->getattr() is now passed a struct path rather than a vfsmount and

4.104 KVM_X86_GET_MCE_CAP_SUPPORTED
Capability: KVM_CAP_MCE
Architectures: x86
Type: system ioctl
Parameters: u64 mce_cap (out)
Returns: 0 on success, -1 on error
Returns supported MCE capabilities. The u64 mce_cap parameter
has the same format as the MSR_IA32_MCG_CAP register. Supported
capabilities will have the corresponding bits set.
4.105 KVM_X86_SETUP_MCE
Capability: KVM_CAP_MCE
Architectures: x86
Type: vcpu ioctl
Parameters: u64 mcg_cap (in)
Returns: 0 on success,
-EFAULT if u64 mcg_cap cannot be read,
-EINVAL if the requested number of banks is invalid,
-EINVAL if requested MCE capability is not supported.
Initializes MCE support for use. The u64 mcg_cap parameter
has the same format as the MSR_IA32_MCG_CAP register and
specifies which capabilities should be enabled. The maximum
supported number of error-reporting banks can be retrieved when
checking for KVM_CAP_MCE. The supported capabilities can be
retrieved with KVM_X86_GET_MCE_CAP_SUPPORTED.
4.106 KVM_X86_SET_MCE
Capability: KVM_CAP_MCE
Architectures: x86
Type: vcpu ioctl
Parameters: struct kvm_x86_mce (in)
Returns: 0 on success,
-EFAULT if struct kvm_x86_mce cannot be read,
-EINVAL if the bank number is invalid,
-EINVAL if VAL bit is not set in status field.
Inject a machine check error (MCE) into the guest. The input
parameter is:
struct kvm_x86_mce {
__u64 status;
__u64 addr;
__u64 misc;
__u64 mcg_status;
__u8 bank;
__u8 pad1[7];
__u64 pad2[3];
};
If the MCE being reported is an uncorrected error, KVM will
inject it as an MCE exception into the guest. If the guest
MCG_STATUS register reports that an MCE is in progress, KVM
causes an KVM_EXIT_SHUTDOWN vmexit.
Otherwise, if the MCE is a corrected error, KVM will just
store it in the corresponding bank (provided this bank is
not holding a previously reported uncorrected error).

Bits for undefined preemption levels are RAZ/WI.
For historical reasons and to provide ABI compatibility with userspace we
export the GICC_PMR register in the format of the GICH_VMCR.VMPriMask
field in the lower 5 bits of a word, meaning that userspace must always
use the lower 5 bits to communicate with the KVM device and must shift the
value left by 3 places to obtain the actual priority mask level.
Limitations:
- Priorities are not implemented, and registers are RAZ/WI
- Currently only implemented for KVM_DEV_TYPE_ARM_VGIC_V2.

* unsigned long pa_memcpy(void *dstp, const void *srcp, unsigned long len)
*
* Inputs:
* - sr1 already contains space of source region
* - sr2 already contains space of destination region
*
* Returns:
* - number of bytes that could not be copied.
* On success, this will be zero.
*
* This code is based on a C-implementation of a copy routine written by
* Randolph Chung, which in turn was derived from the glibc.
*
* Several strategies are tried to try to get the best performance for various
* conditions. In the optimal case, we copy by loops that copy 32- or 16-bytes
* at a time using general registers. Unaligned copies are handled either by
* aligning the destination and then using shift-and-write method, or in a few
* cases by falling back to a byte-at-a-time copy.
*
* Testing with various alignments and buffer sizes shows that this code is
* often >10x faster than a simple byte-at-a-time copy, even for strangely
* aligned operands. It is interesting to note that the glibc version of memcpy
* (written in C) is actually quite fast already. This routine is able to beat
* it by 30-40% for aligned copies because of the loop unrolling, but in some
* cases the glibc version is still slightly faster. This lends more
* credibility that gcc can generate very good code as long as we are careful.
*
* Possible optimizations:
* - add cache prefetching
* - try not to use the post-increment address modifiers; they may create
* additional interlocks. Assumption is that those were only efficient on old
* machines (pre PA8000 processors)
