Fix kprobe-tracer not to delete a probe if the probe is in use.
In that case, delete operation will return -EBUSY.
This bug can cause a kernel panic if enabled probes are deleted
during perf record.
(Add some probes on functions)
sh-4.2# perf probe --del probe:\*
sh-4.2# exit
(kernel panic)
This is originally reported on the fedora bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=742383
I've also checked that this problem doesn't happen on
tracepoints when module removing because perf event
locks target module.
$ sudo ./perf record -e xfs:\* -aR sh

ERROR: Module xfs is in use

Due to the 16 bit access to mscan registers there's too much data copied to
the zero initialized CAN frame when having an odd number of bytes to copy.
This patch ensures that only the requested bytes are copied by using an
8 bit access for the remaining byte.

The doorbell register was being unconditionally swapped. In x86, that
meant it was being swapped to BE and written to the descriptor and to
memory, depending on the case of blue frame support or writing to
doorbell register. On PPC, this meant it was being swapped to LE and
then swapped back to BE while writing to the register. But in the blue
frame case, it was being written as LE to the descriptor.
The fix is not to swap doorbell unconditionally, write it to the
register as BE and convert it to BE when writing it to the descriptor.

We only really need the defaults in order to cut down the number of
registers we sync and to satisfy reads while the device is powered off
but not all devices are going to need to do that (always on devices like
PMICs being the prime example) so don't require those devices to supply
a default. Instead only try to fall back to hardware defaults if the
driver told us to.
Devices using LZO won't be able to instantiate with this, that will require
some updates in the LZO code to handle this case.

Simplify the check for registers set at their default value by avoiding
picking a default value in the case where we don't have one. Instead we
only compare the current value to the current value when we looked one
up. This fixes the case where we don't have a default stored but the value
was set to zero when that isn't the chip default.

Previous patches allow the NMI subsystem to process multipe NMI events
in one NMI. As previously discussed this can cause issues when an event
triggered another NMI but is processed in the current NMI. This causes the
next NMI to go unprocessed and become an 'unknown' NMI.
To handle this, we first have to flag whether or not the NMI handler handled
more than one event or not. If it did, then there exists a chance that
the next NMI might be already processed. Once the NMI is flagged as a
candidate to be swallowed, we next look for a back-to-back NMI condition.
This is determined by looking at the %rip from pt_regs. If it is the same
as the previous NMI, it is assumed the cpu did not have a chance to jump
back into a non-NMI context and execute code and instead handled another NMI.
If both of those conditions are true then we will swallow any unknown NMI.
There still exists a chance that we accidentally swallow a real unknown NMI,
but for now things seem better.
An optimization has also been added to the nmi notifier rountine. Because x86
can latch up to one NMI while currently processing an NMI, we don't have to
worry about executing _all_ the handlers in a standalone NMI. The idea is
if multiple NMIs come in, the second NMI will represent them. For those
back-to-back NMI cases, we have the potentail to drop NMIs. Therefore only
execute all the handlers in the second half of a detected back-to-back NMI.

Just convert all the files that have an nmi handler to the new routines.
Most of it is straight forward conversion. A couple of places needed some
tweaking like kgdb which separates the debug notifier from the nmi handler
and mce removes a call to notify_die.
[Thanks to Ying for finding out the history behind that mce call
https://lkml.org/lkml/2010/5/27/114
And Boris responding that he would like to remove that call because of it
https://lkml.org/lkml/2011/9/21/163]
The things that get converted are the registeration/unregistration routines
and the nmi handler itself has its args changed along with code removal
to check which list it is on (most are on one NMI list except for kgdb
which has both an NMI routine and an NMI Unknown routine).

The NMI handlers used to rely on the notifier infrastructure. This worked
great until we wanted to support handling multiple events better.
One of the key ideas to the nmi handling is to process _all_ the handlers for
each NMI. The reason behind this switch is because NMIs are edge triggered.
If enough NMIs are triggered, then they could be lost because the cpu can
only latch at most one NMI (besides the one currently being processed).
In order to deal with this we have decided to process all the NMI handlers
for each NMI. This allows the handlers to determine if they recieved an
event or not (the ones that can not determine this will be left to fend
for themselves on the unknown NMI list).
As a result of this change it is now possible to have an extra NMI that
was destined to be received for an already processed event. Because the
event was processed in the previous NMI, this NMI gets dropped and becomes
an 'unknown' NMI. This of course will cause printks that scare people.
However, we prefer to have extra NMIs as opposed to losing NMIs and as such
are have developed a basic mechanism to catch most of them. That will be
a later patch.
To accomplish this idea, I unhooked the nmi handlers from the notifier
routines and created a new mechanism loosely based on doIRQ. The reason
for this is the notifier routines have a couple of shortcomings. One we
could't guarantee all future NMI handlers used NOTIFY_OK instead of
NOTIFY_STOP. Second, we couldn't keep track of the number of events being
handled in each routine (most only handle one, perf can handle more than one).
Third, I wanted to eventually display which nmi handlers are registered in
the system in /proc/interrupts to help see who is generating NMIs.
The patch below just implements the new infrastructure but doesn't wire it up
yet (that is the next patch). Its design is based on doIRQ structs and the
atomic notifier routines. So the rcu stuff in the patch isn't entirely untested
(as the notifier routines have soaked it) but it should be double checked in
case I copied the code wrong.

Intel does not have guest/host-only bit in perf counters like AMD
does. To support GO/HO bits KVM needs to switch EVENTSELn values
(or PERF_GLOBAL_CTRL if available) at a guest entry. If a counter is
configured to count only in a guest mode it stays disabled in a host,
but VMX is configured to switch it to enabled value during guest entry.
This patch adds GO/HO tracking to Intel perf code and provides interface
for KVM to get a list of MSRs that need to be switched on a guest entry.
Only cpus with architectural PMU (v1 or later) are supported with this
patch. To my knowledge there is not p6 models with VMX but without
architectural PMU and p4 with VMX are rare and the interface is general
enough to support them if need arise.

A couple of changes to the Tegra maintainership setup:
I'm very glad to bring on Stephen Warren on board as a maintainer. The
work he has done so far is excellent, and the fact that he works for
Nvidia means he has long-term interest in the platform.
Erik Gilling did an astounding amount of work on getting things up and
running but has been a silent partner on the maintainership side for a
while, and is stepping down. Thanks for your contributions so far, Erik.
Finally, update the git URL since I'll take over running the main repo
for a while.
Overall maintainership model isn't changing much at this time: We'll all
three review patches as appropriate, and one of us will collect the main
repo (me at this time).
