One of the gratuitous difference between 32 and 64-bit ptrace is
whether you can whack the MSR:FE0 and FE1 bits from ptrace. This
patch forbids it unconditionally. In addition, the 64-bit kernels
used to return the exception mode in the MSR on reads, but 32-bit
kernels didn't. This patch makes it return those bits on both.
Finally, since ptrace-ppc32.h and ptrace-ppc64.h are mostly empty now, and
since the previous patch made ptrace32.c no longer need the MSR_DEBUGCHANGE
definition, we just remove those 2 files and move back the remaining bits
to ptrace.c (they were short lived heh ?).

[POWERPC] Allow ptrace write to pt_regs trap and orig_r3
This patch allows a ptracer to write to the "trap" and "orig_r3" words
of the pt_regs.
This, along with a subsequent patch to the signal restart code, should
enable gdb to properly handle syscall restarting after executing a separate
function (at least when there's no restart block).
This patch also removes ptrace32.c code toying directly with the registers
and makes it use the ptrace_get/put_reg() accessors for everything so that
the logic for checking what is permitted is in only one place.

The powerpc ptrace interface is dodgy at best. We have defined our
"own" versions of GETREGS/SETREGS/GETFPREGS/SETFPREGS that strangely
take arguments in reverse order from other archs (in addition to having
different request numbers) and have subtle issue, like not accessing
all of the registers in their respective categories.
This patch moves the implementation of those to a separate function
in order to facilitate their deprecation in the future, and provides
new ptrace requests that mirror the x86 and sparc ones and use the
same numbers:
PTRACE_GETREGS : returns an entire pt_regs (the whole thing,
not only the 32 GPRs, though that doesn't
include the FPRs etc... There's a compat version
for 32 bits that returns a 32 bits compatible
pt_regs (44 uints)
PTRACE_SETREGS : sets an entire pt_regs (the whole thing,
not only the 32 GPRs, though that doesn't
include the FPRs etc... Some registers cannot be
written to and will just be dropped, this is the
same as with POKEUSR, that is anything above MQ
on 32 bits and CCR on 64 bits. There is a compat
version as well.
PTRACE_GETFPREGS : returns all the FP registers -including- the FPSCR
that is 33 doubles (regardless of 32/64 bits)
PTRACE_SETFPREGS : sets all the FP registers -including- the FPSCR
that is 33 doubles (regardless of 32/64 bits)
And two that only exist on 64 bits kernels:
PTRACE_GETREGS64 : Same as PTRACE_GETREGS, except there is no compat
function, a 32 bits process will obtain the full 64
bits registers
PTRACE_SETREGS64 : Same as PTRACE_SETREGS, except there is no compat
function, a 32 bits process will set the full 64
bits registers
The two later ones makes things easier to have a 32 bits debugger on a
64 bits program (or on a 32 bits program that uses the full 64 bits of
the GPRs, which is possible though has issues that will be fixed in a
later patch).
Finally, while at it, the patch removes a whole bunch of code duplication
between ptrace32.c and ptrace.c, in large part by having the former call
into the later for all requests that don't need any special "compat"
treatment.

The powerpc ptrace code has some weirdness, like a ptrace-common.h file that
is actually ppc64 only and some of the 32 bits code ifdef'ed inside ptrace.c.
There are also separate implementations for things like get/set_vrregs for
32 and 64 bits which is totally unnecessary.
This patch cleans that up a bit by having a ptrace-common.h which contains
really common code (and makes a lot more code common), and ptrace-ppc32.h and
ptrace-ppc64.h files that contain the few remaining different bits.

