commit a55749639dc1 ("ia64: drop marked broken DISCONTIGMEM and
VIRTUAL_MEM_MAP")
drop VIRTUAL_MEM_MAP, so there is no need HOLES_IN_ZONE on ia64.
Also move HOLES_IN_ZONE into mm/Kconfig, select it if architecture needs
this feature.

When add RISCV arch to huawei build test, there are some build
issue, let's fix them to make riscv build happier :)
Those patches is rebased on next-20200508.
Kefeng Wang (10):
riscv: Fix unmet direct dependencies built based on SOC_VIRT
riscv: stacktrace: Fix undefined reference
Some drivers use PAGE_SHARED, pgprot_writecombine()/pgprot_device(),
add the defination to fix build error if NOMMU.

As discussion in
https://lore.kernel.org/lkml/20191129222310.ga3712...@kroah.com/,
we could introduce a new helper macro to reduce losts of boilerplate
code, vmstat and kprobes is the example which covert to use it, if
this is accepted, I will send out more clean ups.
