No other architecture has setup_profiling_timer() in the init section,
thus on parisc we face this section mismatch warning:
 Reference from the function devm_device_add_group() to the function .init.text:setup_profiling_timer()

The 0-DAY kernel test infrastructure reported that inet_put_port() may
reference the find_pa_parent_type() function, so it can't be moved into the
init section.

Fix three section mismatches:
1) Section mismatch in reference from the function ioread8() to the
   function .init.text:pcibios_init_bridge()
2) Section mismatch in reference from the function free_initmem() to the
   function .init.text:map_pages()
3) Section mismatch in reference from the function ccio_ioc_init() to
   the function .init.text:count_parisc_driver()

Fix two section mismatches in drivers.c:
1) Section mismatch in reference from the function alloc_tree_node() to
   the function .init.text:create_tree_node().
2) Section mismatch in reference from the function walk_native_bus() to
   the function .init.text:alloc_pa_dev().

The read_persistent_clock() uses a timespec, which is not year 2038 safe
on 32bit systems. On parisc architecture, we have implemented generic
RTC drivers that can be used to compensate the system suspend time, but
the RTC time can not represent the nanosecond resolution, so this patch
just converts to read_persistent_clock64() with timespec64.

Debian uses "make all" to build the Linux kernel, thus to be able to use
the self-decompressing kernel as default debian kernel we need to make
bzImage the default build target.

Commit 71d577db01a5 ("parisc: Switch to generic COMPAT_BINFMT_ELF")
removed the binfmt_elf32.c source file, but missed to drop the object
file from the list of object files the Makefile, which then results in a
build error.

Pull parisc updates from Helge Deller:

 - fix panic when halting system via "shutdown -h now"

 - drop own coding in favour of generic CONFIG_COMPAT_BINFMT_ELF
   implementation

 - add FPE_CONDTRAP constant: last outstanding parisc-specific cleanup
   for Eric Biedermans siginfo patches

 - move some functions to .init and some to .text.hot linker sections

* 'parisc-4.17-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
  parisc: Prevent panic at system halt
  parisc: Switch to generic COMPAT_BINFMT_ELF
  parisc: Move cache flush functions into .text.hot section
  parisc/signal: Add FPE_CONDTRAP for conditional trap handling

When issuing a "shutdown -h now", the reboot syscall calls kernel_halt()
which shouldn't return, otherwise one gets this panic:

reboot: System halted
Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000000
CPU: 0 PID: 1 Comm: systemd-shutdow Not tainted 4.16.0-32bit+ #560

Fix it by letting machine_halt() call machine_power_off() which doesn't
return.
