1dfdc15bb0 Only use the cache after the early stage of loading. This is
because calling mmap() etc. may use GOT which is not set up
yet. Use calloc() instead of mmap() in cases where this
was the case before (sparc64, powerpc, arm).

d1f2f1c3f3 Now that the kernel defines CACHE_LINE_SIZE in machine/param.h, use
that definition in the custom locking code for the run-time linker
rather than local definitions.

99227f1ec4 Unbreak the dynamic linker by not creating a cache for rtld-elf
itself. It needs mmap(2), which now needs getosreldate(3) and
which in turn uses a global variable to cache the result. This
cannot be done before linking is done.

9d34b1a911 o Fix the static TLS relocation. We were subtracting the size of
the TCB.
o  Use NULL for null pointer argument.
o  Replace magic 8 with TLS_TCB_SIZE.

0eb88f2029 Implement ELF symbol versioning using GNU semantics. This code aims
to be compatible with symbol versioning support as implemented by
GNU libc and documented by http://people.redhat.com/~drepper/symbol-versioning
and LSB 3.0.

Implement dlvsym() function to allow lookups for a specific version of
a given symbol.

6d5d786f80 Allow threading libraries to register their own locking
implementation in case default one provided by rtld is
not suitable.

Consolidate various identical MD lock implementation into
a single file using appropriate machine/atomic.h.

605f36fc1e No need to zero fill memory, mmapped anonymously. Kernel will
return pre-zeroed pages itself.
