2016-03-22KVM/x86: update the comment of memory barrier in the vcpu_enter_guest()Lan Tianyu1-2/+6

2016-03-22KVM, pkeys: expose CPUID/CR4 to guestHuaitong Han4-6/+37
X86_FEATURE_PKU is referred to as "PKU" in the hardware documentation: CPUID.7.0.ECX[3]:PKU. X86_FEATURE_OSPKE is software support for pkeys, enumerated with CPUID.7.0.ECX[4]:OSPKE, and it reflects the setting of CR4.PKE(bit 22). This patch disables CPUID:PKU without ept, because pkeys is not yet implemented for shadow paging.

2016-03-22KVM, pkeys: add pkeys support for permission_faultHuaitong Han7-8/+72
Protection keys define a new 4-bit protection key field (PKEY) in bits 62:59 of leaf entries of the page tables, the PKEY is an index to PKRU register(16 domains), every domain has 2 bits(write disable bit, access disable bit). Static logic has been produced in update_pkru_bitmask, dynamic logic need read pkey from page table entries, get pkru value, and deduce the correct result.

2016-03-22KVM, pkeys: save/restore PKRU when guest/host switchesXiao Guangrong1-0/+23
Currently XSAVE state of host is not restored after VM-exit and PKRU is managed by XSAVE so the PKRU from guest is still controlling the memory access even if the CPU is running the code of host. This is not safe as KVM needs to access the memory of userspace (e,g QEMU) to do some emulation. So we save/restore PKRU when guest/host switches.

Pkeys is disabled if CPU is in non-paging mode in hardware. However KVM always uses paging mode to emulate guest non-paging, mode with TDP.

2016-03-22firewire: nosy: Replace timeval with timespec64Tina Ruchandani1-3/+5
'struct timeval' uses a 32 bit field for its 'seconds' value which will overflow in year 2038 and beyond. This patch replaces the use of timeval in nosy.c with timespec64 which doesn't suffer from y2038 issue. The code is correct as is - since it is only using the microseconds portion of timeval. However, this patch does the replacement as part of a larger effort to remove all instances of 'struct timeval' from the kernel (that would help identify cases where the code is actually broken).

2016-03-22KVM: PPC: Create a virtual-mode only TCE table handlersAlexey Kardashevskiy3-7/+57
Upcoming in-kernel VFIO acceleration needs different handling in real and virtual modes which makes it hard to support both modes in the same handler. This creates a copy of kvmppc_rm_h_stuff_tce and kvmppc_rm_h_put_tce in addition to the existing kvmppc_rm_h_put_tce_indirect. This also fixes linker breakage when only PR KVM was selected (leaving HV KVM off): the kvmppc_h_put_tce/kvmppc_h_stuff_tce functions would not compile at all and the linked would fail.
