* | ppc64/powerpc: Fix time initialization on SMP systemsPaul Mackerras2005-10-22
| | | | | | | | | | | | | | | | | | | | | | This moves smp_space_timers from arch/ppc64/kernel/smp.c to arch/powerpc/kernel/time.c and makes it initialize last_jiffy[] instead of paca[].next_jiffy_update_tb, since last_jiffy[] is now what the time code uses. It also declares smp_space_timers in include/asm-powerpc/time.h and gets rid of an ifdef in div128_by_32. Signed-off-by: Paul Mackerras <paulus@samba.org>
* | [PATCH] powerpc: Merge thread_info.hDavid Gibson2005-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge ppc32 and ppc64 versions of thread_info.h. They were pretty similar already, the chief changes are: - Instead of inline asm to implement current_thread_info(), which needs to be different for ppc32 and ppc64, we use C with an asm("r1") register variable. gcc turns it into the same asm as we used to have for both platforms. - We replace ppc32's 'local_flags' with the ppc64 'syscall_noerror' field. The noerror flag was in fact the only thing in the local_flags field anyway, so the ppc64 approach is simpler, and means we only need a load-immediate/store instead of load/mask/store when clearing the flag. - In readiness for 64k pages, when THREAD_SIZE will be less than a page, ppc64 used kmalloc() rather than get_free_pages() to allocate the kernel stack. With this patch we do the same for ppc32, since there's no strong reason not to. - For ppc64, we no longer export THREAD_SHIFT and THREAD_SIZE via asm-offsets, thread_info.h can now be safely included in asm, as on ppc32. Built and booted on G4 Powerbook (ARCH=ppc and ARCH=powerpc) and Power5 (ARCH=ppc64 and ARCH=powerpc).

* | [PATCH] Fix broken initialization of conswitchp for ARCH=ppc64David Gibson2005-10-21
| | | | | | | | | | | | | | | | | | | | In the merge tree, commit 0458060c1c59c5378d8fb5daabe18cf4681c35cd broke boot on some machines because the initialization of conswitchp was moved to arch/powerpc/kernel/setup_64.c, but a corresponding copy was not added to arch/ppc64/kernel/setup.c. This patch fixes it. Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* | powerpc/ppc/ppc64: Various compile fixes.Paul Mackerras2005-10-20
| | | | | | | | | | | | | | | | | | | | This declares powersave_nap in system.h and makes it an int everywhere, fixes typos for the maple platform, fixes a couple of places where I missed removing the last two arguments from a message_pass function, and makes ppc64 consistent with ppc32 in the type of the pci_bridge.cfg_data field.

* | ppc64: Use the merged mpic.cPaul Mackerras2005-10-20

* | powerpc: Move some calculations from xxx_calibrate_decr to time_initPaul Mackerras2005-10-20
| | | | | | | | | | | | | | | | | | | | Previously the individual xxx_calibrate_decr functions would each print the timebase and cpu frequency and calculate several values such as tb_to_us and tb_to_xs. This moves those printks and calculations into time_init just after the call to the platform's calibrate_decr function. Signed-off-by: Paul Mackerras <paulus@samba.org>
* | ppc: rename pci_assign_all_busses to pci_assign_all_busesPaul Mackerras2005-10-20

* | powerpc: Move smp_mpic_message_pass into mpic.cPaul Mackerras2005-10-20

* | [PATCH] powerpc: Merge ppc64 pmc.[ch] with ppc32 perfmon.[ch]David Gibson2005-10-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patches the ppc32 and ppc64 versions of the headers and .c files with helper functions for manipulating the performance counting hardware. As a side effect, it removes use of the term "perfmon" from ppc32, thus avoiding confusion with the unrelated performance counter interface from HP Labs also called "perfmon". Built, but not booted, for g5, pSeries, iSeries, and 32-bit Powermac with both ARCH=powerpc and ARCH=ppc{,64} as appropriate.

* | powerpc: Merge time.c and asm/time.h.Paul Mackerras2005-10-19
| | | | | | | | | | | | | | | | | | | | We now use the merged time.c for both 32-bit and 64-bit compilation with ARCH=powerpc, and for ARCH=ppc64, but not for ARCH=ppc32. This removes setup_default_decr (folds its function into time_init) and moves wakeup_decrementer into time.c. This also makes an asm-powerpc/rtc.h. Signed-off-by: Paul Mackerras <paulus@samba.org>
* | ppc64: Minor compilation fixesPaul Mackerras2005-10-19
| | | | | | | | | | | | | | | | This defines CONFIG_PPC_STD_MMU for ppc64, changes an instance of sys32_ to compat_sys_ in the ppc64 syscall table, and removes a reference to a non-existent arch/powerpc/xmon/Makefile. Signed-off-by: Paul Mackerras <paulus@samba.org>

* | powerpc: Merge machdep.hPaul Mackerras2005-10-19
| | | | | | | | | | | | | | | | | | | | | | | | A few things change for consistency between ppc32 and ppc64: idle functions return void; *_get_boot_time functions return unsigned long (i.e. time_t) rather than filling in a struct rtc_time (since that's useful to the callers and easier for pmac to generate); *_get_rtc_time and *_set_rtc_time functions take a struct rtc_time; irq_canonicalize is gone; nvram_sync returns void.

| | | | | | | | | | | | | | | | | | | | | | | | - added typedef unsigned int __nocast gfp_t; - replaced __nocast uses for gfp flags with gfp_t - it gives exactly the same warnings as far as sparse is concerned, doesn't change generated code (from gcc point of view we replaced unsigned int with typedef) and documents what's going on far better.

| | | | | | | | | | | | | | | | | | | | | | | | BUILD_BUG_ON(1) is asking for trouble (and getting it) when used in that manner - dead code elimination happens after we parse it and invalid type is invalid type, dead code or not.
