[SCSI] sr: partial revert of 24669f75a3231fa37444977c92d1f4838bec1233

The patch

[SCSI] SCSI core kmalloc2kzalloc

Has an incorrect piece in sr_ioctl.c; it changes buffer from kmalloc
to kzalloc, but then removes the clearing of the stack variable struct
packet_command.  This, in turn leaves rubbish in the sense pointer
which the sr_do_ioctl() command then happily writes to ... oops.

Thanks to Mike Christie <michaelc@cs.wisc.edu> for spotting this.

Ok, so here is my first take at satisfying this request.
Be warned, that beyond compiling, and checking that the new module
doesn't immediately blow up, there hasn't yet been a lot of testing.

But this should allow you to comment on the changes, and move forward
with dropping scsi_request from the kernel code.

[PATCH] x86_64: Better ATI timer fix

The previous experiment for using apicmaintimer on ATI systems didn't
work out very well.  In particular laptops with C2/C3 support often
don't let it tick during idle, which makes it useless.  There were also
some other bugs that made the apicmaintimer often not used at all.

I tried some other experiments - running timer over RTC and some other
things but they didn't really work well neither.

I rechecked the specs now and it turns out this simple change is
actually enough to avoid the double ticks on the ATI systems.  We just
turn off IRQ 0 in the 8254 and only route it directly using the IO-APIC.

I tested it on a few ATI systems and it worked there.  In fact it worked
on all chipsets (NVidia, Intel, AMD, ATI) I tried it on.

According to the ACPI spec routing should always work through the
IO-APIC so I think it's the correct thing to do anyways (and most of the
old gunk in check_timer should be thrown away for x86-64).

But for 2.6.16 it's best to do a fairly minimal change:
 - Use the known to be working everywhere-but-ATI IRQ0 both over 8254
   and IO-APIC setup everywhere
 - Except on ATI disable IRQ0 in the 8254
 - Remove the code to select apicmaintimer on ATI chipsets
 - Add some boot options to allow to override this (just paranoia)

In 2.6.17 I hope to switch the default over to this for everybody.

off ACPI because it thought the BIOS was too old.  Some systems don't
boot without ACPI so this was a problem.

I have a full fix by adding new very early DMI detection, but it needs
more testing before it can be merged.  For 2.6.16 let's just turn the
check off.  It never made much sense anyways because there are no x86-64

When compiling a non-default subarch, topology.c is missing from the kernel
build.  This causes builds with CONFIG_HOTPLUG_CPU to fail.  In addition,
on Intel processors with cpuid level > 4, it causes intel_cacheinfo.c to
reference uninitialized data that should have been set up by the initcall

both of these problems.

[PATCH] flags parameter for linkat

I'm currently at the POSIX meeting and one thing covered was the
incompatibility of Linux's link() with the POSIX definition.  The name.
Linux does not follow symlinks, POSIX requires it does.

Even if somebody thinks this is a good default behavior we cannot change this
because it would break the ABI.  But the fact remains that some application
might want this behavior.

We have one chance to help implementing this without breaking the behavior.
 For this we could use the new linkat interface which would need a new
flags parameter.  If the new parameter is AT_SYMLINK_FOLLOW the new
behavior could be invoked.

I do not want to introduce such a patch now.  But we could add the
parameter now, just don't use it.  The patch below would do this.  Can we
get this late patch applied before the release more or less fixes the
syscall API?
