Mikulas Patocka a57ee62749 Fix colors for Mach64
Use the same color-calculating algorithm as in atyfb_imageblit in this
driver or in generic cfb_fillrect.

This patch fixes bad colors when using an accelerator in 15-bit and
16-bit modes.

Tejun Heo d8d9129ea2 libata: implement on-demand HPA unlocking
Implement ata_scsi_unlock_native_capacity() which will be called
through SCSI layer when block layer notices that partitions on a
device extend beyond the end of the device.  It requests EH to unlock
HPA, waits for completion and returns the current device capacity.

This allows libata to unlock HPA on demand instead of having to decide
whether to unlock upfront.  Unlocking on demand is safer than
unlocking by upfront because some BIOSes write private data to the
area beyond HPA limit.  This was suggested by Ben Hutchings.

Tejun Heo 68939ce5fc libata: use the enlarged capacity after late HPA unlock
After late HPA unlock, libata kept using the original capacity
ignoring the new larger native capacity.  Enlarging device on the fly
doesn't cause any harm.  Use the larger native capacity instead.  This
will enable on-demand HPA unlocking.

Tejun Heo f3faf8fc3f sata_nv: don't diddle with nIEN on mcp55
On mcp55, nIEN gets stuck once set and liteon blueray rom iHOS104-08
violates ATA specification and fails to set I on D2H Reg FIS if nIEN
is set when the command was issued.  When the other party is following
the spec, both devices can work fine but when the two flaws are put
together, they can't talk to each other.

mcp55 has its own IRQ masking mechanism and there's no reason to mess
with nIEN in the first place.  Fix it by dropping nIEN diddling from
nv_mcp55_freeze/thaw().

This was originally reported by Cengiz.  Although Cengiz hasn't
verified the fix yet, I could reproduce this problem and verfiy the
fix.  Even if Cengiz is experiencing different or additional problems,
this patch is needed.

Benjamin Herrenschmidt c2cdf6aba0 powerpc/macio: Fix probing of macio devices by using the right of match table
Grant patches added an of mach table to struct device_driver. However,
while he changed the macio device code to use that, he left the match
table pointer in struct macio_driver and didn't update drivers to use
the "new" one, thus breaking the probing.

This completes the change by moving all drivers to setup the "new"
one, removing all traces of the old one, and while at it (since it
changes the exact same locations), I also remove two other duplicates
from struct driver which are the name and owner fields.

Paul Mackerras 79905ad50b agp/uninorth: Fix oops caused by flushing too much
This fixes a sporadic oops at boot on G5 Power Macs.  The table_end
variable has the address of the last byte of the table.  Adding on
PAGE_SIZE means we flush too much, and if the page after the table
is not mapped for any reason, the kernel will oops.  Instead we add
on 1 because flush_dcache_range() interprets its second argument as
the first byte past the range to be flushed.

Dan Carpenter 08a66859e6 FS-Cache: Remove unneeded null checks
fscache_write_op() makes unnecessary checks of the page variable to see if it
is NULL.  It can't be NULL at those points as the kernel would already have
crashed a little higher up where we examined page->index.

Furthermore, unless radix_tree_gang_lookup_tag() can return 1 but no page, a
NULL pointer crash should not be encountered there as we can only get there if
r_t_g_l_t() returned 1.

Arnaldo Carvalho de Melo b5c874f14c perf buildid-list: Fix --with-hits event processing
When we use plain 'perf buildid-list' we use only what is in the buildid
table in the perf.data header. And those have absolute pathnames because
at 'perf record' time we used __perf_session__process_events and that
doesn't sets up the path shortening code in map__new() that happens if
symbol_conf.full_paths is false, the default.

On the other hand, when we use 'perf buildid-list --with-hits' we
process all the events using perf_session__process_events, adding
entries to the global DSO list _after_ removing the current directory
from the DSO name, for presentation purposes.

Because of that we end up having two entries in the DSO list when
recording events for binaries using relative pathnames.

Fix it minimally by setting symbol_conf.full_paths to true when marking
the DSOs with hits in 'perf buildid-list --with-hits', as used by 'perf
archive'

Right fix longer term is to shorten the path only at presentation time.
Will be done for 2.6.36.

Takuya Yoshikawa e30c7c3b30 binfmt_elf_fdpic: Fix clear_user() error handling
clear_user() returns the number of bytes that could not be copied rather than
an error code.  So we should return -EFAULT rather than directly returning the
results.

Without this patch, positive values may be returned to elf_fdpic_map_file()
and the following error handlings do not function as expected.

1.
	ret = elf_fdpic_map_file_constdisp_on_uclinux(params, file, mm);
	if (ret < 0)
		return ret;
2.
	ret = elf_fdpic_map_file_by_direct_mmap(params, file, mm);
	if (ret < 0)
		return ret;

Pierre Tardy c02514850d perf scripts python: Give field dict to unhandled callback
trace_unhandled() callback does not allow to access event fields, this patch
resolves the problem.

It can also been used as a more pythonic and flexible way for script writters
to demux event types

This will for example greatly simplify pytimechart event demux.

Konstantin Stepanyuk 75d9ef1707 perf hist: fix objdump output parsing
hist_entry__annotate() runs objdump with -S option so the output may contain
lines of any format. If a line starts with a colon strtoull() returns 0 and
calculated offset will be negative. This causes perf annotate segfaults.

Make sure that strtoull() has parsed at least one digit.

Joerg Roedel d7f0776975 x86/amd-iommu: Fall back to GART if initialization fails
This patch implements a fallback to the GART IOMMU if this
is possible and the AMD IOMMU initialization failed.
Otherwise the fallback would be nommu which is very
problematic on machines with more than 4GB of memory or
swiotlb which hurts io-performance.

Joerg Roedel e82752d8b5 x86/amd-iommu: Fix crash when request_mem_region fails
When request_mem_region fails the error path tries to
disable the IOMMUs. This accesses the mmio-region which was
not allocated leading to a kernel crash. This patch fixes
the issue.

Peter Zijlstra 02f726949f sched, trace: Fix sched_switch() prev_state argument
For CONFIG_PREEMPT=y kernels the sched_switch(.prev_state) argument isn't
useful because we can get preempted with current->state != TASK_RUNNING
without actually getting removed from the runqueue.

Cure this by treating all preempted tasks as runnable from the tracer's
point of view.

Peter Zijlstra e51fd5e22e sched: Fix wake_affine() vs RT tasks
Mike reports that since e9e9250b (sched: Scale down cpu_power due to RT
tasks), wake_affine() goes funny on RT tasks due to them still having a
!0 weight and wake_affine() still subtracts that from the rq weight.

Since nobody should be using se->weight for RT tasks, set the value to
zero. Also, since we now use ->cpu_power to normalize rq weights to
account for RT cpu usage, add that factor into the imbalance computation.

Michael S. Tsirkin aa989f5e46 virtio-net: pass gfp to add_buf
virtio-net bounces buffer allocations off to
a thread if it can't allocate buffers from the atomic
pool. However, if posting buffers still requires atomic
buffers, this is unlikely to succeed.
Fix by passing in the proper gfp_t parameter.
