Hello,

Here is an assorted collection of fixes for W=1.

After this series, only a few errors are left, some missing declarations
in arch/powerpc/kernel/sys_ppc32.c, panic_smp_self_stop() declaration
and a few of these which I don't know how to fix :

  ./arch/powerpc/xmon/xmon.c: In function ‘xmon_print_symbol’:
  ./arch/powerpc/xmon/xmon.c:3656:14: error: variable ‘name’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Werror=clobbered]
   3656 |  const char *name = NULL;
        |              ^~~~

Cheers,

C. 

Changes in v2 :

 - improved commit logs
 - reworked some changes to reduce the number of lines. 
 - fixed misuse of asm/asm-prototypes.h for soft_nmi_interrupt()

The last use of 'status' was removed in 2012. Remove the variable to
fix this W=1 compile error.

pseries_pcibios_bus_add_device() is a local routine defining the
pcibios_bus_add_device() handler of the pseries machine in
eeh_pseries_init(). It doesn't need to be external.

It fixes this W=1 compile error:

debugger_ipi_callback() is a local routine used as a NMI IPI handler and
does not need to be external.

It fixes this W=1 compile error :

../arch/powerpc/kernel/smp.c:579:6: error: no previous prototype for ‘debugger_ipi_callback’ [-Werror=missing-prototypes]

data type") removed the use of patch_imm32_load_insns(). Clean it up
to fix this W=1 compile error :

soft_nmi_interrupt() usage requires PPC_WATCHDOG to be configured.
Check the CONFIG definition to declare the prototype.

It fixes this W=1 compile error :

../arch/powerpc/kernel/watchdog.c:250:6: error: no previous prototype for ‘soft_nmi_interrupt’ [-Werror=missing-prototypes]
  250 | void soft_nmi_interrupt(struct pt_regs *regs)

Only used locally. It fixes this W=1 compile error :

../arch/powerpc/platforms/pseries/eeh_pseries.c:697:5: error: no previous prototype for ‘pseries_send_allow_unfreeze’ [-Werror=missing-prototypes]
  697 | int pseries_send_allow_unfreeze(struct pci_dn *pdn,
      |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~
