19-rpaphp-crashing.patch This patch fixes a bug related to dlpar PHB add, after a PHB removal. -- The crash was due to the PHB not having a pci_dn structure yet, when the phb is being added. This code survived testing, of adding and removeig the PHB and all slots underneath it, 17 times so far, as of this writing.

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).

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.

If the call to xprt_transmit() fails due to socket buffer space exhaustion, we do not need to re-encode the RPC message when we loop back through call_transmit. Re-encoding can actually end up triggering the WARN_ON() in call_decode() if we re-encode something like a read() request and auth->au_rslack has changed. It can also cause us to increment the RPCSEC_GSS sequence number beyond the limits of the allowed window.

We were getting the last_jiffy per-cpu variable set ahead of the current timebase in smp_space_timers on SMP machines. This caused the loop in timer_interrupt to loop virtually forever, since tb_ticks_since assumes that it will never be called with the timebase behind the last_jiffy value.

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.

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). Built for 32-bit powermac (ARCH=powerpc) and Walnut (ARCH=ppc). Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

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. Built for Walnut (ARCH=ppc), 32-bit multiplatform (pmac, CHRP and PReP ARCH=ppc, pmac and CHRP ARCH=powerpc). Built and booted on POWER5 LPAR (ARCH=powerpc and ARCH=ppc64).

The generic netlink family builds on top of netlink and provides simplifies access for the less demanding netlink users. It solves the problem of protocol numbers running out by introducing a so called controller taking care of id management and name resolving. Generic netlink modules register themself after filling out their id card (struct genl_family), after successful registration the modules are able to register callbacks to command numbers by filling out a struct genl_ops and calling genl_register_op(). The registered callbacks are invoked with attributes parsed making life of simple modules a lot easier. Although generic netlink modules can request static identifiers, it is recommended to use GENL_ID_GENERATE and to let the controller assign a unique identifier to the module. Userspace applications will then ask the controller and lookup the idenfier by the module name. Due to the current multicast implementation of netlink, the number of generic netlink modules is restricted to 1024 to avoid wasting memory for the per socket multiacst subscription bitmask.

Introduces netlink_run_queue() to handle the receive queue of a netlink socket in a generic way. Processes as much as there was in the queue upon entry and invokes a callback function for each netlink message found. The callback function may refuse a message by returning a negative error code but setting the error pointer to 0 in which case netlink_run_queue() will return with a qlen != 0.

Introduces a new type-safe interface for netlink message and attributes handling. The interface is fully binary compatible with the old interface towards userspace. Besides type safety, this interface features attribute validation capabilities, simplified message contstruction, and documentation.
