Currently arch_remove_kprobes() is only implemented/required for x86_64 and
powerpc. All other architecture like IA64, i386 and sparc64 implementes a

[PATCH] kprobes: changed from using spinlock to mutex
Since Kprobes runtime exception handlers is now lock free as this code path is
now using RCU to walk through the list, there is no need for the
register/unregister{_kprobe} to use spin_{lock/unlock}_isr{save/restore}. The
serialization during registration/unregistration is now possible using just a
mutex.

Turn noatime and nodiratime into per-mount instead of per-sb flags.
After all the preparations this is a rather trivial patch. The mount code
needs to treat the two options as per-mount instead of per-superblock, and
touch_atime needs to be changed to check the new MNT_ flags in addition to
the MS_ flags that are kept for filesystems that are always
noatime/nodiratime but not user settable anymore. Besides that core code
only nfs needed an update because it's leaving atime updates to the server
and thus sets the S_NOATIME flag on every inode, but needs to know whether
it's a real noatime mount for an getattr optimization.
While we're at it I've killed the IS_NOATIME/IS_NODIRATIME macros that were
only used by touch_atime.

o Following patch removes the config dependency of CONFIG_PHYSICAL_START

[PATCH] kdump: x86_64 save cpu registers upon crash
- Saving the cpu registers of all cpus before booting in to the crash
kernel.
- crash_setup_regs will save the registers of the cpu on which panic has
occured. One of the concerns ppc64 folks raised is that after capturing the
register states, one should not pop the current call frame and push new one.
Hence it has been inlined. More call frames later get pushed on to stack
(machine_crash_shutdown() and machine_kexec()), but one will not want to
backtrace those.
- Not very sure about the CFI annotations. With this patch I am getting
decent backtrace with gdb. Assuming, compiler has generated enough
debugging information for crash_kexec(). Coding crash_setup_regs() in pure
assembly makes it tricky because then it can not be inlined and we don't
want to return back after capturing register states we don't want to pop
this call frame.
- Saving the non-panicing cpus registers will be done in the NMI handler
while shooting down them in machine_crash_shutdown.

this frame is popped and new frames are pushed (machine_kexec).
