2008-01-30x86: compat_binfmt_elf KconfigRoland McGrath2-0/+5
This adds Kconfig and Makefile bits to build fs/compat_binfmt_elf.c, just added. Each arch that wants to use this file needs to add a "select COMPAT_BINFMT_ELF" line in its Kconfig bits that enable COMPAT.

2008-01-30x86: compat_binfmt_elfRoland McGrath1-0/+131
This adds fs/compat_binfmt_elf.c, a wrapper around fs/binfmt_elf.c for 32-bit ELF support on 64-bit kernels. It can replace all the hand-rolled versions of this that each 32/64 arch has, which are all about the same. To use this, an arch's asm/elf.h has to define at least a few compat_* macros that parallel the various macros that fs/binfmt_elf.c uses for native support. There is no attempt to deal with compat macros for the core dump format support. To use this file, the arch has to define compat_gregset_t for linux/elfcore-compat.h and #define CORE_DUMP_USE_REGSET. The 32-bit compatible formats should come automatically from task_user_regset_view called on a 32-bit task.

2008-01-30x86: user_regset helpersRoland McGrath1-0/+116
This adds some inlines to linux/regset.h intended for arch code to use in its user_regset get and set functions. These make it pretty easy to deal with the interface's optional kernel-space or user-space pointers and its generalized access to a part of the register data at a time. In simple cases where the internal data structure matches the exported layout (core dump format), a get function can be nothing but a call to user_regset_copyout, and a set function a call to user_regset_copyin. In other cases the exported layout is usually made up of a few pieces each stored contiguously in a different internal data structure. These helpers make it straightforward to write a get or set function by processing each contiguous chunk of the data in order. The start_pos and end_pos arguments are always constants, so these inlines collapse to a small amount of code.

2008-01-30elf core dump: notes user_regsetRoland McGrath1-0/+224
This modifies the ELF core dump code under #ifdef CORE_DUMP_USE_REGSET. It changes nothing when this macro is not defined. When it's #define'd by some arch header (e.g. asm/elf.h), the arch must support the user_regset (linux/regset.h) interface for reading thread state. This provides an alternate version of note segment writing that is based purely on the user_regset interfaces. When CORE_DUMP_USE_REGSET is set, the arch need not define macros such as ELF_CORE_COPY_REGS and ELF_ARCH. All that information is taken from the user_regset data structures. The core dumps come out exactly the same if arch's definitions for its user_regset details are correct.

2008-01-30elf core dump: notes reorgRoland McGrath1-130/+194
This pulls out the code for writing the notes segment of an ELF core dump into separate functions. This cleanly isolates into one cluster of functions everything that deals with the note formats and the hooks into arch code to fill them. The top-level elf_core_dump function itself now deals purely with the generic ELF format and the memory segments. This only moves code around into functions that can be inlined away. It should not change any behavior at all. Signed-off-by: Roland McGrath <roland@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-01-30x86: user_regset headerRoland McGrath1-0/+206
The new header <linux/regset.h> defines the types struct user_regset and struct user_regset_view, with some associated declarations. This new set of interfaces will become the standard way for arch code to expose user-mode machine-specific state. A single set of entry points into arch code can do all the low-level work in one place to fill the needs of core dumps, ptrace, and any other user-mode debugging facilities that might come along in the future. For existing arch code to adapt to the user_regset interfaces, each arch can work from the code it already has to support core files and ptrace. The formats you want for user_regset are the core file formats. The only wrinkle in adapting old ptrace implementation code as user_regset get and set functions is that these functions can be called on current as well as on another task_struct that is stopped and switched out as for ptrace. For some kinds of machine state, you may have to load it directly from CPU registers or otherwise differently for current than for another thread. (Your core dump support already handles this in elf_core_copy_regs for current and elf_core_copy_task_regs for other tasks, so just check there.) The set function should also be made to work on current in case that entails some special cases, though this was never required before for ptrace. Adding this flexibility covers the arch needs to open the door to more sophisticated new debugging facilities that don't always need to context-switch to do every little thing. The copyin/copyout helper functions (in a later patch) relieve the arch code of most of the cumbersome details of the flexible get/set interfaces.

2008-01-30x86, kexec: force x86 arches to boot kdump kernels on boot cpuNeil Horman1-21/+65
Recently a kdump bug was discovered in which a system would hang inside calibrate_delay during the booting of the kdump kernel. This was caused by the fact that the jiffies counter was not being incremented during timer calibration. The root cause of this problem was found to be a bios misconfiguration of the hypertransport bus. On system affected by this hang, the bios had assigned APIC ids which used extended apic bits (more than the nominal 4 bit ids's), but failed to configure bit 17 of the hypertransport transaction config register, which indicated that the mask for the destination field of interrupt packets accross the ht bus (see section 3.3.9 of http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/26094.PDF). If a crash occurs on a cpu with an APIC id that extends beyond 4 bits, it will not recieve interrupts during the kdump kernel boot, and this hang will be the result. The fix is to add this patch, whcih add an early pci quirk check, to forcibly enable this bit in the httcfg register. This enables all cpus on a system to receive interrupts, and allows kdump kernel bootup to procede normally.
