commit 9c4bf5e0db164f330a2d3e128e9832661f69f0e9 upstream.
The function_graph_enter() function does the work of calling the function
graph hook function and the management of the shadow stack, simplifying the
work done in the architecture dependent prepare_ftrace_return().Have sparc use the new code, and remove the shadow stack management as well as
having to set up the trace structure.This is needed to prepare for a fix of a design bug on how the curr_ret_stack
is used.Cc: "David S. Miller"

[ Upstream commit 5b4fc3882a649c9411dd0dcad2ddb78e911d340e ]
Right now if we get a corrupted user stack frame we do a
do_exit(SIGILL) which is not helpful.If under a debugger, this behavior causes the inferior process to
exit. So the register and other state cannot be examined at the time
of the event.Instead, conditionally log a rate limited kernel log message and then
force a SIGSEGV.With bits and ideas borrowed (as usual) from powerpc.

If we did some signal processing, we have to reload the pt_regs
tstate register because it's value may have changed.In doing so we also have to extract the %pil value contained in there
anre load that into %l4.This value is at bit 20 and thus needs to be shifted down before we
later write it into the %pil register.Most of the time this is harmless as we are returning to userspace
and the %pil is zero for that case.Signed-off-by: David S. Miller

Like x86 and arm, call perf_sample_event_took() in perf event
NMI interrupt handler.Signed-off-by: David S. Miller
-
It is important to clear the hw->state value for non-stopped events
when they are added into the PMU. Otherwise when the event is
scheduled out, we won't read the counter because HES_UPTODATE is still
set. This breaks 'perf stat' and similar use cases, causing all the
events to show zero.This worked for multi-pcr because we make explicit sparc_pmu_start()
calls in calculate_multiple_pcrs(). calculate_single_pcr() doesn't do
this because the idea there is to accumulate all of the counter
settings into the single pcr value. So we have to add explicit
hw->state handling there.Like x86, we use the PERF_HES_ARCH bit to track truly stopped events
so that we don't accidently start them on a reload.Related to all of this, sparc_pmu_start() is missing a userpage update
so add it.Signed-off-by: David S. Miller

Holding uts_sem as a writer while accessing userspace memory allows a
namespace admin to stall all processes that attempt to take uts_sem.
Instead, move data through stack buffers and don't access userspace memory
while uts_sem is held.Cc: stable@vger.kernel.org

The BTF conflicts were simple overlapping changes.
The virtio_net conflict was an overlap of a fix of statistics counter,
happening alongisde a move over to a bonafide statistics structure
rather than counting value on the stack.Signed-off-by: David S. Miller

Almost all architectures include it. Add a ARCH_NO_PREEMPT symbol to
disable preempt support for alpha, hexagon, non-coldfire m68k and
user mode Linux.Signed-off-by: Christoph Hellwig

Move the source of lib/Kconfig.debug and arch/$(ARCH)/Kconfig.debug to
the top-level Kconfig. For two architectures that means moving their
arch-specific symbols in that menu into a new arch Kconfig.debug file,
and for a few more creating a dummy file so that we can include it
unconditionally.Also move the actual 'Kernel hacking' menu to lib/Kconfig.debug, where
it belongs.Signed-off-by: Christoph Hellwig

Instead of duplicating the source statements in every architecture just
do it once in the toplevel Kconfig file.Note that with this the inclusion of arch/$(SRCARCH/Kconfig moves out of
the top-level Kconfig into arch/Kconfig so that don't violate ordering
constraits while keeping a sensible menu structure.Signed-off-by: Christoph Hellwig

Some drivers need these for compile-testing. On most architectures
they come from asm-generic/io.h, but not on sparc64, which has its
own definitions.Since we already have ioread*_rep()/iowrite*_rep() that have the
same behavior on sparc64 (i.e. all PCI I/O space is memory mapped),
we can rename the existing helpers and add macros to define them
to the same implementation.Signed-off-by: Arnd Bergmann
