    Subject[085/197] ARM: 6031/1: fix Thumb-2 decompressor
    2.6.32-stable review patch.  If anyone has any objections, please let us know.


    From: Rabin Vincent <>

    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.
