Stephen Rothwell 340601043d powerpc: Add a shutdown member to vio_driver
Add a shutdown member to struct vio_driver. We also need vio_bus_shutdown()
which converts from struct device to struct vio_dev and knows how to extract
the struct vio_driver.

Original patch adjusted for different location of vio.c.

Paul Mackerras 96c4450760 powerpc: Fix time code for 601 processors
The 601 doesn't have the timebase register; instead it has an RTCL
register that counts nanoseconds and wraps at 1000000000, and an
RTCU register that counts seconds.  This makes the necessary changes
for the merged time code to use the RTCL/U registers when the kernel
is running on a 601.

Paul Mackerras 35499c0195 powerpc: Merge in 64-bit powermac support.
This brings in a lot of changes from arch/ppc64/kernel/pmac_*.c to
arch/powerpc/platforms/powermac/*.c and makes various minor tweaks
elsewhere.  On the powermac we now initialize ppc_md by copying
the whole pmac_md structure into it, which required some changes in
the ordering of initializations of individual fields of it.

David Gibson 6cb7bfebb1 [PATCH] powerpc: Merge thread_info.h
Merge ppc32 and ppc64 versions of thread_info.h.  They were pretty
similar already, the chief changes are:

	- Instead of inline asm to implement current_thread_info(),
which needs to be different for ppc32 and ppc64, we use C with an
asm("r1") register variable.  gcc turns it into the same asm as we
used to have for both platforms.
	- We replace ppc32's 'local_flags' with the ppc64
'syscall_noerror' field.  The noerror flag was in fact the only thing
in the local_flags field anyway, so the ppc64 approach is simpler, and
means we only need a load-immediate/store instead of load/mask/store
when clearing the flag.
	- In readiness for 64k pages, when THREAD_SIZE will be less
than a page, ppc64 used kmalloc() rather than get_free_pages() to
allocate the kernel stack.  With this patch we do the same for ppc32,
since there's no strong reason not to.
	- For ppc64, we no longer export THREAD_SHIFT and THREAD_SIZE
via asm-offsets, thread_info.h can now be safely included in asm, as
on ppc32.

Built and booted on G4 Powerbook (ARCH=ppc and ARCH=powerpc) and
Power5 (ARCH=ppc64 and ARCH=powerpc).

I had the sense of the test for when to use the old 601-style RTC
registers inverted.  pmac_calibrate_decr and via_calibrate_decr
weren't setting ppc_tb_freq, on which all the further calculations
depended.  Lastly, update_gtod was losing the top 32 bits of

Benjamin Herrenschmidt cbd27b8ced [PATCH] ppc32: Fix timekeeping
Interestingly enough, ppc32 had broken timekeeping for ages...  It
worked, but probably drifted a bit more than could be explained by the
actual bad precision of the timebase calibration.  We discovered that
recently when somebody figured out that the common code was using
CLOCK_TICK_RATE to correct the timekeeing, and ppc32 had a completely
bogus value for it.

This patch turns it into something saner.  Probably not as good as doing
something based on the actual timebase frequency precision but I'll
leave that sort of math to others.  This at least makes it better for
the common HZ values.

Merge elf.h into a single include file for 32 and 64-bit ppc platforms. This
patch has been tested on 32-bit and built on 64-bit platforms.

ppc32/ppc64: Merge bug.h into include/asm-powerpc

This patch merges bug.h into include/asm-powerpc.  Changed the data
structure for bug_entry such that line is always an int on both 32 and
64-bit platforms; removed casts to int from the 64-bit trap code to
reflect this.

linuxppc@jdl.com 3e57615bb5 [PATCH] powerpc: Revised merge asm-ppc*/hardirq.h
This is a revised patch to merge asm-ppc*/hardirq.h.
It removes some unnecessary #includes, but then requires
the addition of #include <asm/irq.h> in PPC32's hw_irq.h
much like ppc64 already does.  Furthermore, several
unnecessary #includes were removed from some ppc32 boards
in order to break resulting bad #include cycles.

Builds pSeries_defconfig and all ppc32 platforms except
the already b0rken bseip.

Merged ppc_asm.h between ppc32 & ppc64.  The majority of the file is
common between the two architectures excluding how a single GPR is
saved/restored and which GPRs are non-volatile.

Additionally, moved the ASM_CONST macro used on ppc64 into ppc_asm.h.

Anton Blanchard a94d308513 [PATCH] ppc64: Add definitions for new PTRACE calls
- Add PTRACE_GET_DEBUGREG/PTRACE_SET_DEBUGREG. The definition is
  as follows:

/*
 * Get or set a debug register. The first 16 are DABR registers and the
 * second 16 are IABR registers.
 */
#define PTRACE_GET_DEBUGREG    25
#define PTRACE_SET_DEBUGREG    26

  DABR == data breakpoint and IABR = instruction breakpoint in IBM
  speak. We could split out the IABR into 2 more ptrace calls but I
  figured there was no need and 16 DABR registers should be more
  than enough (POWER4/POWER5 have one).

- Add 2 new SIGTRAP si_codes: TRAP_HWBKPT and TRAP_BRANCH. I couldnt
  find any standards on either of these so I copied what ia64 is
  doing. Again this might be better placed in
  include/asm-generic/siginfo.h

The ppc and ppc64 trees are hopefully going to merge over time, so this

Create include/asm-powerpc (and move linkage.h into it from

ppc and ppc64 Makefiles to cope.
