b50776ae01 locking/atomics: Don't assume that scripts are executable
patch(1) doesn't set the x bit on files.  So if someone downloads and
applies patch-4.21.xz, their kernel won't build.  Fix that by executing
/bin/sh.

c53051128b sc16is7xx: put err_spi and err_i2c into correct #ifdef
err_spi is only called within SERIAL_SC16IS7XX_SPI
while err_i2c is called inside SERIAL_SC16IS7XX_I2C.
So we need to put err_spi and err_i2c into each #ifdef
accordingly.

This change fixes ("sc16is7xx: move label 'err_spi'
to correct section").

cef62a615d Merge tag 'misc-habanalabs-next-2019-04-19' of git://people.freedesktop.org/~gabbayo/linux into char-misc-next
Oded writes:

This tag contains many changes for kernel 5.2.

The major changes are:
- Add a new IOCTL for debug, profiling and trace operations on the device.
  This will allow the user to perform profiling and debugging of the
  deep learning topologies that are executing on the ASIC.

- Add a shadow table for the ASIC's MMU page tables to avoid doing page
  table walks on the device's DRAM during map/unmap operations.

- re-factor of ASIC-dependent code to be common code for all ASICs

In addition, there are many small fixes and changes. The notable ones are:
- Allow accessing the DRAM using virtual address through the debugFS
  interface. Until now, only physical addresses were valid, but that is
  useless for debugging when working with MMU.

- Allow the user to modify the TPC clock relaxation value to better
  control TPC power consumption during topology execution.

- Allow the user to inquire about the device's status
  (operational/Malfunction/in-reset) in the INFO IOCTL.

- Improvements to the device's removal function, to prevent crash in case
  of force removal by the OS.

- Prevent PTE read/write during hard-reset. This will improve stability of
  the device during hard-reset.

ff8acf9290 arm64: futex: Restore oldval initialization to work around buggy compilers
Commit 045afc2412 ("arm64: futex: Fix FUTEX_WAKE_OP atomic ops with
non-zero result value") removed oldval's zero initialization in
arch_futex_atomic_op_inuser because it is not necessary. Unfortunately,
Android's arm64 GCC 4.9.4 [1] does not agree:

../kernel/futex.c: In function 'do_futex':
../kernel/futex.c:1658:17: warning: 'oldval' may be used uninitialized
in this function [-Wmaybe-uninitialized]
   return oldval == cmparg;
                 ^
In file included from ../kernel/futex.c:73:0:
../arch/arm64/include/asm/futex.h:53:6: note: 'oldval' was declared here
  int oldval, ret, tmp;
      ^

GCC fails to follow that when ret is non-zero, futex_atomic_op_inuser
returns right away, avoiding the uninitialized use that it claims.
Restoring the zero initialization works around this issue.

738a7832d2 signal: use fdget() since we don't allow O_PATH
As stated in the original commit for pidfd_send_signal() we don't allow
to signal processes through O_PATH file descriptors since it is
semantically equivalent to a write on the pidfd.

We already correctly error out right now and return EBADF if an O_PATH
fd is passed.  This is because we use file->f_op to detect whether a
pidfd is passed and O_PATH fds have their file->f_op set to empty_fops
in do_dentry_open() and thus fail the test.

Thus, there is no regression.  It's just semantically correct to use
fdget() and return an error right from there instead of taking a
reference and returning an error later.

3f2552f7e9 timers/sched_clock: Prevent generic sched_clock wrap caused by tick_freeze()
tick_freeze() introduced by suspend-to-idle in commit 124cf9117c ("PM /
sleep: Make it possible to quiesce timers during suspend-to-idle") uses
timekeeping_suspend() instead of syscore_suspend() during
suspend-to-idle. As a consequence generic sched_clock will keep going
because sched_clock_suspend() and sched_clock_resume() are not invoked
during suspend-to-idle which can result in a generic sched_clock wrap.

On a ARM system with suspend-to-idle enabled, sched_clock is registered
as "56 bits at 13MHz, resolution 76ns, wraps every 4398046511101ns", which
means the real wrapping duration is 8796093022202ns.

[  134.551779] suspend-to-idle suspend (timekeeping_suspend())
[ 1204.912239] suspend-to-idle resume (timekeeping_resume())
......
[ 1206.912239] suspend-to-idle suspend (timekeeping_suspend())
[ 5880.502807] suspend-to-idle resume (timekeeping_resume())
......
[ 6000.403724] suspend-to-idle suspend (timekeeping_suspend())
[ 8035.753167] suspend-to-idle resume  (timekeeping_resume())
......
[ 8795.786684] (2)[321:charger_thread]......
[ 8795.788387] (2)[321:charger_thread]......
[    0.057226] (0)[0:swapper/0]......
[    0.061447] (2)[0:swapper/2]......

sched_clock was not stopped during suspend-to-idle, and sched_clock_poll
hrtimer was not expired because timekeeping_suspend() was invoked during
suspend-to-idle. It makes sched_clock wrap at kernel time 8796s.

