This patch fixes an bug revealed by the following commit:
6b89d4c1ae ("perf/x86/intel: Fix INTEL_FLAGS_EVENT_CONSTRAINT* masking")
That patch modified INTEL_FLAGS_EVENT_CONSTRAINT() to only look at the event code
when matching a constraint. If code+umask were needed, then the
INTEL_FLAGS_UEVENT_CONSTRAINT() macro was needed instead.
This broke with some of the constraints for PEBS events.
Several of them, including the one used for cycles:p, cycles:pp, cycles:ppp
fell in that category and caused the event to be rejected in PEBS mode.
In other words, on some platforms a cmdline such as:
$ perf top -e cycles:pp
would fail with -EINVAL.
This patch fixes this bug by properly using INTEL_FLAGS_UEVENT_CONSTRAINT()
when needed in the PEBS constraint tables.

As of today if userspace process tries to access a kernel virtual addres
(0x7000_0000 to 0x7ffff_ffff) such that a legit kernel mapping already
exists, that process hangs instead of being killed with SIGSEGV
Fix that by ensuring that do_page_fault() handles kenrel vaddr only if
in kernel mode.
And given this, we can also simplify the code a bit. Now a vmalloc fault
implies kernel mode so its failure (for some reason) can reuse the
@no_context label and we can remove @bad_area_nosemaphore.
Reproduce user test for original problem:

#include <stdlib.h>
#include <stdint.h>
int main(int argc, char *argv[])
{
volatile uint32_t temp;
temp = *(uint32_t *)(0x70000000);

Amlogic's vendor kernel defines an OPP for the GPU on Meson8b boards
with a voltage of 1.15V. It turns out that the vendor kernel relies on
the bootloader to set up the voltage. The bootloader however sets a
fixed voltage of 1.10V.
Amlogic's patched u-boot sources (uboot-2015-01-15-23a3562521) confirm
this:
$ grep -oiE "VDD(EE|AO)_VOLTAGE[ ]+[0-9]+" board/amlogic/configs/m8b_*
board/amlogic/configs/m8b_m100_v1.h:VDDAO_VOLTAGE 1100
board/amlogic/configs/m8b_m101_v1.h:VDDAO_VOLTAGE 1100
board/amlogic/configs/m8b_m102_v1.h:VDDAO_VOLTAGE 1100
board/amlogic/configs/m8b_m200_v1.h:VDDAO_VOLTAGE 1100
board/amlogic/configs/m8b_m201_v1.h:VDDEE_VOLTAGE 1100
board/amlogic/configs/m8b_m201_v1.h:VDDEE_VOLTAGE 1100
board/amlogic/configs/m8b_m202_v1.h:VDDEE_VOLTAGE 1100
Another hint at this is the VDDEE voltage on the EC-100 and Odroid-C1
boards. The VDDEE regulator supplies the Mali GPU. It's basically a copy
of the VCCK (CPU supply) which means it's limited to 0.86V to 1.14V.
Update the operating voltage of the Mali GPU on Meson8b to 1.10V so it
matches with what the vendor u-boot sets.

The interrupts in Amlogic's vendor kernel sources are all contiguous.
There are two typos leading to pp2 and pp4 as well as ppmmu2 and ppmmu4
incorrectly sharing the same interrupt line.
Fix this by using interrupt 170 for pp2 and 171 for ppmmu2.
Also drop the undocumented "switch-delay" which is a left-over from my
experiments with an early lima kernel driver when it was still
out-of-tree and required this property on Amlogic SoCs.

which is also used on the ARM models, builds on this driver's interface.
It is actually plaform independent: the OLPC EC commands with their argument
and responses are mostly the same despite the delivery mechanism is
