* [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: Fix some bugs in the new merged time codePaul Mackerras2005-10-20
| | | | | | | | | | I had the sense of the test for when to use the old 601-style RTC registers inverted. pmac_calibrate_decr and via_calibrate_decr weren't setting ppc_tb_freq, on which all the further calculations depended. Lastly, update_gtod was losing the top 32 bits of the new tb_to_xs value. 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. Signed-off-by: Paul Mackerras <paulus@samba.org>
* ppc64: Use the merged mpic.cPaul Mackerras2005-10-20
| | | | | | This means we now compile in arch/powerpc/sysdev for ARCH=ppc64. Signed-off-by: Paul Mackerras <paulus@samba.org>
* 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>
* ppc64: Move init_boot_text call and conswitchp init into setup_archPaul Mackerras2005-10-20
| | | | | | | This way they get done in one place for all platforms, and it is more consistent with what ppc32 does. Signed-off-by: Paul Mackerras <paulus@samba.org>
* ppc: rename pci_assign_all_busses to pci_assign_all_busesPaul Mackerras2005-10-20

* powerpc: Merge various powermac-related header files.Paul Mackerras2005-10-20
| | | | | | | | | Except for smu.h, which moved from asm-ppc64 to asm-powerpc, all of these moved from asm-ppc to asm-powerpc. In each case the asm-ppc64 version (if there was one) was just a single line including the asm-ppc version. Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Fix places where ppc_md.show_[per]cpuinfo was treated as intPaul Mackerras2005-10-20
| | | | | | | I missed a few places where ppc code was still assuming that the ppc_md.show_[per]cpuinfo functions returned int. Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Move smp_mpic_message_pass into mpic.cPaul Mackerras2005-10-20
| | | | | | | Having it here rather than in arch/ppc64/kernel/smp.c means that we can use it on 32-bit SMP systems easily with ARCH=powerpc. Signed-off-by: Paul Mackerras <paulus@samba.org>
* ppc64: Change ppc_md.get_cpuinfo to ppc_md.show_cpuinfoPaul Mackerras2005-10-20

* [PATCH] powerpc: Merge types.hBecky Bruce2005-10-20
| | | | | | | | | | | | | This patch merges types.h into include/asm-powerpc. The only real change is the removal of the include of linux/config.h from the 32-bit version - it doesn't appear to be necessary. This patch has been built on several different 32 and 64-bit platforms, and booted on mpc8540_ads.

* [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.

* ppc: Minor smp changes for consistency with ppc64Paul Mackerras2005-10-19
| | | | | | | | | This makes platform code use the smp_ops variable directly instead of ppc_md.smp_ops, removes the two unused `data' and `wait' arguments from the *_message_pass() functions, and removes the call to the never-implemented smp_ops->space_timers() function.

* powerpc: Initialize btext subsystem later, after prom_initPaul Mackerras2005-10-17
| | | | | | | | | | | | We were initializing the btext stuff from prom_init(), thus breaking the rule that all communication between prom_init() and the rest of the kernel has to be via the flattened device tree. This removes the btext initialization calls from prom_init() and initializes it instead after the device tree is unflattened. It would be nice to do it earlier, but that needs some more infrastructure to find the properties we need in the flattened device tree. Signed-off-by: Paul Mackerras <paulus@samba.org>
