Ananth N Mavinakayanahalli 991a51d83a [PATCH] Kprobes: Use RCU for (un)register synchronization - arch changes
Changes to the arch kprobes infrastructure to take advantage of the locking
changes introduced by usage of RCU for synchronization.  All handlers are now
run without any locks held, so they have to be re-entrant or provide their own

Ananth N Mavinakayanahalli 66ff2d0691 [PATCH] Kprobes: rearrange preempt_disable/enable() calls
The following set of patches are aimed at improving kprobes scalability.  We
currently serialize kprobe registration, unregistration and handler execution
using a single spinlock - kprobe_lock.

With these changes, kprobe handlers can run without any locks held.  It also
allows for simultaneous kprobe handler executions on different processors as
we now track kprobe execution on a per processor basis.  It is now necessary
that the handlers be re-entrant since handlers can run concurrently on
multiple processors.

All changes have been tested on i386, ia64, ppc64 and x86_64, while sparc64
has been compile tested only.

The patches can be viewed as 3 logical chunks:

patch 1: 	Reorder preempt_(dis/en)able calls
patches 2-7: 	Introduce per_cpu data areas to track kprobe execution
patches 8-9: 	Use RCU to synchronize kprobe (un)registration and handler
		execution.

Thanks to Maneesh Soni, James Keniston and Anil Keshavamurthy for their
review and suggestions. Thanks again to Anil, Hien Nguyen and Kevin Stafford
for testing the patches.

This patch:

Reorder preempt_disable/enable() calls in arch kprobes files in preparation to
introduce locking changes.  No functional changes introduced by this patch.

Christoph Hellwig 481bed4542 [PATCH] consolidate sys_ptrace()
The sys_ptrace boilerplate code (everything outside the big switch
statement for the arch-specific requests) is shared by most architectures.
This patch moves it to kernel/ptrace.c and leaves the arch-specific code as
arch_ptrace.

Some architectures have a too different ptrace so we have to exclude them.
They continue to keep their implementations.  For sh64 I had to add a
sh64_ptrace wrapper because it does some initialization on the first call.
For um I removed an ifdefed SUBARCH_PTRACE_SPECIAL block, but
SUBARCH_PTRACE_SPECIAL isn't defined anywhere in the tree.

Martin Schwidefsky d4b6899678 [PATCH] s390: remove pagex support
Remove pagex pseudo page fault code.  It does not work together with the
system call speedup that makes the complete system call path enabled for
interrupts.  To make pagex and the syscall speedup code work together we would
have to add code to the program check handler to do a critical section cleanup
like the asynchronous interrupt code.  This would make program checks slower.
Not what we want.

Newer versions of z/VM have the improved pfault pseudo page fault interface.
This replaces the old pagex interface and does not have the problem.  So its
better to just rip out the pagex code.

Paolo 'Blaisorblade' Giarrusso 26d89d1eef [PATCH] uml: build host-binaries with the native host arch again
This patch reverts back the changes to HOSTCFLAGS and HOSTLDFLAGS

When we were building complete binaries to get constants (such as ptrace
register layout on stack) from host userspace headers, we needed to make the
arch for building HOST binaries match our one: i.e.  on a 64bit system
compiling 32bit binaries, we compile 32-bit hostprogs and need, say, 32-bit
ncurses.  Now we can revert that - that avoids problem with, say, menuconfig
and ncurses, on a system which can't compile well 32-bit programs.

By chance I spotted a bug in zones_setup involving a change to ZONE_*

So, possibly, instead of zones_size[2] you will find zones_size[3] in the

 * UML disables the default_ldt, inherited from the host (SKAS3)
   or resets LDT entries, set by host's clib and inherited in
   SKAS0
 * A new global variable skas_needs_stub is inserted, that
   can be used to decide, whether stub-pages must be supported
   or not.
 * Uses the syscall-stub to replace missing PTRACE_LDT (therefore,
   write_ldt_entry needs to be modified)

Paolo 'Blaisorblade' Giarrusso 4f0272415a [PATCH] uml: fix syscall stubs
Jeff Dike noted that the assembly code for syscall stubs is misassembled with
GCC 3.2.3: the values copied in registers weren't preserved between one asm()
and the following one.

So I fixed the thing by rewriting the __asm__ constraints more like unistd.h
ones.

Note: in syscall6 case I had to add one more instruction (i.e.  moving arg6 in
eax and shuffling things around) - it's needed for the function to be valid in
general (we can't load the value from the stack, relative to ebp, because we
change it), but could be avoided since we actually use a constant as param 6.

The only fix would be to turn stub_syscall6 to a macro and use a "i"
constraint for arg6 (i.e., specify it's a constant value).

Zwane Mwaikambo 77f72b192f [PATCH] i386: LVT entries remaining unmasked on reboot
Excerpt from bugzilla entry

http://bugzilla.kernel.org/show_bug.cgi?id=5518

"i386 version of Reboot-through-BIOS is unsafe: it forgets to mask APIC LVT
interrupts before jumping to a BIOS entry point.  As a result, BIOS ends up
bombarded with interrupts early on boot.  The BIOS does not expect it since
following a "normal" hardware cpu reset, all APIC LVT registers have the
Mask bit (16) set and can't generate interrupts.

For example, the version of Phoenix BIOS used by VMware enables interrupts
for the first time before masking/clearing APIC LVT.  The APIC Timer LVT
register is still set up for a timer interrupt delivery with a high vector
from the previous Linux incarnation (0xef in our case).  The BIOS has not
fully initialized its IDT at this point and the real mode gate for 0xef
remains all zeros.  Vector 0xef dispatches BIOS to address 0:0, BIOS takes
a #GP and eventually hangs.

machine_shutdown() does attempt to shut down APIC before jumping to BIOS,
but it is ineffective"

(the last bits were in the discontig code, which should now also be gone --
this also fixes up a build error in the non-discontig case).

pfn_valid() gives the desired behaviour, so we switch to that.

Paul Mundt 65463b73b1 [PATCH] sh: Drop hp690 discontig support
There was only one board using this (hp690 specifically), and it just so
happens that it's only physically discontiguous at the "normal" P1 offset.  If
we bump up the P1 offset, it's possible to hit a shadowed region of memory
where we suddenly become magically contiguous.

As people have been using this shadowed region workaround for quite some time
(and without any adverse effects), it's time to drop the left over discontig
bits that no longer have any practical use (it was always very much
hp690-centric to begin with).

Paul Mundt d5cb978353 [PATCH] sh: SuperHyway support for SH4-202
This adds support for the relatively quirky (ie, not in line with any known
documentation, and amazed it works at all) SuperHyway implementation on
SH4-202.  This depends on the earlier SuperHyway patch for multiple block
support and VCR refactoring.

On PPC405GP/GPR it should be possible to enable PCI support, even when the
internal PCI arbiter is disabled (e.g.  when using an external PCI
arbiter).  The removed code didn't allow this, and also generated a warning
on PPC405EP platforms.

Roland Dreier fcc188e7fd [PATCH] ppc32: Allow ERPN for early serial to depend on CPU type
The PowerPC 440SPe supports up to 16 GB of RAM, and therefore its IO registers
are at 0x4_xxxx_xxxx instead of being at 0x1_xxxx_xxxx like most other PPC 440
chips.  To allow for this, this patch moves the definition of the ERPN used
for mapping UART0 from being hard-coded in the head_44x.S assembly code to
being defined in ibm44x.h.
