Apparently no ATAPI CD/DVD actually supports REPORT LUNS (in spite of
claiming scsi-3 compliance, where it's mandatory) and worse, some
crash or flake out on being sent the command. This may actually be
due to a conflict between SPC and MMC with MMC not listing REPORT LUNS
as mandatory. The same standards conflict exists for RBC as well.
Fix all of this by reversing the blacklists for CDROM and RBC devices
(i.e. now they have to have the BLIST_REPORTLUNS2 flag set even if the
inquiry data returns scsi-3 compliance).

The code does this:
unsigned char sense[SCSI_SENSE_BUFFERSIZE];
...
scsi_normalize_sense(sense, sizeof(*sense), sshdr)
however the sizeof will return 1 not 96 which means the sense data will
have no valid ASC/ASCQ values. Fix by putting the correct sense size.
The only affected case for this would have been the DV buffer sanity
check failure, which is fortunately quite rare.

If either scsi_complete_async_scans() is called a second time
before the first call has finished, or a host scan is started while
scsi_complete_async_scans() is still sleeping, it would fail to wake up
the other task, which would sleep forever.
I've changed the kernel-doc to make it clear that
scsi_complete_async_scans() only guarantees that scans which started
before it was called are guaranteed to have finished when it returns.
I considered making it wait until all scans are completed, but it can't
guarantee that no more scans will start before it returns anyway, and it
runs the risk of confusing other callers of scsi_complete_async_scans()
for hosts actually scanning.

This is a slight variant on the patch I posted December 16th to fix
libata combined mode handling. The only real change is that we now
correctly also reserve BAR1,2,4. That is basically a neatness issue.
Jeff was unhappy about two things
1. That it didn't work in the case of one channel native one channel
legacy.
This is a silly complaint because the SFF layer in libata doesn't handle
this case yet anyway.
2. The case where combined mode is in use and IDE=n.
In this case the libata quirk code reserves the resources in question
correctly already.
Once the combined mode stuff is redone properly (2.6.21) then the entire
mess turns into a single pci_request_regions() for all cases and all the
ugly resource hackery goes away.
I'm sending this now rather than after running full test suites so that
it can get the maximal testing in a short time. I'll be running tests on
this after lunch.

The fix is to set up the MMU state in two phases: kvm_mmu_create() and

The latest version of kvm doesn't initialize kvm_arch_ops in kvm_init(), which
causes an error with the following sequence.
1. Load the supported arch's module.
2. Load the unsupported arch's module.$B!!(B(loading error)
3. Unload the unsupported arch's module.
You'll get the following error message after step 3. "BUG: unable to handle
to handle kernel paging request at virtual address xxxxxxxx"
The problem here is that the unsupported arch's module overwrites kvm_arch_ops
of the supported arch's module at step 2.
This patch initializes kvm_arch_ops upon loading architecture specific kvm
module, and prevents overwriting kvm_arch_ops when kvm_arch_ops is already set
correctly.

The fallback to PIO mode in the hwif->dma_check() handler doesn't work in
the Intel PIIX and SMsC SLC90E66 IDE drivers because:
- config_drive_for_dma() calls the hwif->speedproc() handler with a wrong
mode number (unbiased by XFER_PIO_0) in case of the PIO fallback;
- hwif->tuneproc() handler doesn't really set the drive's own speed (this
is not fixed as yet).

Some issues were recently turned up with the current specification of what
it means for spi_transfer.tx_buf to be null, as part of transfers which are
(from the SPI protocol driver perspective) pure reads.
Specifically, that it seems better to change the TX behaviour there from
"undefined" to "will shift zeroes". This lets protocol drivers (like the
ads7846 driver) depend on that behavior. It's what most controller drivers
in the tree are already doing (with one exception and one case of driver
wanting-to-oops), it's what Microwire hardware will necessarily be doing,
and it removes an issue whereby certain security audits would need to
define such a value anyway as part of removing covert channels.
This patch changes the specification to require shifting zeroes, and
updates all currently merged SPI controller drivers to do so.
