Mark flush request as IDLE in its .end_io(), aligning it with how normal
requests behave. The flush request stays in in-flight tags if we're not
using an IO scheduler, so we need to change its state into IDLE.
Otherwise, we will hang in blk_mq_tagset_wait_completed_request() during
error recovery because flush the request state is kept as COMPLETED.

Commit 39d114dd ("arm64: add KASAN support") added .weak directives to
arch/arm64/lib/mem*.S instead of changing the existing SYM_FUNC_START_PI
macros. This can lead to the assembly snippet `.weak memcpy ... .globl
memcpy` which will produce a STB_WEAK memcpy with GNU as but STB_GLOBAL
memcpy with LLVM's integrated assembler before LLVM 12. LLVM 12 (since
https://reviews.llvm.org/D90108) will error on such an overridden symbol
binding.

Use the appropriate SYM_FUNC_START_WEAK_PI instead.

While I thought I had this correct (since it actually did reject modes
like I expected during testing), Ville Syrjala from Intel pointed out
that the logic here isn't correct. max_clock refers to the max data rate
supported by the DP encoder. So, limiting it to the output of ds_clock (which
refers to the maximum dotclock of the downstream DP device) doesn't make any
sense. Additionally, since we're using the connector's bpc as the canonical BPC
we should use this in mode_valid until we support dynamically setting the bpp
based on bandwidth constraints.

https://lists.freedesktop.org/archives/dri-devel/2020-September/280276.html

For more info.

So, let's rewrite this using Ville's advice.

v2:
* Ville pointed out I mixed up the dotclock and the link rate. So fix that...
* ...and also rename all the variables in this function to be more appropriately
  labeled so I stop mixing them up.
* Reuse the bpp from the connector for now until we have dynamic bpp selection.
* Use use DIV_ROUND_UP for calculating the mode rate like i915 does, which we
  should also have been doing from the start

Ville also pointed out that I got a lot of the logic here wrong as well, whoops.
While I don't think anyone's likely using 3D output with nouveau, the next patch
will make nouveau_conn_mode_valid() make a lot less sense. So, let's just get
rid of it and open-code it like before, while taking care to move the 3D frame
packing calculations on the dot clock into the right place.

Not entirely sure why this never came up when I originally tested this
(maybe some BIOSes already have this setup?) but the ->caps_init vfunc
appears to cause the display engine to throw an exception on driver
init, at least on my ThinkPad P72:

This is magic nvidia speak for "You need to have the DMA notifier offset
programmed before you can call NV507D_GET_CAPABILITIES." So, let's fix
this by doing that, and also perform an update afterwards to prevent
racing with the GPU when reading capabilities.

v2:
* Don't just program the DMA notifier offset, make sure to actually
  perform an update
v3:
* Don't call UPDATE()
* Actually read the correct notifier fields, as apparently the
  CAPABILITIES_DONE field lives in a different location than the main
  NV_DISP_CORE_NOTIFIER_1 field. As well, 907d+ use a different
  CAPABILITIES_DONE field then pre-907d cards.
v4:
* Don't forget to check the return value of core507d_read_caps()
v5:
* Get rid of NV50_DISP_CAPS_NTFY[14], use NV50_DISP_CORE_NTFY
* Disable notifier after calling GetCapabilities()

so check for this properly in the driver. Without this, every peripheral
fails to probe resulting in boot failure.

 "Current release regressions:

   - r8169: fix forced threading conflicting with other shared
     interrupts; we tried to fix the use of raise_softirq_irqoff from an
     IRQ handler on RT by forcing hard irqs, but this driver shares
     legacy PCI IRQs so drop the _irqoff() instead

   - tipc: fix memory leak caused by a recent syzbot report fix to
     tipc_buf_append()

  Current release - bugs in new features:

   - devlink: Unlock on error in dumpit() and fix some error codes

   - net/smc: fix null pointer dereference in smc_listen_decline()

  Previous release - regressions:

   - tcp: Prevent low rmem stalls with SO_RCVLOWAT.

