This patch is useful when trying to pass a perf event to BPF map.
Before this patch we are unable to pass an event with config term to
BPF maps. For example:
# perf record -a -e cycles/no-inherit,period=0x7fff/ \

A new syntax is appended into parser so user can pass predefined perf
events into BPF objects.

bpf_perf_event_output() outputs data through sample->raw_data. This

then can be used to process output data from BPF programs.

When initing bad block list in gennvm_block_bb, once we move bad block
from free_list to bb_list, we should maintain both stat info
nr_free_blocks and nr_bad_blocks. So this patch fixes to add missing
operation related to nr_free_blocks.

Currently, panic() and crash_kexec() can be called at the same time.
For example (x86 case):
CPU 0:
oops_end()
crash_kexec()
mutex_trylock() // acquired
nmi_shootdown_cpus() // stop other CPUs
CPU 1:
panic()
crash_kexec()
mutex_trylock() //

Hi Ingo,
here's a pile which addresses issues which arise when using an NMI
button on certain platforms which provide it, to cause an external NMI
and thus cause a concurrent kdump to fail. For that, we're getting a
new cmdline option called "apic_extnmi" which can control
Hi,
Ping - almost three months passed.

kernel.panic_on_io_nmi sysctl was introduced by commit
5211a242d0cb ("x86: Add sysctl to allow panic on IOCK NMI error")
but its documentation is missing. So, add it.

This patch introduces a command line parameter apic_extnmi:
apic_extnmi=( bsp|all|none )
The default value is "bsp" and this is the current behavior: only the
Boot-Strapping Processor receives an external NMI.
"all" allows external NMIs to be broadcast to all CPUs. This
From: Hidehiro Kawai
If panic on NMI happens just after panic() on the same CPU, panic() is
recursively called. Kernel stalls, as a result, after failing to acquire
panic_lock.
To avoid this problem, don't call panic() in NMI context if we've
already entered panic().
For that, introduce
From: Hidehiro Kawai
Currently, kdump_nmi_shootdown_cpus(), a subroutine of crash_kexec(),
sends an NMI IPI to CPUs which haven't called panic() to stop them,
save their register information and do some cleanups for crash dumping.
However, if such a CPU is infinitely looping in NMI context, we

Now, multiple CPUs can receive an external NMI simultaneously by
specifying the "apic_extnmi=all" command line parameter. When we take
a crash dump by using external NMI with this option, we fail to save
registers into the crash dump. This happens as follows:

I am announcing the release of the Linux 3.16.7-ckt21 kernel.
The updated 3.16.y-ckt tree can be found at:
git://kernel.ubuntu.com/ubuntu/linux.git linux-3.16.y
and can be browsed at:
http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y
The diff from v3.16.7-ckt20 is posted
Add device tree bindings to support specifying outputs from the chip as
mono outputs. Whilst we are doing it change the out_mono pdata from a
bool to an int, because Sparse gets upset about using ARRAY_SIZE on
bools.

Update the device tree binding documentation to include the wlf,out-mono
property that is used to specify whether each output is a mono or stereo
output.

Changes since v1:
- Clarify which outputs correspond to which entry in the out-mono list.
Thanks,
