* 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: Move ptrace32.c from arch/ppc64 to arch/powerpcPaul Mackerras2005-10-19

* 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. Signed-off-by: Paul Mackerras <paulus@samba.org>
* 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: change sys32_ to compat_sys_Stephen Rothwell2005-10-18
| | | | | | | | | | | | | | | | | | This allows us to get rid of one type of entry in systbl.S. In passing we remove the duplicate compat_sys_getdents and compat_sys_utimes for which there are generic versions. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
* | powerpc: Fix various compile errors with ARCH=ppc, ppc64 and powerpcPaul Mackerras2005-10-18
|/ | | | | | | | This makes ppc use the syscalls.c from arch/powerpc/kernel, exports copy_and_flush from head_32.S for use by prom_init.c (ARCH=powerpc), and consolidates the sys_fadvise64_64 implementations for 32-bit. Signed-off-by: Paul Mackerras <paulus@samba.org>

* [PATCH] powerpc: Fix use of LOADBASE in merge treeDavid Gibson2005-10-17
| | | | | | | | | | The merge-tree version of LOADBASE actually loads the whole given address from the toc for ppc64. The matching OFF macro adjust for this, using an offset of 0 for ppc64, but we weren't using that in power4_idle.

* 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>

| | * [SPARC64]: Fix net booting on Ultra5David S. Miller2005-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were not doing alignment properly when remapping the kernel image. What we want is a 4MB aligned physical address to map at KERNBASE. Mistakedly we were 4MB aligning the virtual address where the kernel initially sits, that's wrong. Instead, we should PAGE align the virtual address, then 4MB align the physical address result the prom gives to us. Signed-off-by: David S. Miller <davem@davemloft.net>
| | * [SPARC32]: Revert IOMAP change eb98129eec7fa605f0407dfd92d40ee8ddf5cd9aDavid S. Miller2005-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Breakage noted by Al Viro. It breaks non-PCI builds, it's probably better to have a more direct implementation on sparc32, and which driver actually needs this is still questionable.

| * | [PATCH] ppc highmem fixPaolo Galtieri2005-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've noticed that the calculations for seg_size and nr_segs in __dma_sync_page_highmem() (arch/ppc/kernel/dma-mapping.c) are wrong. The incorrect calculations can result in either an oops or a panic when running fsck depending on the size of the partition. The problem with the seg_size calculation is that it can result in a negative number if size is offset > size. The problem with the nr_segs caculation is returns the wrong number of segments, e.g. it returns 1 when size is 200 and offset is 4095, when it should return 2 or more.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the boot processor, we need to do the move onto the Linux trap table a little bit differently else we'll take unhandlable faults in the firmware address space. Previously we would do the following: 1) Disable PSTATE_IE in %pstate. 2) Set %tba by hand to sparc64_ttable_tl0 3) Initialize alternate, mmu, and interrupt global trap registers. 4) Call prom_set_traptable() That doesn't work very well actually with the way we boot the kernel VM these days. It worked by luck on many systems because the firmware accesses for the prom_set_traptable() call happened to be loaded into the TLB already, something we cannot assume. So the new scheme is this: 1) Clear PSTATE_IE in %pstate and set %pil to 15 2) Call prom_set_traptable() 3) Initialize alternate, mmu, and interrupt global trap registers. and this works quite well. This sequence has been moved into a callable function in assembler named setup-trap_table(). The idea is that eventually trampoline.S can use this code as well. That isn't possible currently due to some complications, but eventually we should be able to do it. Thanks to Meelis Roos for the Ultra5 boot failure report. Signed-off-by: David S.
