Hello!

The allocator function does mention "cleared".

2012-11-06  Uros Bizjak  <ubizjak@gmail.com>

	* config/i386/i386.c (ix86_init_machine_status): Do not
	explicitly clear tls_descriptor_call_expanded_p again.

Tested on x86_64-pc-linux-gnu {,-m32}, committed to mainline SVN, will
be backported to 4.7.

Uros.
