Recently, we started seeing this on allmodconfig builds:
CC mm/memcontrol.o
{standard input}: Assembler messages:
{standard input}:4076: Error: operands mismatch -- statement `subl 12(%fp),170(%a0)' ignored
Correct the asm constraint, like done for m68knommu.

LibSegFault uses piggybacks sc_fpstate field of the `struct sigcontext'
and this patch avoids LibSegFault overflowing this field. Also this
removes an unnecessary divergence from classic m68k.

Commit ef0658f3de484bf9b173639cd47544584e01efa5 changed precision
from int to s8.
There is existing kernel code that uses a larger precision.
An example from the audit code:
vsnprintf(...,..., " msg='%.1024s'", (char *)data);
which overflows precision and truncates to nothing.
Extending precision size fixes the audit system issue.
Other changes:
Change the size of the struct printf_spec.type from u16 to u8 so
sizeof(struct printf_spec) stays as small as possible.
Reorder the struct members so sizeof(struct printf_spec) remains 64 bits
without alignment holes.
Document the struct members a bit more.

When any temperature sensor type is changed, the corresponding
temperature value needs to be updated. The register caching mechanism
may delay this update, so we want to invalidate the cache to force an
immediate update.

Currently, if someone tries to set the thermal sensor type to an
unsupported value, subsequent accesses to the chip may temporarily
show the sensor in question as disabled. Use a temporary variable
and only update the cached value on success, to prevent such
confusion.

Temperature channels can be used in 2 different modes (thermistor and
thermal diode) and we don't know which one, if any, is correct for
every given board. So don't arbitrarily choose one. Instead, leave the
temperature channels untouched. They can be configured from user-space
if needed anyway.

I discovered two issues.
First the previous sht15_calc_temp() loop did not iterate through the
temppoints array since the (data->supply_uV > temppoints[i - 1].vdd)
test is always true in this direction.
Also the two-points linear interpolation function was returning biased
values due to a stray division by 1000 which shouldn't be there.
[JD: Also change the default value for d1 from 0 to something saner.]

This is a partial revert of 4cd8b5e2a159 "lguest: use KVM hypercalls";
we revert to using (just as questionable but more reliable) int $15 for
hypercalls. I didn't revert the register mapping, so we still use the
same calling convention as kvm.
KVM in more recent incarnations stopped injecting a fault when a guest
tried to use the VMCALL instruction from ring 1, so lguest under kvm
fails to make hypercalls. It was nice to share code with our KVM
cousins, but this was overreach.

It's only used by cmpxchg8b_emu (see db677ffa5f5a for the gory
details), and fixing that to be paravirt aware would be more work than
simply ignoring it (and AFAICT only help lguest). This makes lguest
work on machines which have cmpxchg8b, for kernels compiled for older
processors.
(We can't emulate it properly: the popf which expects to restore interrupts
does not trap).

Use a separate class for ceph sockets to prevent lockdep confusion.
Because ceph sockets only get passed kernel pointers, there is no
dependency from sk_lock -> mmap_sem. If we share the same class as other
sockets, lockdep detects a circular dependency from
mmap_sem (page fault) -> fs mutex -> sk_lock -> mmap_sem
because dependencies are noted from both ceph and user contexts. Using
a separate class prevents the sk_lock(ceph) -> mmap_sem dependency and
makes lockdep happy.

This simplifies the calling convention, and fixes a bug where we queue a
capsnap with a context other than i_head_snapc (the one that matches the
dirty pages). The result was a BUG at fs/ceph/caps.c:2178 on writeback
completion when a capsnap matching the writeback snapc could not be found.

Found by kmemleak.
If request_resource() fails, we leak the struct resource we
allocated to represent the IOMMU mapping area.
This actually happens on sun4v machines because the IOMEM area is only
reported sans the IOMMU region, unlike all previous systems. I'll
need to fix that at some point, but for now fix the leak.

The only reference we store to this memory is in the form of a
physical address, so kmemleak can't see it.
Add a kmemleak_not_leak() annotation.
It's probably useful to be able to look at a dump of these things
either via debugfs or similar, and thus we could at some point store
them in some kind of table and therefore get rid of this annotation.

It's the only way we'll be able to implement the function

If we are in an NMI then doing a plain raw_local_irq_disable() will
write PIL_NORMAL_MAX into %pil, which is lower than PIL_NMI, and thus
we'll re-enable NMIs and recurse.
Doing a simple:
%pil = %pil | PIL_NORMAL_MAX
does what we want, if we're already at PIL_NMI (15) we leave it at
that setting, else we set it to PIL_NORMAL_MAX (14).
This should get the function tracer working on sparc64.