To prevent this, invoke sched_clock_suspend() and sched_clock_resume() in
tick_freeze() together with timekeeping_suspend() and timekeeping_resume().

3fe3331bb2 perf/x86/amd: Add event map for AMD Family 17h
Family 17h differs from prior families by:

 - Does not support an L2 cache miss event
 - It has re-enumerated PMC counters for:
   - L2 cache references
   - front & back end stalled cycles

So we add a new amd_f17h_perfmon_event_map[] so that the generic
perf event names will resolve to the correct h/w events on
family 17h and above processors.

Reference sections 2.1.13.3.3 (stalls) and 2.1.13.3.6 (L2):

ec3937107a x86/mm/KASLR: Fix the size of the direct mapping section
kernel_randomize_memory() uses __PHYSICAL_MASK_SHIFT to calculate
the maximum amount of system RAM supported. The size of the direct
mapping section is obtained from the smaller one of the below two
values:

  (actual system RAM size + padding size) vs (max system RAM size supported)

This calculation is wrong since commit

  b83ce5ee91 ("x86/mm/64: Make __PHYSICAL_MASK_SHIFT always 52").

In it, __PHYSICAL_MASK_SHIFT was changed to be 52, regardless of whether
the kernel is using 4-level or 5-level page tables. Thus, it will always
use 4 PB as the maximum amount of system RAM, even in 4-level paging
mode where it should actually be 64 TB.

Thus, the size of the direct mapping section will always
be the sum of the actual system RAM size plus the padding size.

Even when the amount of system RAM is 64 TB, the following layout will
still be used. Obviously KALSR will be weakened significantly.

   |____|_______actual RAM_______|_padding_|______the rest_______|
   0            64TB                                            ~120TB

Instead, it should be like this:

   |____|_______actual RAM_______|_________the rest______________|
   0            64TB                                            ~120TB

The size of padding region is controlled by
CONFIG_RANDOMIZE_MEMORY_PHYSICAL_PADDING, which is 10 TB by default.

The above issue only exists when
CONFIG_RANDOMIZE_MEMORY_PHYSICAL_PADDING is set to a non-zero value,
which is the case when CONFIG_MEMORY_HOTPLUG is enabled. Otherwise,
using __PHYSICAL_MASK_SHIFT doesn't affect KASLR.

Fix it by replacing __PHYSICAL_MASK_SHIFT with MAX_PHYSMEM_BITS.

a7b1a4839f SUNRPC: Ignore queue transmission errors on successful transmission
If a request transmission fails due to write space or slot unavailability
errors, but the queued task then gets transmitted before it has time to
process the error in call_transmit_status() or call_bc_transmit_status(),
we need to suppress the transmission error code to prevent it from leaking
out of the RPC layer.

74f464e970 io_uring: fix CQ overflow condition
This is a leftover from when the rings initially were not free flowing,
and hence a test for tail + 1 == head would indicate full. Since we now
let them wrap instead of mask them with the size, we need to check if
they drift more than the ring size from each other.

This fixes a case where we'd overwrite CQ ring entries, if the user
failed to reap completions. Both cases would ultimately result in lost
completions as the application violated the depth it asked for. The only
difference is that before this fix we'd return invalid entries for the
overflowed completions, instead of properly flagging it in the
cq_ring->overflow variable.

Recent changes to support PERF_RECORD_KSYMBOL and PERF_RECORD_BPF_EVENT
broke --kallsyms option. This is because it broke test __map__is_kmodule.

This patch fixes this by adding check for bpf program, so that these maps

b2ecf00631 vt: fix cursor when clearing the screen
The patch a6dbe44275 ("vt: perform safe console erase in the right
order") introduced a bug. The conditional do_update_region() was
replaced by a call to update_region() that does contain the conditional
already, but with unwanted extra side effects such as restoring the cursor
drawing.

In order to reproduce the bug:
- use framebuffer console with the AMDGPU driver
- type "links" to start the console www browser
- press 'q' and space to exit links

Now the cursor will be permanently visible in the center of the
screen. It will stay there until something overwrites it.

The bug goes away if we change update_region() back to the conditional
do_update_region().

af4b54a2e5 staging: comedi: ni_usb6501: Fix possible double-free of ->usb_rx_buf
`ni6501_alloc_usb_buffers()` is called from `ni6501_auto_attach()` to
allocate RX and TX buffers for USB transfers.  It allocates
`devpriv->usb_rx_buf` followed by `devpriv->usb_tx_buf`.  If the
allocation of `devpriv->usb_tx_buf` fails, it frees
`devpriv->usb_rx_buf`, leaving the pointer set dangling, and returns an
error.  Later, `ni6501_detach()` will be called from the core comedi
module code to clean up.  `ni6501_detach()` also frees both
`devpriv->usb_rx_buf` and `devpriv->usb_tx_buf`, but
`devpriv->usb_rx_buf` may have already beed freed, leading to a
double-free error.  Fix it bu removing the call to
`kfree(devpriv->usb_rx_buf)` from `ni6501_alloc_usb_buffers()`, relying
on `ni6501_detach()` to free the memory.

