The regression caused by the commit cf39bf58afdaabc0b ("printk: fix

Especially the logic around the preferred console was somehow
twisted. The first two patches tr
More consoles can be registered but one might be special. It is the one
with CON_CONSDEV flag set. It must be the first in the console_drivers
list. It is also sometimes called as a preferred one.
It is the console that is associated with /dev/console. It is shown
by "showconsole" binary. But if n
register_console() has a fallback code that enables the first

is really tangled by the variable "has_preferred"
The only purpose of the variable is to decide whether we use the fallback
code or not. It is set when the console setup s
It is superfluous to set "has_preferred" when the really preferred
console is enabled. The variable "i" is index of an array. Therefore
"has_preferred" is set only when preferred_console is >= 0. But then
it was already true because of the above code:

The nand_scan_ident() iterates over maxchips, and calls nand_reset()
for each. This driver currently passes the maximum number of banks
(=chip selects) supported by the controller as maxchips. So, maxchips
is typically 4 or 8. Usually, less number of NAND chips are connected
to the controller.
This patch series intends to solve various problems.
[1] The driver just retrieves the OOB area as-is
whereas the controller uses syndrome page layout.

Recent versions of this IP support automatic erased page detection.
If an erased page is detected on reads, the controller does not set
INTR__ECC_UNCOR_ERR, but INTR__ERASED_PAGE.
The detection of erased pages is based on the number of zeros in a
page; if the number of zeros is less than the value

This is from drm driver calling in idr_replace() w/ a negative id.
Probably a silly bug in error handling path?
Thanks.

HW bug description: in case of HW thread context switch
the dpc configuration of the exiting thread is dragged
one cycle into the next thread.
In order to avoid the consequences of this bug, the DPC register
is set to an initial value, and not changed afterwards.

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 reasons are:
1) speeding up boot time, becomes critical for many CPUs machine,

2) shorten kernel log at boot time, again easy to scan for large

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()
and once local_irq_enable() called can hit another one before we
managed to restore last one and pop so

Registers used by compare exchange instructions.
GPA1 is used for compare value, and EFLAGS got bit reflects
atomic operation response.
EFLAGS is zeroed for each new user task so it won't get its
parent value.

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.

1) I added "Handle memory error as an exception" patch from previous set
It now turn do_memory_error() into weak sybol.
It is then overriden by NPS400 platform, to simply call die().
2) This set is now based on arc-next branch

On ARC700, user mode memory error is treated as L2 interrupt, but NPS
hardware treats it as Machine Check exception.
Address this by defining an NPS specific bus error handler.

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.
