The planned move of include/asm-s390 to arch/s390/include/asm
requires that all includes for asm headers use include/asm and
not include/asm-s390.

Since git commit 3da1c84c00
"workqueues: make get_online_cpus() useable for work->func()"
it is safe to call get_online_cpus() from workqueue context.
So remove the kthread workaround again.

Fix these two false positive warnings:
WARNING: vmlinux.o(.text+0x2e1cc4): Section mismatch in reference from the function s390_virtio_console_init() to the function .init.text:early_put_chars()
The function s390_virtio_console_init() references
the function __init early_put_chars().
This is often because s390_virtio_console_init lacks a __init
annotation or the annotation of early_put_chars is wrong.
WARNING: vmlinux.o(.text+0x2e1cd0): Section mismatch in reference from the function s390_virtio_console_init() to the function .init.text:virtio_cons_early_init()

Fix the two section mismatch warnings below.
This fixes two real bugs since the code which has __exit annotations
may already be gone when it is called.
WARNING: vmlinux.o(.init.text+0x1cc4a): Section mismatch in reference from the function init_QDIO() to the function .exit.text:qdio_setup_exit()
The function __init init_QDIO() references
a function __exit qdio_setup_exit().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __exit annotation of
qdio_setup_exit() so it may be used outside an exit section.
WARNING: vmlinux.o(.init.text+0x1cc7a): Section mismatch in reference from the function init_QDIO() to the function .exit.text:qdio_remove_perf_stats()
The function __init init_QDIO() references
a function __exit qdio_remove_perf_stats().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __exit annotation of
qdio_remove_perf_stats() so it may be used outside an exit section.

sclp_sync_wait wait synchronously for an sclp interrupt and disables
timer interrupts. However on the irq enter paths there is an extra
check if a timer interrupt would be due and calls the timer callback.
This would schedule softirqs in the wrong context.
So introduce local_tick_enable/disable which prevents this.

When z/VM provides two virtual devices (minidisks) that reside on the
same real device, both will receive the configuration data from the
real device and thus get the same uid. To fix this problem, z/VM
provides an additional configuration data record that allows to
distinguish between minidisks.
z/VM APAR VM64273 needs be installed so this fix has an effect.

Cornelia Huck noticed that a modular virtio without kvm guest support
leads to a build error in the s390 virtio transport:
CONFIG_VIRTIO=m leads to
ERROR: "vmem_add_mapping" [drivers/s390/kvm/kvm_virtio.ko] undefined!
ERROR: "max_pfn" [drivers/s390/kvm/kvm_virtio.ko] undefined!
ERROR: "vmem_remove_mapping" [drivers/s390/kvm/kvm_virtio.ko] undefined!
The virtio transport only works with kvm guest support and only as a
builtin. Lets change the build process of drivers/s390/kvm/kvm_virtio.c
to depend on kvm guest support, which is also a bool.
CONFIG_S390_GUEST already selects CONFIG_VIRTIO, that should prevent
CONFIG_S390_GUEST=y CONFIG_VIRTIO=n situations.

To prepare for virtio_ring transport feature bits, hook in a call in
all the users to manipulate them. This currently just clears all the
bits, since it doesn't understand any features.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Rather than explicitly handing the features to the lower-level, we just
hand the virtio_device and have it set the features. This make it clear
that it has the chance to manipulate the features of the device at this
point (and that all feature negotiation is already done).
