Those macros in my patch are copied directly from process.c where
get_thread_area is implemented. Since the purpose of
PTRACE_GET_THREAD_AREA is to match what get_thread_area does, it's correct
that it match.
But I think you are right that the definition is wrong. It's obviously
suspect that two things are defined using the same bit:
#define GET_32BIT(desc) (((desc)->b >> 23) & 1)
#define GET_LIMIT_PAGES(desc) (((desc)->b >> 23) & 1)
This should be fixed in both process.c and ptrace.c together.
