Instead of hosting our outdated own fork, this commit now uses kernkonzept's nowadays available github source repositories. This hopefully simplifies updates, or cherry-picking single fixes.

Subject: [PATCH 03/15] Sigma0: raise sigma0's priority to maximum.
|
|
|
|
When sigma0 runs on a lower priority than the rest of the threads in the system
|
|
it might come to the point that while answering a page fault or I/O memory area
|
|
request the timeslice of the caller (core-pager) gets fully consumed. As long as
|
|
other threads are still executable and don't block sigma0 won't do progress
|
|
anymore, because it runs at the lowest priority. This commit simply sets
|
|
sigma0's priority to the highest in the system.
|
|
|
|
Was: 'sigma0_prio.patch'
