1bd5718ce5 x86: x86 TLS desc_struct cleanup
This cleans up the TLS code to use struct desc_struct and to separate the
encoding and installation magic from the interface wrappers.

cc6978528c x86: modify get_desc_base
This patch makes get_desc_base() receive a struct desc_struct,
and then uses its internal fields to compute the base address.
This is done at both i386 and x86_64, and then it is moved
to common header

80fbb69a8d x86: introduce fill_ldt
This patch introduces fill_ldt(), which populates a ldt descriptor
from a user_desc in once, instead of relying in the LDT_entry_a and
LDT_entry_b macros

efd1ca52d0 x86: TLS cleanup
This consolidates the four different places that implemented the same
encoding magic for the GDT-slot 32-bit TLS support.  The old tls32.c was
renamed and is now only slightly modified to be the shared implementation.

13abd0e504 x86: tls32 moved
This renames arch/x86/ia32/tls32.c to arch/x86/kernel/tls.c, which does
nothing now but paves the way to consolidate this code for 32-bit too.
