This function will be useful in the DSCR test patches later in this series, so promote it to be shared by all powerpc selftests. Signed-off-by: Benjamin Gray Signed-off-by: Michael Ellerman Link: https://msgid.link/20230406043320.125138-3-bgray@linux.ibm.com

selftests/powerpc: Add test of stack expansion logic

2020-07-29T11:02:11Z

We have custom stack expansion checks that it turns out are extremely badly tested and contain bugs, surprise. So add some tests that exercise the code and capture the current boundary conditions. The signal test currently fails on 64-bit kernels because the 2048 byte allowance for the signal frame is too small, we will fix that in a subsequent patch.
