Sudip Mukherjee 1a5e251996 Input: serio - fix blocking of parport 
If parkbd_allocate_serio() fails to allocate memory we are releasing the
parport but we missed unregistering the device. As a result this device
with exclusive access to that parport remains registered. And no other
device will be able to use that parport even though this driver has
failed to load.

Paul Burton e060f6ed28 MIPS: Initialise MAARs on secondary CPUs 
MAARs should be initialised on each CPU (or rather, core) in the system
in order to achieve consistent behaviour & performance. Previously they
have only been initialised on the boot CPU which leads to performance
problems if tasks are later scheduled on a secondary CPU, particularly
if those tasks make use of unaligned vector accesses where some CPUs
don't handle any cases in hardware for non-speculative memory regions.
Fix this by recording the MAAR configuration from the boot CPU and
applying it to secondary CPUs as part of their bringup.

Paul Burton def3ab5d0a MIPS: mm: compile maar_init unconditionally 
maar_init was previously only compiled when CONFIG_NEED_MULTIPLE_NODES
was not set, which has been fine since it is only called from the
standard implementation of mem_init which has the same condition. In
preparation for calling it from the SMP startup code on secondary CPUs,
move maar_init outside of the #ifndef such that it is always compiled.

Paul Burton d77d5ac9c9 irqchip: mips-gic: Fix pending & mask reads for MIPS64 with 32b GIC. 
gic_handle_shared_int reads the GIC interrupt pending & mask registers
directly into a bitmap, which is defined as an array of unsigned longs.
The GIC pending registers may be 32 bits wide if the CM is older than
CM3, regardless of the bit width of the CPU, but for MIPS64 kernels
the unsigned longs in the bitmap will be 64 bits wide. In this case we
need to perform 2 x 32 bit reads per 64 bit unsigned long in order to
avoid missing interrupts.

Paul Burton 7573b94e08 MIPS: CM: Provide a function to map from CPU to VP ID. 
The VP ID of a given CPU may not match up with the CPU number used by
Linux. For example, if the width of the VP part of the VP ID is wider
than log2(number of VPs per core) and the system has multiple cores then
this will be the case. Alternatively, if a pre-r6 system implements the
MT ASE with multiple VPEs per core and Linux is built without support
for the MT ASE then the numbers won't match up either. Provide a
function to convert from CPU number to VP ID.

Len Brown a2b7b74945 tools/power turbostat: SKL: Adjust for TSC difference from base frequency 
On a Skylake with 1500MHz base frequency,
the TSC runs at 1512MHz.

This is because the TSC is no longer in the n*100 MHz BCLK domain,
but is now in the m*24MHz crystal clock domain. (24 MHz * 63 = 1512 MHz)

This adds error to several calculations in turbostat,
unless the TSC sample sizes are adjusted for this difference.

Note that calculations in the time domain are immune
from this issue, as the timing sub-system has already
calibrated the TSC against a known wall clock.

AVG_MHz = APERF_delta/measurement_interval

	need no adjustment.  APERF_delta is in the BCLK domain,
	and measurement_interval is in the time domain.

TSC_MHz  =  TSC_delta/measurement_interval

	needs no adjustment -- as we really do want to report
	the actual measured TSC delta here, and measurement_interval
	is in the accurate time domain.

%Busy = MPERF_delta/TSC_delta

	needs adjustment to use TSC_BCLK_DOMAIN_delta.
	TSC_BCLK_DOMAIN_delta = TSC_delta * base_hz / tsc_hz

Bzy_MHz = TSC_delta/APERF_delta/MPERF_delta/measurement_interval

	need adjustment as above.

No other metrics in turbostat need to be adjusted.

Before:

     CPU Avg_MHz   %Busy Bzy_MHz TSC_MHz
       -     550   24.84    2216    1512
       0    2191   98.73    2219    1514
       2       0    0.01    2130    1512
       1       9    0.43    2016    1512
       3       2    0.08    2016    1512

After:

     CPU Avg_MHz   %Busy Bzy_MHz TSC_MHz
       -     550   25.05    2198    1512
       0    2190   99.62    2199    1512
       2       0    0.01    2152    1512
       1       9    0.46    2000    1512
       3       2    0.10    2000    1512

Note that in this example, the "Before" Bzy_MHz
was reported as exceeding the 2200 max turbo rate.
Also, even a pinned spin loop would not be reported
as over 99% busy.

Hubert Chrzaniuk b2b34dfe4d tools/power turbostat: KNL workaround for %Busy and Avg_MHz 
KNL increments APERF and MPERF every 1024 clocks.
This is compliant with the architecture specification,
which requires that only the ratio of APERF/MPERF need be valid.

However, turbostat takes advantage of the fact that these
two MSRs increment every un-halted clock
at the actual and base frequency:

AVG_MHz = APERF_delta/measurement_interval

%Busy = MPERF_delta/TSC_delta

This quirk is needed for these calculations to also work on KNL,
which would otherwise show a value 1024x smaller than expected.

commit 6fb3143b56 ("tools/power turbostat: dump CONFIG_TDP")
touches MSR 0x648, which is not supported on IVB-Xeon.
This results in "turbostat --debug" exiting on those systems:

Remove IVB-Xeon from the list of machines supporting with that MSR.

Prior to the VRF change the oif was not set in the flow struct, so the
VRF support should really have only added the vrf_master_ifindex lookup.

Doug Ledford 2866196f29 IB/ipoib: increase the max mcast backlog queue 
When performing sendonly joins, we queue the packets that trigger
the join until the join completes.  This may take on the order of
hundreds of milliseconds.  It is easy to have many more than three
packets come in during that time.  Expand the maximum queue depth
in order to try and prevent dropped packets during the time it
takes to join the multicast group.

Jiang Liu 5ebc760353 ACPI, PCI, irq: Do not share PCI IRQ with ISA IRQ 
Avoid IRQs occupied by ISA IRQs when allocating IRQs for PCI link devices,
otherwise it may cause interrupt storm due to incompatible pin attributes.

This issue was triggered on a KVM virtual machine, which
 1) uses IRQ9 for SCI in high level mode.
 2) defines an PCI interrupt link device (LNKS) with IRQ9 as the only
    possible irq.
 3) has an PCI device referring to link device LNKS.
So it causes interrupt storm when enabling the PCI device because PCI IRQ
works in low level mode.
