Geert Uytterhoeven 053b514295 m68k: atari: Rename shifter to shifter_st to avoid conflict
When test-compiling the BCM2835 pin control driver on m68k:

     # define shifter ((*(volatile struct SHIFTER *)SHF_BAS))

"shifter" is a too generic name for a global definition.

As the corresponding definition for Atari TT is already called
"shifter_tt", fix this by renaming the definition for Atari ST to
"shifter_st".

Arnd Bergmann d7de1c3af1 m68k: Remove unused set_clock_mmss() helpers
Commit 397ac99c6c ("m68k: remove dead timer code") removed set_rtc_mmss()
because it was unused in 2012. However, this was itself the only user of the
mach_set_clock_mmss() callback and the many implementations of that callback,
which are equally unused.

This removes all of those as well.

Geert Uytterhoeven 6d7919a7ba m68k/atari: Modernize printing of kernel messages
- Convert from printk() to pr_*(),
  - Add missing continuations, to fix user-visible breakage,
  - Drop useless WARNING prefix,
  - Move trailing spaces to start of continuations.

Note that the "Keyboard overrun" message will now only be generated when
the kernel has been compiled for debugging.

Stephen Warren c8d5ba1891 m68k: set arch_gettimeoffset directly
remove m68k's mach_gettimeoffset function pointer, and instead directly
set the arch_gettimeoffset function pointer. This requires multiplying
all function results by 1000, since the removed m68k_gettimeoffset() did
this. Also, s/unsigned long/u32/ just to make the function prototypes
exactly match that of arch_gettimeoffset.

Passing the address of a variable as an operand to an asm statement
doesn't mark the value of this variable as used, so gcc may optimize its

Al Viro 2850bc2737 [PATCH] m68k pt_regs fixes
m68k_handle_int() split in two functions: __m68k_handle_int() takes
pt_regs * and does set_irq_regs(); m68k_handle_int() doesn't get pt_regs
*.

Places where we used to call m68k_handle_int() recursively with the same
pt_regs have simply lost the second argument, the rest is switched to
__m68k_handle_int().

The rest of patch is just dropping pt_regs * where needed.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
