commit cb42c9a3ebbbb23448c3f9a25417fae6309b1a92

sched/core: Add debugging code to catch missing update_rq_clock() calls
There's no diagnostic checks for figuring out when we've accidentally
missed update_rq_clock() calls. Let's add some by piggybacking on the
rq_*pin_lock() wrappers.
The idea behind the diagnostic checks is that upon pining rq lock the
rq clock should be updated, via update_rq_clock(), before anybody
reads the clock with rq_clock() or rq_clock_task().
The exception to this rule is when updates have explicitly been
disabled with the rq_clock_skip_update() optimisation.
There are some functions that only unpin the rq lock in order to grab
some other lock and avoid deadlock. In that case we don't need to
update the clock again and the previous diagnostic state can be
carried over in rq_repin_lock() by saving the state in the rq_flags
context.
Since this patch adds a new clock update flag and some already exist
in rq::clock_skip_update, that field has now been renamed. An attempt
has been made to keep the flag manipulation code small and fast since
it's used in the heart of the __schedule() fast path.
For the !CONFIG_SCHED_DEBUG case the only object code change (other
than addresses) is the following change to reset RQCF_ACT_SKIP inside
of __schedule(),
- c7 83 38 09 00 00 00 movl $0x0,0x938(%rbx)
- 00 00 00

[x86] a75a3f6fc9 Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b
by Fengguang Wu
Greetings,
FYI here is an old bug, however is still active in mainline kernel.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
commit a75a3f6fc92888e4119744d8594ffdf748c3d444

Merge branch 'x86-asm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 asm changes from Ingo Molnar:
"The main change in this cycle is another step in the big x86 system
call interface rework by Andy Lutomirski, which moves most of the low
level x86 entry code from assembly to C, for all syscall entries
except native 64-bit system calls:

arch/x86/entry/entry_64_compat.S | 547 ++++++++-----------------------
194 insertions(+), 535 deletions(-)
... our hope is that the final remaining step (converting native
64-bit system calls) will be less painful as all the previous steps,
given that most of the legacies and quirks are concentrated around
native 32-bit and compat environments"

[rhashtable] da20420f83: [ INFO: suspicious RCU usage. ]
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
git://internal_merge_and_test_tree devel-catchup-201702180234
commit da20420f83ea0fbcf3d03afda08d971ea1d8a356
Author: Herbert Xu <herbert(a)gondor.apana.org.au>
AuthorDate: Sat Feb 11 19:26:47 2017 +0800
Commit: David S. Miller <davem(a)davemloft.net>
CommitDate: Fri Feb 17 12:28:35 2017 -0500
rhashtable: Add nested tables
This patch adds code that handles GFP_ATOMIC kmalloc failure on
insertion. As we cannot use vmalloc, we solve it by making our
hash table nested. That is, we allocate single pages at each level
and reach our desired table size by nesting them.
When a nested table is created, only a single page is allocated
at the top-level. Lower levels are allocated on demand during
insertion. Therefore for each insertion to succeed, only two
(non-consecutive) pages are needed.
After a nested table is created, a rehash will be scheduled in
order to switch to a vmalloced table as soon as possible. Also,
the rehash code will never rehash into a nested table. If we
detect a nested table during a rehash, the rehash will be aborted
and a new rehash will be scheduled.

[genirq] f91f694540 BUG: unable to handle kernel NULL pointer dereference at 0000002c

genirq: Reenable shared irq debugging in request_*_irq()
Commit 6d83f94db95c ("genirq: Disable the SHIRQ_DEBUG call in
request_threaded_irq for now") disabled the SHIRQ_DEBUG facility for the
irq request side. Unfortunately the 'for now' part and the _FIXME add on to
the CONFIG_SHIRQ_DEBUG guard got forgotten.
It's unfortunately not possible to keep the original idea of just invoking
the newly installed handler due to the reasons described in the commit
which disabled it, but having this debug facility available makes a lot of
sense.
The only way to regain that testing is to invoke the real interrupt
handling mechanism, which will also invoke an already registered handler,
but that's not an issue because _all_ interrupt handlers need to be
prepared for handling spurious interrupts.

[USB] bea5b158ff WARNING: CPU: 0 PID: 1 at lib/list_debug.c:33 __list_add
by Fengguang Wu
Greetings,
FYI, this debug patch triggers bug in USB subsystem.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
commit bea5b158ff0da9c7246ff391f754f5f38e34577a
Author: Rob Herring <robh(a)kernel.org>

driver core: add test of driver remove calls during probe
In recent discussions on ksummit-discuss[1], it was suggested to do a
sequence of probe, remove, probe for testing driver remove paths. This
adds a kconfig option for said test.

x86/mm: Warn on W^X mappings
Warn on any residual W+X mappings after setting NX
if DEBUG_WX is enabled. Introduce a separate
X86_PTDUMP_CORE config that enables the code for
dumping the page tables without enabling the debugfs
interface, so that DEBUG_WX can be enabled without
exposing the debugfs interface. Switch EFI_PGT_DUMP
to using X86_PTDUMP_CORE so that it also does not require
enabling the debugfs interface.
On success it prints this to the kernel log:
x86/mm: Checked W+X mappings: passed, no W+X pages found.
On failure it prints a warning and a count of the failed pages:

[ Improved the Kconfig help text and made the new option default-y
if CONFIG_DEBUG_RODATA=y, because it already found buggy mappings,
so we really want people to have this on by default. ]

[genirq] f91f694540: BUG: unable to handle kernel NULL pointer dereference at 0000002c
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master
commit f91f694540f3f8ed25da57814fe0c673afd36e7e
Author: Thomas Gleixner <tglx(a)linutronix.de>
AuthorDate: Wed Feb 15 15:43:54 2017 +0100
Commit: Thomas Gleixner <tglx(a)linutronix.de>
CommitDate: Thu Feb 16 15:32:19 2017 +0100
genirq: Reenable shared irq debugging in request_*_irq()
Commit 6d83f94db95c ("genirq: Disable the SHIRQ_DEBUG call in
request_threaded_irq for now") disabled the SHIRQ_DEBUG facility for the
irq request side. Unfortunately the 'for now' part and the _FIXME add on to
the CONFIG_SHIRQ_DEBUG guard got forgotten.
It's unfortunately not possible to keep the original idea of just invoking
the newly installed handler due to the reasons described in the commit
which disabled it, but having this debug facility available makes a lot of
sense.
The only way to regain that testing is to invoke the real interrupt
handling mechanism, which will also invoke an already registered handler,
but that's not an issue because _all_ interrupt handlers need to be
prepared for handling spurious interrupts.

Convert rwsem to use waitlists
Saves one pointer, which shrinks struct inode by 16 bytes (as it contains
two rwsems), mm_struct by 8 bytes and the superblock by 8 bytes.

[driver core] bea5b158ff WARNING: CPU: 0 PID: 1 at drivers/ata/libata-core.c:6482 ata_port_detach
by Fengguang Wu
Hi Rob,
We see this WARNING in both mainline and linux-next kernels.
commit bea5b158ff0da9c7246ff391f754f5f38e34577a

driver core: add test of driver remove calls during probe
In recent discussions on ksummit-discuss[1], it was suggested to do a
sequence of probe, remove, probe for testing driver remove paths. This
adds a kconfig option for said test.
