899e1bc573 ide: Add missing base addresses for falconide and macide
commit 29dd59755a ("ide: remove ide_setup_ports")
forgot to take into account the base addresses for the CONTROL registers for
falconide and macide, as pointed out by Michael Schmitz.

Falconide was tested on Aranym.

I can't remove the equivalent from sparc32 yet as some

667bc389c7 [SPARC]: Kill 'prom_palette'.
The idea of this thing is we could save/restore the firmware's
palette when breaking in and out of the firmware prompt.

Only one driver implemented this (atyfb) and it's value is
questionable.  If you're just debugging you don't really
care that the characters end up being purple or whatever.

And we can provide better debugging and firmware command
facilities with minimal in-kernel console I/O drivers.

4ef110141b [POWERPC] spufs: fix scheduler starvation by idle contexts
2.6.25 has a regression where we can starve the scheduler by creating
(N_SPES+1) contexts, then running them one at a time.

The final context will never be run, as the other contexts are loaded on
the SPEs, none of which are repoted as free (ie, spu->alloc_state !=
SPU_FREE), so spu_get_idle() doesn't give us a spu to run on. Because
all of the contexts are stopped, none are descheduled by the scheduler
tick, as spusched_tick returns if spu_stopped(ctx).

This change replaces the spu_stopped() check with checking for SCHED_IDLE
in ctx->policy. We set a context's policy to SCHED_IDLE when we're not
in spu_run(). We also favour SCHED_IDLE contexts when looking for contexts
to unbind, but leave their timeslice intact for later resumption.

This patch fixes the following test in the spufs-testsuite:

drivers/lguest/x86/switcher_32.S:(.text+0x3815f8):

imply guest support, so now they're separate these bugs come out).

Lguest guest support and host support are separate config options:
they used to be tied together. Sort out which parts of asm-offsets are
needed for Guest and Host.

31eedd823c x86: zap invalid and unused pmds in early boot
The early boot code maps KERNEL_TEXT_SIZE (currently 40MB) starting
from __START_KERNEL_map. The kernel itself only needs _text to _end
mapped in the high alias. On relocatible kernels the ASM setup code
adjusts the compile time created high mappings to the relocation. This
creates invalid pmd entries for negative offsets:

0xffffffff80000000 -> pmd entry: ffffffffff2001e3
It points outside of the physical address space and is marked present.

This starts at the virtual address __START_KERNEL_map and goes up to
the point where the first valid physical address (0x0) is mapped.

Zap the mappings before _text and after _end right away in early
boot. This removes also the invalid entries.

Furthermore it simplifies the range check for high aliases.

51af33e8e4 RDMA/nes: Fix possible array overrun
In nes_create_qp(), the test

	if (nesqp->mmap_sq_db_index > NES_MAX_USER_WQ_REGIONS) {

is used to error out if the db_index is too large; however, if the
test doesn't trigger, then the index is used as

	nes_ucontext->mmap_nesqp[nesqp->mmap_sq_db_index] = nesqp;

and mmap_nesqp is declared as

	struct nes_qp      *mmap_nesqp[NES_MAX_USER_WQ_REGIONS];

which leads to an array overrun if the index is exactly equal to
NES_MAX_USER_WQ_REGIONS.  Fix this by bailing out if the index is
greater than or equal to NES_MAX_USER_WQ_REGIONS.

This was spotted by the Coverity checker (CID 2162).

will generate a Non-maskable Interrupt (NMI) 9 seconds before physically
resetting the server, by removing power, so that the event can be logged to
the HP Integrated Management Log (IML), a Non-Volatile Random Access Memory
(NVRAM). The logging of the event is performed using the HP ProLiant ROM via
an Industry Standard access known as a BIOS Service Directory Entry.

Still panic on unsolicited MSGOUT because this would represent a

7d1abbe824 [SCSI] megaraid: outb_p extermination
From conversations with the maintainers the _p isn't needed so kill it.
That removes the last non ISA _p user from the SCSI layer to my knowledge.

2939deaab2 [SCSI] mpt fusion: kill warnings in mptbase.h on parisc64
Verified all the arches necessary select the CONFIG_64BIT symbol. This
also kills the warning (since it was using the 32-bit case) on parisc64
and mips64.

cb84e2d2ff [SCSI] aic94xx: fix REQ_TASK_ABORT and REQ_DEVICE_RESET
This driver has been failing under heavy load with

aic94xx: escb_tasklet_complete: REQ_TASK_ABORT, reason=0x6
aic94xx: escb_tasklet_complete: Can't find task (tc=4) to abort!

The second message is because the driver fails to identify the task
it's being asked to abort.  On closer inpection, there's a thinko in
the for each task loop over pending tasks in both the REQ_TASK_ABORT
and REQ_DEVICE_RESET cases where it doesn't look at the task on the
pending list but at the one on the ESCB (which is always NULL).

Fix by looking at the right task.  Also add a print for the case where
the pending SCB doesn't have a task attached.

Not sure if this will fix all the problems, but it's a definite first
step.

    [SCSI] ses: add new Enclosure ULD

changes:
1. change char to unsigned char to avoid type change later.
2. preserve len for page1
3. need to move desc_ptr even the entry is not enclosure_component_device/raid.
   so keep desc_ptr on right position
4. record page7 len, and double check if desc_ptr out of boundary before touch.
5. fix typo in subenclosure checking: should use hdr_buf instead.

27d0fe1894 V4L/DVB (7194): cx88-mpeg: Allow concurrent access to cx88-mpeg devices
It currently isn't possible to open the frontend device of cx88-mpeg devices
(DVB or Blackbird) multiple times concurrently. (for instance, to attach a
signal monitoring tool while reading a stream, or to send a frequency change
ioctl) This patch fixes that condition.

5caf51342c V4L/DVB (7188): radio-si470x version 1.0.6
This patch combines all the finished discussions and its resulting patches from
the mailing list.

The version 1.0.6 is mainly influenced by Oliver Neukum. He found a lot of
small issues, that are fixed with this patch now. For me the most interesting
thing is, that it's now safer to use it on other architectures.

The history for version 1.0.6 is:
- fixed coverity checker warnings in *_usb_driver_disconnect
- probe()/open() race by correct ordering in probe()
- DMA coherency rules by separate allocation of all buffers
- use of endianness macros
- abuse of spinlock, replaced by mutex
- racy handling of timer in disconnect, replaced by delayed_work
- racy interruptible_sleep_on(), replaced with wait_event_interruptible()
- handle signals in read()

The driver is tested with all Debian/testing radio programs and rdsd. The patch
is tested against checkpatch.pl v1.12.
