2006-01-23[SUNGEM]: Make PM of PHYs more reliable (#2)Benjamin Herrenschmidt
On my latest laptop, I've had occasional PHY dead on wakeup from sleep... the PHY would be totally unresponsive even to toggling the hard reset line until the machine is powered down... Looking closely at the code, I found some possible issues in the way we setup the MDIO lines during suspend along with slight divergences from what Darwin does when resetting it that may explain the problem. That patch change these and the problem appear to be gone for me at least... I also fixed an mdelay -> msleep while I was at it to the pmac feature code that is called when toggling the PHY reset line since sungem doesn't call it in an atomic context anymore.

2006-01-13[PATCH] powerpc: Remove lppaca structure from the PACADavid Gibson
At present the lppaca - the structure shared with the iSeries hypervisor and phyp - is contained within the PACA, our own low-level per-cpu structure. This doesn't have to be so, the patch below removes it, making a separate array of lppaca structures. This saves approximately 500*NR_CPUS bytes of image size and kernel memory, because we don't need aligning gap between the Linux and hypervisor portions of every PACA. On the other hand it means an extra level of dereference in many accesses to the lppaca. The patch also gets rid of several places where we assign the paca address to a local variable for no particular reason.

2006-01-11[PATCH] powerpc: Make early debugging configurable via KconfigMichael Ellerman
This patch adds Kconfig entries to control the early debugging options, currently in setup_64.c. Doing this via Kconfig rather than #defines means you can have one source tree, which is buildable for multiple platforms - and you can enable the correct early debug option for each platform via .config. I made udbg_early_init() a static inline because otherwise GCC is to daft to optimise it away when debugging is off. Now that we have udbg_init_rtas() we can make call_rtas_display_status* static.

2006-01-11[PATCH] powerpc: Early debugging support for iSeriesMichael Ellerman
