The H_SET_MODE hcall returns H_P2 if a function is not implemented and all callers should handle this case. The call to enable relocation on exceptions currently prints an error message if the feature is not implemented. While H_SET_MODE was first introduced on POWER8 (which has relocation on exceptions), it has been now added on some POWER7 configurations (which does not). Check for H_P2 and print an informational message instead. Signed-off-by: NAnton Blanchard <anton@samba.org> Signed-off-by: NMichael Ellerman <mpe@ellerman.id.au>

LLVM doesn't support local named register variables and is unlikely to. current_thread_info is using one, fix it by moving it out and calling it __current_r1(). I gave it a bit of an obscure name because we don't want anyone else using it - they should use current_stack_pointer(). This specific case is performance critical and we can't afford to call a function to get it. Furthermore it isn't important to know exactly where in the stack we are since we mask the lower bits.

The build is broken with CONFIG_PPC32=y, CONFIG_FB_VGA16=y and CONFIG_VGA_CONSOLE=n. The problem is that vgacon_remap_base is not defined. It's used in: #define VGA_MAP_MEM(x,s) (x + vgacon_remap_base) Which is used in the vga16fb.c code. Digging down it seems vgacon_remap_base is never initialised. It used to be, back in arch/ppc (pplus.c and prep_setup.c), but none of that code ever made it to arch/powerpc. So given it's been unused for >6 years, remove it. Whether vga16fb.c works on 32-bit is another question, but this patch shouldn't affect it. Signed-off-by: NMichael Ellerman <mpe@ellerman.id.au>

On some platforms a 5 second timeout during boot might be quite long, so make it configurable. Run the loop at least once to let the user stop the boot by holding a key pressed. If the timeout is set to 0, don't wait for input, which can be used as a workaround if the boot hangs on random data coming in on the serial port.

Instead of passing in the stack address of the link register to be modified, just pass in the old value and return the new value and rely on ftrace_graph_caller to do the modification. This removes the exception handling around the stack update - it isn't needed and we weren't consistent about it. Later on we would do an unprotected modification: if (!ftrace_graph_entry(&trace)) { *parent = old; Signed-off-by: NAnton Blanchard <anton@samba.org> Signed-off-by: NMichael Ellerman <mpe@ellerman.id.au>

Running ftracetests on a box that mounted debugfs in two locations made the ftracetests fail. This is because the tests uses a grep of debugfs from the /proc/mounts file to find the debugfs mount point, and then appends "/tracing" to that string to get the tracing directory. If the debugfs directory is mounted twice, then that grep will return two answers and appending "/tracing" to a string with two lines will not work. Use "head -1" to only take the first mount point found. Acked-by: NMasami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Signed-off-by: NSteven Rostedt <rostedt@goodmis.org>
