Detection of an ATAPI taskfile is possible using a simple test on existing information, so there is no need to cache this value in a separate flag (ATA_QCFLAG_ATAPI). Instead, create and use a new helper function is_atapi_taskfile().

* SEEK(6), SEEK(10), and REZERO_UNIT are no-ops. Unconditionally complete these commands with success. * MODE SENSE caching page work: * correct page length * set bit, if read-ahead is disabled * set bit, if writeback caching is enabled (previously, this bit was never set, even if writeback caching was enabled) * add MODE SENSE r/w error recovery page

* note a nasty problem with shared interrupts that must be fixed before we turn on certain code paths. * add a few comments to the READ CAPACITY scsi simulator * remove a FIXME comment from the TEST UNIT READY scsi simulator * add constant for ATA command CHECK POWER MODE, and associated "mandatory" power management feature set bit.

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.

Since all boards specify base_baud, the code to default base_baud to the architecture-defined BASE_BAUD is redundant. Also, defaulting to the architecture-defined BASE_BAUD is wrong since the UARTs on a serial PCI card will be clocked at the same rate no matter what the architecture of the host machine.

This eliminates the last SWI user from the kernel - now all SWI calls will only come from userspace. More importantly, this also allows us to empty the kernel stack when starting userspace programs from kernelspace, thereby ensuring that the user registers always appear at the top of the kernel stack.

This moves a bunch of EXPORT_SYMBOL() statements from armksyms.c into the file which defines the function/variable such that the exports are localised. This also means we can get rid of the ugly __xxx_to_xxx__is_a_macro in include/asm-arm/arch-*/memory.h

No more users of the autoirq_xxx() API existed, so this file is not only unused, it isn't even listed in any makefiles.

This patch makes the b44-after-bcm4400 scenario work for me. What was happening is that the broadcom driver sets a "power off MAC" bit, and we didn't remove that when initializing the chip. Also added some (a bit ugly, I know ) logic to clear up the address filter stuff, which is what recent broadcom drivers do...

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)

From: Ivan Kokshaysky <ink@jurassic.park.msu.ru> This skips the GP-loading function prologue (two instructions: 8 bytes) on BRSGP linkage correctly, fixing an oops on alpha while loading the aic7xxx driver.

mapped memory. A regular "memset()" may be using cache control instructions etc, which is not appropriate for memory-mapped IO. This also fixes a warning.

Patch from Robin Farine Fix the xscale cache handling routines that were invalidating a D cache line instead of draining the write & fill buffer as intended.

Patch from Catalin Marinas Unlike the v5 architecture, the ARM1136 requires that BIT4 is 0 in the first level page descriptor (ARM1136 TRM, page 6-39). It works at the moment but it might break future v6 cores.

Patch from Catalin Marinas The v6_dma_invalidate_range - the "mcr" instruction for draining the write buffer requires r0 == 0. A "cmp" instruction for testing the end address is missing in the v6_dma_flush_range function.

Patch from Catalin Marinas The _raw_write_(try)lock functions in include/asm-arm/spinlock.h should use the early clobber modifier (&) for the "tmp" register. A newer compiler (gcc-3.4.0) generates an "strexeq %0, %1, [%2]" instruction where %0 is the same as %2, which is illegal.

Patch from Catalin Marinas In the blockops_check() function, cache_type is uninitialised because an "mcr" instruction is used instead of "mrc".

This fixes the problem with recursion into filesystem when inode of quota file needs a page + some other allocation problems. I hope I got the GFP mask setting right..

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.

We need to always allocate at least one indirect block pointer, since we always fill out blocks[0] even if we don't have any groups.

Trivia. CMD640 driver doesn't use generic IDE PCI code (it doesn't even include this header).

- many Maxtor disks incorrectly claim CACHE FLUSH EXT command support, fix it by checking both CACHE FLUSH EXT command and LBA48 support (thanks to Eric D. Mudama for help in fixing this) - write_cache() was called with 'drive->id->cfs_enable_2 & 0x3000' as 'int arg' argument which was always truncated to zero due to 'u8 drive->wcache = arg' assignment so write cache was indeed enabled but drive->wcache was zero (thanks to Rene Herman for help in debugging this) - flush cache in idedisk_start_power_step() only if ATA-6 CACHE FLUSH (EXT) bits are present in disk's identify data (prevents sending unknown commands) - set drive->wcache in idedisk_setup() not idedisk_attach() (no need to check id->command_set_2 - we check id->cfs_enable_2 instead in write_cache() call) - use ide_cacheflush_p() in idedisk_setup() - minor cleanups