660cf4ce9d staging: comedi: ni_usb6501: Fix use of uninitialized mutex
If `ni6501_auto_attach()` returns an error, the core comedi module code
will call `ni6501_detach()` to clean up.  If `ni6501_auto_attach()`
successfully allocated the comedi device private data, `ni6501_detach()`
assumes that a `struct mutex mut` contained in the private data has been
initialized and uses it.  Unfortunately, there are a couple of places
where `ni6501_auto_attach()` can return an error after allocating the
device private data but before initializing the mutex, so this
assumption is invalid.  Fix it by initializing the mutex just after
allocating the private data in `ni6501_auto_attach()` before any other
errors can be retturned.  Also move the call to `usb_set_intfdata()`
just to keep the code a bit neater (either position for the call is
fine).

I believe this was the cause of the following syzbot crash report

50ce163a72 tcp: tcp_grow_window() needs to respect tcp_space()
For some reason, tcp_grow_window() correctly tests if enough room
is present before attempting to increase tp->rcv_ssthresh,
but does not prevent it to grow past tcp_space()

This is causing hard to debug issues, like failing
the (__tcp_select_window(sk) >= tp->rcv_wnd) test
in __tcp_ack_snd_check(), causing ACK delays and possibly
slow flows.

Depending on tcp_rmem[2], MTU, skb->len/skb->truesize ratio,
we can see the problem happening on "netperf -t TCP_RR -- -r 2000,2000"
after about 60 round trips, when the active side no longer sends
immediate acks.

f7a937801b tipc: fix link established but not in session
According to the link FSM, when a link endpoint got RESET_MSG (- a
traditional one without the stopping bit) from its peer, it moves to
PEER_RESET state and raises a LINK_DOWN event which then resets the
link itself. Its state will become ESTABLISHING after the reset event
and the link will be re-established soon after this endpoint starts to
send ACTIVATE_MSG to the peer.

There is no problem with this mechanism, however the link resetting has
cleared the link 'in_session' flag (along with the other important link
data such as: the link 'mtu') that was correctly set up at the 1st step
(i.e. when this endpoint received the peer RESET_MSG). As a result, the
link will become ESTABLISHED, but the 'in_session' flag is not set, and
all STATE_MSG from its peer will be dropped at the link_validate_msg().
It means the link not synced and will sooner or later face a failure.

Since the link reset action is obviously needed for a new link session
(this is also true in the other situations), the problem here is that
the link is re-established a bit too early when the link endpoints are
not really in-sync yet. The commit forces a resync as already done in
the previous commit 91986ee166 ("tipc: fix link session and
re-establish issues") by simply varying the link 'peer_session' value
at the link_reset().

3b2e2904de net: bridge: fix per-port af_packet sockets
When the commit below was introduced it changed two visible things:
 - the skb was no longer passed through the protocol handlers with the
   original device
 - the skb was passed up the stack with skb->dev = bridge

The first change broke af_packet sockets on bridge ports. For example we
use them for hostapd which listens for ETH_P_PAE packets on the ports.
We discussed two possible fixes:
 - create a clone and pass it through NF_HOOK(), act on the original skb
   based on the result
 - somehow signal to the caller from the okfn() that it was called,
   meaning the skb is ok to be passed, which this patch is trying to
   implement via returning 1 from the bridge link-local okfn()

Note that we rely on the fact that NF_QUEUE/STOLEN would return 0 and
drop/error would return < 0 thus the okfn() is called only when the
return was 1, so we signal to the caller that it was called by preserving
the return value from nf_hook().

a885bcfd15 ipmi: ipmi_si_hardcode.c: init si_type array to fix a crash
The intended behavior of function ipmi_hardcode_init_one() is to default
to kcs interface when no type argument is presented when initializing
ipmi with hard coded addresses.

However, the array of char pointers allocated on the stack by function
ipmi_hardcode_init() was not inited to zeroes, so it contained stack
debris.

Consequently, passing the cruft stored in this array to function
ipmi_hardcode_init_one() caused a crash when it was unable to detect
that the char * being passed was nonsense and tried to access the
address specified by the bogus pointer.

The fix is simply to initialize the si_type array to zeroes, so if
there were no type argument given to at the command line, function
ipmi_hardcode_init_one() could properly default to the kcs interface.

   - The addition of a 32-bit defconfig, to emphasize testing the 32-bit
     port.

   - A device tree bindings patch, which is pre-work for some patches
     that target 5.2.

   - A fix to support booting on systems with more physical memory than
     the maximum supported by the kernel"
