e4de00215c powerpc/32: Define an is_kernel_addr() to fix ARCH=ppc compilation
My commit 6bfd93c32a broke the ARCH=ppc
compilation by using the is_kernel_addr() macro in asm/uaccess.h.
This fixes it by defining a suitable is_kernel_addr() for ARCH=ppc.

61f5657c50 [PATCH] ppc32 CPM_UART: Fixed break send on SCC
SCC uart sends a break sequence each time it is stopped with the
CPM_CR_STOP_TX command. That means that each time an application closes the
serial device, a break is transmitted. To fix this, graceful tx stop is
issued for SCC.

e8222502ee [PATCH] powerpc: Kill _machine and hard-coded platform numbers
This removes statically assigned platform numbers and reworks the
powerpc platform probe code to use a better mechanism.  With this,
board support files can simply declare a new machine type with a
macro, and implement a probe() function that uses the flattened
device-tree to detect if they apply for a given machine.

We now have a machine_is() macro that replaces the comparisons of
_machine with the various PLATFORM_* constants.  This commit also
changes various drivers to use the new macro instead of looking at
_machine.

0a26b1364f ppc: Remove CHRP, POWER3 and POWER4 support from arch/ppc
32-bit CHRP machines are now supported only in arch/powerpc, as are
all 64-bit PowerPC processors.  This means that we don't use
Open Firmware on any platform in arch/ppc any more.

This makes PReP support a single-platform option like every other
platform support option in arch/ppc now, thus CONFIG_PPC_MULTIPLATFORM
is gone from arch/ppc.  CONFIG_PPC_PREP is the option that selects
PReP support and is generally what has replaced
CONFIG_PPC_MULTIPLATFORM within arch/ppc.

_machine is all but dead now, being #defined to 0.

Updated Makefiles, comments and Kconfig options generally to reflect
these changes.

c6622f63db powerpc: Implement accurate task and CPU time accounting
This implements accurate task and cpu time accounting for 64-bit
powerpc kernels.  Instead of accounting a whole jiffy of time to a
task on a timer interrupt because that task happened to be running at
the time, we now account time in units of timebase ticks according to
the actual time spent by the task in user mode and kernel mode.  We
also count the time spent processing hardware and software interrupts
accurately.  This is conditional on CONFIG_VIRT_CPU_ACCOUNTING.  If
that is not set, we do tick-based approximate accounting as before.

To get this accurate information, we read either the PURR (processor
utilization of resources register) on POWER5 machines, or the timebase
on other machines on

* each entry to the kernel from usermode
* each exit to usermode
* transitions between process context, hard irq context and soft irq
  context in kernel mode
* context switches.

On POWER5 systems with shared-processor logical partitioning we also
read both the PURR and the timebase at each timer interrupt and
context switch in order to determine how much time has been taken by
the hypervisor to run other partitions ("steal" time).  Unfortunately,
since we need values of the PURR on both threads at the same time to
accurately calculate the steal time, and since we can only calculate
steal time on a per-core basis, the apportioning of the steal time
between idle time (time which we ceded to the hypervisor in the idle
loop) and actual stolen time is somewhat approximate at the moment.

This is all based quite heavily on what s390 does, and it uses the
generic interfaces that were added by the s390 developers,
i.e. account_system_time(), account_user_time(), etc.

This patch doesn't add any new interfaces between the kernel and
userspace, and doesn't change the units in which time is reported to
userspace by things such as /proc/stat, /proc/<pid>/stat, getrusage(),
times(), etc.  Internally the various task and cpu times are stored in
timebase units, but they are converted to USER_HZ units (1/100th of a
second) when reported to userspace.  Some precision is therefore lost
but there should not be any accumulating error, since the internal
accumulation is at full precision.

75288c78c6 [PATCH] ppc32: Make platform devices being able to assign functions
Implemented by  modification of the .name field of the platform device,
when PDs with the
same names are to be used within different drivers, as
<device_name> -> <device_name>:<function>
Corresponding drivers should change the .name in struct device_driver to
reflect upper of course.

Added ppc_sys_device_disable/enable function set, making it easier to
disable all the inexistent/not utilized platform device way pdevs. By the
check of the "disabled" bit in the config field of ppc_sys_specs, disabled
platform devices will be either added/removed from the bus, or simply not
registered on it, depending on the time when disable/enable call asserted.

The default behaviour when nothing is disabled/enabled will be "all devices
are enabled", which is the same as before.

Also helper platform_notify_map function added, making assignment of
board-specific platform_info more consistent and generic.

1a42e53d17 [PATCH] powerpc: Migrate Xilinx Vertex support from the OCP bus to the platfom bus.
This patch only deals with the serial port definitions as there is no
support for any other xilinx IP cores in the kernel tree at the moment.

Board specific configuration moved out of virtex.[ch] and into the
xparameters.h wrapper.

This also prepares for the transition to the flattened device tree model.
When the bootloader provides a device tree generated from an xparameters.h
files, the kernel will no longer need xparameters/*.  The platform bus will
get populated with data from the device tree, and the device drivers will
be automatically connected to the devices.  Only the bootloader (or
ppcboot) will need xparameters directly.

