2010-03-02sh: make pmb iomapping configurable.Paul Mundt
This plugs in an early_param for permitting transparent PMB-backed ioremapping to be enabled/disabled. For the time being, we use a default-disabled policy. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-03-02sh: reworked dynamic PMB mapping.Paul Mundt
This implements a fairly significant overhaul of the dynamic PMB mapping code. The primary change here is that the PMB gets its own VMA that follows the uncached mapping and we attempt to be a bit more intelligent with dynamic sizing, multi-entry mapping, and so forth. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-03-02sh: Fix up cpumask_of_pcibus() for the NUMA build.Paul Mundt
Trivial build fix, following the change from asm-generic/topology.h. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-03-02sh: Fix up ctrl_read/write stragglers in migor setup.Paul Mundt
ctrl_read/writeX are deprecated, this converts them over to their __raw_read/write() counterparts. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-03-02dmaengine: shdma: convert to platform device resourcesGuennadi Liakhovetski
The shdma dmaengine driver currently uses numerous macros to support various platforms, selected by ifdef's. Convert it to use platform device resources and lists of channel descriptors to specify register locations, interrupt numbers and other system-specific configuration variants. Unavoidably, we have to simultaneously convert all shdma users to provide those resources. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-03-01KVM: VMX: Update instruction length on intercepted BPJan Kiszka
We intercept #BP while in guest debugging mode. As VM exits due to intercepted exceptions do not necessarily come with valid idt_vectoring, we have to update event_exit_inst_len explicitly in such cases. At least in the absence of migration, this ensures that re-injections of #BP will find and use the correct instruction length.

2010-03-01KVM: Fix emulate_sys[call, enter, exit]()'s fault handlingTakuya Yoshikawa
This patch fixes emulate_syscall(), emulate_sysenter() and emulate_sysexit() to handle injected faults properly. Even though original code injects faults in these functions, we cannot handle these unless we use the different return value from the UNHANDLEABLE case. So this patch use X86EMUL_* codes instead of -1 and 0 and makes x86_emulate_insn() to handle these propagated faults. Be sure that, in x86_emulate_insn(), goto cannot_emulate and goto done with rc equals X86EMUL_UNHANDLEABLE have same effect.

2010-03-01KVM: Fix load_guest_segment_descriptor() to inject page faultTakuya Yoshikawa
This patch injects page fault when reading descriptor in load_guest_segment_descriptor() fails with FAULT. Effects of this injection: This function is used by kvm_load_segment_descriptor() which is necessary for the following instructions: - mov seg,r/m16 - jmp far - pop ?s This patch makes it possible to emulate the page faults generated by these instructions. But be sure that unless we change the kvm_load_segment_descriptor()'s ret value propagation this patch has no effect.
