* powerpc: Move some extern declarations from C code into headersPaul Mackerras2005-11-09

* [PATCH] powerpc: Move more ppc64 files with no ppc32 equivalent to powerpcDavid Gibson2005-11-09
| | | | | | | | | | | | | | | | | | | | | | | This patch moves a bunch more files from arch/ppc64 and include/asm-ppc64 which have no equivalents in ppc32 code into arch/powerpc and include/asm-powerpc. The file affected are: hvcall.h proc_ppc64.c sysfs.c lparcfg.c rtas_pci.c The only changes apart from the move and corresponding Makefile changes are: - #ifndef/#define in includes updated to _ASM_POWERPC_ form - trailing whitespace removed - comments giving full paths removed Built and booted on POWER5 LPAR (ARCH=powerpc and ARCH=ppc64), built for 32-bit powermac (ARCH=powerpc).

* [PATCH] ppc64: fix PCI IO mappingBenjamin Herrenschmidt2005-11-09
| | | | | | | | | | | | | | | | | phbs_remap_io(), which maps the PCI IO space into the kernel virtual space, is called too early on powermac, and thus doesn't work. This fixes it by removing the call from all platforms and putting it back into the ppc64 common code where it belongs, after the actual probing of the bus. That means that before that call, only the ISA IO space (if any) is mapped, any PIO access (from quirks for example) will fail. This happens not to be a problem for now, but we'll have to rework that code if it becomes one in the future.

* [PATCH] powerpc: merge code values for identifying platformsPaul Mackerras2005-11-09
| | | | | | | | | | | | This patch merges platform codes. systemcfg->platform is no longer used, systemcfg use in general is deprecated as much as possible (and renamed _systemcfg before it gets completely moved elsewhere in a future patch), _machine is now used on ppc64 along as ppc32. Platform codes aren't gone yet but we are getting a step closer. A bunch of asm code in head[_64].S is also turned into C code.

* [PATCH] powerpc: Consolidate asm compatibility macrosDavid Gibson2005-11-09
| | | | | | | | | | | | | | | | | | | | | | | This patch consolidates macros used to generate assembly for compatibility across different CPUs or configs. A new header, asm-powerpc/asm-compat.h contains the main compatibility macros. It uses some preprocessor magic to make the macros suitable both for use in .S files, and in inline asm in .c files. Headers (bitops.h, uaccess.h, atomic.h, bug.h) which had their own such compatibility macros are changed to use asm-compat.h. ppc_asm.h is now for use in .S files *only*, and a #error enforces that. As such, we're a lot more careless about namespace pollution here than in asm-compat.h. While we're at it, this patch adds a call to the PPC405_ERR77 macro in futex.h which should have had it already, but didn't. Built and booted on pSeries, Maple and iSeries (ARCH=powerpc).

* [PATCH] powerpc: Merge cacheflush.h and cache.hDavid Gibson2005-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | * [ARM] Clean up save_and_disable_irqs macro and allow use of ARMv6 CPSIDRussell King2005-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | save_and_disable_irqs does not need to use mov + msr (which was introduced to work around a documentation bug which was propagated into binutils.) Use msr with an immediate constant, and if we're building for ARMv6 or later, use the new CPSID instruction. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
