* microblaze: use generic ptrace_resume codeChristoph Hellwig2010-03-121-37/+0
| | | | | | | | | | | | | | | | | | | Use the generic ptrace_resume code for PTRACE_SYSCALL, PTRACE_CONT and PTRACE_KILL. This also makes PTRACE_SINGLESTEP return -EIO while it previously succeeded despite not actually causing any kind of single stepping. Also the TIF_SYSCALL_TRACE thread flag is now cleared on PTRACE_KILL which it previously wasn't which is consistent with all architectures using the modern ptrace code.

* ptrace: use ptrace_request() in the remaining architecturesChristoph Hellwig2010-03-121-26/+1
| | | | | | | | | | | | | | | | | | | | | Use ptrace_request() in the three remaining architectures that didn't use it (m68knommu, h8300, microblaze). This means: - ptrace_request now handles PTRACE_{PEEK,POKE}{TEXT,DATA} and PTRACE_DETATCH calls that were previously called directly, or in case of h8300 even open coded. - adds new support for PTRACE_SETOPTIONS/PTRACE_GETEVENTMSG/ PTRACE_GETSIGINFO/PTRACE_SETSIGINFO Signed-off-by: Christoph Hellwig <hch@lst.de> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: Yoshinori Sato <ysato@users.sourceforge.jp> Cc: Oleg Nesterov <oleg@redhat.com> Cc: Michal Simek <monstr@monstr.eu> Acked-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Roland McGrath <roland@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| * | | | MM: Pass a PTE pointer to update_mmu_cache() rather than the PTE itselfRussell King2010-02-201-1/+1

We do this via make_coherent() by making the pages uncacheable. This used to work fine, until we allowed highmem with highpte - we now have a page table which is mapped as required, and is not available for modification via update_mmu_cache(). Ralf Beache suggested getting rid of the PTE value passed to update_mmu_cache(): On MIPS update_mmu_cache() calls __update_tlb() which walks pagetables to construct a pointer to the pte again. Passing a pte_t * is much more elegant. Maybe we might even replace the pte argument with the pte_t? Ben Herrenschmidt would also like the pte pointer for PowerPC: Passing the ptep in there is exactly what I want. I want that -instead- of the PTE value, because I have issue on some ppc cases, for I$/D$ coherency, where set_pte_at() may decide to mask out the _PAGE_EXEC. So, pass in the mapped page table pointer into update_mmu_cache(), and remove the PTE value, updating all implementations and call sites to suit.

There is no good reason for the difference, it is just an artifact of the code diverging over a couple of years. This patch renames both to simply .phandle. Note: the .node also existed in PowerPC/MicroBlaze, but the only user seems to be arch/powerpc/platforms/powermac/pfunc_core.c. It doesn't look like the assignment between .linux_phandle and .node is significantly different enough to warrant the separate code paths unless ibm,phandle properties actually appear in Apple device trees. I think it is safe to eliminate the old .node property and use phandle everywhere. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The simplest method was to add an extra asm-offsets.h file in arch/$ARCH/include/asm that references the generated file. We can now migrate the architectures one-by-one to reference the generated file direct - and when done we can delete the temporary arch/$ARCH/include/asm/asm-offsets.h file.

The microblaze omission seems like an error to me, so let's kill this ifdef and make sure we are the same everywhere.
