2008-05-20x86: strengthen 64-bit p?d_bad()Hugh Dickins
The x86_64 pgd_bad(), pud_bad(), pmd_bad() inlines have differed from their x86_32 counterparts in a couple of ways: they've been unnecessarily weak (e.g. letting 0 or 1 count as good), and were typed as unsigned long. Strengthen them and return int. The PAE pmd_bad was too weak before, allowing any junk in the upper half; but got strengthened by the patch correcting its ~PAGE_MASK to ~PTE_MASK. The PAE pud_bad already said ~PTE_MASK; and since it folds into pgd_bad, and we don't set the protection bits at that level, it'll do as is.

2008-05-20x86: define PTE_MASK in a universally useful wayJeremy Fitzhardinge
Define PTE_MASK so that it contains a meaningful value for all x86 pagetable configurations. Previously it was defined as a "long" which means that it was too short to cover a 32-bit PAE pte entry. It is now defined as a pteval_t, which is an integer type long enough to contain a full pte (or pmd, pud, pgd). This fixes an Xorg crash on 32-bit x86 with PAE due to corruption of the NX bit in mprotect due to the incorrect type/value of PTE_MASK reported by Hugh Dickins: "Yes, thanks Jeremy: I've checked that each stage builds and runs X on my boxes here, x86_32 and x86_32+PAE and x86_64. (So even 1/8 is enough to fix the PAT pte_modify issue, though 2/8 then fixes compiler warnings.)"

2008-05-20HID: split Numlock emulation quirk from HID_QUIRK_APPLE_HAS_FN.Diego 'Flameeyes' Petteno
Since 2.6.25 the HID_QUIRK_APPLE_HAS_FN quirk is enabled even for non-laptop Apple keyboards of the Aluminium series. The USB version of these don't need Numlock emulation, like the laptop (and Aluminium Wireless) do, as they have a proper keypad. This patch splits the Numlock emulation for Apple keyboards in a different quirk flag, so that it can be enabled for all the keyboards but the Aluminium USB ones. If the Numlock emulation is enabled for Aluminium USB keyboards, the JKL and UIO keys become the numeric pad, and the rest of the keyboard is disabled, included the key used to disable Numlock. Additionally, these keyboard should not have a Numlock at all, as the Numlock key is instead replaced by the 'Clear' key as usual for Apple USB keyboards.

2008-05-19Fixups to ATA ACPI hotplugMatthew Garrett
The libata-acpi.c code currently accepts hotplug messages from both the port and the device. This does not match the behaviour of the bay driver, and may result in confusion when two hotplug requests are received for the same device. This patch limits the hotplug notification to removable ACPI devices, which in turn allows it to use the _STA method to determine whether the device has been removed or inserted. On removal, devices are marked as detached. On insertion, a hotplug scan is started. This should avoid lockups caused by the ata layer attempting to scan devices which have been removed. The uevent sending is moved outside the spinlock in order to avoid a warning generated by it firing when interrupts are disabled.

I was hoping ATA_HORKAGE_NODMA | ATA_HORKAGE_SKIP_PM could keep it happy but no even this doesn't work under certain configurations and it's not like we can do anything useful with the cofig device anyway.

2008-05-19sata_sil24: don't use NCQ if marvell 4140 PMP is attachedTejun Heo
When 4140 PMP is attached to sil24, NCQ commands to fan out port 1 and 2 (0 based) often stall if commands are in progress to other ports. I've tried a number of things but can't tell what's going on. It never happens w/ ahci and reportedly sata_mv which can issue NCQ commands to multiple devices simultaneously like sil24 does. Disable NCQ for devices behind 4140 PMP for the time being. Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Mark Lord <liml@rtr.ca> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-05-19libata: make sure PMP notification is turned off during recoveryTejun Heo
PMP notification during reset can make some controllers fail reset processing and needs to be turned off during resets. PMP attach and full-revalidation path did this via sata_pmp_configure() but the quick revalidation wasn't. Move the notification disable code right above fan-out port recovery so that it's always turned off. This fixes obscure reset failures.

