Previously, one would have to specifically choose CONFIG_OLPC and
CONFIG_PCI_GOOLPC in order to enable PCI_OLPC. That doesn't really work
for distro kernels, so this patch allows one to choose CONFIG_OLPC and
CONFIG_PCI_GOANY in order to build in OLPC support in a generic kernel (as
requested by Robert Millan).
This also moves GOOLPC before GOANY in the menuconfig list.
Finally, make pci_access_init return early if we detect OLPC hardware.
There's no need to continue probing stuff, and pci_pcbios_init
specifically trashes our settings (we didn't run into that before because
PCI_GOANY wasn't supported).

WPA requires that the PTK is installed immediately after the 4-way handshake
in order to properly decrypt the subsequent incoming EAPOL-GTK frame. If the
PTK is not enabled by the time the EAPOL-GTK frame arrives, the frame is
dropped and the supplicant does not receive the group key.
This will happen with fast Access Points that send the EAPOL-GTK frame before
the suplicant has successfully installed and enabled the PTK. To mitigate
this situation, this patch simplifies and accelerates the SIOCSIWENCODEEXT
execution.

The RTC code that was tacked in there defines an arch_initcall;
meanwhile, the code also has a module_init function that conflicts w/
the RTC initcall. The RTC code should probably be separated or..
something. For now, just don't allow modular building of olpc-pm.

This config has the config snippets that an XO requires. Everything's
modular, as well. This can be combined w/ a generic distro config, or
to a minimalist, super-optimized config for a tiny kernel.

As per OLPC trac #7981, we need a fastpath method to enable/disable
all events via a single EC command to decrease resume latency time.
This patch adds an "all" file to /sys/power/wakeup_events that
provides this capability. Writing 1 to this file will enable
all SCI events, writing 0 will disable them all.

As per OLPC Trac #7603, this enables group scheduling in the
kernel to improve audio performance, specifically that of TamTamMini.
This is not a fix as such as it does not rootcause the issue in
the scheduler changes from 2.6.22 to 2.6.25, but it is a
working solution that allows us to improve audio quality
while we dig deeper.

commit d70b67c8bc72ee23b55381bd6a884f4796692f77 upstream
Lookup can install a child dentry for a deleted directory. This keeps
the directory dentry alive, and the inode pinned in the cache and on
disk, even after all external references have gone away.
This isn't a big problem normally, since memory pressure or umount
will clear out the directory dentry and its children, releasing the
inode. But for UBIFS this causes problems because its orphan area can
overflow.
Fix this by returning ENOENT for all lookups on a S_DEAD directory
before creating a child dentry.
Thanks to Zoltan Sogor for noticing this while testing UBIFS, and
Artem for the excellent analysis of the problem and testing.

commit d1f114d12bb4db3147e1b1342ae31083c5a79c84 upstream
This patch (as1097) fixes a bug in the remote-wakeup handling in
ehci-hcd. The driver currently does not keep track of whether the
change-suspend feature is enabled for each port; the feature is
automatically reset the first time it is read. But recent changes to
the hub driver require that the feature be read at least twice in
order to work properly.
A bit-vector is added for storing the change-suspend feature values.

My laptop thinks that it's a good idea to give -73C as the critical

commit 7efd52a407bed6a2b02015b8ebbff7beba155392 upstream
If acpi_install_notify_handler() for a bay device fails, the bay driver is
superfluous. Most likely, another driver (like libata) is already caring
about this device anyway. Furthermore,
register_hotplug_dock_device(acpi_handle) from the dock driver must not be
called twice with the same handler. This would result in an endless loop
consuming 100% of CPU. So clean up and exit.

commit 0607fd02587a6b4b086dc746d63123c1f284db68 upstream
I received a complaint that some FAT formated medias (e.g. sd memory cards)
trigger a "unknown partition table" message even though there is no partition
table and they work correctly, while in general (when e.g. formated with
mkdosfs or even Windows Vista) this message is not shown.
Currently this seems only to happen when the medias get formatted with Windows
XP (and possibly Win 2000). Then the boot indicator byte contains garbage
(part of text message) and so do the other parts checked by msdos_paritition
which then later triggers this message.
References: novell bug #364365
Most fat formatted media without partition table contains zeros in the boot
indication and the other tested bytes and so falls through the checks in
msdos_partition, leading it to return with 1 (all is fine).
But some (e.g. WinXP formatted) fat fomated medias don't use boot_ind and so
the check fails and causes a "unkown partition table" warning eventhough there
is none and everything would be fine.
This additional check directly verifies if there is a fat formatted medium
without a partition table.

commit 73f20e58b1d586e9f6d3ddc3aad872829aca7743 upstream
The on-disk media specification field in FAT is only 8-bits, so testing for
<=0xff is pointless, and can generate a "comparison is always true due to
limited range of data type" warning.
While we're there, convert FAT_VALID_MEDIA() into a C function - the present
implementation is buggy: it generates either one or two references to its
argument.
