6761a0ae98 Char/Misc driver fixes for 5.15-rc4
Here are some small misc driver fixes for 5.15-rc4.  They are in two
 "groups":
 	- ipack driver fixes for issues found by Johan Hovold
 	- interconnect driver fixes for reported problems
 
 All of these have been in linux-next for a while with no reported
 issues.

9bc62afe03 Networking fixes for 5.15-rc3.
Current release - regressions:
 
  - dsa: bcm_sf2: fix array overrun in bcm_sf2_num_active_ports()
 
 Previous releases - regressions:
 
  - introduce a shutdown method to mdio device drivers, and make DSA
    switch drivers compatible with masters disappearing on shutdown;
    preventing infinite reference wait
 
  - fix issues in mdiobus users related to ->shutdown vs ->remove
 
  - virtio-net: fix pages leaking when building skb in big mode
 
  - xen-netback: correct success/error reporting for the SKB-with-fraglist
 
  - dsa: tear down devlink port regions when tearing down the devlink
         port on error
 
  - nexthop: fix division by zero while replacing a resilient group
 
  - hns3: check queue, vf, vlan ids range before using
 
 Previous releases - always broken:
 
  - napi: fix race against netpoll causing NAPI getting stuck
 
  - mlx4_en: ensure link operstate is updated even if link comes up
             before netdev registration
 
  - bnxt_en: fix TX timeout when TX ring size is set to the smallest
 
  - enetc: fix illegal access when reading affinity_hint;
           prevent oops on sysfs access
 
  - mtk_eth_soc: avoid creating duplicate offload entries
 
 Misc:
 
  - core: correct the sock::sk_lock.owned lockdep annotations

316346243b Merge branch 'gcc-min-version-5.1' (make gcc-5.1 the minimum version)
Merge patch series from Nick Desaulniers to update the minimum gcc
version to 5.1.

This is some of the left-overs from the merge window that I didn't want
to deal with yesterday, so it comes in after -rc1 but was sent before.

Gcc-4.9 support has been an annoyance for some time, and with -Werror I
had the choice of applying a fairly big patch from Kees Cook to remove a
fair number of initializer warnings (still leaving some), or this patch
series from Nick that just removes the source of the problem.

The initializer cleanups might still be worth it regardless, but
honestly, I preferred just tackling the problem with gcc-4.9 head-on.
We've been more aggressiuve about no longer having to care about
compilers that were released a long time ago, and I think it's been a
good thing.

I added a couple of patches on top to sort out a few left-overs now that
we no longer support gcc-4.x.

As noted by Arnd, as a result of this minimum compiler version upgrade
we can probably change our use of '--std=gnu89' to '--std=gnu11', and
finally start using local loop declarations etc.  But this series does
_not_ yet do that.

76ae847497 Documentation: raise minimum supported version of GCC to 5.1
commit fad7cd3310 ("nbd: add the check to prevent overflow in
__nbd_ioctl()") raised an issue from the fallback helpers added in
commit f0907827a8 ("compiler.h: enable builtin overflow checkers and
add fallback code")

Specifically, the helpers for checking whether the results of a
multiplication overflowed (__unsigned_mul_overflow,
__signed_add_overflow) use the division operator when
!COMPILER_HAS_GENERIC_BUILTIN_OVERFLOW.  This is problematic for 64b
operands on 32b hosts.

Also, because the macro is type agnostic, it is very difficult to write
a similarly type generic macro that dispatches to one of:
 * div64_s64
 * div64_u64
 * div_s64
 * div_u64

Raising the minimum supported versions allows us to remove all of the
fallback helpers for !COMPILER_HAS_GENERIC_BUILTIN_OVERFLOW, instead
dispatching the compiler builtins.

arm64 has already raised the minimum supported GCC version to 5.1, do
this for all targets now.  See the link below for the previous
discussion.

riscv: Improve stack randomisation on RV64
This enlarges the bits availiable for stack randomisation on RV64 from
the default of 8MiB to 1GiB, to match arm64 and x86.

Also, update the documentation to reflect our support for stack
randomisation.

5ffc06ebea Misc driver patches for 5.15-rc1, second round
Here is a second round of misc driver patches for 5.15-rc1.
 
 In here is only updates for the Habanalabs driver.  This request is late
 because the previously-objected-to dma-buf patches are all removed and
 some fixes that you and others found are now included in here as well.
 
 All of these have been in linux-next for well over a week with no
 reports of problems, and they are all self-contained to only this one
 driver.  Full details are in the shortlog.