2008-05-19libata: increase PMP register access timeout to 3sTejun Heo
This timeout was set low because previously PMP register access was done via polling and register access timeouts could stack up. This is no longer the case. One timeout will make all following accesses fail immediately. In rare cases both marvell and SIMG PMPs need almost a second. Bump it to 3s. While at it, rename it to SATA_PMP_RW_TIMEOUT. It's not specific to SCR access. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-05-19libata: ignore recovered PHY errorsTejun Heo
No reason to get overzealous about recovered comm and data errors. Some PHYs habitually sets them w/o no good reason and being draconian about these soft error conditions doesn't seem to help anybody. If need ever rises, we might need to add soft PHY error condition, say AC_ERR_MAYBE_ATA_BUS and use it only to determine whether speed down is necessary but I don't think that's very likely to happen. It's far more likely we'll get timeouts or fatal transmission errors if recovered errors are so prominent that they hamper operation.

2008-05-19libata: kill hotplug related race conditionTejun Heo
Originally, whole reset processing was done while the port is frozen and SError was cleared during @postreset(). This had two race conditions. 1: hotplug could occur after reset but before SError is cleared and libata won't know about it. 2: hotplug could occur after all the reset is complete but before the port is thawed. As all events are cleared on thaw, the hotplug event would be lost. Commit ac371987a81c61c2efbd6931245cdcaf43baad89 kills the first race by clearing SError during link resume but before link onlineness test. However, this doesn't fix race #2 and in some cases clearing SError after SRST is a good idea. This patch solves this problem by cross checking link onlineness with classification result after SError is cleared and port is thawed. Reset is retried if link is online but all devices attached to the link are unknown. As all devices will be revalidated, this one-way check is enough to ensure that all devices are detected and revalidated reliably. This, luckily, also fixes the cases where host controller returns bogus status while harddrive is spinning up after hotplug making classification run before the device sends the first FIS and thus causes misdetection. Low level drivers can bypass the logic by setting class explicitly to ATA_DEV_NONE if ever necessary (currently none requires this).

2008-05-19libata: move reset freeze/thaw handling into ata_eh_reset()Tejun Heo
Previously reset freeze/thaw handling lived outside of ata_eh_reset() mainly because the original PMP reset code needed the port frozen while resetting all the fan-out ports, which is no longer the case. This patch moves freeze/thaw handling into ata_eh_reset(). @prereset() and @postreset() are now called w/o freezing the port although @prereset() an be called frozen if the port is frozen prior to entering ata_eh_reset(). This makes code simpler and will help removing hotplug event related races. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-05-19libata: reorganize ata_eh_reset() no reset method pathTejun Heo

2008-05-19sata_promise: mmio access cleanupsMikael Pettersson
This patch cleans up sata_promise's mmio accesses. In sata_promise there are three distinct mmio address spaces: 1. global registers, offsets from host->iomap[PDC_MMIO_BAR] 2. per-port ATA registers, offsets from ap->ioaddr.cmd_addr 3. per-port SATA registers, offsets from ap->ioaddr.scr_addr The driver currently often fails to indicate which address space a given mmio base pointer refers to, which is a source of bugs and confusion (see recent pdc_thaw() irq clearing bug; it's also been an obstacle for the pending NCQ extensions). To reduce these problems, adopt a coding style where the name of a base pointer always indicates which address space it refers to: 1. global registers: host_mmio 2. per-port ATA registers: ata_mmio 3. per-port SATA registers: sata_mmio Also rearrange register offset definitions to clearly indicate which address space they belong to, and add a symbolic definition for the previously hard-coded PHYMODE4 register.

2008-05-19sata_promise: fix irq clearing bugletsMikael Pettersson
This patch fixes two bugs in sata_promise's irq status clearing paths: 1. When clearing the irq status for a specific port, the driver read the global SEQMASK register. This is wrong because that clears the irq status for _all_ ports. 2. pdc_thaw() incorrectly added the PDC_INT_SEQMASK host register offset to a per-port ata engine base address. This resulted in it reading the unrelated PDC_PKT_SUBMIT register, which did not have the desired irq status clearing effect. In both cases the fix is to read from the port's Command/Status register. This also matches what Promise's own driver does. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
