5daf9071b5 [PATCH] powerpc: merge align.c
This patch merges align.c, the result isn't quite what was in ppc64 nor
what was in ppc32 :) It should implement all the functionalities of both
though. Kumar, since you played with that in the past, I suppose you
have some test cases for verifying that it works properly before I dig
out the 601 machine ? :)

Since it's likely that I won't be able to test all scenario, code
inspection is much welcome.

de93f0d62c [PATCH] ppc: Fix boot with yaboot with ARCH=ppc
The merge of machine types broke boot with yaboot & ARCH=ppc due to the
old code still retreiving the old-syle machine type passed in by yaboot.
This patch fixes it by translating those old numbers. Since that whole
mecanism is deprecated, this is a temporary fix until ARCH=ppc uses the
new prom_init that the merged architecture now uses for both ppc32 and
ppc64 (after 2.6.15)

eb07d964b4 [PATCH] ppc32 8xx: update_mmu_cache() needs unconditional tlbie
Currently 8xx fails to boot due to endless pagefaults.

Seems the bug is exposed by the change which avoids flushing the
TLB when not necessary (in case the pte has not changed), introduced
recently:

__handle_mm_fault():

        entry = pte_mkyoung(entry);
        if (!pte_same(old_entry, entry)) {
                ptep_set_access_flags(vma, address, pte, entry, write_access);
                update_mmu_cache(vma, address, entry);
                lazy_mmu_prot_update(entry);
        } else {
                /*
                 * This is needed only for protection faults but the arch code
                 * is not yet telling us if this is a protection fault or not.
                 * This still avoids useless tlb flushes for .text page faults
                 * with threads.
                 */
                if (write_access)
                        flush_tlb_page(vma, address);
        }

The "update_mmu_cache()" call was unconditional before, which caused the TLB
to be flushed by:

        if (pfn_valid(pfn)) {
                struct page *page = pfn_to_page(pfn);
                if (!PageReserved(page)
                    && !test_bit(PG_arch_1, &page->flags)) {
                        if (vma->vm_mm == current->active_mm) {
#ifdef CONFIG_8xx
                        /* On 8xx, cache control instructions (particularly 
                         * "dcbst" from flush_dcache_icache) fault as write 
                         * operation if there is an unpopulated TLB entry 
                         * for the address in question. To workaround that, 
                         * we invalidate the TLB here, thus avoiding dcbst 
                         * misbehaviour.
                         */
                                _tlbie(address);
#endif
                                __flush_dcache_icache((void *) address);
                        } else
                                flush_dcache_icache_page(page);
                        set_bit(PG_arch_1, &page->flags);
                }

Which worked to due to pure luck: PG_arch_1 was always unset before, but
now it isnt.

The root of the problem are the changes against the 8xx TLB handlers introduced
during v2.6. What happens is the TLBMiss handlers load the zeroed pte into
the TLB, causing the TLBError handler to be invoked (thats two TLB faults per 
pagefault), which then jumps to the generic MM code to setup the pte.

The bug is that the zeroed TLB is not invalidated (the same reason
for the "dcbst" misbehaviour), resulting in infinite TLBError faults.

The "two exception" approach requires a TLB flush (to nuke the zeroed TLB)
at each PTE update for correct behaviour:

647422868e [PATCH] ppc32: Add support for handling PCI interrupts on MPC834x PCI expansion card
The MPC8349 PIBs system has a expansion board with 6 PCI slots.  We needed
to update the IDSEL interrupt mapping for it to work properly.  However,
only PCI1 is supported as the first revision of this expansion board
doesn't function properly for PCI2.  For the time being we have zero'd out
the entries for the IDSELs related to PCI2.  When a functioning expansion
board exists we can fix the table.

