[PATCH] powerpc: properly configure DDR/P5IOC children devs

2006-03-16T05:55:07+00:00

The dynamic add path for PCI Host Bridges can fail to configure children
adapters under P5IOC controllers.  It fails to properly fixup bus/device
resources, and it fails to properly enable EEH.  Both of these steps
need to occur before any children devices are enabled in
pci_bus_add_devices().

[PATCH] powerpc: remove duplicate EXPORT_SYMBOLS

remove warnings when building a 64bit kernel.
smp_call_function triggers also with 32bit kernel.

[PATCH] powerpc: RTC memory corruption

2006-03-16T05:55:03+00:00

We should be memset'ing the data we are pointing to, not the pointer
itself.  This is in an error path so we probably don't hit it much.

[PATCH] powerpc: enable NAP only on cpus who support it to avoid memory corruption

2006-03-16T05:55:02+00:00

This patch fixes incorrect setting of powersave_nap to 1 on all
PowerMacs, potentially causing memory corruption on some models. This
bug was introuced by me during the 32/64 bits merge.

[PATCH] powerpc: Clarify wording for CRASH_DUMP Kconfig option

2006-03-16T05:55:00+00:00

The wording of the CRASH_DUMP Kconfig option is not very clear. It gives you a
kernel that can be used _as_ the kdump kernel, not a kernel that can boot into
a kdump kernel.

[PATCH] powerpc/64: enable CONFIG_BLK_DEV_SL82C105

2006-03-16T05:54:59+00:00

Enable the onboard IDE driver for p610, p615 and p630.
They have the CD connected to this card. All other RS/6000 systems with this
controller have no connectors and dont need this option.

[PATCH] powerpc: correct cacheflush loop in zImage

2006-03-16T05:54:57+00:00

Correct the loop for cacheflush. No idea where I copied the code from,
but the original does not work correct. Maybe the flush is not needed.

powerpc: Fix problem with time going backwards

2006-03-16T05:54:55+00:00

The recent changes to keep gettimeofday in sync with xtime had the side
effect that it was occasionally possible for the time reported by
gettimeofday to go back by a microsecond.  There were two reasons:
(1) when we recalculated the offsets used by gettimeofday every 2^31
timebase ticks, we lost an accumulated fractional microsecond, and
(2) because the update is done some time after the notional start of
jiffy, if ntp is slowing the clock, it is possible to see time go backwards
when the timebase factor gets reduced.

This fixes it by (a) slowing the gettimeofday clock by about 1us in
2^31 timebase ticks (a factor of less than 1 in 3.7 million), and (b)
adjusting the timebase offsets in the rare case that the gettimeofday
result could possibly go backwards (i.e. when ntp is slowing the clock
and the timer interrupt is late).  In this case the adjustment will
reduce to zero eventually because of (a).

powerpc: Disallow lparcfg being a module

2006-03-14T00:35:37+00:00

The lparcfg code needs several things which are pretty arcane internal
details and which we don't want to export, which means that lparcfg
doesn't work when built as a module.  This makes it a bool instead of
a tristate in the Kconfig so that users can't try to build it as a
module.
