This changes the way we calculate how much space to reserve for the pHyp dump. Currently we reserve 256MB only. With this change, the code first checks to see if an amount has been specified on the boot command line with the "phyp_dump_reserve_size" option, and if so, uses that much. Otherwise it computes 5% of total ram and rounds it down to a multiple of 256MB, and uses the larger of that or 256MB. This is for large systems with a lot of memory (10GB or more). The aim is to have more space available for the kernel on reboot on machines with more resources. Although the dump will be collected pretty fast and the memory released really early on allowing the machine to have the full memory available, this alleviates any issues that can be caused by having way too little memory on very very large systems during those few minutes.

This changes the cpu_idle loop for 44x platforms to utilize the Wait Enable feature of the CPU. This helps virtulization solutions know when the guest Linux kernel is in an idle state. A command line option called "idle" is also added to allow people to change the idle loop back to the original variation. This is done by setting "idle=spin" on the kernel command line.

The iSeries HV only needs the first two fields of the paca statically initialised, so create an alternate paca that contains only those and switch to our real paca immediately after boot.

With a multiplatform kernel, once built we always have warp_setup_nand_flash() called and NDFC probed, no matter what machine we actually run on. This potentially can cause problems (such as kernel crash), since NDFC is probed at a warp-predefined address. Using machine_device_initcall() NAND devices are registered if we run on a warp only.

This patch creates a common system reset routine for all 40x and 44x systems. Previously only a 44x routine existed. But since this system reset via the debug control register is common for 40x and 44x let's share this code for all those platforms in ppc4xx_soc.c. This patch also enables CONFIG_4xx_SOC for all 40x and 44x platforms. Tested on Kilauea (405EX) and Canyonlands (440EX).

This patch adds support for the 256k L2 cache found on some IBM/AMCC 4xx PPC's. It introduces a common 4xx SoC file (sysdev/ppc4xx_soc.c) which currently "only" adds the L2 cache init code. Other common 4xx stuff can be added later here. The L2 cache handling code is a copy of Eugene's code in arch/ppc with small modifications. Tested on AMCC Taishan 440GX.

Check to see if there actually is data from a previously crashed kernel waiting. If so, allow user-space tools to grab the data (by reading /proc/kcore). When user-space finishes dumping a section, it must release that memory by writing to sysfs. For example, echo "0x40000000 0x10000000" > /sys/kernel/release_region will release 256MB starting at the 1GB. The released memory becomes free for general use.

Prevailing practice for define_machine() in powerpc is to use the platform name when the platform has only one define_machine() statement, but maple uses "maple_md". This caused me some head-scratching when writing some new code that uses machine_is(maple). Use "maple" instead of "maple_md". There should not be any behavioral change -- fixup_maple_ide() calls machine_is(maple) but the body of the function is ifdef'd out.

At present, we can hit the BUG_ON in __spu_update_sched_info by reading the regs file of a context between two calls to spu_run. The spu_release_saved called by spufs_regs_read() is resulting in the (now non-runnable) context being placed back on the run queue, so the next call to spu_run ends up in the bug condition. This change uses the SPU_SCHED_SPU_RUN flag to only reschedule a context if it's still in spu_run(). Signed-off-by: NJeremy Kerr <jk@ozlabs.org>
