Notes ... this time I used Petr's "cogito" tools, instead of raw git
commands.  I'm hugely impressed that generating the diffstat and commit
list takes less than half a second :-)

"git log" seems to have problems interpreting the dates ... looking at the
commit entries, the time is right ... but it appears that git log applies
the timezone correction twice, so the changes I just applied at 14:46 PDT
look like I made them at quarter to five tomorrow morning (+14 hours from
when I did).

    [IA64] cpu hotplug: return offlined cpus to SAL
    
    This patch is required to support cpu removal for IPF systems. Existing code
    just fakes the real offline by keeping it run the idle thread, and polling
    for the bit to re-appear in the cpu_state to get out of the idle loop.
    
    For the cpu-offline to work correctly, we need to pass control of this CPU 
    back to SAL so it can continue in the boot-rendez mode. This gives the
    SAL control to not pick this cpu as the monarch processor for global MCA
    events, and addition does not wait for this cpu to checkin with SAL
    for global MCA events as well. The handoff is implemented as documented in 
    SAL specification section 3.2.5.1 "OS_BOOT_RENDEZ to SAL return State"

    [IA64] ia32_signal.c: erroneous use of memset/memcpy
    
    Found by Alexander Nyberg, improved by Bjorn Helgaas.
    
    - Fix the incorrect argument to sizeof()
    - looks like memcpy() code pass was dervived from code that used
      copy_from_user().  But in this case we are doing to kernel space
      to kernel space copy, so memcpy is the right routine, but it
      doesn't return an error code.