51d3082fe6 [PATCH] powerpc: Unify udbg (#2)
This patch unifies udbg for both ppc32 and ppc64 when building the

stuff gets enriched with some ADB capabilities and btext output. In
addition, the early_init callback is now called on ppc32 as well,
approx. in the same order as ppc64 regarding device-tree manipulations.
The init sequences of ppc32 and ppc64 are getting closer, I'll unify
them in a later patch.

For now, you can force udbg to the scc using "sccdbg" or to btext using
"btextdbg" on powermacs. I'll implement a cleaner way of forcing udbg
output to something else than the autodetected OF output device in a
later patch.

d1405b8698 [PATCH] powerpc: Add OF address parsing code (#2)
Parsing addresses extracted from Open Firmware isn't a simple matter. We
have various bits of code that try to do it in various place, including
some heuristics in prom.c that pre-parse addresses at boot and fill
device-nodes "addrs", but those are dodgy at best and I want to
deprecate them. So this patch introduces a new set of routines that
should be capable of parsing most types of addresses and translating
them into CPU physical addresses. It currently works for things on PCI
busses and ISA busses and should work on "standard" busses like the root
bus or the MacIO bus that don't put funky flags in addresses. If you
have other bus types that do use funky flags, you'll have to add new bus
type translators, which is fairly easy.

a7f290dad3 [PATCH] powerpc: Merge vdso's and add vdso support to 32 bits kernel
This patch moves the vdso's to arch/powerpc, adds support for the 32
bits vdso to the 32 bits kernel, rename systemcfg (finally !), and adds
some new (still untested) routines to both vdso's: clock_gettime() with
support for CLOCK_REALTIME and CLOCK_MONOTONIC, clock_getres() (same
clocks) and get_tbfreq() for glibc to retreive the timebase frequency.

Tom,Steve: The implementation of get_tbfreq() I've done for 32 bits
returns a long long (r3, r4) not a long. This is such that if we ever
add support for >4Ghz timebases on ppc32, the userland interface won't
have to change.

I have tested gettimeofday() using some glibc patches in both ppc32 and
ppc64 kernels using 32 bits userland (I haven't had a chance to test a
64 bits userland yet, but the implementation didn't change and was
tested earlier). I haven't tested yet the new functions.

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.

	- We use BITS_PER_LONG to correctly size sigset_t
	- Remove some uneeded #includes and struct forward

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.

2ff2ae7a0d [PATCH] powerpc: Merge futex.h
This patch merges the ppc32 and ppc64 versions of futex.h, essentially
by taking the ppc64 version as the powerpc version.  The old ppc32
version did not implement the futex_atomic_op_inuser() callback (it
always returned -ENOSYS), so FUTEX_WAKE_OP would not work on ppc32.
In fact the ppc64 version of this function is almost suitable for
ppc32 as well - the only change needed is to extend ppc_asm.h with a
macro expanding to to the right pseudo-op to store a pointer (either
".long" or ".llong").

a0e60b2033 [PATCH] powerpc: Merge bitops.h
Here's a revised version.  This re-introduces the set_bits() function
from ppc64, which I removed because I thought it was unused (it exists
on no other arch).  In fact it is used in the powermac interrupt code
(but not on pSeries).

- We use LARXL/STCXL macros to generate the right (32 or 64 bit)
  instructions, similar to LDL/STL from ppc_asm.h, used in fpu.S

- ppc32 previously used a full "sync" barrier at the end of
  test_and_*_bit(), whereas ppc64 used an "isync".  The merged version
  uses "isync", since I believe that's sufficient.

- The ppc64 versions of then minix_*() bitmap functions have changed
  semantics.  Previously on ppc64, these functions were big-endian
  (that is bit 0 was the LSB in the first 64-bit, big-endian word).
  On ppc32 (and x86, for that matter, they were little-endian.  As far
  as I can tell, the big-endian usage was simply wrong - I guess
  no-one ever tried to use minixfs on ppc64.

- On ppc32 find_next_bit() and find_next_zero_bit() are no longer
  inline (they were already out-of-line on ppc64).

- For ppc64, sched_find_first_bit() has moved from mmu_context.h to
  the merged bitops.  What it was doing in mmu_context.h in the first
  place, I have no idea.

- The fls() function is now implemented using the cntlzw instruction
  on ppc64, instead of generic_fls(), as it already was on ppc32.

- For ARCH=ppc, this patch requires adding arch/powerpc/lib to the
  arch/ppc/Makefile.  This in turn requires some changes to
  arch/powerpc/lib/Makefile which didn't correctly handle ARCH=ppc.

8b150478ae [PATCH] ppc: make phys_mem_access_prot() work with pfns instead of addresses
Change the phys_mem_access_prot() function to take a pfn instead of an
address.  This allows mmap64() to work on /dev/mem for addresses above 4G
on 32-bit architectures.  We start with a pfn in mmap_mem(), so there's no
need to convert to an address; in fact, it's actively bad, since the
conversion can overflow when the address is above 4G.

Similarly fix the ppc32 page_is_ram() function to avoid a conversion to an
address by directly comparing to max_pfn.  Working with max_pfn instead of
high_memory fixes page_is_ram() to give the right answer for highmem pages.

2765ca2540 [PATCH] powerpc: Merge parport.h
Save for the header #define, ppc32 and ppc64 versions of parport.h are
identical.  This patch merges them.
