      [IA64] kprobes arch consolidation build fix · 45e18c22
      由 Harvey Harrison 提交于 
      ia64 named their handler kprobes_fault_handler while all other
arches used kprobe_fault_handler.  Change the function definition
and header declaration.

      [IA64] update efi region debugging to use MB, GB and TB as well as KB · 818c7e86
      由 Simon Horman 提交于 
      When EFI_DEBUG is defined to a non-zero value in arch/ia64/kernel/efi.c,
the efi memory regions are displayed. This patch enhances the
display code in a few ways:

1. Use TB, GB and MB as well as KB as units.
   Although this introduces rounding errors (KB doesn't as
   size is always a multiple of 4Kb), it does make
   things a lot more readable.

   Also as the range is also shown, it is possible to note the exact size
   if it is important. In my experience, the size field is mostly useful
   for getting a general idea of the size of a region.

   On the rx2620 that I use, there actually is an 8TB region (though not
   backed by physical memory, and 8TB really is a lot more readable than
   8589934592KB.

2. pad the size field with leading spaces to further improve readability

   ...
   ... (   8MB)
   ... ( 928MB)
   ... (   3MB)
   ...

   vs

   ...
   ... (8MB)
   ... (928MB)
   ... (3MB)
   ...

3. Pad the attr field out to 64bits using leading zeros,
   to further improve readability.

   ...
   mem05: type= 2, attr=0x0000000000000008, range=[0x0000000004000000-0x000000000481f000) (   8MB)
   mem06: type= 7, attr=0x0000000000000008, range=[0x000000000481f000-0x000000003e876000) ( 928MB)
   mem07: type= 5, attr=0x8000000000000008, range=[0x000000003e876000-0x000000003eb8e000) (   3MB)

   ...

   ...
   mem05: type= 2, attr=0x8, range=[0x0000000004000000-0x000000000481f000) (   8MB)

   mem07: type= 5, attr=0x8000000000000008, range=[0x000000003e876000-0x000000003eb8e000) (   3MB)

   ...

4. Use %d instead of %u for the index field, as i is a signed int.

      [IA64] workaround tiger ia64_sal_get_physical_id_info hang · 6ed0dc5b
      由 Alex Chiang 提交于 
      This fixes regression introduced in 113134fc

Intel Tiger platforms hang when calling SAL_GET_PHYSICAL_ID_INFO
instead of properly returning -1 for unimplemented, so add a
version check.

SGI Altix platforms have an incorrect SAL version hard-coded into
their prom -- they encode 2.9, but actually implement 3.2 -- so
fix it up and allow ia64_sal_get_physical_id_info to keep
working.

      [IA64] Fix irq migration in multiple vector domain · a6cd6322
      由 Kenji Kaneshige 提交于 
      Fix the problem that the following error message is sometimes displayed
at irq migration when vector domain is enabled.

    "Unexpected interrupt vector %d on CPU %d is not mapped to any IRQ!"

The cause of this problem is an interrupt is sent to the previous
target CPU after cleaning up vector to irq mapping table. To clean up
vector to irq map on the previous target CPU safty, change the irq
migration in multiple vector domain as follows. The original idea is
from x86 interrupt management code.

    - Delay vector to irq table cleanup until the interrupts are sent
      to new target CPUs. By this, it is ensured that target CPU is
      completely changed on the interrupt controller side.

    - Even after the interrupts are sent to new target CPUs, there can
      be pended interrupts remaining on the previous target CPU. So we
      need to delay clearning up vector to irq table until the pended
      interrupt is handled. For this, send IPI to the previous target
      CPU with lower priority vector and clean up vector to irq table
      in its handler.

This patch affects only to irq migration code with multiple vector
domain is enabled.

      calibrate_delay() must be __cpuinit, not __{dev,}init.

I've verified that this is correct for all users.

While doing the latter, I also did the following cleanups:
- remove pointless additional prototypes in C files
- ensure all users #include <linux/delay.h>

This fixes the following section mismatches with CONFIG_HOTPLUG=n,
CONFIG_HOTPLUG_CPU=y:
