[RFC 1/6] ARC: regenerate nSIM and HAPS defconfigs

[RFC 4/6] ARC: HAPS: add HIGHMEM memory zone to DTS

This is required as a preparation of merging nSIM and HASP defonfig and device tree. As we have HIGHMEM disabled in both HAPS and nSIM defconfigs this doesn't lead to any functional change. Signed-off-by: Eugeniy Paltsev --- arch/arc/boot/dts/haps_hs.dts | 13 - 1 file changed, 8 in

[RFC 5/6] ARC: HAPS: cleanup defconfigs from unused ETH drivers

We have multiple vendors ethernet drivers enabled in haps_hs and haps_hs_smp defconfig. The only one we possibly require is VIRTIO_NET. So disable unused ones via disabling entire CONFIG_ETHERNET which controls all vendor-specific ethernet drivers. Signed-off-by: Eugeniy Paltsev --- arch/arc/con

[RFC 3/6] ARC: HAPS: use same UART configuration everywhere

For some reason we use ns8250 UART compatible on UP HAPS configuration and ns16550a (which is ns8250 with FIFO support) on SMP HAPS configuration. Given that we have same UART IP with same IP configuration on both HAPS configuration use ns16550a compatible everywhere. Signed-off-by: Eugeniy Paltse

[RFC 2/6] ARC: HAPS: cleanup defconfigs from unused IO-related options

We don't have any peripherals on HAPS which may require FB or input_devices support. So get rid of them. Signed-off-by: Eugeniy Paltsev --- arch/arc/configs/haps_hs_defconfig | 9 +++-- arch/arc/configs/haps_hs_smp_defconfig | 9 +++-- 2 files changed, 6 insertions(+), 12 deletions(-

[RFC 0/6] ARC: merge HAPS-HS with nSIM-HS configs

Starting from nSIM 2019.06 is possible to use DW UART instead of ARC UART. That allows us to merge "nsim_hs" with "haps_hs" and "nsim_hs_smp" with "haps_hs_smp" mith some minor changes. We eliminate nsim_hs_defconfig and nsim_hs_smp_defconfig and leave haps_hs_defconfig and haps_hs_smp_defconfig w

[PATCH v12 02/22] arc: mm: Add p?d_leaf() definitions

walk_page_range() is going to be allowed to walk page tables other than those of user space. For this it needs to know when it has reached a 'leaf' entry in the page tables. This information will be provided by the p?d_leaf() functions/macros. For arc, we only have two levels, so only pmd_leaf() i
