Merge branch 'arm/queue' into 'master'

arm/arm64: target-efi prep

This series mostly prepares kvm-unit-tests/arm for targeting EFI
platforms. The actually EFI support will come in another series,
but these patches are good for removing assumptions from our memory
maps and about our PSCI conduit, even if we never merge EFI support.

arm/arm64: mmu: Stop mapping an assumed IO region

By providing a proper ioremap function, we can just rely on devices
calling it for each region they need (as they already do) instead of
mapping a big assumed I/O range. We don't require the MMU to be
enabled at the time of the ioremap. In that case, we add the mapping
to the identity map anyway. This allows us to call setup_vm after
io_init. Why don't we just call setup_vm before io_init, I hear you
ask? Well, that's because tests like sieve want to start with the MMU
off, later call setup_vm, and all the while have working I/O. Some
unit tests are just really demanding...

While at it, ensure we map the I/O regions with XN (execute never),
as suggested by Alexandru Elisei.

arm: use absolute headers

Files in lib/arm including "asm/someheader.h" will get
lib/arm/asm/someheader.h, not lib/asm/someheader.h. So we
need to use <> instead of "" in order to prepare for headers
of the same name, but for a different arch. We change all
'#include's of all arm files, as consistency looks better.

Merge remote-tracking branch 'drjones/arm/v7-initial-drop'

arm: Add arch-specific asm/page.h and __va/__pa

These are pretty much the same as the asm-generic version,
but use phys_addr_t.

arm: initial drop

This is the initial drop of the arm test framework and a first test
that just checks that setup completed (a selftest). kvm isn't needed
to run this test unless testing with smp > 1.

Try it out with
yum install gcc-arm-linux-gnu
export QEMU=[qemu with mach-virt and chr-testdev]
./configure --cross-prefix=arm-linux-gnu- --arch=arm
make
./run_tests.sh

- fixed setup.c comment [Christoffer Dall]
- changed arm/run to use chr-testdev instead of virtio-testdev
- add align parameter to memregion_new, setup alloc_ops
v5:
- memregions: check freemem_start is in bounds and document
- selftest: rename testnam => testname and properly init it
- io.c: use writeb instead of writel in puts() and use ioremap
- arm/run script update for new qemu ('-device ?' now requires -machine)
- couple other minor changes to setup.c and io.c [Christoffer Dall]