[POWERPC] Rewrite IO allocation & mapping on powerpc64
This rewrites pretty much from scratch the handling of MMIO and PIO
space allocations on powerpc64. The main goals are:
- Get rid of imalloc and use more common code where possible
- Simplify the current mess so that PIO space is allocated and
mapped in a single place for PCI bridges
- Handle allocation constraints of PIO for all bridges including
hot plugged ones within the 2GB space reserved for IO ports,
so that devices on hotplugged busses will now work with drivers
that assume IO ports fit in an int.
- Cleanup and separate tracking of the ISA space in the reserved
low 64K of IO space. No ISA -> Nothing mapped there.
I booted a cell blade with IDE on PIO and MMIO and a dual G5 so
far, that's it :-)
With this patch, all allocations are done using the code in
mm/vmalloc.c, though we use the low level __get_vm_area with
explicit start/stop constraints in order to manage separate
areas for vmalloc/vmap, ioremap, and PCI IOs.
This greatly simplifies a lot of things, as you can see in the
diffstat of that patch :-)
A new pair of functions pcibios_map/unmap_io_space() now replace
all of the previous code that used to manipulate PCI IOs space.
The allocation is done at mapping time, which is now called from
scan_phb's, just before the devices are probed (instead of after,
which is by itself a bug fix). The only other caller is the PCI
hotplug code for hot adding PCI-PCI bridges (slots).
imalloc is gone, as is the "sub-allocation" thing, but I do beleive
that hotplug should still work in the sense that the space allocation
is always done by the PHB, but if you unmap a child bus of this PHB
(which seems to be possible), then the code should properly tear
down all the HPTE mappings for that area of the PHB allocated IO space.
I now always reserve the first 64K of IO space for the bridge with
the ISA bus on it. I have moved the code for tracking ISA in a separate
file which should also make it smarter if we ever are capable of
hot unplugging or re-plugging an ISA bridge.
This should have a side effect on platforms like powermac where VGA IOs
will no longer work. This is done on purpose though as they would have
worked semi-randomly before. The idea at this point is to isolate drivers
that might need to access those and fix them by providing a proper
function to obtain an offset to the legacy IOs of a given bus.

For regular files in sysfs, sysfs_readdir wants to traverse
sysfs_dirent->s_dentry->d_inode->i_ino to get to the inode number.
But, the dentry can be reclaimed under memory pressure, and there is
no synchronization with readdir. This patch follows Tejun's scheme of
allocating and storing an inode number in the new s_ino member of a
sysfs_dirent, when dirents are created, and retrieving it from there
for readdir, so that the pointer chain doesn't have to be traversed.
Tejun's upstream patch uses a new-ish "ida" allocator which brings
along some extra complexity; this -stable patch has a brain-dead
incrementing counter which does not guarantee uniqueness, but because
sysfs doesn't hash inodes as iunique expects, uniqueness wasn't
guaranteed today anyway.

Update signal quality before the locked scan result translation loop,
because calling libertas_prepare_and_send_command() with the
'waitforrsp' option grabs adapter->lock in the command return processing,
leading to the deadlock.

[PATCH] libertas: make association paths consistent
The BSS to associate with (in either Infrastructure or IBSS join
operations) is now stored in _one_ place in the association request (the
bss member), not two places as before (pattemptedbss and
curbssparams->bssdescriptor).
Association requests are passed to the necessary association functions
to (a) give them access to the bss member and (b) ensure that
association/join/start setup uses settings from the request, not the
current adapter settings (which may not be valid for the requested
settings).
Because the 'bss' member of the association request is used now, the
command return functions from associate and adhoc join/start need access
to the in-progress association request to update curbssparams when
everything is done. The association worker moves the request from
pending to in-progress for the duration of the association attempt.

Handle channel changes through the deferred association framework

Do not clear the scan list except under specific conditions, such as
when (a) user-requested, or (b) joining/starting an adhoc network.
Furthermore, only clear entries which match the SSID or BSSID of the
request, not the whole scan list.

[PATCH] libertas: remove unused variables in wlan_dev_t
Actually, this patch removev wlan_dev_t totally and puts the used variables
of it directly into wlan_private. That reduces one level of indirection and
looks a little bit simpler. It's now "priv->card" and not
"priv->wlan_dev.card" and "priv->dev" instead of "priv->wlan_dev.netdev"
Changed two occurences of "((wlan_private *) dev->priv)->wlan_dev.netdev"
into "dev", because I didn't see the point in doing pointer-ping-pong.
The variables "ioport", "upld_rcv" and "upld_type" where unused. They have
been removed.
