arch/ppc64/lib/locks.c was recently added by Paulus' lock rewrite. It's always compiled, which breaks non-SMP builds. Below patch makes it depend on CONFIG_SMP.

This re-jigs atomic.h by providing atomic_add_return and atomic_sub_return as other architectures do. This allows us to implement the atomic ops that test the new value without having to write the underlying atomic operation in various forms.

Patch from: Ian Campbell This changes the atomic_t in struct page named count into a private member _count which breaks arch/arm/mm/init.c at line 80 which reads page->count directly in show_mem(). The comments in the above changeset suggest that page_count(page) is precisely equal to the old page->count semantics, even though the semantics of _count are different, so I think the following is correct

Doesn't anyone ever actually build the patches they send me...

this makes the core use the new safe waiting helper. - remove wait_ms from hub driver
-
Oliver Neukum authored
this is a new waiting helper safe even if we are left on a waitqueue. This version addresses Alan's concerns about ifdefs. Please apply. - add delay helper that is safe even if we are still on another waitqueue

This resolves a FIXME by adding module parameters that can be used to provide stable (vs random) addresses, and gets rid of a runtime error from obsolete module parameter usage in the RNDIS code. The stable ethernet addresses are nice to hosts, which will normally want to save them away in config databases. For example, without stable addresses Windows XP will end up recording quite a lot of RNDIS devices.

This should fix the problem David Meggy found, where RNDIS was setting the OID_GEN_CURRENT_PACKET_FILTER state incorrectly. It's the same issue Andrew Morton noticed a while back, for that matter, but with more than just a "now compiles on 64 bit" fix. Basically the code needs to interpret 32 bits provided in the request from the (Windows) host, rather than 8 bits of other memory that's got some irrelevant value. The fix is just to save the 32 bits. I did the same thing with the CDC Ethernet filter, which should eventually be used the same way: to limit what packets get sent to the host. Also defined a couple more of the CDC requests.

I made a mistake fixing that driver. Here's the fix. Please apply soon. - fix race condition leading to busy waiting

Here are some MSEC_TO_JIFFIES() fixes missed by whoever did it, plus a minor fix to grab root_hub->serialize() during OHCI suspend. (I forgot to cut/paste those lines from resume.)

drivers/scsi/hosts.h is obsolete, <scsi/scsi_host.h> is the prefered header nowadays. (hosts.h is just a 1 line wrapper to include it for now anyway)

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
