[parisc-linux] NPTL: The Bad News.

[Carlos O'Donell]

The bad news is that I didn't work much on my thesis this long weekend.
The good news is that I fixed many serious flaws related to:

1. Stack direction, stack guards, and stack permissions.
2. Low level locking primitives returning the wrong values.
3. EAGAIN != EWOULDBLOCK snafu's
4. Compiler bugs.
5. Makefile bugs.

My current set of libc + tls + nptl failures is now down to:

make[2]: *** [libc-tls-nptl/math/test-float.out] Error 1
make[2]: *** [libc-tls-nptl/math/test-double.out] Error 1

make[2]: *** [libc-tls-nptl/math/test-idouble.o] Error 1

- These are cool.

make: *** [check] Error 2

- These elf ones are all bad news, and for a fact I know I will have
to track down DSO initializer and finalizer bugs.

Huzah.

Cheers,
Carlos.
