Remove messy dependencies from PARPORT_PC by having it depend on one
Kconfig symbol (ARCH_MAY_HAVE_PC_PARPORT) and having architectures
which need it, select ARCH_MAY_HAVE_PC_PARPORT in arch/*/Kconfig.
New architectures are unlikely to need PARPORT_PC, so this avoids
having an ever growing list of
Architectures which support CONFIG_PARPORT_PC should select
ARCH_MAY_HAVE_PC_PARPORT.

Hi Mark, Stephen and other DT maintainers?
The 1/3 had already been acked by Mark, and please have a further look
at this patch 2/3.
The DMA maintainer Vinod needs ack for the DT related patches so that
he can take all this patch set.

irq_exit() is now called on the irq stack, which can trigger a switch
to the softirq stack from the irq stack. If an interrupt happens at
that point, we will not properly detect the re-entrancy and clobber
the original return context on the irq stack.
This fixes it. The side effect is to prevent a

This help us to identify whether we are running with hypervisor mode KVM
enabled. The change is needed so that we can have both HV and PR kvm
enabled in the same kernel.
If both HV and PR KVM are included, interrupts come in to the HV version
of the kvmppc_interrupt code

Hi All,
This patch series support enabling HV and PR KVM together in the same kernel. We

KVM and "PR" PR KVM. If we don't specify kvm_type we will select the fastest
KVM mode.
