Once the Aksv is available in the PCH, we need to get it on the wire to
the receiver via DDC. The hardware doesn't allow us to read the value
directly, so we need to tell GMBUS to source the Aksv internally and
send it to the right offset on the receiver.
The way we do this is to initiate an index

Hi Chris,
Given commit

in Linus' tree, should I remove the tile tree from linux-next?
Yes, that would make sense. Good catch!

New kernel API allows creating [k,u]probe with perf_event_open.
This patch tries to use the new API. If the new API doesn't work,
we fall back to old API.
bpf_detach_probe() looks up the event being removed. If the event
is not found, we skip the clean up procedure.

perf_event.h is updated in previous patch, this patch applies same
changes to the tools/ version. This is part is put in a separate

Function load_and_attach() is updated to be able to create kprobes
with either old text based API, or the new perf_event_open API.
A global flag use_perf_kprobe is added to select between the two
APIs.

The test compares old text based kprobe API with perf_kprobe.
Here is a sample output of this test:
Creating 1000 kprobes with text-based API takes 6.979683 seconds
Cleaning 1000 kprobes with text-based API takes 84.897687 seconds
Creating 1000 kprobes with perf_kprobe (function name) takes 5.077
This patch adds perf_uprobe support with similar pattern as previous
patch (for kprobe).
Two functions, create_local_trace_uprobe() and
destroy_local_trace_uprobe(), are created so a uprobe can be created
and attached to the file descriptor created by perf_event_open().

Two new types kprobe and uprobe are being added to perf_event_open,
which allow creating kprobe or uprobe with perf_event_open. This

Two new perf types, perf_kprobe and perf_uprobe, will be added to allow
creating [k,u]probe with perf_event_open. These [k,u]probe are associated
with the file decriptor created by perf_event_open, thus are easy to
clean when the file descriptor is destroyed.
kprobe_func and uprobe_path are added
A new pmu, perf_kprobe is added. Based attr from perf_event_open(),
perf_kprobe creates a kprobe (or kretprobe) for the perf_event. This
kprobe is private to this perf_event, and thus not added to global
lists, and not available in tracefs.

If the kernel oopses while on the trampoline stack, it will say
"" even if SYSENTER is not involved. That is rather
confusing.
The "SYSENTER" stack is used for a lot more than SYSENTER now.

The refcount_t protection on x86 was not intended to use the stricter
GPL export. This adjusts the linkage again to avoid a regression in
the availability of the refcount API.

This part of Secure Encrypted Virtualization (SEV) patch series focuses on KVM

SEV is an extension to the AMD-V architecture which supports running encrypted

Define the SEV enable bit for the VMCB control structure. The hypervisor
will use this bit to enable SEV in the guest.
