2008-02-07vmcoreinfo: fix the configuration dependenciesKen'ichi Ohmichi
This patch fixes the configuration dependencies in the vmcoreinfo data. i386's "node_data" is defined in arch/x86/mm/discontig_32.c, and x86_64's one is defined in arch/x86/mm/numa_64.c. They depend on CONFIG_NUMA: arch/x86/mm/Makefile_32:7 obj-$(CONFIG_NUMA) += discontig_32.o arch/x86/mm/Makefile_64:7 obj-$(CONFIG_NUMA) += numa_64.o ia64's "pgdat_list" is defined in arch/ia64/mm/discontig.c, and it depends on CONFIG_DISCONTIGMEM and CONFIG_SPARSEMEM: arch/ia64/mm/Makefile:9-10 obj-$(CONFIG_DISCONTIGMEM) += discontig.o obj-$(CONFIG_SPARSEMEM) += discontig.o ia64's "node_memblk" is defined in arch/ia64/mm/numa.c, and it depends on CONFIG_NUMA: arch/ia64/mm/Makefile:8 obj-$(CONFIG_NUMA) += numa.o Signed-off-by: Ken'ichi Ohmichi <oomichi@mxs.nes.nec.co.jp> Acked-by: Simon Horman <horms@verge.net.au> Cc: David Rientjes <rientjes@google.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-02-07vmcoreinfo: rename vmcoreinfo's macros returning the sizeKen'ichi Ohmichi
This patchset is for the vmcoreinfo data. The vmcoreinfo data has the minimum debugging information only for dump filtering. makedumpfile (dump filtering command) gets it to distinguish unnecessary pages, and makedumpfile creates a small dumpfile. This patch: VMCOREINFO_SIZE() should be renamed VMCOREINFO_STRUCT_SIZE() since it's always returning the size of the struct with a given name. This change would allow VMCOREINFO_TYPEDEF_SIZE() to simply become VMCOREINFO_SIZE() since it need not be used exclusively for typedefs.

2008-02-07Use BOOTMEM_EXCLUSIVE for kdumpBernhard Walle
Use the BOOTMEM_EXCLUSIVE, introduced in the previous patch, to avoid conflicts while reserving the memory for the kdump capture kernel (crashkernel=).

2008-02-07Introduce flags for reserve_bootmem()Bernhard Walle
This patchset adds a flags variable to reserve_bootmem() and uses the BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions between crashkernel area and already used memory. This patch: Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE. If that flag is set, the function returns with -EBUSY if the memory already has been reserved in the past. This is to avoid conflicts. Because that code runs before SMP initialisation, there's no race condition inside reserve_bootmem_core().

2008-02-07[SPARC64]: Fix booting on non-zero cpu.David S. Miller
The early per-cpu handling needs a slight tweak to work when booting on a non-zero cpu. We got away with this for a long time, but can't any longer as now even printk() calls functions (cpu_clock() for example) that thus make early references to per-cpu variables.

2008-02-07[POWERPC] Add SPE registers to core dumpsRoland McGrath
This makes the SPE register data appear in ELF core dumps, using the new n_type value NT_PPC_SPE (0x101). This new note type is not used by any consumers of core files yet, but support can be added. I don't even have any hardware with SPE capabilities, so I've never seen such a note. But this demonstrates how simple it is to export register information in core dumps when the user_regset style is used for the low-level code.

2008-02-07[POWERPC] Use regset code for compat PTRACE_*REGS* callsRoland McGrath

2008-02-07[POWERPC] Use generic compat_sys_ptraceRoland McGrath

2008-02-07[POWERPC] Use regset code for PTRACE_*REGS* requestsRoland McGrath
This replaces all the code for powerpc PTRACE_*REGS* requests with simple calls to copy_regset_from_user and copy_regset_to_user. All the ptrace formats are either the whole corresponding user_regset format (core dump format) or a leading subset of it, so we can get rid of all the remaining embedded knowledge of both those layouts and of the internal data structures they correspond to. Only the user_regset accessors need to implement that. Signed-off-by: Roland McGrath <roland@redhat.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-02-07[POWERPC] Switch to generic compat_binfmt_elf codeRoland McGrath
This switches the CONFIG_PPC64 support for 32-bit ELF to use the generic fs/compat_binfmt_elf.c implementation instead of our own binfmt_elf32.c. Since so much is the same between 32/64, there is only one macro we have to define to make the generic support work out of the box.

2008-02-07[POWERPC] Add user_regset compat supportRoland McGrath
This extends task_user_regset_view CONFIG_PPC64 with support for the 32-bit view of register state, compatible with what a CONFIG_PPC32 kernel provides. This will enable generic machine-independent code to access user-mode threads' registers for debugging and dumping.

2008-02-07[POWERPC] Add user_regset_view definitionsRoland McGrath

2008-02-07[POWERPC] Use user_regset accessors for GPRsRoland McGrath

2008-02-07[POWERPC] ptrace accessors for special regs MSR and TRAPRoland McGrath
This isolates the ptrace code for the special-case registers msr and trap from the ptrace-layout dispatch code. This should inline away completely.
