[PATCH v1 0/5] uml: add more unspecified HAS_IOMEM dependencies

[Brendan Higgins]

# TL;DR

This patchset adds a missing HAS_IOMEM dependency to several drivers in
an attempt to get allyesconfig closer to working for ARCH=um. Although I
had caught all the broken ones in early 5.5[1], some new ones have
broken since then.

# What am I trying to do?

This patchset is part of my attempt to get `make ARCH=um allyesconfig`
to produce a config that will build *and* boot to init, so that I can
use it as a mechanism to run tests[2].

# Why won't allyesconfig break again after this series of fixes?

Well, in short, it will break again; however, as I mentioned above, I am
using UML for testing the kernel, and I am currently working on getting
my tests to run on KernelCI. As part of our testing procedure for
KernelCI, we are planning on building a UML kernel using allyesconfig
and running our tests on it. Thus, we will find out very quickly once
someone breaks allyesconfig again once we get this all working. So this
will keep breaking until we have a build test on KernelCI running, but
we will need to send out these fixes anyway.

[PATCH v1 1/5] net: axienet: add unspecified HAS_IOMEM dependency

[Brendan Higgins]

Currently CONFIG_XILINX_AXI_EMAC=y implicitly depends on
CONFIG_HAS_IOMEM=y; consequently, on architectures without IOMEM we get
the following build error:

/usr/bin/ld: drivers/net/ethernet/xilinx/xilinx_axienet_main.o: in function `axienet_probe':
drivers/net/ethernet/xilinx/xilinx_axienet_main.c:1680: undefined reference to `devm_ioremap_resource'
/usr/bin/ld: drivers/net/ethernet/xilinx/xilinx_axienet_main.c:1779: undefined reference to `devm_ioremap_resource'
/usr/bin/ld: drivers/net/ethernet/xilinx/xilinx_axienet_main.c:1789: undefined reference to `devm_ioremap_resource'

Fix the build error by adding the unspecified dependency.
