530e9b76ae cpu/hotplug: Remove obsolete cpu hotplug register/unregister functions
hotcpu_notifier(), cpu_notifier(), __hotcpu_notifier(), __cpu_notifier(),
register_hotcpu_notifier(), register_cpu_notifier(),
__register_hotcpu_notifier(), __register_cpu_notifier(),
unregister_hotcpu_notifier(), unregister_cpu_notifier(),
__unregister_hotcpu_notifier(), __unregister_cpu_notifier()

are unused now. Remove them and all related code.

Remove also the now pointless cpu notifier error injection mechanism. The
states can be executed step by step and error rollback is the same as cpu
down, so any state transition can be tested w/o requiring the notifier
error injection.

Some CPU hotplug states are kept as they are (ab)used for hotplug state
tracking.

e210faa235 scsi/bnx2i: Convert to hotplug state machine
Install the callbacks via the state machine. No functional change.

This is the minimal fixup so we can remove the hotplug notifier mess
completely.

The real rework of this driver to use work queues is still stuck in
review/testing on the SCSI mailing list.

eb254f323b Merge branch 'x86-cache-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cache allocation interface from Thomas Gleixner:
 "This provides support for Intel's Cache Allocation Technology, a cache
  partitioning mechanism.

  The interface is odd, but the hardware interface of that CAT stuff is
  odd as well.

  We tried hard to come up with an abstraction, but that only allows
  rather simple partitioning, but no way of sharing and dealing with the
  per package nature of this mechanism.

  In the end we decided to expose the allocation bitmaps directly so all
  combinations of the hardware can be utilized.

  There are two ways of associating a cache partition:

   - Task

     A task can be added to a resource group. It uses the cache
     partition associated to the group.

   - CPU

     All tasks which are not member of a resource group use the group to
     which the CPU they are running on is associated with.

     That allows for simple CPU based partitioning schemes.

  The main expected user sare:

   - Virtualization so a VM can only trash only the associated part of
     the cash w/o disturbing others

   - Real-Time systems to seperate RT and general workloads.

   - Latency sensitive enterprise workloads

   - In theory this also can be used to protect against cache side
     channel attacks"

[ Intel RDT is "Resource Director Technology". The interface really is
  rather odd and very specific, which delayed this pull request while I
  was thinking about it. The pull request itself came in early during
  the merge window, I just delayed it until things had calmed down and I
  had more time.

  But people tell me they'll use this, and the good news is that it is
  _so_ specific that it's rather independent of anything else, and no
  user is going to depend on the interface since it's pretty rare. So if
  push comes to shove, we can just remove the interface and nothing will
  break ]

1b011e2f13 ratelimit: fix WARN_ON_RATELIMIT return value
The macro is to be used similarly as WARN_ON as:

  if (WARN_ON_RATELIMIT(condition, state))
	do_something();

One would expect only 'condition' to affect the 'if', but
WARN_ON_RATELIMIT does internally only:

  WARN_ON((condition) && __ratelimit(state))

So the 'if' is affected by the ratelimiting state too.  Fix this by
returning 'condition' in any case.

Note that nobody uses WARN_ON_RATELIMIT yet, so there is nothing to
worry about.  But I was about to use it and was a bit surprised.

7b8589cc29 ima: on soft reboot, save the measurement list
The TPM PCRs are only reset on a hard reboot.  In order to validate a
TPM's quote after a soft reboot (eg.  kexec -e), the IMA measurement
list of the running kernel must be saved and restored on boot.

This patch uses the kexec buffer passing mechanism to pass the
serialized IMA binary_runtime_measurements to the next kernel.

5ccb071e97 bpf: fix overflow in prog accounting
Commit aaac3ba95e ("bpf: charge user for creation of BPF maps and
programs") made a wrong assumption of charging against prog->pages.
Unlike map->pages, prog->pages are still subject to change when we
need to expand the program through bpf_prog_realloc().

This can for example happen during verification stage when we need to
expand and rewrite parts of the program. Should the required space
cross a page boundary, then prog->pages is not the same anymore as
its original value that we used to bpf_prog_charge_memlock() on. Thus,
we'll hit a wrap-around during bpf_prog_uncharge_memlock() when prog
is freed eventually. I noticed this that despite having unlimited
memlock, programs suddenly refused to load with EPERM error due to
insufficient memlock.

There are two ways to fix this issue. One would be to add a cached
variable to struct bpf_prog that takes a snapshot of prog->pages at the
time of charging. The other approach is to also account for resizes. I
chose to go with the latter for a couple of reasons: i) We want accounting
rather to be more accurate instead of further fooling limits, ii) adding
yet another page counter on struct bpf_prog would also be a waste just
for this purpose. We also do want to charge as early as possible to
avoid going into the verifier just to find out later on that we crossed
limits. The only place that needs to be fixed is bpf_prog_realloc(),
since only here we expand the program, so we try to account for the
needed delta and should we fail, call-sites check for outcome anyway.
On cBPF to eBPF migrations, we don't grab a reference to the user as
they are charged differently. With that in place, my test case worked
fine.

aafe6ae9ce bpf: dynamically allocate digest scratch buffer
Geert rightfully complained that 7bd509e311 ("bpf: add prog_digest
and expose it via fdinfo/netlink") added a too large allocation of
variable 'raw' from bss section, and should instead be done dynamically:

  # ./scripts/bloat-o-meter kernel/bpf/core.o.1 kernel/bpf/core.o.2
  add/remove: 3/0 grow/shrink: 0/0 up/down: 33291/0 (33291)
  function                                     old     new   delta
  raw                                            -   32832  +32832
  [...]

