The ppc32 and ppc64 versions of cacheflush.h were almost identical. The two versions of cache.h are fairly similar, except for a bunch of register definitions in the ppc32 version which probably belong better elsewhere. This patch, therefore, merges both headers. Notable points: - there are several functions in cacheflush.h which exist only on ppc32 or only on ppc64. These are handled by #ifdef for now, but these should probably be consolidated, along with the actual code behind them later. - Confusingly, both ppc32 and ppc64 have a flush_dcache_range(), but they're subtly different: it uses dcbf on ppc32 and dcbst on ppc64, ppc64 has a flush_inval_dcache_range() which uses dcbf. These too should be merged and consolidated later. - Also flush_dcache_range() was defined in cacheflush.h on ppc64, and in cache.h on ppc32. In the merged version it's in cacheflush.h - On ppc32 flush_icache_range() is a normal function from misc.S. On ppc64, it was wrapper, testing a feature bit before calling __flush_icache_range() which does the actual flush. This patch takes the ppc64 approach, which amounts to no change on ppc32, since CPU_FTR_COHERENT_ICACHE will never be set there, but does mean renaming flush_icache_range() to __flush_icache_range() in arch/ppc/kernel/misc.S and arch/powerpc/kernel/misc_32.S - The PReP register info from asm-ppc/cache.h has moved to arch/ppc/platforms/prep_setup.c - The 8xx register info from asm-ppc/cache.h has moved to a new asm-powerpc/reg_8xx.h, included from reg.h - flush_dcache_all() was defined on ppc32 (only), but was never called (although it was exported). Thus this patch removes it from cacheflush.h and from ARCH=powerpc (misc_32.S) entirely. It's left in ARCH=ppc for now, with the prototype moved to ppc_ksyms.c.

This adds code to work around some problems with old versions of Open Firmware, such as on the early powermacs (7500 etc.) and the "Longtrail" CHRP machine. On these machines we have to claim the physical and virtual address ranges explicitly when claiming memory and then set up a V->P mapping. The Longtrail has more problems: setprop doesn't work, and we have to set an "allow-reclaim" variable to 0 in order to get claim on physical memory ranges to fail if the memory is already claimed.

14-eeh-device-bar-save.patch After a PCI device has been resest, the device BAR's and other config space info must be restored to the same state as they were in when the firmware first handed us this device. This will allow the PCI device driver, when restarted, to correctly recognize and set up the device. Tis patch saves the device config space as early as reasonable after the firmware has handed over the device. Te state resore funcion is inteded for use by the EEH recovery routines.

12-eeh-event-dispatcher.patch ppc64: EEH Recovery dispatcher thread This patch adds a mechanism to create recovery threads when an EEH event is received. Since an EEH freeze state may be detected within an interrupt context, we need to get out of the interrupt context before starting recovery. This dispatcher does this in two steps: first, it uses a workqueue to get out, and then lanuches a kernel thread, so that the recovery routine can sleep for exteded periods without upseting the keventd. A kernel thread is created with each EEH event, rather than having one long-running daemon started at boot time. This is because it is anticipated that EEH events will be very rare (very very rare, ideally) and so its pointless to cluter the process tables with a daemon that will almost never run.

09-hotplug-bugfix.patch In the current 2.6.14-rc2-git6 kernel, performing a Dynamic LPAR Add of a hotplug slot will crash the system, with the following (abbreviated) stack trace: cpu 0x3: Vector: 700 (Program Check) at [c000000053dff7f0] pc: c0000000004f5974: .__alloc_bootmem+0x0/0xb0 lr: c0000000000258a0: .update_dn_pci_info+0x108/0x118 c0000000000257c8 .update_dn_pci_info+0x30/0x118 (unreliable) c0000000000258fc .pci_dn_reconfig_notifier+0x4c/0x64 c000000000060754 .notifier_call_chain+0x68/0x9c The root cause was that __init __alloc_bootmem() was called long after boot had finished, resulting in a crash because this routine is undefined after boot time.

07-eeh-report-race.patch When a PCI slot is isolated, all PCI functions under that slot are affected. If hese functions have separate device drivers, the EEH isolation event might be reported multiple times. This patch adds a lock to prevent the racing of such multiple reports.

Having already merged the ppc and ppc64 versions of signal.c, this patch finishes the job by merging signal.h. The two versions were almost identical already. Notable changes: - We use BITS_PER_LONG to correctly size sigset_t - Remove some uneeded #includes and struct forward declarations. This does mean adding an include to signal_32.c which relied on the indirect inclusion of sigcontext.h - As the ppc64 version, the merged signal.h has prototypes for do_signal() and do_signal32(). Thus remove extra prototypes from ppc_ksyms.c which had them directly. Built and booted on POWER5 LPAR (ARCH=ppc64 and ARCH=powerpc).
