paper
http://www.ece.ubc.ca/~sasha/papers/eurosys16-
On a Rockchip rk3399-based board during suspend/resume testing, we
found that we could get the console UART into a state where it would
print this to the console a lot:
serial8250: too much work for irq42
Followed eventually by:
NMI watchdog: BUG: soft lockup - CPU#0 stuck for 11s!
Upon debug

No need to update jiffies in txq->trans_start twice, it's supposed to be
done in netdev_start_xmit() and anyway is re-written. Also, no reason to
update trans time in case of an error.

Diving the divider by the multiplier before applying to the input.
When this would "divide by zero", divide the multiplier by the divider
first then multiply the input by this value.
Currently user2creds outputs zero when input value is bigger than the

In case of error, 'err' is known to be 0 here, because of the previous
test. Set it to a -ENOMEM instead.

This series adds a CPUfreq driver for the BMIPS SoCs. In the first
iteration only BMIPS5xxx SoCs are supported.
The very first patch contains updates to bmips_stb_defconfig that are
