So update the minimum required version of gcc to 4.6.

Commit 0bbf47ea ("ia64: use asm-generic/io.h") results in a BUG
while booting ia64.  This is because asm-generic/io.h defines
PCI_IOBASE, which results in the function acpi_pci_root_remap_iospace()
doing a lot of unnecessary (and wrong) things.

I'd suggested an #if !CONFIG_IA64 in the functon, but Arnd suggested
keeping the fix inside the arch/ia64 tree.

Recently, ops->init() and ops->dump() of all actions were modified to
always obtain tcf_lock when accessing private action state. Actions that
don't depend on tcf_lock for synchronization with their data path use
non-bh locking API. However, tcf_lock is also used to protect rate
estimator stats in softirq context by timer callback.

Change ops->init() and ops->dump() of all actions to disable bh when using
tcf_lock to prevent deadlock reported by following lockdep warning:

Pull RISC-V updates from Palmer Dabbelt:
 "This contains some major improvements to the RISC-V port, including
  the necessary interrupt controller and timer support to actually make
  it to userspace. Support for three devices has been added:

   - the ISA-mandated timers on RISC-V systems.

   - the ISA-mandated first-level interrupt controller on RISC-V
     systems, which is handled as part of our core arch code because
     it's very small and tightly tied to the ISA.

   - SiFive's platform-level interrupt controller, which talks to the
     actual devices.

  In addition to these new devices, there are a handful of cleanups all
  over the RISC-V tree:

   - build fixes for various configurations:
      * A fix to the vDSO build's makefile so it respects CFLAGS.
      * The addition of __lshrti3, a libgcc derived function necessary
        for some 32-bit configurations.
      * !SMP && PERF_EVENTS

   - Cleanups to the arch code to remove the remnants of old versions of
     the drivers that were just properly submitted.
      * Some dead code from the timer driver, most of which wasn't ever
        even compiled.
      * Cleanups of some interrupt #defines, which are now local to the
        interrupt handling code.

   - Fixes to ptrace(), which while not being sufficient to fully make
     GDB work are at least sufficient to get simple GDB tasks to work.

   - Early printk support via RISC-V's architecturally mandated SBI
     console device.

   - A fix to our early debug trap handler to ensure it's always
     aligned.

  These patches have all been through a fairly extensive review process,
  but as this enables a whole pile of functionality (ie, userspace) I'm
  confident we'll need to submit a few more patches. The only concrete
  issues I know about are the sys_riscv_flush_icache patches, but as I
  managed to screw those up on Friday I figured it'd be best to let them
  bake another week.

  This tag boots a Fedora root filesystem on QEMU's master branch for
  me, and before this morning's rebase (from 4.18-rc8 to 4.18) it booted
  on the HiFive Unleashed.

  Thanks to Christoph Hellwig and the other guys at WD for getting the
  new drivers in shape!"

This function was created as a deprecated fallback case back in 2010 by
commit eb14120f ("pcmcia: re-work pcmcia_request_irq()") for legacy
cases.

Actual in-kernel users haven't been around for a long while.  The last
in-kernel user was apparently removed four years ago by commit
5f5316fc ("am2150: Update nmclan_cs.c to use update PCMCIA API").

Just remove it entirely.

We haven't had lots of deprecation warnings lately, but the rdma use of
it made them flare up again.

They are not useful.  They annoy everybody, and nobody ever does
anything about them, because it's always "somebody elses problem".  And
when people start thinking that warnings are normal, they stop looking
at them, and the real warnings that mean something go unnoticed.

If you want to get rid of a function, just get rid of it.  Convert every
user to the new world order.

And if you can't do that, then don't annoy everybody else with your
marking that says "I couldn't be bothered to fix this, so I'll just spam
everybody elses build logs with warnings about my laziness".

Make a kernelnewbies wiki page about things that could be cleaned up,
write a blog post about it, or talk to people on the mailing lists.  But
don't add warnings to the kernel build about cleanup that you think
should happen but you aren't doing yourself.

Don't.  Just don't.

Merge tag 'driver-core-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core updates from Greg KH:
 "Here are all of the driver core and related patches for 4.19-rc1.

  Nothing huge here, just a number of small cleanups and the ability to
  now stop the deferred probing after init happens.

  All of these have been in linux-next for a while with only a merge
  issue reported"
