In the existing dn_route.c code, dn_route_output_slow() takes
dst->__refcnt before calling dn_insert_route() while dn_route_input_slow()
does not take dst->__refcnt before calling dn_insert_route().
This makes the whole routing code very buggy.
In dn_dst_check_expire(), dnrt_free() is called when rt expires. This
makes the routes inserted by dn_route_output_slow() not able to be
freed as the refcnt is not released.
In dn_dst_gc(), dnrt_drop() is called to release rt which could
potentially cause the dst->__refcnt to be dropped to -1.
In dn_run_flush(), dst_free() is called to release all the dst. Again,
it makes the dst inserted by dn_route_output_slow() not able to be
released and also, it does not wait on the rcu and could potentially
cause crash in the path where other users still refer to this dst.
This patch makes sure both input and output path do not take
dst->__refcnt before calling dn_insert_route() and also makes sure
dnrt_free()/dst_free() is called when removing dst from the hash table.
The only difference between those 2 calls is that dnrt_free() waits on
the rcu while dst_free() does not.

The PC returned by dwfl_frame_pc() may map into a not-yet-reported
module. We have to report it before we continue unwinding. But when we
query for the isactivation flag in dwfl_frame_pc, libdw will actually do
one more unwinding step internally which can then break and lead to
missed frames or broken stacks.
With libunwind we get e.g.:

When a kthread calls call_usermodehelper() the steps are:

2. load_elf_binary()
3. populate current->thread.regs
While doing this, interrupts are not disabled. If there is a perf

but not yet reached to step 3) and if perf tries to read userspace
regs, kernel oops with following log:

On Power9, trying to use data breakpoints throws the splat shown
below. This is because the check for a data breakpoint in DSISR is in
do_hash_page(), which is not called when in Radix mode.

Move the check to handle_page_fault() so as to catch data breakpoints
in both Hash and Radix MMU modes.
We have to change the check in do_hash_page() against 0xa410 to use
0xa450, so as to include the value of (DSISR_DABRMATCH << 16).
There are two sites that call handle_page_fault() when in Radix, both
already pass DSISR in r4.

ftrace_caller() depends on a modified regs->nip to detect if a certain
function has been livepatched. However, with KPROBES_ON_FTRACE, it is
possible for regs->nip to have been modified by the kprobes pre_handler
(jprobes, for instance). In this case, we do not want to invoke the
livepatch_handler so as not to consume the livepatch stack.
To distinguish between the two (kprobes and livepatch), we check if
there is an active kprobe on the current function. If there is, then we
know for sure that it must have modified the NIP as we don't support
livepatching a kprobe'd function. In this case, we simply skip the
livepatch_handler and branch to the new NIP. Otherwise, the
livepatch_handler is invoked.

For DYNAMIC_FTRACE_WITH_REGS, we should be passing-in the original set
of registers in pt_regs, to capture the state _before_ ftrace_caller.
However, we are instead passing the stack pointer *after* allocating a
stack frame in ftrace_caller. Fix this by saving the proper value of r1
in pt_regs. Also, use SAVE_10GPRS() to simplify the code.

This fixes a crash when function_graph and jprobes are used together.
This is essentially commit 237d28db036e ("ftrace/jprobes/x86: Fix
conflict between jprobes and function graph tracing"), but for powerpc.
Jprobes breaks function_graph tracing since the jprobe hook needs to use
jprobe_return(), which never returns back to the hook, but instead to
the original jprobe'd function. The solution is to momentarily pause
function_graph tracing before invoking the jprobe hook and re-enable it
when returning back to the original jprobe'd function.

Instead of just the six patches to bnxt_re that I had anticipated,
there are another five IPoIB patches, two qedr patches, and a few
other miscellaneous patches.
The bnxt_re patches are more lines of diff than I like to submit this
late in the game. That's mostly because of the first two patches in
the series of six. I almost dropped them just because of the lines of
churn, but on a close review, a lot of the churn came from removing
duplicated code sections and consolidating them into callable
routines. I felt like this made the number of lines of change more
acceptable, and they address problems, so I left them. The remainder
of the patches are all small, well contained, and well understood.
These have passed 0day testing, but have not been submitted to
linux-next (but a local merge test with your current master was
without any conflicts).
Summary:
- A fix for fix eea40b8f624 ("infiniband: call ipv6 route lookup via
the stub interface")
- Six patches against bnxt_re...the first two are considerably larger
than I would like, but as they address real issues I went ahead and
submitted them (it also helped that a good deal of the churn was
removing code repeated in multiple places and consolidating it to
one common function)
- Two fixes against qedr that just came in
- One fix against rxe that took a few revisions to get right plus
time to get the proper reviews
- Five late breaking IPoIB fixes
- One late cxgb4 fix"

When trapped on WARN_ON(), report_bug() is expected to return
BUG_TRAP_TYPE_WARN so the caller will increment NIP by 4 and continue.
The __builtin_constant_p() path of the PPC's WARN_ON()
calls (indirectly) __WARN_FLAGS() which has BUGFLAG_WARNING set,
however the other branch does not which makes report_bug() report a
bug rather than a warning.
Fixes: f26dee15103f ("debug: Avoid setting BUGFLAG_WARNING twice")

POWER9 DD1 has an erratum where writing to the TBU40 register, which
is used to apply an offset to the timebase, can cause the timebase to
lose counts. This results in the timebase on some CPUs getting out of
sync with other CPUs, which then results in misbehaviour of the
timekeeping code.
To work around the problem, we make KVM ignore the timebase offset for
all guests on POWER9 DD1 machines. This means that live migration
cannot be supported on POWER9 DD1 machines.

Mellanox mlx5 fixes 2017-06-14
This series contains some fixes for the mlx5 core and netdev driver.
Please pull and let me know if there's any problem.
For -stable:
("net/mlx5: Wait for FW readiness before initializing command interface") kernels >= 4.4
("net/mlx5e: Fix timestamping capabilities reporting") kernels >= 4.5
("net/mlx5e: Avoid doing a cleanup call if the profile doesn't have it") kernels >= 4.9
("net/mlx5e: Fix min inline value for VF rep SQs") kernels >= 4.11
The "net/mlx5e: Fix min inline .." (a oneliner patch) doesn't cleanly apply
to 4.11, it hits a contextual conflict and can be easily resolved by:
+ mlx5_query_min_inline(mdev, &priv->params.tx_min_inline_mode);
to the end of mlx5e_build_rep_netdev_priv. Note the 2nd parameter of
mlx5_query_min_inline is slightly different from the original one.

At present, HV KVM on POWER8 and POWER9 machines loses any instruction
or data breakpoint set in the host whenever a guest is run.
Instruction breakpoints are currently only used by xmon, but ptrace
and the perf_event subsystem can set data breakpoints as well as xmon.
To fix this, we save the host values of the debug registers (CIABR,
DAWR and DAWRX) before entering the guest and restore them on exit.
To provide space to save them in the stack frame, we expand the stack
frame allocated by kvmppc_hv_entry() from 112 to 144 bytes.
