Well, this is not 100% if when the card fires two consecutive
interrupts. Though unlikely, it's better to protect early than seeing
some "weird" bugs one day. I proposed attached patch. If you can help to
test, that will be appreciated (I cannot see the lockdep warning on my
box somehow).

In net/ieee80211/softmac/ieee80211softmac_wx.c, there is a bug that
prints extended sign information whenever the byte value exceeds
0x7f. The following patch changes the printk to use a u8 cast to limit
the output to 2 digits. This bug was first noticed by Dan Williams
<dcbw@redhat.com>. This patch applies to the current master branch
of the Linville tree.

Attached are two small patches for include/net/ieee80211.h to prepare
for later submission of code to implement a user-space daemon that
supplies 802.11 regulatory information.
The first change adds a bit indicating that 802.11h rules are to be
applied to a channel. As discussed earlier in this list, a single bit
is unlikely to be sufficient; however, at this time I have been unable
to find any regulations implementing differences between 802.11a and
802.11h other than DFS, radar detection and passive scanning. A single
bit is thus sufficient to convey to the driver that these rules should
be obeyed.
The second change adds comments to the freq and max_power fields of
struct ieee80211_channel to indicate the units that are used.

Hi,
this patch brings the CPCI405 board support up to date and fixes several
outstanding issues:
-add bios_fixup()
-enable RTC only when CONFIG_GEN_RTC defined
-corrected CompactPCI interrupt map
-added cpci405_early_serial_map for correct UART clocking
-removed unused code

Currently the kernel blindly halts all the processors and calls the
ibm,suspend-me rtas call. If the firmware is not in the correct
state, we then re-start all the processors and return. It is much
smarter to first check the firmware state, and only if it is waiting,
call the ibm,suspend-me call.

It seems that prom_init's early_cmdline_parse is broken on at least
Apple 970 xserves and IBM JS20 blades with SLOF. The firmware of these
machines returns -1 and 1 respectively when getprop is called for the
bootargs property of /chosen, causing Linux to ignore its builtin
command line in favor of a null string. This patch makes Linux use its
builtin command line if getprop returns an error or a null string.

Some updates to the pmac32_defconfig to make it more useful:
- Enable LSF (large single files) since we enable LBD (large block devices)
- Enable IPSEC related options
- Enable remaining raid/dm options as modules
- Disable eth1394, I doubt any has that hardware and it has a nasty habit of
auto loading first and skewing network device numbering
- Enable dummy and tun as modules, always useful to have them around
- Enable EHCI, no wonder my usb2 disk was so slow
- Enable USB storage
- Enable ext3 acls
- Disable autofs and enable autofsv4 instead
- Enable nfs v3/v4 client and server. Dont want to be left in the dark ages
of pre v3
- Enable all crypto as modules, things like cryptsetup want some of them
I havent enabled the BCM43xx, perhaps we should now?

of_node_to_nid returns -1 if the associativity cannot be found. This
means pcibus_to_cpumask has to be careful not to pass a negative index into
node_to_cpumask.
Since pcibus_to_node could be used a lot, and of_node_to_nid is slow (it
walks a list doing strcmps), lets also cache the node in the
pci_controller struct.

Instead of trying to make PPC64 MSI fit in a Intel-centric MSI layer, a
simple short-term solution is to hook the pci_{en/dis}able_msi() calls
and make a machdep call.
The rest of the MSI functions are superfluous for what is needed at this
time. Many of which can have machdep calls added as needed.
Ben and Michael Ellerman are looking into rewrite the MSI layer to be
more generic. However, in the meantime this works as a interim
solution.

The push_end macro in arch/powerpc/kernel/pci_32.c uses integer
division and multiplication to achieve the effect of rounding a
resource end address up and then advancing it to the end of a
power-of-2 sized region. This changes it to an equivalent computation
that only needs an integer add and OR. This is partly based on an
earlier patch by Mel Gorman.
