LWP private support / TLS support
Joerg Sonnenberger
I've just committed the first major step to TLS support on NetBSD.
The Alpha part is not complete at the moment, since it requires some
changes to the context switching code I can't test. What is needed
should be approximately:
(1) Call PAL_wdunique in cpu_switchto to ensure that the value is
updated.
(2) Remove the #if 0 around __HAVE___LWP_GETPRIVATE_FAST in types.h.
After a rebuild of libpthread, the ATF test cases for libpthread should
still work.

Would you like console (and RCM/SRM) access to a DS10L for
testing?
I probably have some other Alpha platforms around here (much
older) that could be made available as well.

this is a follow up to the earlier mail. Once the issues with the uniq
register are sorted out, the attached patch should provide the actual
relocations. Adding __HAVE_TLS_VARIANT_I to alpha/include/types.h should
be enough for the rest to work.
