Lennert Buytenhek d236f5a5f7 [ARM] Orion: use mv643xx_eth driver mbus window handling
Make the Orion 5x platform code use the mbus window handling code
that's in the mv643xx_eth driver, instead of programming the GigE
block's mbus window registers by hand.

David S. Miller dc5dc7e6d7 sparc: Fix SA_ONSTACK signal handling.
We need to be more liberal about the alignment of the buffer given to
us by sigaltstack().  The user should not need to be mindful of all of
the alignment constraints we have for the stack frame.

This mirrors how we handle this situation in clone() as well.

Also, we align the stack even in non-SA_ONSTACK cases so that signals
due to bad stack alignment can be delivered properly.  This makes such
errors easier to debug and recover from.

Finally, add the sanity check x86 has to make sure we won't overflow
the signal stack.

This fixes glibc testcases nptl/tst-cancel20.c and
nptl/tst-cancelx20.c

Christian Borntraeger 0eaeafa10f [S390] s390-kvm: leave sie context on work. Removes preemption requirement
From: Martin Schwidefsky <schwidefsky@de.ibm.com>

This patch fixes a bug with cpu bound guest on kvm-s390. Sometimes it
was impossible to deliver a signal to a spinning guest. We used
preemption as a circumvention. The preemption notifiers called
vcpu_load, which checked for pending signals and triggered a host
intercept. But even with preemption, a sigkill was not delivered
immediately.

This patch changes the low level host interrupt handler to check for the
SIE  instruction, if TIF_WORK is set. In that case we change the
instruction pointer of the return PSW to rerun the vcpu_run loop. The kvm
code sees an intercept reason 0 if that happens. This patch adds accounting
for these types of intercept as well.

The advantages:
- works with and without preemption
- signals are delivered immediately
- much better host latencies without preemption

Martin Schwidefsky 2688905e6a [S390] s390: Optimize user and work TIF check
On return from syscall or interrupt, we have to check if we return to
userspace (likely) and if there is work todo (less likely) to decide
if we handle the work. We can optimize this check: we first check for
the less likely work case and then check for userspace.

This patch is also a preparation for an additional patch, that fixes a bug
in KVM dealing with cpu bound guests.

Hugh Dickins aeed5fce37 x86: fix PAE pmd_bad bootup warning
Fix warning from pmd_bad() at bootup on a HIGHMEM64G HIGHPTE x86_32.

That came from 9fc34113f6 x86: debug pmd_bad();
but we understand now that the typecasting was wrong for PAE in the previous
version: pagetable pages above 4GB looked bad and stopped Arjan from booting.

And revert that cded932b75 x86: fix pmd_bad
and pud_bad to support huge pages.  It was the wrong way round: we shouldn't
weaken every pmd_bad and pud_bad check to let huge pages slip through - in
part they check that we _don't_ have a huge page where it's not expected.

Put the x86 pmd_bad() and pud_bad() definitions back to what they have long
been: they can be improved (x86_32 should use PTE_MASK, to stop PAE thinking
junk in the upper word is good; and x86_64 should follow x86_32's stricter
comparison, to stop thinking any subset of required bits is good); but that
should be a later patch.

Fix Hans' good observation that follow_page() will never find pmd_huge()
because that would have already failed the pmd_bad test: test pmd_huge in
between the pmd_none and pmd_bad tests.  Tighten x86's pmd_huge() check?
No, once it's a hugepage entry, it can get quite far from a good pmd: for
example, PROT_NONE leaves it with only ACCESSED of the KERN_PGTABLE bits.

However... though follow_page() contains this and another test for huge
pages, so it's nice to keep it working on them, where does it actually get
called on a huge page?  get_user_pages() checks is_vm_hugetlb_page(vma) to
to call alternative hugetlb processing, as does unmap_vmas() and others.

|
|    x86-64: introduce struct pci_sysdata to facilitate sharing of ->sysdata
|
|    This patch introduces struct pci_sysdata to x86 and x86-64, and
|    converts the existing two users (NUMA, Calgary) to use it.
|
|    This lays the groundwork for having other users of sysdata, such as
|    the PCI domains work.
|
|    The Calgary bits are tested, the NUMA bits just look ok.

replaces pcibios_scan_root with pci_scan_bus_parented...

but in pcibios_scan_root we have a DMI check:

    dmi_check_system(pciprobe_dmi_table);

when when have several peer root buses this could be called multiple
times (which is bad), so move that call to pci_access_init().

Ben 163ea310b6 x86: remove dell reboot dmi quirk board name match
http://bugzilla.kernel.org/show_bug.cgi?id=10547

Newer Dell OptiPlex 745s hang before rebooting after 'sudo reboot'.

A patch for some versions of the OptiPlex was proposed here --
http://lkml.org/lkml/2007/6/5/59 -- and is included in 2.6.23 and
later kernels, according to
http://lxr.linux.no/linux+v2.6.23/arch/i386/kernel/reboot.c . However,
the DMI_BOARD_NAME ("0WF810") is too restrictive. Newer OptiPlex
machines have a DMI_BOARD_NAME of "0RF703".  I therefore suggest
adding another clause to reboot.c, similar to the one in the original
patch, but matching a DMI_BOARD_NAME of "0RF703".

On further inspection, it seems that there are other DMI_BOARD_NAMEs
for this same machine. They seem to change from time to time, which
means that the current code is fragile. Moreover, using bios reboot
should not break non-SFF OptiPlex 745s, and so a reasonable fix is to
simply drop the match on DMI_BOARD_NAME.

Sam Ravnborg 4c6214c75a kbuild, suspend, x86: fix rebuild of wakeup.bin
In kernel/acpi/realmode/Makefile use the 'always'
variable to say that wakeup.bin should always
be made.

In acpi/Makefile we then do not need to specify the
requested target and we avoid the message from make:

   `arch/x86/kernel/acpi/realmode/wakeup.bin' is up to date.

Add wakeup.lds to list af targets to avoid rebuilding
wakeup.bin - from Roland McGrath.

Thomas Gleixner 48b83d2425 x86: undo visws/numaq build changes
arch/x86/pci/Makefile_32 has a nasty detail. VISWS and NUMAQ build
override the generic pci-y rules. This needs a proper cleanup, but
that needs more thoughts. Undo

commit 895d30935e
    x86: numaq fix
    do not override the existing pci-y rule when adding visws or
    numaq rules.

There is also a stupid init function ordering problem vs. acpi.o

Add comments to the Makefile to avoid tripping over this again.

Remove the srat stub code in discontig_32.c to allow a proper NUMAQ
build.