Since this is only relevant during program creation path, which can be
considered slow-path anyway, lets allocate that dynamically and be not
implicitly dependent on verifier mutex. Move bpf_prog_calc_digest() at
the beginning of replace_map_fd_with_map_ptr() and also error handling
stays straight forward.

cb02de96ec x86/mpx: Move bd_addr to mm_context_t
Currently bd_addr lives in mm_struct, which is otherwise architecture
independent. Architecture-specific data is supposed to live within
mm_context_t (itself contained in mm_struct).

Other x86-specific context like the pkey accounting data lives in
mm_context_t, and there's no readon the MPX data can't also live there.
So as to keep the arch-specific data togather, and to set a good example
for others, this patch moves bd_addr into x86's mm_context_t.

59331c215d A varied set of changes:
- a large rework of cephx auth code to cope with CONFIG_VMAP_STACK
   (myself).  Also fixed a deadlock caused by a bogus allocation on the
   writeback path and authorize reply verification.
 
 - a fix for long stalls during fsync (Jeff Layton).  The client now
   has a way to force the MDS log flush, leading to ~100x speedups in
   some synthetic tests.
 
 - a new [no]require_active_mds mount option (Zheng Yan).  On mount, we
   will now check whether any of the MDSes are available and bail rather
   than block if none are.  This check can be avoided by specifying the
   "no" option.
 
 - a couple of MDS cap handling fixes and a few assorted patches

Highlights include:
 
  - Support for the kexec_file_load() syscall, which is a prereq for secure and
    trusted boot.
 
  - Prevent kernel execution of userspace on P9 Radix (similar to SMEP/PXN).
 
  - Sort the exception tables at build time, to save time at boot, and store
    them as relative offsets to save space in the kernel image & memory.
 
  - Allow building the kernel with thin archives, which should allow us to build
    an allyesconfig once some other fixes land.
 
  - Build fixes to allow us to correctly rebuild when changing the kernel endian
    from big to little or vice versa.
 
  - Plumbing so that we can avoid doing a full mm TLB flush on P9 Radix.
 
  - Initial stack protector support (-fstack-protector).
 
  - Support for dumping the radix (aka. Linux) and hash page tables via debugfs.
 
  - Fix an oops in cxl coredump generation when cxl_get_fd() is used.
 
  - Freescale updates from Scott: "Highlights include 8xx hugepage support,
    qbman fixes/cleanup, device tree updates, and some misc cleanup."
 
  - Many and varied fixes and minor enhancements as always.

57ca04ab44 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull m ore s390 updates from Martin Schwidefsky:
 "Over 95% of the changes in this pull request are related to the zcrypt
  driver. There are five improvements for zcrypt: the ID for the CEX6
  cards is added, workload balancing and multi-domain support are
  introduced, the debug logs are overhauled and a set of tracepoints is
  added.

  Then there are several patches in regard to inline assemblies. One
  compile fix and several missing memory clobbers. As far as we can tell
  the omitted memory clobbers have not caused any breakage.

  A small change to the PCI arch code, the machine can tells us how big
  the function measurement blocks are. The PCI function measurement will
  be disabled for a device if the queried length is larger than the
  allocated size for these blocks.

  And two more patches to correct five printk messages.

  That is it for s390 in regard to the 4.10 merge window. Happy holidays"

ed3c5a0be3 virtio, vhost: new device, fixes, speedups
This includes the new virtio crypto device, and fixes all over the
 place.  In particular enabling endian-ness checks for sparse builds
 found some bugs which this fixes.  And it appears that everyone is in
 agreement that disabling endian-ness sparse checks shouldn't be
 necessary any longer.
 
 So this enables them for everyone, and drops __CHECK_ENDIAN__
 and __bitwise__ APIs.
 
 IRQ handling in virtio has been refactored somewhat, the
 larger switch to IRQ_SHARED will have to wait as
 it proved too aggressive.

Clients can set the umask attribute when creating files to cause the
server to apply it always except when inheriting permissions from the
parent directory.  That way, the new files will end up with the same
permissions as files created locally.

991688bfc6 ARM: SoC driver updates for v4.10
Driver updates for ARM SoCs, including a couple of newly added drivers:
 
 - A new driver for the power management controller on TI Keystone
 - Support for the prerelease "SCPI" firmware protocol that ended up
   being shipped by Amlogic in their GXBB SoC.
 - A soc_device can now be matched using a glob from inside the
   kernel, when another driver wants to know the specific chip
   it is running on and cannot find out from DT, firmware or hardware.
 - Renesas SoCs now support identification through the soc_device
   interface, both in user space and kernel.
 - Renesas r8a7743 and r8a7745 gain support for their system controller
 - A new checking module for the ARM "PSCI" (not to be confused
   with "SCPI" mentioned above) firmware interface.
 - A new driver for the Tegra GMI memory interface
 - Support for the Tegra firmware interfaces with their
   power management controllers
 
 As usual, the updates for the reset controller framework are merged
 here, as they tend to touch multiple SoCs as well, including a new
 driver for the Oxford (now Broadcom) OX820 chip and the Tegra
 bpmp interface.
 
 The existing drivers for Atmel, Qualcomm, NVIDIA, TI Davinci, and
 Rockchips SoCs see some further updates.
 
 Conflicts:
 - ARCH_RENESAS now selects SOC_BUS, but no longer needs GPIOLIB
 - drivers/soc/renesas/Makefile: multiple files got added, keep
   all in logical sorting
