Convert cpu_sibling_map to be a per cpu variable

2007-10-16T16:42:50+00:00

Convert cpu_sibling_map from a static array sized by NR_CPUS to a per_cpu
variable.  This saves sizeof(cpumask_t) * NR unused cpus.  Access is mostly
from startup and CPU HOTPLUG functions.

[POWERPC] Remove cmd_line from head*.S

2007-09-19T05:25:34+00:00

It is just a C char array, so declare it thusly.

[POWERPC] Fix Pegasos keyboard detection

2007-07-26T06:17:45+00:00

As of 2.6.22 the kernel doesn't recognize the i8042 keyboard/mouse
controller on the PegasosPPC.  This is because of a feature/bug in the
OF device tree: the "device_type" attribute is an empty string instead
of "8042" as the kernel expects.  This adds a secondary detection
which looks for a device whose *name* is "8042" if there is no device
whose *type* is "8042".

[POWERPC] Make the debugfs "powerpc" dir globally accessible

2007-07-10T11:53:50+00:00

The prom.c debugging code creates a "powerpc" directory in debugfs,
which is nice, but doesn't allow any other debugging code to stick things
under "powerpc" in debugfs. So make it global.

While we're there we should make the prom.c debugging code depend on
CONFIG_DEBUG_FS, because it doesn't work otherwise.

[POWERPC] Add a check for keyboard/mouse device nodes in check_legacy_ioport()

2007-07-10T11:53:49+00:00

The device tree for the MPC8641 HPCN does not implement the device type
property for I8042 nodes.

In addition to checking the I8042 node's device type, also match the
keyboard and/or mouse nodes' compatible property.

[POWERPC] Check cache coherency of kernel vs firmware

2007-05-12T01:32:50+00:00

check_cache_coherency() verifies that the cache coherency setting of
the kernel (CONFIG_NOT_COHERENT_CACHE) matches that left by the firmware,
as indicated by coherency-off device tree property.

[POWERPC] Generic check_legacy_ioport

2007-04-27T11:14:30+00:00

check_legacy_ioport makes only sense on PREP, CHRP and pSeries.
They may have an isa node with PS/2, parport, floppy and serial ports.

Remove the check_legacy_ioport call from ppc_md, it's not needed
anymore.  Hardware capabilities come from the device-tree.
