Bruce Ashfield - June 18, 2013, 3:20 p.m.
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)

    [<c07ee258>] (console_map_init+0x44/0x58) from [<c07ee738>] (vty_init+0x16c/0x1b0)
    [<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.
