selftests/powerpc: Add uaccess flush test2021-04-22T15:38:03+00:00Thadeu Lima de Souza Cascardocascardo@canonical.com2021-02-25T06:19:49+00:00urn:sha1:da650ada100956b0f00aa4fe9ce33103378ce9ca
Also based on the RFI and entry flush tests, it counts the L1D misses
by doing a syscall that does user access: uname, in this case.

selftests/powerpc: refactor entry and rfi_flush tests2020-11-19T12:47:23+00:00Daniel Axtensdja@axtens.net2020-11-17T05:59:15+00:00urn:sha1:0d239f3b03efc78fb5b290aff6c747fecd3b98cb
For simplicity in backporting, the original entry_flush test contained
a lot of duplicated code from the rfi_flush test. De-duplicate that code.
