Paolo 'Blaisorblade' Giarrusso 3a02d6c051 [PATCH] uml: don't remove umid files in conflict case
Only remove the UML pidfile and management socket if we created them.
Currently in case two UMLs are started with the same umid, the second will
remove the first's ones.

Probably we should also panic() at that point, not sure however.

Benjamin Herrenschmidt 0365ba7fb1 [PATCH] ppc64: SMU driver update & i2c support
The SMU is the "system controller" chip used by Apple recent G5 machines
including the iMac G5.  It drives things like fans, i2c busses, real time
clock, etc...

The current kernel contains a very crude driver that doesn't do much more
than reading the real time clock synchronously.  This is a completely
rewritten driver that provides interrupt based command queuing, a userland
interface, and an i2c/smbus driver for accessing the devices hanging off
the SMU i2c busses like temperature sensors.  This driver is a basic block
for upcoming work on thermal control for those machines, among others.

Anton Blanchard 586a90eb4c [PATCH] ppc64: Fix LPAR regression
The recent iommu fix broke booting on some POWER4 and POWER5 LPAR boxes.

It looks like we have been calling the non LPAR iommu_dev_setup on LPAR
machines for a while. The recent iommu fix caused that code path to
fail.

It looks like we just need to hook up the devices iommu_table to the
parents one, so do that instead of calling iommu_dev_setup_pSeries and
crossing the streams.

Michael Ellerman 4c55130b2a ppc64 iSeries: Update create_pte_mapping to replace iSeries_bolt_kernel()
early_setup() calls htab_initialize() which is similar, but not identical
to iSeries_bolt_kernel().

On iSeries the Hypervisor has already inserted some ptes for us, and we
simply have to detect that and bolt them. iSeries_hpte_bolt_or_insert()
implements that logic.

For the case of a non-existing pte we just call iSeries_hpte_insert(). This
appears to work, although it's not entirely equivalent to the old code in
iSeries_make_pte() which panicked if we got a secondary slot. Not sure if
that's important.

Finally we call iSeries_hpte_bolt_or_insert() from create_pte_mapping(),
which is called from htab_initialize() for each lmb region.

David S. Miller bff06d5522 [SPARC64]: Rewrite bootup sequence.
Instead of all of this cpu-specific code to remap the kernel
to the correct location, use portable firmware calls to do
this instead.

What we do now is the following in position independant
assembler:

	chosen_node = prom_finddevice("/chosen");
	prom_mmu_ihandle_cache = prom_getint(chosen_node, "mmu");
	vaddr = 4MB_ALIGN(current_text_addr());
	prom_translate(vaddr, &paddr_high, &paddr_low, &mode);
	prom_boot_mapping_mode = mode;
	prom_boot_mapping_phys_high = paddr_high;
	prom_boot_mapping_phys_low = paddr_low;
	prom_map(-1, 8 * 1024 * 1024, KERNBASE, paddr_low);

and that replaces the massive amount of by-hand TLB probing and
programming we used to do here.

The new code should also handle properly the case where the kernel
is mapped at the correct address already (think: future kexec
support).

Consequently, the bulk of remap_kernel() dies as does the entirety
of arch/sparc64/prom/map.S

We try to share some strings in the PROM library with the ones used
at bootup, and while we're here mark input strings to oplib.h routines
with "const" when appropriate.

There are many more simplifications now possible.  For one thing, we
can consolidate the two copies we now have of a lot of cpu setup code
sitting in head.S and trampoline.S.

This is a significant step towards CONFIG_DEBUG_PAGEALLOC support.

David S. Miller 2bdb3cb265 [SPARC64]: Remove unnecessary paging_init() cruft.
Because we don't access the PAGE_OFFSET linear mappings
any longer before we take over the trap table from the
firmware, we don't need to load dummy mappings there
into the TLB and we don't need the bootmap_base hack
any longer either.

While we are here, check for a larger than 8MB kernel
and halt the boot with an error message.  We know that
doesn't work, so instead of failing mysteriously we
should let the user know exactly what's wrong.

