um: clean arch_ptrace() up a bit

2011-09-15T01:09:37+00:00

1) take subarch-specific stuff to subarch_ptrace()
2) PTRACE_{PEEK,POKE}{TEXT,DATA} is handled by ptrace_request() just fine...

[ poleg@redhat.com: no need to declare show_regs() in ptrace.h, sched.h does this ]

um: clean up delay functions

2011-07-26T03:57:12+00:00

Both sys-i386 and sys-x86_64 support now ndelay().  The delay functions
are based on arch/x86/lib/delay.c.

um: add asm/percpu.h

2011-06-28T01:00:12+00:00

To make SLUB work on UML we need this_cpu_cmpxchg from
asm-generic/percpu.h.

Remove unused PROC_CHANGE_PENALTY constant

2011-05-25T15:39:43+00:00

This constant hasn't been used since before the git era (2.6.12) and thus
can be dropped.

Merge branch 'for-2.6.40' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu

2011-05-24T18:53:42+00:00

* 'for-2.6.40' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu:
  percpu: Unify input section names
  percpu: Avoid extra NOP in percpu_cmpxchg16b_double
  percpu: Cast away printk format warning
  percpu: Always align percpu output section to PAGE_SIZE

Fix up fairly trivial conflict in arch/x86/include/asm/percpu.h as per Tejun

um: adjust current_thread_info() for newer gcc versions

2011-04-28T18:28:21+00:00

In some cases gcc >= 4.5.2 will optimize away current_thread_info().  To
prevent gcc from doing so the stack address has to be obtained via inline
asm.

um: fix call tracer and bug handler

2011-04-14T23:06:56+00:00

Commit 1de1502c ("x86, um: now we can get rid of trivial uml headers")
removed accidentally bug.h which broke UML's call tracer and bug
handler.

Without asm-generic/bug.h UML uses BUG() from arch/x86/ which makes use
of ud2.  UML cannot use ud2, it raises SIGILL in user mode.  As UML has
a different stack for handling signals the call trace will be cut off.
