selftests/powerpc: Move shared headers into new include dir

2016-11-17T06:11:47Z

There are some functions, especially register related, which can be shared across multiple selftests/powerpc test directories. This patch creates a new include directory to store those shared files, so that the file layout becomes more neat.

selftests/powerpc: Rework FPU stack placement macros and move to header file

2016-10-04T09:10:11Z

The FPU regs are placed at the top of the stack frame. Currently the position expected to be passed to the macro. The macros now should be passed the stack frame size and from there they can calculate where to put the regs, this makes the use simpler. Also move them to a header file to be used in an different area of the powerpc selftests Signed-off-by: Cyril Bur Signed-off-by: Michael Ellerman

selftests/powerpc: Test the preservation of FPU and VMX regs across syscall

2016-03-02T12:34:46Z

Test that the non volatile floating point and Altivec registers get correctly preserved across the fork() syscall. fork() works nicely for this purpose, the registers should be the same for both parent and child Signed-off-by: Cyril Bur [mpe: Add include guards to basic_asm.h, minor formatting] Signed-off-by: Michael Ellerman
