* kernel: enable FUTEX_PI by defaultSergey Ryazanov2018-05-221-1/+0
| | | | | | | | | New FUTEX_PI configuration symbol enabled if FUTEX and RT_MUTEX symbols are enabled. Both of these symbols are enabled by default in the generic config, so enable FUTEX_PI by default too to keep platform specific configs minimal.

* kernel: enable EXPORTFS by defaultSergey Ryazanov2018-05-221-1/+0
| | | | | | | | OVERLAY_FS config symbol selects EXPORTFS since 4.12 kernel, we have OVERLAY_FS enabled by default, so enable EXPORTFS in the generic config of 4.14 and remove this option from platform specific configs. Signed-off-by: Sergey Ryazanov <ryazanov.s.a@gmail.com>
* kernel: disable DRM_LIB_RANDOM by defaultSergey Ryazanov2018-05-221-1/+0
| | | | | | | DRM_LIB_RANDOM config symbol selected only by DRM_DEBUG_MM_SELFTEST which is disable by default, so disable DRM_LIB_RANDOM by default too. Signed-off-by: Sergey Ryazanov <ryazanov.s.a@gmail.com>
* kernel: disable DMA_{NOOP|VIRT}_OPS by defaultSergey Ryazanov2018-05-221-2/+0
| | | | | | | These options do not used by any supported arch, so disable them by default to make arch configs a bit more clean. Signed-off-by: Sergey Ryazanov <ryazanov.s.a@gmail.com>
* kernel: disable ARCH_WANTS_THP_SWAP by defaultSergey Ryazanov2018-05-221-1/+0
| | | | | | | | Only one arch (x86_64) enables this option. So disable ARCH_WANTS_THP_SWAP by default and remove referencies to it from all configs (except x86_64) to make them clean. Signed-off-by: Sergey Ryazanov <ryazanov.s.a@gmail.com>

| | | | | | | | You should not define CFLAGS for the toolchain as this will also leak into other targets if they share the same toolchain. Cc: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: Tim Harvey <tharvey@gateworks.com>
* octeontx: add FAT FS support to kernelTim Harvey2018-02-221-0/+2

* octeontx: add support for OCTEON TX targetTim Harvey2018-02-138-0/+1049
The Cavium OCTEON TX is an ARM 64-bit SoC leveraging CPU cores and periperhals from the Cavium ThunderX SoC. This initial support provides a 4.14 kernel and kernel+initramfs that is bootable on the Gateworks Newport GW630x as well as the Cavium sff8104 reference board.
