Hi,
I was debugging a hang on a ppc64le kernel built with clang, and it
looks to be undefined behaviour with pointer wrapping in the llist code.
A test case is below. llist_for_each_entry() does container_of() on a
NULL pointer, which wraps our pointer negative, then adds the same
offset back in

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.
As I don't have the hardware, I'd be very pleased if
someone may test this patch.

Hello!
This series provides updates to SRCU:

tracking. Algorithm courtesy of Mathieu Desnoyers, implementation

2. Force full grace-period ordering in SRCU.
3. Add CBMC-based for
From: Lance Roy
SRCU uses two per-cpu counters: a nesting counter to count the number of
active critical sections, and a sequence counter to ensure that the nesting
counters don't change while they are being added together in
srcu_readers_active_idx_check().
This patch instead uses per-cpu lock
If a process invokes synchronize_srcu(), is delayed just the right amount
of time, and thus does not sleep when waiting for the grace period to
complete, there is no ordering between the end of the grace period and
the code following the synchronize_srcu(). Similarly, there can be a
lack of orderi
From: Lance Roy
This commit creates a formal/srcu-cbmc directory containing scripts that
pull SRCU in from the source code, filter it to remove things that CBMC
cannot handle, and run a series of verifications on it. This has a number
of shortcomings:
1. It does not yet hook into the upper
If a GUID Partition Table claims to have more than 2**25 entries, the
calculation of the partition table size in alloc_read_gpt_entries() will
overflow a 32-bit integer and not enough space will be allocated for the
table.
Nothing seems to get written out of bounds, but later efi_partition() will

This series removes some unused code and related comments,
addresses the warnings generated by 'make W=1' and 'make C=1'
and fixes a theoretical bug in the bus reset method in atari_scsi.
There's also a patch to add a missing error check during target

Avoid various warnings from "make C=1" by annotating a couple of
unlock-then-lock sequences, replacing a zero with NULL and
correcting some type casts.
Also avoid a warning from "make W=1" by adding braces.

Remove dead code inside #if 0 conditionals.
Remove the #ifdef __KERNEL__ test, since NCR5380.h has no definitions
that relate to userspace code.

The atari_scsi driver should not access Falcon DMA chip registers
unless it has acquired exclusive access to that chip. If the driver
doesn't have exclusive access then there's no need for a DMA reset
as there are no scsi commands in progress.

The DIFFERENTIAL and PARITY option macros are unused: no supported
hardware uses differential signalling and the core driver never
implemented parity checking. These options just waste space in the host
info string.
While we are here, fix a typo in the NCR5380_info() kernel-doc comment.