This was kind of ugly, and actually buggy.  The bug was that

the 'prompmd' was allocated in physical memory > 4GB we'd
croak because the obp_iaddr_patch and obp_daddr_patch things
only supported a 32-bit physical address.

So fix this by just loading the appropriate values from two
variables in the kernel image, which is locked into the TLB
and thus accesses to them can't cause a recursive TLB miss.

line.  (Unfortunately, pSeries OF sort-of requires real mode and Apple OF
sort-of requires virtual mode, and both tend to be unhappy if no notes
section specifies the mode at all).

However, we forgot to add zImage.vmode to the default G5 build. This

that assumed no more than 7 busses per PHB failed miserably.

Big thanks to Olaf Hering for helping me test this, he's got one of the few
machines that broke from the previous logic.

Also, to be a bit smarter at detecting the need for a PHB-level IOMMU table
by checking for the presence of an ISA bus.  Only PHBs with ISA bridges
should need the PHB-level table.

Paul Mackerras d79e743e9f [PATCH] ppc64: Fix PCI flags when using OF device tree
My code to set up the PCI tree from the Open Firmware device tree was
setting IORESOURCE_* flags on the resources for the devices, but not
the PCI_BASE_ADDRESS_* flags.  This meant that some drivers
misbehaved, and /proc/pci showed the wrong types for the resources.
This fixes it.

Because we use byte loads/stores to cons up the value

setting to take care of this for us.  So do it by hand.

This case is triggered by drivers/block/aoe/aoecmd.c in the
ataid_complete() function where it goes:

		/* word 100: number lba48 sectors */
		ssize = le64_to_cpup((__le64 *) &id[100<<1]);

This &id[100<<1] address is 4 byte, rather than 8 byte aligned,
thus triggering the unaligned exception.

Basically, this extends original dp264 fixup to all dp264 variations.
Here is one minor change: mask out bits 4-7 of a value assigned by SRM,
because
- newer consoles report ISA IRQs with offset 0xe0;
- even if console IRQ value is bogus, we'll have a value < 16
  so it should be harmless as it won't clash with native IRQs.

Building a kernel for IXDP425 currently includes the machine descriptors
for IXDP465 and PRPMC1100 even if those machines are not configured.
This means we can build a kernel that boots on those machines even
though the machine_is_xxx() macro will always return 0 and other bits
such as PCI won't be compiled in. This can lead to many wasted hours
wondering what you have done to your kernel to make it randomly crash

fails, it properly closes the opened file descriptor and returns.  However,
the close resets errno to 0, and the 'return errno' that follows returns 0
rather than the value that ioctl set.  This caused the caller to believe that
the device open succeeded and had opened file descriptor 0, which caused no
end of interesting behavior.

The rest of this patch is a pass through the UML sources looking for places
where errno could be reset before being passed back out.  A common culprit is
printk, which could call write, being called before errno is returned.

In some cases, where the code ends up being much smaller, I just deleted the
printk.

There was another case where a caller of run_helper looked at errno after a
failure, rather than the return value of run_helper, which was the errno value
that it wanted.

Jeff Dike 3eddddcf23 [PATCH] uml: breakpoint an arbitrary thread
This patch implements a stack trace for a thread, not unlike sysrq-t does.
The advantage to this is that a break point can be placed on showreqs, so that
upon showing the stack, you jump immediately into the debugger.  While sysrq-t
does the same thing, sysrq-t shows *all* threads stacks.  It also doesn't work
right now.  In the future, I thought it might be acceptable to make this show
all pids stacks, but perhaps leaving well enough alone and just using sysrq-t
would be okay.  For now, upon receiving the stack command, UML switches
context to that thread, dumps its registers, and then switches context back to
the original thread.  Since UML compacts all threads into one of 4 host
threads, this sort of mechanism could be expanded in the future to include
other debugging helpers that sysrq does not cover.

