[Syllable-kernel] Small kernel TLD patch for get_tld_addr()

[Kristian V. D. V. <va...@li...>]

I just want to run this past you all quickly before I go ahead and check this in.

The patch adds an additional pre-defined TLD, TLD_BASE, which gives us
the address of the thread data E.g. the address of the first TLD.  This allows
me to re-write get_tld_addr() to calculate the address of any TLD without
the need for a syscall.  This neatly removes a whole heap of regular syscalls
to get_tld_addr()

Any objections?  Note that this doesn't make any difference until I release
the matching Glibc, but it will be required at that point.
