History
brooks 67ff9a5216 Remove an unneeded and incorrect memset(). 
On Variant I TLS architectures (aarch64, arm, mips, powerpc, and riscv)
the __libc_allocate_tls function allocates thread local storage memory
with calloc(). It then copies initialization data over the portions with
non-zero initial values. Before this change it would then pointlessly
zero the already zeroed remainder of the storage. Unfortunately the
calculation was wrong and it would zero TLS_TCB_SIZE (2*sizeof(void *))
additional bytes.

In practice, this overflow only matters if the TLS segment is sized such
that calloc() allocates a less than TLS_TCB_SIZE extra memory. Even
then, the likely result will be zeroing part of the next bucket. This
coupled with the impact being confined to Tier II platforms means there
will be no security advisory for this issue.
