| |
2.6.33-stable review patch. If anyone has any objections, please let us know.
------------------
From: Rabin Vincent <rabin@rab.in>
commit d4d9959c099751158c5cf14813fe378e206339c6 upstream.
98e12b5a6e05413 ("ARM: Fix decompressor's kernel size estimation for ROM=y") broke the Thumb-2 decompressor because it added an entry in the LC0 table but didn't adjust the offset the Thumb-2 code uses to load the SP from that table. Fix it.