Note by jdike - The main benefit to this is that it brings an arbitrary thread
back into context, where it can be examined by gdb.  The fact that it dumps it
stack is secondary.  This provides the capability to examine a sleeping
thread, which has existed in tt mode, but not in skas mode until now.

Also, the other threads, that sysrq doesn't cover, can be gdb-ed directly
anyway.

Linus Torvalds 1619cca292 Partially revert "Fix time going twice as fast problem on ATI Xpress chipsets"
Commit 66759a01ad introduced the fix for
time ticking too fast on some boards by disabling one of the doubly
connected timer pins on ATI boards.

However, it ends up being _much_ too broad a brush, and that just makes
some other ATI boards not work at all since they now have no timer
source.

So disable the automatic ATI southbridge detection, and just rely on
people who see this problem disabling it by hand with the option
"disable_timer_pin_1" on the kernel command line.

Maybe somebody can figure out the proper tests at a later date.

Hugh Dickins 2fd4ef85e0 [PATCH] error path in setup_arg_pages() misses vm_unacct_memory()
Pavel Emelianov and Kirill Korotaev observe that fs and arch users of
security_vm_enough_memory tend to forget to vm_unacct_memory when a
failure occurs further down (typically in setup_arg_pages variants).

These are all users of insert_vm_struct, and that reservation will only
be unaccounted on exit if the vma is marked VM_ACCOUNT: which in some
cases it is (hidden inside VM_STACK_FLAGS) and in some cases it isn't.

So x86_64 32-bit and ppc64 vDSO ELFs have been leaking memory into
Committed_AS each time they're run.  But don't add VM_ACCOUNT to them,
it's inappropriate to reserve against the very unlikely case that gdb
be used to COW a vDSO page - we ought to do something about that in
do_wp_page, but there are yet other inconsistencies to be resolved.

The safe and economical way to fix this is to let insert_vm_struct do
the security_vm_enough_memory check when it finds VM_ACCOUNT is set.

And the MIPS irix_brk has been calling security_vm_enough_memory before
calling do_brk which repeats it, doubly accounting and so also leaking.
Remove that, and all the fs and arch calls to security_vm_enough_memory:
give it a less misleading name later on.

My patch "Separate pci bits out of struct device_node" (commit
1635317fac) had the unfortunate
side-effect that it stopped eeh_init() from working correctly.

It needs the pointers set up by find_and_init_phbs(), but it was being
called just before find_and_init_phbs().  That meant that we didn't
enable EEH (pSeries PCI error recovery) on any devices, and that meant
that on POWER5 systems, the hypervisor wouldn't let us enable memory or
I/O space access to any devices, and their drivers got somewhat
confused.

This fixes it by moving the eeh_init call after find_and_init_phbs.

Sharp's newer range of Zaurus clamshell handhelds, the cxx00's are similar to
the c7x0 series yet different.  This patch series abstracts the differences
and generates a set of common drivers that support both series of devices.  It
then adds machine support for Spitz (SL-C3000) and Borzoi (SL-C3100).  Hooks
for Akita (SL-C1000) differences are also added.  The I2C driver for its IO

This patch:

Separate out the Sharp Zaurus c7x0 series specific code from corgi_ssp.c so
that other models such as the cxx00's can share it.  Create sharpsl.h which
will be used to abstract machine/model specifics.

This enables the driver to be used by the Zaurus cxx00 series.

Tom Rini 6a00cbfcf8 [PATCH] ppc32: discard *.exit.text and *.exit.data sections
Discard *.exit.text sections on runtime.  We cannot do this on link time
because of the way BUG macros are implemented.  If "__exit function" calls
one of those macros, __bug_table section will reference this function.
This is similar to ".altinstructions" situation on i386.

*.exit.data seems to be OK in this respect and is discarded on link
time.

Greg Ungerer 9f5757476d [PATCH] m68knommu: startup code for the Drangen Engine 68328 based board
Specialized startup code for the 68328 based DragenEngine board.
It doesn't easily fit into the common 68x328 startup code framework.
It doesn't want any of the common hardware setup to be done here.
