Regresion testing for Microblaze: here 4 tests are from my regresion testing for Microblaze kernel debug. There is one extension for testing aligned/unaligned get/put_user macros. The rest of changes are easy. [PATCH 2/4] tst_is_cwd: Add support for ramfs: I added support for testing ramfs and add together tests for nfs, tmpfs and ramfs. Signed-off-by: Michal Simek <monstr@monstr.eu>.
