Hi Christophe,
Thanks for this series. There are quite a few preliminary patches in it,
before you get to the PPC part, which fix up general build system or test
harness correctness issues. Since some of those affect all architectures
that are adding vDSO getrandom() support for 6.12, I'm going to
This series wires up getrandom() vDSO implementation on powerpc.
Tested on PPC32.
Performance on powerpc 885 (using kernel selftest):
~# ./vdso_test_getrandom bench-single
vdso: 250 times in 7.897495392 seconds
libc: 250 times in 56.091632232 seconds
