Currently it's impossible to build a ps3_defconfig which will reboot
without modules installed. This makes it all too easy to find yourself
with a PS3 that won't reboot.
This is because the system manager driver, which provides the reboot
mechanism, is only selectable if PS3_ADVANCED is set, else it defaults
to m. In ps3_defconfig PS3_ADVANCED is not set, therefore the system
manager is built as a module.
It would be desirable IMHO for the defconfig to produce a kernel that
boots and reboots, without needing modules to be installed.

Add function qe_clock_source() which takes a string containing the name of a
QE clock source (as is typically found in device trees) and returns the
matching enum qe_clock value.
Update booting-without-of.txt to indicate that the UCC properties rx-clock
and tx-clock are deprecated and replaced with rx-clock-name and tx-clock-name,
which use strings instead of numbers to indicate QE clock sources.

This patch fixes rounding bug in emulation for double float operating on PowerPC platform.
When pack double float operand, it need to truncate the tail due to the limited precision.
If the truncated part is not zero, the last bit of work bit (totally 3 bits) need to '|' 1.
This patch is completed in _FP_FRAC_SRS_2(X,N,sz) (arch/powerpc/math-emu/op-2.h).
Originally the code leftwards rotates the operand to just keep the truncated part,
then check whether it is zero. However, the number it rotates is not correct when
N is not smaller than _FP_W_TYPE_SIZE, and it will cause the work bit '|' 1 in the improper case.
This patch fixes this issue.

Printk was observed to hang during module unload due to a limited
window of characters that may be sent to the hypervisor. The window
only reexpands when we receive an ack from the HV and the spinlock here
prevents us from ever processing that ack. This fixes it by dropping
the lock before doing the printk, then looping back to the top to
reacquire the lock.

Starting in 2.6.23...
Several reports from X60 users complained that the default Lenovo keymap
issuing EV_KEY KEY_BRIGHTNESS_UP/DOWN input events caused major issues when
the proper brightness support through ACPI video.c was loaded.
Therefore, remove the generation of these events by default, which is the
right thing for T60, X60, R60, T61, X61 and R61 with their latest BIOSes.
Distros that want to misuse these events into OSD reporting (which requires
an ugly hack from hell in HAL) are welcome to set up the key map they need
through HAL. That way, we don't break everyone else's systems.

The ->cap fields of struct acpi_video_device and struct acpi_video_bus
are 1B each, not 4B. The oversized memset()'s corrupted the subsequent
list_head fields. This resulted in silent corruption without
CONFIG_DEBUG_LIST and BUG's with it. This patch uses sizeof() to pass
the proper bounds to the memset() calls and thereby correct the bugs.

This was caught and identified by Greg Onufer.
Since we setup the 256M/4M bitmap table after taking over the trap
table, it's possible for some 4M mapping to get loaded in the TLB
beforhand which later will be 256M mappings.
This can cause illegal TLB multiple-match conditions. Fix this by
setting up the bitmap before we take over the trap table.
Next, __flush_tlb_all() was not doing anything on hypervisor
platforms. Fix by adding sun4v_mmu_demap_all() and calling it.

After looking into the HPT370 manual (now that I have it) and re-checking all
the timing tables, here's what I have discovered:
- at 33 MHz clock, PIO mode 0 timings turned to be overclocked, and all other
PIO modes underclocked;
- at 50 MHz clock, PIO modes 0 to 2 turned to be overclocked;
- at 66 MHz clock, PIO mode 0 was overclocked too.
Finally, the taskfile timing (matching PIO mode 0) turned to be overclocked at
all clock frequencies (and in all manuals)...
The new timings have been tested on HPT370 chip (at 33 MHz PCI clock) and on
HPT371N chip (at both 50 and 66 MHz DPLL clock).

In case of Promise TX4 the first PCI device is located at slot 1
and the second one is at slot 2 so the offset used by pci_get_slot()
should be "+1" and not "+2".

post_transform_command() call in cdrom_newpc_intr() has no effect because
it is done after the request has already been fully completed (rq->bio and
rq->data are always NULL). It was verified to be true regardless whether
INQUIRY command is using DMA or PIO to transfer data (by using modified
Tejun Heo's test-shortsg.c utility and adding a few printk()-s to ide-cd).
This was uncovered thanks to the "blk_end_request: full I/O completion
handler (take 3)" patch series from Kiyoshi Ueda.

* ide_xfer_verbose() fixups:
- beautify returned mode names
- fix PIO5 reporting
- make it return 'const char *'
* Change printk() level from KERN_DEBUG to KERN_INFO in ide_find_dma_mode().
* Add ide_id_dma_bug() helper based on ide_dma_verbose() to check for invalid
DMA info in identify block.
* Use ide_id_dma_bug() in ide_tune_dma() and ide_driveid_update().
As a result DMA won't be tuned or will be disabled after tuning if device
reports inconsistent info about enabled DMA mode (ide_dma_verbose() does the
same checks while the IDE device is probed by ide-{cd,disk} device driver).
* Remove no longer needed ide_dma_verbose().
This patch should fix the following problem with out-of-sync IDE messages
reported by Nick Warne:
hdd: ATAPI 48X DVD-ROM DVD-R-RAM CD-R/RW drive, 2048kB Cache<7>hdd:
skipping word 93 validity check
, UDMA(66)
and later debugged by Mark Lord to be caused by:
ide_dma_verbose()
printk( ... "2048kB Cache");
eighty_ninty_three()
printk(KERN_DEBUG "%s: skipping word 93 validity check\n");
ide_dma_verbose()
printk(", UDMA(66)"
Please note that as a result ide-{cd,disk} device drivers won't report the
DMA speed used but this is intended since now DMA mode being used is always
reported by IDE core code.
v2:
* fixes suggested by Randy:
- use KERN_CONT for printk()-s in ide-{cd,disk}.c
- don't remove argument name from ide_xfer_verbose() declaration
v3:
* Remove incorrect check for (id->field_valid & 1) from ide_id_dma_bug()
(spotted by Sergei).
* "XFER SLOW" -> "PIO SLOW" in ide_xfer_verbose() (suggested by Sergei).
* Fix ide_find_dma_mode() to report the correct mode ('mode' after being
limited by 'req_mode').

Some controllers have been designed on the assumption that all transfers
