      Longhaul: add auto enabled "revid_errata" option · 52a2638b
      由 Rafal Bilski 提交于 
      VIA C3 Ezra-T has RevisionID equal to 1, but it needs RevisionKey to be 0
or CPU will ignore new frequency and will continue to work at old
frequency.  New "revid_errata" option will force RevisionKey to be set to
0, whatever RevisionID is.

Additionaly "Longhaul" will not silently ignore unsuccessful transition.
It will try to check if "revid_errata" or "disable_acpi_c3" options need to
be enabled for this processor/system.

Same for Longhaul ver.  2 support.  It will be disabled if none of above
options will work.

 Best case scenario (with patch apllied and v2 enabled):
 longhaul: VIA C3 'Ezra' [C5C] CPU detected.  Longhaul v2 supported.
 longhaul: Using northbridge support.
 longhaul: VRM 8.5
 longhaul: Max VID=1.350  Min VID=1.050, 13 possible voltage scales
 longhaul: f: 300000 kHz, index: 0, vid: 1050 mV
 [...]
 longhaul: Voltage scaling enabled.
 Worst case scenario:
 longhaul: VIA C3 'Ezra-T' [C5M] CPU detected.  Powersaver supported.
 longhaul: Using northbridge support.
 longhaul: Using ACPI support.
 longhaul: VRM 8.5
 longhaul: Claims to support voltage scaling but min & max are both 1.250. Voltage scaling disabled
 longhaul: Failed to set requested frequency!
 longhaul: Enabling "Ignore Revision ID" option.
 longhaul: Failed to set requested frequency!
 longhaul: Disabling ACPI C3 support.
 longhaul: Disabling "Ignore Revision ID" option.
 longhaul: Failed to set requested frequency!
 longhaul: Enabling "Ignore Revision ID" option.

      [SPARC64]: Fix missing load-twin usage in Niagara-1 memcpy. · 25e5566e
      由 David S. Miller 提交于 
      For the case where the source is not aligned modulo 8
we don't use load-twins to suck the data in and this
kills performance since normal loads allocate in the
L1 cache (unlike load-twin) and thus big memcpys swipe
the entire L1 D-cache.

We need to allocate a register window to implement this
properly, but that actually simplifies a lot of things
as a nice side-effect.

      x86_64: increase VDSO_TEXT_OFFSET for ancient binutils · cf8dc57c
      由 Andi Kleen 提交于 
      For some reason old binutils genertate larger headers so increase the text
offset of the vdso to avoid linker errors.

Roland McGrath explains:
  "There are extra symbols in the '.dynsym' section that are responsible
   for the size difference (They also cause corresponding inflation in
   '.gnu.version')

   Older ld's wrongly generated these unneeded symbols in .dynsym.  This
   was fixed not all that long ago (2006); binutils-2.17.50.0.6 might be
   the first fixed version, but I have not verified for sure where the
   cutoff was.

   The unneeded symbols et al from old ld add almost 700 bytes excess.
   This limits fairly tightly the amount by which the actual text and
   data in the vDSO can grow in the future without pushing the whole
   file over 4kb.  If it does grow later on, we should consider changing
   the layout with a config option or something to pack it better
   without that padding, when building the kernel with newer binutils."

      [POWERPC] Fix xics set_affinity code · e48395f1
      由 Anton Blanchard 提交于 
      On a POWER6 machine running 2.6.23-rc8 I sometimes see the following error:

xics_set_affinity: No online cpus in the mask 00000000,00000000,00000000,00000001 for irq 20

In a desperate attempt to get a changelog entry in 2.6.23, I took a look
into it.

It turns out we are passing a real and not a virtual irq into
get_irq_server.  This works for the case where hwirq < NR_IRQS and we
set virq = hwirq.  In my case however hwirq = 590082 and we try and
access irq_desc[590082], slightly past the end at 512 entries.

Lucky we ship lots of memory with our machines.

      [SPARC64]: Fix put_user() calls in binfmt_aout32.c · 8cc8c28a
      由 David S. Miller 提交于 
      argv and envp are pointers to u32's in userspace, so don't
try to put_user() a NULL to them.

Aparently gcc-4.2.x now warns about this, and since we use
-Werror for arch/sparc64 code, this breaks the build.
