2008-07-10firmware: Add CONFIG_FIRMWARE_IN_KERNEL option.David Woodhouse
This will control whether we build firmware into the kernel image for _every_ driver which we convert to request_firmware(), to avoid a proliferation of 'CONFIG_XXX_FIRMWARE' options for each one. Default to 'y' for now, which is the wrong thing to do but people seem to be insisting on it and refusing to even review patches until it's done. And it does preserve the existing behaviour for built-in drivers. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2008-07-10firmware: Add CONFIG_EXTRA_FIRMWARE optionDavid Woodhouse
This allows arbitrary firmware files to be included in the static kernel where the firmware loader can find them without requiring userspace to be alive. (Updated and CONFIG_EXTRA_FIRMWARE_DIR added with lots of help from Johannes Berg). Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Johannes Berg <johannes@sipsolutions.net>
2008-07-10firmware: allow firmware files to be built into kernel imageDavid Woodhouse
Some drivers have their own hacks to bypass the kernel's firmware loader and build their firmware into the kernel; this renders those unnecessary. Other drivers don't use the firmware loader at all, because they always want the firmware to be available. This allows them to start using the firmware loader. A third set of drivers already use the firmware loader, but can't be used without help from userspace, which sometimes requires an initrd. This allows them to work in a static kernel.

2008-07-10firmware: make fw->data constDavid Woodhouse
In preparation for supporting firmware files linked into the static kernel, make fw->data const to ensure that users aren't modifying it (so that we can pass a pointer to the original in-kernel copy, rather than having to copy it). Signed-off-by: David Woodhouse <dwmw2@infradead.org>

2008-07-08RDMA/cxgb3: Fix regression caused by class_device -> device conversionSteve Wise
The change to iwch_provider.c in commit f4e91eb4 ("IB: convert struct class_device to struct device") undid the fix done in commit 7f049f2f ("RDMA/cxgb3: Hold rtnl_lock() around ethtool get_drvinfo call"). It removed the calls to rtnl_lock() that serialized the iw_cxgb3 ethtool ops calls into the cxgb3 driver. This locking is needed to avoid messing up the internal state of the cxgb3 driver.

2008-07-08palm_bk3710: fix IDECLK period calculationSergei Shtylyov
The driver uses completely bogus rounding formula for calculating period from the IDECLK frequency which gives one-off period values (e.g. 11 ns with 100 MHz IDECLK) which in turn can lead to overclocked IDE transfer timings. Actually, rounding is just wrong in this case, so use a mere division for a safe result. While at it, also: - give 'ide_palm_clk' variable a more suitable name; - get rid of the useless 'ideclkp' variable; - drop the LISP stype 'p' postfix from the 'clkp' variable's name. :-) Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Cc: mcherkashin@ru.mvista.com Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-07-08ide: add __ide_default_irq() inline helperBartlomiej Zolnierkiewicz
Add __ide_default_irq() inline helper and use it instead of ide_default_irq() in ide-probe.c and ns87415.c (all host drivers except IDE PCI ones always setup hwif->irq so it is enough to check only for I/O bases 0x1f0 and 0x170). This fixes post-2.6.25 regression since ide_default_irq() define could shadow ide_default_irq() inline. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-07-06pxamci: fix byte aligned DMA transfersPhilipp Zabel
The pxa27x DMA controller defaults to 64-bit alignment. This caused the SCR reads to fail (and, depending on card type, error out) when card->raw_scr was not aligned on a 8-byte boundary. For performance reasons all scatter-gather addresses passed to pxamci_request should be aligned on 8-byte boundaries, but if this can't be guaranteed, byte aligned DMA transfers in the have to be enabled in the controller to get correct behaviour.

2008-07-06Revert "USB: don't explicitly reenable root-hub status interrupts"Linus Torvalds
This reverts commit e872154921a6b5256a3c412dd69158ac0b135176. Andrey Borzenkov reports that it resulted in a totally hung machine for him when loading the OHCI driver. Extensive netconsole capture with SysRq output shows that modprobe gets stuck in ohci_hub_status_data() when probing and enabling the OHCI controller, see for example http://lkml.org/lkml/2008/7/5/236 for an analysis. The problem appears to be an interrupt flood triggered by the commit that gets reverted, and Andrey confirmed that the revert makes things work for him again.

Commit ea0c62f7cf70f13a67830471b613337bd0c9a62e tried to clear all bits in irq_stat but it didn't actually achieve that as irq_stat was anded with port_map right after read.

2008-07-05x86 ACPI: normalize segment descriptor register on resumeH. Peter Anvin
Some Dell laptops enter resume with apparent garbage in the segment descriptor registers (almost certainly the result of a botched transition from protected to real mode.) The only way to clean that up is to enter protected mode ourselves and clean out the descriptor registers. This fixes resume on Dell XPS M1210 and Dell D620.

2008-07-04olpc: sdhci: add quirk for the Marvell CaFe's interrupt timeoutAndres Salomon
The CaFe chip has a hardware bug that ends up with us getting a timeout value that's too small, causing the following sorts of problems: [ 60.525138] mmcblk0: error -110 transferring data [ 60.531477] end_request: I/O error, dev mmcblk0, sector 1484353 [ 60.533371] Buffer I/O error on device mmcblk0p2, logical block 181632 [ 60.533371] lost page write due to I/O error on mmcblk0p2 Presumably this is an off-by-one error in the hardware. Incrementing the timeout count value that we stuff into the TIMEOUT_CONTROL register gets us a value that works. This bug was originally discovered by Pierre Ossman, I believe.

This has been sitting around unloved for way too long.. The Marvell CaFe chip's SD implementation chokes during card insertion if one attempts to set the voltage and power up in the same SDHCI_POWER_CONTROL register write.
