Richard/Saul,

Here's the integration of a change from Khem to fix the gcc 4.8 ARM
boot issues.

I'm still seeing some quasi random issues, but this definitely fixes
the issue at hand, gets us up and running and is much better than 
what we had before.

The patch pretty much says everything else:

linux-yocto/3.8: fix gcc 4.8 ARM boot issues

Updating the linux-yocto-3.8 SRCREVs to fix a boot issue with ARM boards
when gcc 4.8 is used.

Without the following mainline backports:

  f200475 ARM: 7670/1: fix the memset fix
  8215b0e ARM: 7668/1: fix memset-related crashes caused by recent GCC (4.7.2) optimizations

The following trap will be seen on boot:

    [<c00fc3b8>] (kmem_cache_alloc_trace+0x54/0x210) from [<c039f074>] (con_insert_unipair+0xcc/0x11c)

    [<c07ee738>] (vty_init+0x16c/0x1b0) from [<c07edb68>] (tty_init+0x108/0x148)
    [<c07edb68>] (tty_init+0x108/0x148) from [<c07eead0>] (chr_dev_init+0xb4/0xd8)
    [<c07eead0>] (chr_dev_init+0xb4/0xd8) from [<c0008a18>] (do_one_initcall+0x11c/0x18c)
    [<c0008a18>] (do_one_initcall+0x11c/0x18c) from [<c07d89d0>] (kernel_init_freeable+0x16c/0x254)
    [<c07d89d0>] (kernel_init_freeable+0x16c/0x254) from [<c05a3810>] (kernel_init+0x18/0x160)
    [<c05a3810>] (kernel_init+0x18/0x160) from [<c000e530>] (ret_from_fork+0x14/0x20)
    Code: e593a000 e35a0000 0a000020 e5943014 (e79a1003)
    ---[ end trace e6c62de166779f86 ]---
    Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b

Moderate stress and board testing shows the fix to hold, and it is good for
broader testing.
