Hi Jonas,
I noticed your patch 'regmap: make LZO cache optional' as it recently showed up
in linux-next. In your patch, you modify drivers/base/regmap/regcache.c by
adding an #if IS_ENABLED() statement.
However, this statement contains a spelling error, as it references
REGCHACHE_COMPRESSED inste

Hi,
I've got the following error report while fuzzing the kernel with syzkaller.
On commit b29794ec95c6856b316c2295904208bf11ffddd9 (4.12-rc4+).
INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.

Looks correct, though I wonder whether it would be nicer to move the

With this patch set I continue the effort of upstreaming the eznps platform for
arch/arc.
It comprise of couple of patches from last set yet not accepted,
patches for HW erratas and some misc extensions such for HIGHMEM / NUMA.
This set got more generic ARC changes than previo

This patch is derived due to performance issue.
The use case is a page fault that resides on more than the local cpu.
Trying to broadcast all CPUs results on performance degradation.
So we try to avoid this by sending only to the relevant CPUs.

This is needed for NPS400 where high memory is assigned to node1
where the associated addresses are lower than node0.
This use case is not typical and just using discontigmem is not enough
since nodes assumed to have increasing address range.
i.e. address range of node0 assumed t

This way FIXMAP can have 2 PTEs per CPU even for
NR_CPUS=4096
For the extreme case like in eznps platform We use
all gutter between kernel and user.

Now it is used for NPS SoC for multi-core of 256 cores
and SMT of 16 HW threads per core.
This way with topology the scheduler is much efficient in
creating domains and later using them.

The following commit adds a config that will enable us to distinguish
between building the kernel for platforms that have a different set
of auxiliary registers for each cpu and platforms that have a shared
set of auxiliary registers across every thread in each core.

Working with NPS400 we noticed that there is a possibility of L1
interrupt nesting that may run out kernel stack.
The scenario include serving invoke_softirqs() from irq_exit()

managed to restore last one and pop so

GPA1 is used for compare value, and EFLAGS got bit reflects

EFLAGS is zeroed for each new user task so it won't get its

The reasons are:
1) speeding up boot time, becomes critical for many CPUs machine,
e.g. NPS400 with 4K CPUs
2) shorten kernel log at boot time, again easy to scan for large
