lockdep: Avoid /proc/lockdep & lock_stat infinite output
Both /proc/lockdep and /proc/lock_stat output may loop infinitely.
When a read() requests an amount of data smaller than the amount of data
that the seq_file's foo_show() outputs, the output starts looping and
outputs the "stuck" element's data infinitely. There may be multiple
sequential calls to foo_start(), foo_next()/foo_show(), and foo_stop()
for a single open with sequential read of the file. The _start() does not
have to start with the 0th element and _show() might be called multiple
times in a row for the same element for a given open/read of the seq_file.
Also header output should not be happening in _start(). All output should
be in _show(), which SEQ_START_TOKEN is meant to help. Having output in
_start() may also negatively impact seq_file's seq_read() and traverse()
accounting.

x86: force timer broadcast on late AMD C1E detection
The 64bit SMP bootup is slightly different to the 32bit one. It enables
the boot CPU local APIC timer before all CPUs are brought up. Some AMD C1E
systems have the C1E feature flag only set in the secondary CPU. Due to
the early enable of the boot CPU local APIC timer the APIC timer is
registered as a fully functional device. When we detect the wreckage during
the bringup of the secondary CPU, we need to force the boot CPU into
broadcast mode.
Check the C1E caused APIC timer disable, when the secondary APIC timer is
initialized. If the boot CPU APIC timer was registered as a functional
clock event device, then fix this up and utilize the
CLOCK_EVT_NOTIFY_BROADCAST_FORCE mechanism to force the already
registered boot CPU APIC timer into broadcast mode.
Tested by force injecting the failure mode.

HID: add hidraw interface
hidraw is an interface that is going to obsolete hiddev one
day.
Many userland applications are using libusb instead of using
kernel-provided hiddev interface. This is caused by various
reasons - the HID parser in kernel doesn't handle all the
HID hardware on the planet properly, some devices might require
its own specific quirks/drivers, etc.
hiddev interface tries to do its best to parse all the received
reports properly, and presents only parsed usages into userspace.
This is however often not enough, and that's the reason why
many userland applications just don't use hiddev at all, and
rather use libusb to read raw USB events and process them on
their own.
Another drawback of hiddev is that it is USB-specific.
hidraw interface provides userspace readers with really raw HID
reports, no matter what the low-level transport layer is (USB/BT),
and gives the userland applications all the freedom to process
the HID reports in a way they wish to.

finish the operation and fail, which is not good. Moreover, if there

We were simply concatenating the devhandle and devino and using that

Now that we use physical addresses for the INO buckets, we can
allocate them dynamically for VIRQs and encode the cookies as
~__pa(bucket). This allows us to test for and decode the cookie with
a simple:
brlz $reg1, 1f
xnor $reg1, %g0, $reg2
sequence.
This works because bit 64 is never set in traditional
INO vectors, and it is also never set in a physical
address. So xnor'ing the physical address of the bucket
always gives us a negative number, and thus a unique
condition we can test cheaply.
