s390: workaround invalid gcc-11 out of bounds read warning (2023-01-17 19:00:59 +0100)
----------------------------------------------------------------
s390 compile fix for 6.2-rc5
- Workaround invalid gcc-11 out of bounds read warning caused by s390's
S390_lowcore definition. This happens only with gcc 11.1.0 and 11.2.0.
The code which causes this warning will be gone with the next merge
window. Therefore just replace the memcpy() with a for loop to get rid of
the warning.