   - net: protect tcf_block_unbind with block lock

   - ibmveth: Fix use of ibmveth in a bridge; the self-imposed filtering
     to only send legal frames to the hypervisor was too strict

   - net: hns3: Clear the CMDQ registers before unmapping BAR region;
     incorrect cleanup order was leading to a crash

   - bnxt_en - handful of fixes to fixes:
      - Send HWRM_FUNC_RESET fw command unconditionally, even if there
        are PCIe errors being reported
      - Check abort error state in bnxt_open_nic().
      - Invoke cancel_delayed_work_sync() for PFs also.
      - Fix regression in workqueue cleanup logic in bnxt_remove_one().

   - mlxsw: Only advertise link modes supported by both driver and
     device, after removal of 56G support from the driver 56G was not
     cleared from advertised modes

   - net/smc: fix suppressed return code

  Previous release - always broken:

   - netem: fix zero division in tabledist, caused by integer overflow

   - bnxt_en: Re-write PCI BARs after PCI fatal error.

   - cxgb4: set up filter action after rewrites

   - net: ipa: command payloads already mapped

  Misc:

   - s390/ism: fix incorrect system EID, it's okay to change since it
     was added in current release

   - vsock: use ns_capable_noaudit() on socket create to suppress false
     positive audit messages"

As reported by Serge flag IRQF_NO_THREAD causes an error if the
interrupt is actually shared and the other driver(s) don't have this
flag set. This situation can occur if a PCI(e) legacy interrupt is
used in combination with forced threading.
There's no good way to deal with this properly, therefore we have to
remove flag IRQF_NO_THREAD. For fixing the original forced threading
issue switch to napi_schedule().

Currently it is possible to craft a special netlink RTM_NEWQDISC
command that can result in jitter being equal to 0x80000000. It is
enough to set the 32 bit jitter to 0x02000000 (it will later be
multiplied by 2^6) or just set the 64 bit jitter via
TCA_NETEM_JITTER64. This causes an overflow during the generation of
uniformly distributed numbers in tabledist(), which in turn leads to
division by zero (sigma != 0, but sigma * 2 is 0).

The related fragment of code needs 32-bit division - see commit
9b0ed89 ("netem: remove unnecessary 64 bit modulus"), so switching to
64 bit is not an option.

Fix the issue by keeping the value of jitter within the range that can
be adequately handled by tabledist() - [0;INT_MAX]. As negative std
deviation makes no sense, take the absolute value of the passed value
and cap it at INT_MAX. Inside tabledist(), switch to unsigned 32 bit
arithmetic in order to prevent overflows.

Jakub Kicinski brought up a concern in ibmvnic_set_mac().
ibmvnic_set_mac() does this:

	ether_addr_copy(adapter->mac_addr, addr->sa_data);
	if (adapter->state != VNIC_PROBED)
		rc = __ibmvnic_set_mac(netdev, addr->sa_data);

So if state == VNIC_PROBED, the user can assign an invalid address to
adapter->mac_addr, and ibmvnic_set_mac() will still return 0.

The fix is to validate ethernet address at the beginning of
ibmvnic_set_mac(), and move the ether_addr_copy to
the case of "adapter->state != VNIC_PROBED".

When moving the skbs from the subflow into the msk receive
queue, we must schedule there the required amount of memory.

Try to borrow the required memory from the subflow, if needed,
so that we leverage the existing TCP heuristic.

Restore RPS for ILK-M. We lost it when an extra HAS_RPS()
check appeared in intel_rps_enable().

Unfortunaltey this just makes the performance worse on my
ILK because intel_ips insists on limiting the GPU freq to
the minimum. If we don't do the RPS init then intel_ips will
not limit the frequency for whatever reason. Either it can't
get at some required information and thus makes wrong decisions,
or we mess up some weights/etc. and cause it to make the wrong
decisions when RPS init has been done, or the entire thing is
just wrong. Would require a bunch of reverse engineering to
figure out what's going on.

We are incorrectly limiting the max allocation size as per the mm
max_order, which is effectively the largest power-of-two that we can fit
in the region size. However, it's normal to setup the region or
allocator with a non-power-of-two size(for example 3G), which we should
already handle correctly, except it seems for the early too-big-check.

v2: make sure we also exercise the I915_BO_ALLOC_CONTIGUOUS path, which
is quite different, since for that we are actually limited by the
largest power-of-two that we can fit within the region size. (Chris)
