  watchdog: move softlockup_panic back to early_param (2023-11-01 12:10:02 -0700)

sysctl-6.7-rc1

To help make the move of sysctls out of kernel/sysctl.c not incur a size
penalty sysctl has been changed to allow us to not require the sentinel, the
final empty element on the sysctl array. Joel Granados has been doing all this
work. On the v6.6 kernel we got the major infrastructure changes required to
support this. For v6.7-rc1 we have all arch/ and drivers/ modified to remove
the sentinel. Both arch and driver changes have been on linux-next for a bit
less than a month. It is worth re-iterating the value:

  - this helps reduce the overall build time size of the kernel and run time
     memory consumed by the kernel by about ~64 bytes per array
  - the extra 64-byte penalty is no longer inncurred now when we move sysctls
    out from kernel/sysctl.c to their own files

For v6.8-rc1 expect removal of all the sentinels and also then the unneeded
check for procname == NULL.

The last 2 patches are fixes recently merged by Krister Johansen which allow
us again to use softlockup_panic early on boot. This used to work but the
alias work broke it. This is useful for folks who want to detect softlockups
super early rather than wait and spend money on cloud solutions with nothing
but an eventual hung kernel. Although this hadn't gone through linux-next it's
also a stable fix, so we might as well roll through the fixes now.
