Frédéric Riss 40c373cc3a [PATCH] EFI x86: pass firmware call parameters on the stack
When calling into the EFI firmware, the parameters need to be passed on
the stack. The recent change to use -mregparm=3 breaks x86 EFI support.
This patch is needed to allow the new Intel-based Macs to suspend to ram
(efi.get_time is called during the suspend phase).

John Keller 72253943f7 [PATCH] Altix: more ACPI PRT support
The SN Altix platform does not conform to the IOSAPIC IRQ routing model.
Add code in acpi_unregister_gsi() to check if (acpi_irq_model ==
ACPI_IRQ_MODEL_PLATFORM) and return.

Due to an oversight, this code was not added previously when
similar code was added to acpi_register_gsi().

Magnus Damm 29a002776b [PATCH] kexec: Avoid migration of already disabled irqs (ia64)
This patch fixes up ia64 kexec support for HP rx2620 hardware.  It does
this by skipping migration of already disabled irqs.  This is most likely a
problem on other ia64 platforms as well, but I've only been able to
reproduce it on one machine so far.

The full story is that handle_bad_irq() gets invoked before starting the
new kernel without this patch.  This seems to happen when fixup_irqs()
calls generic_handle_irq() on already migrated (and disabled) irqs.  So by
avoiding migration of disabled irqs we stay away of handle_bad_irq().

The code has been tested on three different ia64 machines, all with good
results.  It is possible to trigger the same bug by offlining a processor
using echo 0 > /sys/devices/system/cpu/cpuX/online.

More detailed information is available in the following mail thread:

Linus Torvalds 435f8a605d Revert "[PATCH] fix typo in geode_configre()@cyrix.c"
This reverts commit e4f0ae0ea6.

It's not wrong, but it's not right either, and everybody seems to agree
that the right fix is probably to do the ccr3 write after the ccr4 one
(and that we also should clean it up a bit).  And after that we need to
really validate that all the bits that we write to ccr4 actually do
work.

The old 2.6.19 code was insane, and basically didn't change ccr4 at all
(even though it certainly looks like it was the *intent* to do so).  So
let's revert the change that may fix things, just because it's not what
was actually ever tested when the code was written, even if it _was_ the
intent.

There's a discussion on http://lkml.org/lkml/2007/1/9/63 that was
started by the patch that now gets reverted, and that discussion may
well contain the proper long-term fix.

Al Viro 2a3d4f1f1f [PATCH] __crc_... is intended to be absolute
i386 boot/compressed/relocs checks for absolute symbols and warns about
unexpected ones.  If you build with modversions, you get ~2500 warnings
about __crc_<symbol>.  These suckers are really absolute symbols - we
do _not_ want to modify them on relocation.

They are generated by genksyms - EXPORT_... generates a weak alias, then
genksyms produces an ld script with __crc_<symbol> = <checksum> and it's
fed to ld to produce the final object file.  Their only use is to match
kernel and module at modprobe time; they _must_ be absolute.

boot/compressed/relocs has a whitelist of known absolute symbols, but
it doesn't know about __crc_... stuff.  As the result, we get shitloads
of false positives on any ld(1) version.

Eric W. Biederman 8339f0008c [PATCH] i386: In assign_irq_vector look at all vectors before giving up
When the world was a simple and static place setting up irqs was easy.
It sufficed to allocate a linux irq number and a find a free cpu
vector we could receive that linux irq on.  In those days it was
a safe assumption that any allocated vector was actually in use
so after one global pass through all of the vectors we would have
none left.

These days things are much more dynamic with interrupt controllers
(in the form of MSI or MSI-X) appearing on plug in cards and linux
irqs appearing and disappearing.  As these irqs come and go vectors
are allocated and freed,  invalidating the ancient assumption that all
allocated vectors stayed in use forever.

So this patch modifies the vector allocator to walk through every
possible vector before giving up, and to check to see if a vector
is in use before assigning it.  With these changes we stop leaking
freed vectors and it becomes possible to allocate and free irq vectors
all day long.

This changed was modeled after the vector allocator on x86_64 where
this limitation has already been removed.  In essence we don't update
the static variables that hold the position of the last vector we
allocated until have successfully allocated another vector.  This
allows us to detect if we have completed one complete scan through
all of the possible vectors.

David S. Miller 86d43258bc [SPARC64]: Set g4/g5 properly in sun4v dtlb-prot handling.
Mirror the logic in the sun4u handler, we have to update
both registers even when we branch out to window fault
fixup handling.

The way it works is that if we are in etrap processing a
fault already, g4/g5 holds the original fault information.
If we take a window spill fault while doing etrap, then
we put the window spill fault info into g4/g5 and this is
what the top-level fault handler ends up processing first.

Then we retry the originally faulting instruction, and
process the original fault at that time.

This is all necessary because of how constrained the trap
registers are in these code paths.  These cases trigger
very rarely, so even if there is some performance implication
it's doesn't happen very often.  In fact the rarity is why
it took so long to trigger and find this particular bug.

