Initializing clk to NULL as a reset/error condition does not
help as NULL is not an invalid condition w.r.t clk. Remove this
initialization altogether as there is no state retention.

Add a driver for the hardware watchdogs in NVIDIA Tegra SoCs (Tegra30 and
later). This driver will configure one watchdog timer that will reset the
system in the case of a watchdog timeout.
This driver binds to the nvidia,tegra30-timer device node and gets its
register base from there.

It is advisable to disable the NMI before registering the IRQ handler as
registering the IRQ handler unmasks the IRQ on the GIC, so if U-Boot has
left the NMI enabled and the NMI pin is active we will immediately get
an interrupt before any driver has claimed the downstream interrupt of
the NMI.

The original MIPS hibernate code flushes cache and TLB entries in
swsusp_arch_resume(). But they are removed in Commit 44eeab67416711
(MIPS: Hibernation: Remove SMP TLB and cacheflushing code.). A cross-
CPU flush is surely unnecessary because all but the local CPU have
already been disabled. But a local flush (at least the TLB flush) is
needed. When we do hibernation on Loongson-3 with an E1000E NIC, it is
very easy to produce a kernel panic (kernel page fault, or unaligned
access). The root cause is E1000E driver use vzalloc_node() to allocate
pages, the stale TLB entries of the booting kernel will be misused by
the resumed target kernel.

The UART register names are identical to the ones in uapi/linux/serial_reg.h,
which causes build failures in various drivers when they indirectly pull in
the au1000.h header, for example via gpio.h:
In file included from arch/mips/include/asm/mach-au1x00/gpio.h:13:0,
from arch/mips/include/asm/gpio.h:4,
from include/linux/gpio.h:48,
from include/linux/ssb/ssb.h:9,
from drivers/ssb/driver_mipscore.c:11:
arch/mips/include/asm/mach-au1x00/au1000.h:1171:0: note: this is the location of the previous definition
#define UART_LSR 0x1C /* Line Status Register */
Get rid of the altogether, nothing in the core Alchemy code depends
on them any more.

because it can be a variable name like in linux/pm_domain.h [1]. So,

Daniel Borkmann says:
====================
BPF updates
We sat down and have heavily reworked the whole previous patchset
from v10 [1] to address all comments/concerns. This patchset therefore
*replaces* the internal BPF interpreter with the new layout as
discussed in [1], and migrates some exotic callers to properly use the
BPF API for a transparent upgrade. All other callers that already use
the BPF API in a way it should be used, need no further changes to run
the new internals. We also removed the sysctl knob entirely, and do not
expose any structure to userland, so that implementation details only
reside in kernel space. Since we are replacing the interpreter we had
to migrate seccomp in one patch along with the interpreter to not break
anything. When attaching a new filter, the flow can be described as
following: i) test if jit compiler is enabled and can compile the user
BPF, ii) if so, then go for it, iii) if not, then transparently migrate
the filter into the new representation, and run it in the interpreter.
Also, we have scratched the jit flag from the len attribute and made it
as initial patch in this series as Pablo has suggested in the last
feedback, thanks. For details, please refer to the patches themselves.
We did extensive testing of BPF and seccomp on the new interpreter
itself and also on the user ABIs and could not find any issues; new
performance numbers as posted in patch 8 are also still the same.
Please find more details in the patches themselves.
For all the previous history from v1 to v10, see [1]. We have decided
to drop the v11 as we have pedantically reworked the set, but of course,
included all previous feedback.
v3 -> v4:
- Applied feedback from Dave regarding swap insns
- Rebased on net-next
v2 -> v3:
- Rebased to latest net-next (i.e. w/ rxhash->hash rename)
- Fixed patch 8/9 commit message/doc as suggested by Dave
- Rest is unchanged
v1 -> v2:
- Rebased to latest net-next
- Added static to ptp_filter as suggested by Dave
- Fixed a typo in patch 8's commit message
- Rest unchanged
Thanks !
