Subject: [PATCH 1/4] Add and use pkg-config for libgcrypt instead of -config
scripts.
From 839f38e5ecc22b7f1b837284bbbffac8cb32ab1e Mon Sep 17 00:00:00 2001
From: Trevor Gamblin <trevor.gamblin@windriver.com>

Subject: [PATCH] libgcrypt: fix m4 file for oe-core
Upstream-Status: Denied [upstream have indicated they don't want a
pkg-config dependency]
Modify libgcrypt pkgconfig specifically for oe-core. Changes
are based on a previous patch from RP, using wiggle to
incorporate the parts that aren't in the upstream pkgconfig
settings.
RP 2014/5/22
Upstream-Status: Inappropriate [oe-specific]

Subject: [PATCH 2/3] AES: move look-up tables to .data section and unshare between
processes
* cipher/rijndael-internal.h (ATTR_ALIGNED_64): New.
* cipher/rijndael-tables.h (encT): Move to 'enc_tables' structure.
(enc_tables): New structure for encryption table with counters before
and after.
(encT): New macro.
(dec_tables): Add counters before and after encryption table; Move
from .rodata to .data section.
(do_encrypt): Change 'encT' to 'enc_tables.T'.
(do_decrypt): Change '&dec_tables' to 'dec_tables.T'.
* cipher/cipher-gcm.c (prefetch_table): Make inline; Handle input
with length not multiple of 256.
(prefetch_enc, prefetch_dec): Modify pre- and post-table counters
to unshare look-up table pages between processes.

Subject: [PATCH 3/3] GCM: move look-up table to .data section and unshare
between processes
* cipher/cipher-gcm.c (ATTR_ALIGNED_64): New.
(gcmR): Move to 'gcm_table' structure.
(gcm_table): New structure for look-up table with counters before and
after.
(gcmR): New macro.
(prefetch_table): Handle input with length not multiple of 256.
(do_prefetch_tables): Modify pre- and post-table counters to unshare
look-up table pages between processes.