3ddfbcf19b [PATCH] powerpc: Consolidate asm compatibility macros
This patch consolidates macros used to generate assembly for
compatibility across different CPUs or configs.  A new header,
asm-powerpc/asm-compat.h contains the main compatibility macros.  It
uses some preprocessor magic to make the macros suitable both for use
in .S files, and in inline asm in .c files.  Headers (bitops.h,
uaccess.h, atomic.h, bug.h) which had their own such compatibility
macros are changed to use asm-compat.h.

ppc_asm.h is now for use in .S files *only*, and a #error enforces
that.  As such, we're a lot more careless about namespace pollution
here than in asm-compat.h.

While we're at it, this patch adds a call to the PPC405_ERR77 macro in
futex.h which should have had it already, but didn't.

Built and booted on pSeries, Maple and iSeries (ARCH=powerpc).  Built
for 32-bit powermac (ARCH=powerpc) and Walnut (ARCH=ppc).

26ef5c0957 [PATCH] powerpc: Merge cacheflush.h and cache.h
The ppc32 and ppc64 versions of cacheflush.h were almost identical.
The two versions of cache.h are fairly similar, except for a bunch of
register definitions in the ppc32 version which probably belong better
elsewhere.  This patch, therefore, merges both headers.  Notable
points:
	- there are several functions in cacheflush.h which exist only
on ppc32 or only on ppc64.  These are handled by #ifdef for now, but
these should probably be consolidated, along with the actual code
behind them later.
	- Confusingly, both ppc32 and ppc64 have a
flush_dcache_range(), but they're subtly different: it uses dcbf on
ppc32 and dcbst on ppc64, ppc64 has a flush_inval_dcache_range() which
uses dcbf.  These too should be merged and consolidated later.
	- Also flush_dcache_range() was defined in cacheflush.h on
ppc64, and in cache.h on ppc32.  In the merged version it's in
cacheflush.h
	- On ppc32 flush_icache_range() is a normal function from
misc.S.  On ppc64, it was wrapper, testing a feature bit before
calling __flush_icache_range() which does the actual flush.  This
patch takes the ppc64 approach, which amounts to no change on ppc32,
since CPU_FTR_COHERENT_ICACHE will never be set there, but does mean
renaming flush_icache_range() to __flush_icache_range() in
arch/ppc/kernel/misc.S and arch/powerpc/kernel/misc_32.S
	- The PReP register info from asm-ppc/cache.h has moved to
arch/ppc/platforms/prep_setup.c
	- The 8xx register info from asm-ppc/cache.h has moved to a
new asm-powerpc/reg_8xx.h, included from reg.h
	- flush_dcache_all() was defined on ppc32 (only), but was
never called (although it was exported).  Thus this patch removes it
from cacheflush.h and from ARCH=powerpc (misc_32.S) entirely.  It's
left in ARCH=ppc for now, with the prototype moved to ppc_ksyms.c.

a23414beb6 ppc/powerpc: workarounds for old Open Firmware versions
This adds code to work around some problems with old versions of
Open Firmware, such as on the early powermacs (7500 etc.) and the
"Longtrail" CHRP machine.  On these machines we have to claim
the physical and virtual address ranges explicitly when claiming
memory and then set up a V->P mapping.

The Longtrail has more problems: setprop doesn't work, and we have
to set an "allow-reclaim" variable to 0 in order to get claim on
physical memory ranges to fail if the memory is already claimed.

c5ff700116 [PATCH] powerpc: Merge signal.h
Having already merged the ppc and ppc64 versions of signal.c, this
patch finishes the job by merging signal.h.  The two versions were
almost identical already.  Notable changes:
	- We use BITS_PER_LONG to correctly size sigset_t
	- Remove some uneeded #includes and struct forward
declarations.  This does mean adding an include to signal_32.c which
relied on the indirect inclusion of sigcontext.h
	- As the ppc64 version, the merged signal.h has prototypes for
do_signal() and do_signal32().  Thus remove extra prototypes from
ppc_ksyms.c which had them directly.

