#     powerpc/config: powernv_defconfig updates
#     
#     For consideration:
#     
#     * Add NVDIMM support - Enables greater testing, mambo device.
#     * Add IPv6 support built in + additional modules - Because it's 2018 maan.
#     * Add DEFERRED_STRUCT_PAGE_INIT - Let's see what breaks.
#     * Add PPC_MEMTRACE - Small powernv debugfs driver for getting hardware traces.
#     * Add MEMORY_FAILURE - Machine check exceptions can now drive memory failure.
#     * Turn on FANOTIFY - This is the current filesystem notification feature.
#     * Turn on SCOM_DEBUGFS - Handy for hardware/firmware debugging, security risk?
#     * Turn on async SCSI scanning - Let's see what breaks.
#     * Add MLX5 driver as a module - Popular demand.
#     * Add CRYPTO_CRCT10DIF_VPMSUM - POWER8 T10DIF acceleration.
#     
#     * Make a bunch of USB hid drivers modules.
#     * Make SCSI SG, SR, and FC modules - FC is huge.
#     * Make video drivers except AST GPU modules - Also huge.
#     * Make PCI serial driver a module - Uncommon.
#     * Make more things modules, NFS FS, RAM disk, netconsole, MS-DOS fs.
#     
#     * Get rid of /dev/port - Not used.
#     * Remove PPS and PTP subsystms - Unusual.
#     * Remove legacy BSD ttys - Long dead.
#     * Remove IDE - Deprecated and replaced with ATA.
#     * Remove WIRELESS - Until we get POWER9 laptops.
#     * Remove RAW - Long deprecated in favour of direct IO.
#     * Remove floppy, parport, and PS2 input devices - not supported.
#     * Remove virtio drivers, ballooning - We're host only.
#     * Remove PPP - Sorry Paulus.
#     
#     This results in a significantly smaller vmlinux:
#     
#         text      data       bss        dec   filename
#     13143383   5277944   1317856   19739183   vanilla
#     12263281   4852074   1341720   18457075   patched
