* sched/headers: Prepare for new header dependencies before moving code to ↵Ingo Molnar2017-03-021-0/+1
| | | | | | | | | | | | | | | | | | | | <linux/sched/task_stack.h> We are going to split <linux/sched/task_stack.h> out of <linux/sched.h>, which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder <linux/sched/task_stack.h> file that just maps to <linux/sched.h> to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

* ARCH: AUDIT: audit_syscall_entry() should not require the archEric Paris2014-09-231-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | We have a function where the arch can be queried, syscall_get_arch(). So rather than have every single piece of arch specific code use and/or duplicate syscall_get_arch(), just have the audit code use the syscall_get_arch() code.

* audit: define AUDIT_ARCH_OPENRISCKees Cook2012-09-211-1/+1
| | | | | | | | | | | | | | When using audit on OpenRISC, an audit arch is needed. This defines it and fixes a compile-time bug uncovered in linux-next, likely from a cut/paste from an arch with 64/32-bit modes that defined arch_arch(): arch/openrisc/kernel/ptrace.c:190:2: error: implicit declaration of function 'audit_arch' This replaces it with the newly defined AUDIT_ARCH_OPENRISC, since it is only 32-bit, and currently only operates in big-endian mode.

I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that. We'll find out anything that got broken and fix it.. * tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system: (38 commits) Delete all instances of asm/system.h Remove all #inclusions of asm/system.h Add #includes needed to permit the removal of asm/system.h Move all declarations of free_initmem() to linux/mm.h Disintegrate asm/system.h for OpenRISC Split arch_align_stack() out from asm-generic/system.h Split the switch_to() wrapper out of asm-generic/system.h Move the asm-generic/system.h xchg() implementation to asm-generic/cmpxchg.h Create asm-generic/barrier.h Make asm-generic/cmpxchg.h #include asm-generic/cmpxchg-local.h Disintegrate asm/system.h for Xtensa Disintegrate asm/system.h for Unicore32 [based on ver #3, changed by gxt] Disintegrate asm/system.h for Tile Disintegrate asm/system.h for Sparc Disintegrate asm/system.h for SH Disintegrate asm/system.h for Score Disintegrate asm/system.h for S390 Disintegrate asm/system.h for PowerPC Disintegrate asm/system.h for PA-RISC Disintegrate asm/system.h for MN10300 ...

* | openrisc: sanitize use of orig_gpr11Jonas Bonn2012-03-061-2/+2
|/ | | | | | | | | | The pt_regs struct had both a 'syscallno' field and an 'orig_gpr11' field and it wasn't really clear how these were supposed to be used. This patch removes the syscallno field altogether and makes orig_gpr11 work more like other architectures: keep track of syscall number in progress or hold -1 for non-syscall exceptions.

* openrisc: Fix up audit_syscall_[entry|exit]() usageJonas Bonn2012-02-171-8/+4
| | | | | | | | | | | Commits d7e7528bcd456f5c36ad4a202ccfb43c5aa98bc4 and b05d8447e7821695bc2fa3359431f7a664232743 simplified the usage of the audit_syscall_[entry|exit] functions. Unfortunately, the OpenRISC architecture didn't get fixed up along with the other architectures when those patches were pushed. This makes the relevant changes to this architecture.

* OpenRISC: PTraceJonas Bonn2011-07-221-0/+211
This patch implements minimal PTrace support. The pt_regs structure is not exported to userspace for OpenRISC; rather, the GETREGSET mechanism is intended to be used and the registers, as such, exported in the core dump format which is ABI stable. This is in line with what is intended for new architectures as of 2.6.34 and has the advantage of permitting the layout of the registers on the kernel stack (as per pt_regs) to be freely modified.
