The SCSI T10 committee is working on a document describing a standard method for translating ATA<->SCSI, since it being done quite often these days. Some of the recommendations are reasonable, and we implement two here: * Mirror that ATA 'removeable media' bit into INQUIRY output. * Change behavior of INQUIRY output field 'product revision' from the libata software version number to the first 4 bytes of the ATA device's firmware revision number. Rather than cache the firmware revision in struct ata_device, as was/is done with two other strings, I took the opportunity to eliminate the caching of the two other strings, 'vendor' and 'product'. These strings are now retrieved as needed from the IDENTIFY [PACKET] DEVICE info page, since we cache its entire contents. Retrieving a string from the identify-device page is done via the helper function ata_dev_id_string(), which is now exported. This patch winds up making struct ata_device 40 bytes smaller, and the libata core gets a bit smaller as well.

ata_scsi_translate() sets this flag for all ATA->SCSI translated commands, so it need not be done in atapi_xlat(). The now-removed use in atapi_xlat() was also inconsistent WRT PIO versus DMA.

DMADIR bit is necessary for some PATA->SATA bridges. These bridges require the OS driver to specify the data xfer direction, for PACKET (a.k.a. scsi) commands. A reliable DMADIR detection method hasn't yet been developed, and ATAPI is still a WIP, so DMADIR is enabled with an ifdef for now.

It's easier to do it this way, than polling, at the moment. Also, fix a test in ata_scsi_translate that was incorrectly erroring-out non-data commands.

* now that ATAPI is close to working, making ATAPI DMA interrupts in ata_host_intr * remove unnecessary space character in printk() output (oh, the horror)

Remove unused 'done_late' arg to ata_qc_complete(), which was never useful in 2.4, and never used at all in 2.6. This allows us to eliminate the same arg from ata_dma_complete(), and also make it more correct by passing the command rather than the ATA port structure as arg0.

x86_64 has an incorrect ffs() implementation. The asm uses "g" instead of "rm" for the bsfl instruction. (This was spotted by Yuri Per.) bsfl does not accept constant values but only memory or register ones. On i386 the correct "rm" is used. This causes NTFS build to fail as gcc optimizes a variable into a constant and ffs() then fails to assemble.

This fixes a bug where different partitions were assigned the same MAC address. Also, according to Anton, gcc 3.5 didn't like our mac_addr_p gymnastics, so this ends up fixing that as well.

From: Stephen Rothwell <sfr@canb.auug.org.au> It is possible to attach a virtual disk to a logical partition on an iSeries machine so that it is read only to the partition. This patch allows Linux to use such virtual disks.

From: Paul Mackerras <paulus@samba.org> After I sent the recent patch to include/asm-ppc64/io.h which put stronger barriers in the I/O accessor macros, Paul McKenney pointed out to me that a writex/outx could still slide out from inside a spinlocked region. This patch makes the barriers a bit stronger so that this can't happen. It means that we need to use a sync instruction for wmb (a full "heavyweight" sync), since drivers rely on wmb for ordering between writes to system memory and writes to a device. I have left smb_wmb() as a lighter-weight barrier that orders stores, and doesn't impose an ordering between cacheable and non-cacheable accesses (the amusingly-named eieio instruction). I am assuming here that smp_wmb is only used for ordering stores to system memory so that another cpu will see them in order. It can't be used for enforcing any ordering that a device will see, because it is just a gcc barrier on UP. This also changes the spinlock/rwlock unlock code to use lwsync ("light-weight sync") rather than eieio, since eieio doesn't order loads, and we need to ensure that loads stay inside the spinlocked region.

From: Paul Mackerras <paulus@samba.org> When I sent the patch to uninline the spinlocks, I inadvertently left out the change to arch/ppc64/Kconfig which defines the config symbol for inlining the locks (CONFIG_SPINLINE now). This patch adds it. It also adds a symbol CONFIG_PPC_SPLPAR which enables the code for calling the hypervisor on shared-processor logically-partitioned system to yield the physical processor to the lock holder when spinning. (The code that depends on this symbol is already present in arch/ppc64/lib/locks.c.)

From: Paul Mackerras <paulus@samba.org> Matt Porter's recent changes broke the compile for non-4xx ppc32 systems, unfortunately. I get an error that mfdcr is not defined in include/asm-ppc/ocp.h when compiling for powermac (reasonable, since the mfdcr instruction only exists on 4xx processors). The patch below fixes it.