David Woodhouse 8cdf92a98f Fix Maple PATA IRQ assignment.
On the Maple board, the AMD8111 IDE is in legacy mode... except that it
appears on IRQ 20 instead of IRQ 15. For drivers/ide this was handled by
the architecture's "pci_get_legacy_ide_irq()" function, but in libata we
just hard-code the numbers 14 and 15.

This patch provides asm-powerpc/libata-portmap.h which maps the IRQ as
appropriate, having added a pci_dev argument to the
ATA_{PRIM,SECOND}ARY_IRQ macros.

There's probably a better way to do this -- especially if we observe
that the _only_ case in which this seemingly-generic
"pci_get_legacy_ide_irq()" function returns anything other than 14 and
15 for primary and secondary respectively is the case of the AMD8111 on
the Maple board -- couldn't we handle that with a special case in the
pata_amd driver, or perhaps with a PCI quirk for Maple to switch it into
native mode during early boot and assign resources properly?

Roland McGrath f47aef55d9 [PATCH] i386 vDSO: use VM_ALWAYSDUMP
This patch fixes core dumps to include the vDSO vma, which is left out now.
It removes the special-case core writing macros, which were not doing the
right thing for the vDSO vma anyway.  Instead, it uses VM_ALWAYSDUMP in the
vma; there is no need for the fixmap page to be installed.  It handles the
CONFIG_COMPAT_VDSO case by making elf_core_dump use the fake vma from
get_gate_vma after real vmas in the same way the /proc/PID/maps code does.

This changes core dumps so they no longer include the non-PT_LOAD phdrs from
the vDSO.  I made the change to add them in the first place, but in turned out
that nothing ever wanted them there since the advent of NT_AUXV.  It's cleaner
to leave them out, and just let the phdrs inside the vDSO image speak for
themselves.

Roland McGrath a1f3bb9ae4 [PATCH] Fix CONFIG_COMPAT_VDSO
I wouldn't mind if CONFIG_COMPAT_VDSO went away entirely.  But if it's there,
it should work properly.  Currently it's quite haphazard: both real vma and
fixmap are mapped, both are put in the two different AT_* slots, sysenter
returns to the vma address rather than the fixmap address, and core dumps yet
are another story.

This patch makes CONFIG_COMPAT_VDSO disable the real vma and use the fixmap
area consistently.  This makes it actually compatible with what the old vdso
implementation did.

Alexey Dobriyan 48c35b2d24 [MIPS] There is no __GNUC_MAJOR__
Gcc major version number is in __GNUC__. As side effect fix checking
with sparse if sparse was built with gcc 4.1 and mips cross-compiler
is 3.4.

Sparse will inherit version 4.1, __GNUC__ won't be filtered from
"-dM -E -xc" output, sparse will pick only new major, effectively becoming
gcc version 3.1 which is unsupported.

Linus Walleij d4e1c889c1 [ARM] 4102/1: Allow for PHYS_OFFSET on any valid 2MiB address
This patchs allows the offset to the first page of
physical memory to be on any 2MB boundary
whereas the previous code could only handle psysical
offset to any 16MB boundary (0xNN000000) or any 1MB
boundary below 0x01000000 (e.g. 0x00N00000). The
problem is a consequence of the orr one-byte syntax,
so we fix this and we can place the first bank of
memory at 0x28e00000. I have also included an explicit
check that disallow compilation when PHYS_OFFSET is
not on a 2MiB boundary. head.S would be the proper place
to have this at since this is the first file that
attempts to use PHYS_OFFSET during compile.

Ben Dooks 30f0e0f415 [ARM] 4096/1: S3C24XX: change return code form s3c2410_gpio_getcfg()
The s3c2410_gpio_getcfg() currently returns
a value which is dependant on the GPIO no
passed in. Now we have more generic constants
it is sensible to use those as return codes
so that any function dealing with >1 GPIO
does not need to do it's own number processing.

Since this function is only currently used in
pm.c, it is easy to fixup (and correct pm.c
to use the generic constants)

Ben Dooks 6c3c5bb3c6 [ARM] 4095/1: S3C24XX: Fix GPIO set for Bank A
GPIO bank A can only be output or a special
function, and the regs-gpio.h header has
mistakenly got this as input or output.

The mistake is carried on into the gpio.c
s3c2410_gpio_cfgpin() call which will set the
wrong value if S3C2410_GPIO_OUTPUT is passed.

Andrew Victor 3ea163e44c [ARM] 4089/1: AT91: GPIO wake IRQ cleanup
Cleanup of at91 platform level gpio wake and suspend/resume logic.

The GPIO core now delegates wakeups to the parent AIC by refcounting,
and delegates clock management to the clock API.  This makes these
system modules more independent of each other, which is cleaner and will
also help with the AT91SAM9263 (where some GPIO controllers share the
same irq and clock).
