| * | [PATCH] powerpc: Keep fixing merged ipcbuf.hDavid Gibson2005-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Oops, replacing the two u64s in struct ipc64_perm with __u32s changed the alignment of that structure, which could mess up userspace. Revert to using two unsigned long longs (which is what ppc32 had originally). ppc64 orignally had two unsigned longs, but long long is the same size on 64 bit, so this should be ok there too.

| | | | | | | | | | | | | | | | | | This moves rtas-proc.c and rtas_flash.c into arch/powerpc/kernel, since cell wants them as well as pseries (and chrp can use rtas-proc.c too, at least in principle). rtas_fw.c is gone, with its bits moved into rtas_flash.c and rtas.c.

* | powerpc: Fix random memory corruption in merged elf.hMichael Ellerman2005-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The merged verison of ELF_CORE_COPY_REGS is basically the PPC64 version, with a memset that came from PPC and a few types abstracted out into #defines. But it's not _quite_ right. The first problem is we calculate the number of registers with: nregs = sizeof(struct pt_regs) / sizeof(ELF_GREG_TYPE) For a 32-bit process on a 64-bit kernel that's bogus because the registers are 64 bits, but ELF_GREG_TYPE is u32, so nregs == 88 which is wrong. The other problem is the memset, which assumes a struct pt_regs is smaller than a struct elf_regs. For a 32-bit process on a 64-bit kernel that's false. The fix is to calculate the number of regs using sizeof(unsigned long), which should always be right, and just memset the whole damn thing _before_ copying the registers in.

* | powerpc: Implement smp_release_cpus() in C not asmMichael Ellerman2005-11-03
| | | | | | | | | | | | | | | | | | | | There's no reason for smp_release_cpus() to be asm, and most people can make more sense of C code. Add an extern declaration to smp.h and remove the custom one in machine_kexec.c Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
* | powerpc: Cleanup vpa codeMichael Ellerman2005-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | register_vpa() doesn't actually do a VPA register call it just uses the flags you pass it, so rename it to vpa_call() to be clearer. We can then define register_vpa() and unregister_vpa() which are both simple wrappers around vpa_call(). (we'll need unregister_vpa() for kexec soon) We can then cleanup vpa_init(), and because vpa_init() is only called from platforms/pseries we remove the definition in asm-ppc64/smp.h.

* | powerpc: Add helper functions for synthesising instructions at runtimeMichael Ellerman2005-11-03
| | | | | | | | | | | | | | | | There's a few places already, and soon will be more, where we synthesise branch instructions at runtime. Rather than doing it by hand in each case, it would make sense to have one implementation. Signed-off-by: Michael Ellerman <michael@ellerman.id.au>
* | powerpc: Merge asm-ppc/kexec.h and asm-ppc64/kexec.hMichael Ellerman2005-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | Merge include/asm-ppc/kexec.h and include/asm-ppc64/kexec.h. The only thing that's really changed is that we now allocate crash_notes properly on PPC32. It's address is exported via sysfs, so it's not correct for it to be a pointer. I've also removed some of the "we don't use this" comments, because they're wrong (or perhaps were referring only to arch code). Signed-off-by: Michael Ellerman <michael@ellerman.id.au>

| * [PATCH] powerpc: Move naca.h to platforms/iseriesDavid Gibson2005-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | These days, the NACA only exists on iSeries. Therefore, this patch moves naca.h from include/asm-ppc64 to arch/powerpc/platforms/iseries. There was one file including naca.h outside of platforms/iseries - arch/ppc64/kernel/udbg_scc.c. However, that's obviously a hangover from older days. The include is not necessary, so this patch simply removes it. Built and booted on iSeries, built for G5 (which uses udbg_scc.o).

| * [PATCH] powerpc: Move dart.hDavid Gibson2005-11-01
| | | | | | | | | | | | | | | | | | | | | | | | | | asm-ppc64/dart.h is included in exactly one place - arch/powerpc/sysdev/u3_iommu.c. This patch, therefore, moves it into arch/powerpc/sysdev. While we're at it, update the #ifndef/#define protecting the include, and the filename in the comments of u3_iommu.c. Built and booted on pSeries and G5, built for ppc32 powermac.

| * [PATCH] powerpc: Merge (move) numnodes.h and sparsemem.hDavid Gibson2005-11-01
| | | | | | | | | | | | | | | | | | | | | | | | | | The ppc64 versions of numnodes.h and sparsemem.h can be safely moved to asm-powerpc with no changes apart from changing the #define to the standard _ASM_POWERPC_ form. There are no ppc32 versions of these files, because they only have any effect if CONFIG_SPARSEMEM is enabled, which it never can be on ppc32. Built and booted on pSeries (POWER5), built for 32-bit powermac. Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

| | * [PATCH] Creative Audigy 2 cardbus: Add IO window wakeup magicJames Courtier-Dutton2005-10-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the magic IO wakeup code for the CardBus version of the Creative Labs Audigy 2 to the snd-emu10k1 driver. Without the magic IO enable sequence, reading from the IO region of the card will fail spectacularly, and the machine will hang. My next task will be getting the driver to actually play sound without distortion. Signed-off-by: James Courtier-Dutton <James@superbug.co.uk> [ This is a work-in-progress, but since it avoids a total lockup if the emu10k module is loaded on a machine with the cardbus card inserted, we're better off with it than without it, even if sound quality is bad right now ] Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch merges the ppc32 and ppc64 versions of futex.h, essentially by taking the ppc64 version as the powerpc version. The old ppc32 version did not implement the futex_atomic_op_inuser() callback (it always returned -ENOSYS), so FUTEX_WAKE_OP would not work on ppc32. In fact the ppc64 version of this function is almost suitable for ppc32 as well - the only change needed is to extend ppc_asm.h with a macro expanding to to the right pseudo-op to store a pointer (either ".long" or ".llong"). Built and booted on pSeries. Built for 32-bit powermac. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
