powerpc: Remove arch/ppc and include/asm-ppc

2008-06-10T11:40:22+00:00

All the maintained platforms are now in arch/powerpc, so the old
arch/ppc stuff can now go away.

[PPC] Remove 85xx from arch/ppc

2008-01-28T14:33:10+00:00

85xx exists in arch/powerpc as well as cuImage support to boot from
a u-boot that doesn't support device trees.

rename thread_info to stack

2007-05-09T19:30:56+00:00

This finally renames the thread_info field in task structure to stack, so that
the assumptions about this field are gone and archs have more freedom about
placing the thread_info structure.

Nonbroken archs which have a proper thread pointer can do the access to both
current thread and task structure via a single pointer.

It'll allow for a few more cleanups of the fork code, from which e.g.  ia64
could benefit.

ppc: Fix typo in TI_LOCAL_FLAGS definition

2006-05-28T22:42:34+00:00

A typo crept in with commit ea1e847cc202e805769c3c46ba5e5c53714068a1
which defined TI_LOCAL_FLAGS to be the offset of the `flags' field
of struct thread_info, rather than the `local_flags' field.  This
fixes it.  The typo was pointed out by Guennadi Liakhovetski.

[PATCH] ppc: Fix powersave code on arch/ppc

2006-04-21T12:33:22+00:00

Fix asm_offsets.c and entry.S to work with the new power save code.
Changes in arch/powerpc needed to exist in arch/ppc as well since the
idle code is shared by both ppc and powerpc..

powerpc: Fix various syscall/signal/swapcontext bugs

2006-03-08T02:24:22+00:00

A careful reading of the recent changes to the system call entry/exit
paths revealed several problems, plus some things that could be
simplified and improved:

* 32-bit wasn't testing the _TIF_NOERROR bit in the syscall fast exit
  path, so it was only doing anything with it once it saw some other
  bit being set.  In other words, the noerror behaviour would apply to
  the next system call where we had to reschedule or deliver a signal,
  which is not necessarily the current system call.

* 32-bit wasn't doing the call to ptrace_notify in the syscall exit
  path when the _TIF_SINGLESTEP bit was set.

* _TIF_RESTOREALL was in both _TIF_USER_WORK_MASK and
  _TIF_PERSYSCALL_MASK, which is odd since _TIF_RESTOREALL is only set
  by system calls.  I took it out of _TIF_USER_WORK_MASK.

* On 64-bit, _TIF_RESTOREALL wasn't causing the non-volatile registers
  to be restored (unless perhaps a signal was delivered or the syscall
  was traced or single-stepped).  Thus the non-volatile registers
  weren't restored on exit from a signal handler.  We probably got
  away with it mostly because signal handlers written in C wouldn't
  alter the non-volatile registers.

* On 32-bit I simplified the code and made it more like 64-bit by
  making the syscall exit path jump to ret_from_except to handle
  preemption and signal delivery.

* 32-bit was calling do_signal unnecessarily when _TIF_RESTOREALL was
  set - but I think because of that 32-bit was actually restoring the
  non-volatile registers on exit from a signal handler.

* I changed the order of enabling interrupts and saving the
  non-volatile registers before calling do_syscall_trace_leave; now we
  enable interrupts first.

[PATCH] ppc: Make ARCH=ppc build again with new syscall path

2006-01-09T03:50:55+00:00

This makes ARCH=ppc build in your powerpc tree again, with the new
syscall entry/exit path.

Still doesn't actually boot on my Pegasos; the last thing I see is
'MMU:exit'. But at least it builds -- I'll look at why it doesn't boot
later, so that I can see if the mv643xx_eth actually works with ARCH=ppc
(it doesn't with ARCH=powerpc; two in every three packets I receive are
offset by 4 bytes).