64c7c8f885 [PATCH] sched: resched and cpu_idle rework
Make some changes to the NEED_RESCHED and POLLING_NRFLAG to reduce
confusion, and make their semantics rigid.  Improves efficiency of
resched_task and some cpu_idle routines.

* In resched_task:
- TIF_NEED_RESCHED is only cleared with the task's runqueue lock held,
  and as we hold it during resched_task, then there is no need for an
  atomic test and set there. The only other time this should be set is
  when the task's quantum expires, in the timer interrupt - this is
  protected against because the rq lock is irq-safe.

- If TIF_NEED_RESCHED is set, then we don't need to do anything. It
  won't get unset until the task get's schedule()d off.

- If we are running on the same CPU as the task we resched, then set
  TIF_NEED_RESCHED and no further action is required.

- If we are running on another CPU, and TIF_POLLING_NRFLAG is *not* set
  after TIF_NEED_RESCHED has been set, then we need to send an IPI.

Using these rules, we are able to remove the test and set operation in
resched_task, and make clear the previously vague semantics of
POLLING_NRFLAG.

* In idle routines:
- Enter cpu_idle with preempt disabled. When the need_resched() condition
  becomes true, explicitly call schedule(). This makes things a bit clearer
  (IMO), but haven't updated all architectures yet.

- Many do a test and clear of TIF_NEED_RESCHED for some reason. According
  to the resched_task rules, this isn't needed (and actually breaks the
  assumption that TIF_NEED_RESCHED is only cleared with the runqueue lock
  held). So remove that. Generally one less locked memory op when switching
  to the idle thread.

- Many idle routines clear TIF_POLLING_NRFLAG, and only set it in the inner
  most polling idle loops. The above resched_task semantics allow it to be
  set until before the last time need_resched() is checked before going into
  a halt requiring interrupt wakeup.

  Many idle routines simply never enter such a halt, and so POLLING_NRFLAG
  can be always left set, completely eliminating resched IPIs when rescheduling
  the idle task.

  POLLING_NRFLAG width can be increased, to reduce the chance of resched IPIs.

5bfb5d690f [PATCH] sched: disable preempt in idle tasks
Run idle threads with preempt disabled.

Also corrected a bugs in arm26's cpu_idle (make it actually call schedule()).
How did it ever work before?

Might fix the CPU hotplugging hang which Nigel Cunningham noted.

We think the bug hits if the idle thread is preempted after checking
need_resched() and before going to sleep, then the CPU offlined.

After calling stop_machine_run, the CPU eventually returns from preemption and
into the idle thread and goes to sleep.  The CPU will continue executing
previous idle and have no chance to call play_dead.

By disabling preemption until we are ready to explicitly schedule, this bug is
fixed and the idle threads generally become more robust.

8f09f4a25a [PATCH] ppc: fix-up schedule_timeout() usage
Use schedule_timeout_interruptible() instead of
set_current_state()/schedule_timeout() to reduce kernel size.  Also use
human-time conversion functions instead of hard-coded HZ division to avoid
rounding errors.

On PPC405GP/GPR it should be possible to enable PCI support, even when the
internal PCI arbiter is disabled (e.g.  when using an external PCI
arbiter).  The removed code didn't allow this, and also generated a warning
on PPC405EP platforms.

high-throughput segment and a low-latency segment).  Fix our PLB register
definitions to cope with this, and add code to dump the status of both
segments when a machine check occurs.

fcc188e7fd [PATCH] ppc32: Allow ERPN for early serial to depend on CPU type
The PowerPC 440SPe supports up to 16 GB of RAM, and therefore its IO registers
are at 0x4_xxxx_xxxx instead of being at 0x1_xxxx_xxxx like most other PPC 440
chips.  To allow for this, this patch moves the definition of the ERPN used
for mapping UART0 from being hard-coded in the head_44x.S assembly code to
being defined in ibm44x.h.
