2008-10-15MIPS: IP22/28: Switch over to RTC class driverThomas Bogendoerfer
This patchset removes some dead code and creates a platform device for the RTC class driver. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-10-15MIPS: PCI: Scan busses when they are registeredAurelien Jarno
The patch below changes register_pci_controller() such that controllers being added after pcibios_init() has run are be scanned immediately. This is needed for example by the BCM47xx PCI controller, which is located on the SSB bus, which is now initialized after the PCI subsystem.

2008-10-15KVM: x86 emulator: Use DstAcc for 'and'Guillaume Thouvenin
For instruction 'and al,imm' we use DstAcc instead of doing the emulation directly into the instruction's opcode. Signed-off-by: Guillaume Thouvenin <guillaume.thouvenin@ext.bull.net> Signed-off-by: Avi Kivity <avi@qumranet.com>
2008-10-15KVM: x86 emulator: Add cmp al, imm and cmp ax, imm instructions (ocodes 3c, 3d)Guillaume Thouvenin
Add decode entries for these opcodes; execution is already implemented. Signed-off-by: Guillaume Thouvenin <guillaume.thouvenin@ext.bull.net> Signed-off-by: Avi Kivity <avi@qumranet.com>
2008-10-15KVM: x86 emulator: Add DstAcc operand typeGuillaume Thouvenin
Add DstAcc operand type. That means that there are 4 bits now for DstMask. "In the good old days cpus would have only one register that was able to fully participate in arithmetic operations, typically called A for Accumulator. The x86 retains this tradition by having special, shorter encodings for the A register (like the cmp opcode), and even some instructions that only operate on A (like mul). SrcAcc and DstAcc would accommodate these instructions by decoding A into the corresponding 'struct operand'." -- Avi Kivity Signed-off-by: Guillaume Thouvenin <guillaume.thouvenin@ext.bull.net> Signed-off-by: Avi Kivity <avi@qumranet.com>

2008-10-15KVM: x86 emulator: fix jmp r/m64 instructionAvi Kivity
jmp r/m64 doesn't require the rex.w prefix to indicate the operand size is 64 bits. Set the Stack attribute (even though it doesn't involve the stack, really) to indicate this. Signed-off-by: Avi Kivity <avi@qumranet.com>

2008-10-15KVM: x86: unhalt vcpu0 on resetMarcelo Tosatti
Since "KVM: x86: do not execute halted vcpus", HLT by vcpu0 before system reset by the IO thread will hang the guest. Mark vcpu as runnable in such case. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@qumranet.com>

2008-10-15KVM: x86: do not execute halted vcpusMarcelo Tosatti
Offline or uninitialized vcpu's can be executed if requested to perform userspace work. Follow Avi's suggestion to handle halted vcpu's in the main loop, simplifying kvm_emulate_halt(). Introduce a new vcpu->requests bit to indicate events that promote state from halted to running. Also standardize vcpu wake sites.

2008-10-15KVM: x86 emulator: Add in/out instructions (opcodes 0xe4-0xe7, 0xec-0xef)Mohammed Gamal

2008-10-15KVM: MMU: Modify kvm_shadow_walk.entry to accept u64 addrSheng Yang
EPT is 4 level by default in 32pae(48 bits), but the addr parameter of kvm_shadow_walk->entry() only accept unsigned long as virtual address, which is 32bit in 32pae. This result in SHADOW_PT_INDEX() overflow when try to fetch level 4 index. Fix it by extend kvm_shadow_walk->entry() to accept 64bit addr in parameter.

2008-10-15KVM: s390: Make facility bits future-proofChristian Borntraeger

2008-10-15KVM: add MC5_MISC msr read supportJoerg Roedel

No memory is protected anyway. Signed-off-by: Avi Kivity <avi@qumranet.com>
2008-10-15KVM: MMU: Fix setting the accessed bit on non-speculative sptesAvi Kivity
The accessed bit was accidentally turned on in a random flag word, rather than, the spte itself, which was lucky, since it used the non-EPT compatible PT_ACCESSED_MASK. Fix by turning the bit on in the spte and changing it to use the portable accessed mask. Signed-off-by: Avi Kivity <avi@qumranet.com>
2008-10-15KVM: MMU: Flush tlbs after clearing write permission when accessing dirty logAvi Kivity
Otherwise, the cpu may allow writes to the tracked pages, and we lose some display bits or fail to migrate correctly. Signed-off-by: Avi Kivity <avi@qumranet.com>
2008-10-15KVM: MMU: Add locking around kvm_mmu_slot_remove_write_access()Avi Kivity

2008-10-15KVM: Don't call get_user_pages(.force = 1)Avi Kivity
