2017-03-02sched/headers: Prepare to remove the <linux/mm_types.h> dependency from ↵Ingo Molnar
<linux/sched.h> Update code that relied on sched.h including various MM types for them. This will allow us to remove the <linux/mm_types.h> include from <linux/sched.h>.

2009-11-10hw-breakpoints: Fix broken a.out format dumpFrederic Weisbecker
Fix the broken a.out format dump. For now we only dump the ptrace breakpoints. TODO: Dump every perf breakpoints for the current thread, not only ptrace based ones.

2009-06-02hw-breakpoints: prepare the code for Hardware Breakpoint interfacesK.Prasad
The generic hardware breakpoint interface provides an abstraction of hardware breakpoints in front of specific arch implementations for both kernel and user side breakpoints. This includes execution breakpoints and read/write breakpoints, also known as "watchpoints". This patch introduces header files containing constants, structure definitions and declaration of functions used by the hardware breakpoint core and x86 specific code. It also introduces an array based storage for the debug-register values in 'struct thread_struct', while modifying all users of debugreg<n> member in the structure. [ Impact: add headers for new hardware breakpoint interface ] Original-patch-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: K.Prasad <prasad@linux.vnet.ibm.com> Reviewed-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com>
2009-02-10x86: add %gs accessors for x86_32Tejun Heo
Impact: cleanup On x86_32, %gs is handled lazily. It's not saved and restored on kernel entry/exit but only when necessary which usually is during task switch but there are few other places. Currently, it's done by calling savesegment() and loadsegment() explicitly. Define get_user_gs(), set_user_gs() and task_user_gs() and use them instead. While at it, clean up register access macros in signal.c. This cleans up code a bit and will help future changes. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-09x86: include correct %gs in a.out core dumpTejun Heo
Impact: dump the correct %gs into a.out core dump aout_dump_thread() read %gs but didn't include it in core dump. Fix it. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-10-22x86: Fix ASM_X86__ header guardsH. Peter Anvin
Change header guards named "ASM_X86__*" to "_ASM_X86_*" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
