sh: Add ftrace syscall tracing support

2009-07-06T11:16:33+00:00

Now that I've added TIF_SYSCALL_FTRACE the thread flags do not fit into
a single byte any more. Code testing them now needs to be aware of the
upper and lower bytes.

sh: Fix compiler error and include the definition of IS_ERR_VALUE

When arch/sh/include/asm/syscall_32.h is included from a file that
doesn't also include linux/err.h the following error is produced,

sh: Fix up spurious syscall restarting.

2009-01-29T02:56:03+00:00

The T-bit manipulation for syscall error checking had the side effect of
spuriously returning ERESTART* errno values over EINTR. So, we simplify
the error checking a bit and leave the T-bit alone.
