This was because of a race that existed when doing a read-modify-write sequence on CTL_STATUS. After the read step in this sequence, if an interrupt occurred (causing one of the bits in CTL_STATUS to be set) the write step would inadvertently clear it. Observed with the TMIO_STAT_RXRDY bit together with CMD53 on AR6002 and BCM4318 SDIO cards in polled mode. This patch eliminates this race by only writing to CTL_STATUS and clearing the interrupts that were passed as an argument to ack_mmc_irqs()."

Periodically (1 HZ), that state is synced from one power domain to the other (peripheral->core). When we are resuming, we need to wait for the sync to occur so that we don't get a mismatch of reading undefined state in the rest of the driver. Further, once the externally maintained bits have been synced back into the core, we then need to restore the bits maintained in the core. In our particular case, that is just the write completion interrupt bit. If we don't do any of this, working with the RTC causes ~5 second delays from time to time after waking up due to the write completion interrupt never firing.

The GO_IDLE (CMD0) in mmc_sd_get_cid() causes CSR chips to be reset (this is non-standard behavior). When initializing an SDIO card check for a combo card by using the memory present bit in the R4 response to IO_SEND_OP_COND (CMD5). This avoids the call to mmc_sd_get_cid() on an SDIO-only card.

The cause is that the active node gave up while waiting for an MPA response from the peer and tried to close the connection by sending RST. The passive node driver receives the RST but is waiting for MPA response from the user. When the MPA accept is received, the driver offloads the connection and sends a CLOSE event. The driver gets an AE indicating RESET received and also sends a CLOSE event, hitting a BUG(). Fix this by correcting RESET handling and sending CLOSE events.

In practice, most user applications assume that it is actually defined as the i8253 PIT base clock of 1193182 Hz, which is true on some architectures but not on others. This patch makes the vt code use the PIT frequency on all architectures, which is much more well-defined. It will change the behavior of user applications sending the beep ioctl on all architectures that define CLOCK_TICK_RATE different from PIT_TICK_RATE. The original breakage was introduced in commit bcc8ca099 "Adapt drivers/char/vt_ioctl.c to non-x86". Hopefully, reverting this change will make the frequency correct in more cases than it will make it incorrect.

The data[6] byte contains either 1 or -1 depending on the whether the mouse wheel on older wacom tablets is moved down (1) or up (-1). The patch introduced in the above commit changed the cast from (signed char) to (signed). When cast as a signed integer and negated, the value of -1 (stored in the byte as 0xff) became -255 rather than 1. This patch reverts the cast to a (signed char) and also removes an unnecessary (signed) cast, as all the values operated on are bitmasked.

The crash is caused by accessing already freed task structs. The fix changes the order for registering and unregistering notifier callbacks. All notifiers must be initialized before buffers start working. To stop buffer synchronization we cancel all workqueues, unregister the notifier callback and then flush all buffers. After all of this we finally can free all tasks listed. This should avoid accessing freed tasks.

First, the BIOS may refuse to give control of the PCIe Capability Structure if it is not asked for any of the _OSC features depending on it at the same time. Second, the BIOS may assume that control of the _OSC features depending on the PCIe Capability Structure will be requested in the future and may behave incorrectly if that doesn't happen. For this reason, control of the PCIe Capability Structure should always be requested along with control of any other _OSC features that may depend on it (ie. PCIe native PME, PCIe native hot-plug, PCIe AER). Rework the PCIe port driver so that (1) it checks which native PCIe port services can be enabled, according to the BIOS, and (2) it requests control of all these services simultaneously. In particular, this causes pcie_portdrv_probe() to fail if the BIOS refuses to grant control of the PCIe Capability Structure, which means that no native PCIe port services can be enabled for the PCIe Root Complex the given port belongs to. If that happens, ASPM is disabled to avoid problems with mishandling it by the part of the PCIe hierarchy for which control of the PCIe Capability Structure has not been received. Make it possible to override this behavior using 'pcie_ports=native' (use the PCIe native services regardless of the BIOS response to the control request), or 'pcie_ports=compat' (do not use the PCIe native services at all). Accordingly, rework the existing PCIe port service drivers so that they don't request control of the services directly. Signed-off-by: Rafael J.

To implement it, rework acpi_pci_osc_control_set() so that the caller can specify the mask of _OSC control bits to negotiate and the mask of _OSC control bits that are absolutely necessary to it. Then, acpi_pci_osc_control_set() will run _OSC queries in a loop until the mask of _OSC control bits returned by the BIOS is equal to the mask passed to it. Also, before running the _OSC request acpi_pci_osc_control_set() will check if the caller's required control bits are present in the final mask. Using this mechanism we will be able to avoid situations in which the BIOS doesn't grant control of certain _OSC features, because they depend on some other _OSC features that have not been requested.

However, in general, that need not be the case. For example, if an _OSC feature A depends on an _OSC feature B and control of A, B plus another _OSC feature C is requested simultaneously, the BIOS may return A, B, C, while it would only return C if A and C were requested without B. That may result in passing a wrong mask of _OSC control bits to an _OSC control request, in which case the BIOS may only grant control of a subset of the requested features. Moreover, acpi_pci_run_osc() will return error code if that happens and the caller of acpi_pci_osc_control_set() will not know that it's been granted control of some _OSC features. Consequently, the system will generally not work as expected. Apart from this acpi_pci_osc_control_set() always uses the mask of _OSC control bits returned by the very first invocation of acpi_pci_query_osc(), but that is done with the second argument equal to OSC_PCI_SEGMENT_GROUPS_SUPPORT which generally happens to affect the returned _OSC control bits. For these reasons, make acpi_pci_osc_control_set() always check if control of the requested _OSC features will be granted before making the final control request. As a result, the osc_control_qry and osc_queried members of struct acpi_pci_root are not necessary any more, so drop them and remove the remaining code referring to them. Signed-off-by: Rafael J.

One of the purposes is largely mirrored by MD_CHANGE_PENDING which is not used for anything else, so have MD_CHANGE_PENDING take over that purpose fully. The two purposes are: 1/ tell md_update_sb that an update is needed and that it is just a clean/dirty transition. 2/ tell user-space that an transition from clean to dirty is pending (something wants to write), and tell te kernel (by clearin the flag) that the transition is OK. The first purpose remains wit MD_CHANGE_CLEAN, the second is moved fully to MD_CHANGE_PENDING. This means that various places which conditionally set or cleared MD_CHANGE_CLEAN no longer need to be conditional. Signed-off-by: NeilBrown <neilb@suse.de>

This is no longer necessary since there are more specific locks which the mdio_{read,write}() functions will obtain. Worse, those functions do not save and restore IRQ flags when locking the MII state, so interrupts will be enabled when generic_mii_ioctl() returns. Since there is currently no need for any function to call mdio_{read,write}() while holding another spinlock, do not change them to save and restore IRQ flags but remove the specification of ordering between vortex_private::lock and vortex_private::mii_lock.

What? Don't cross the GRO streams. Why? It would be bad. I'm fuzzy on the whole good/bad thing. What do you mean, "bad"? Try to imagine all the Internet as you know it stopping instantaneously and every bit in every packet swapping at the speed of light. Total packet reordering. Right. That's bad. Okay. All right. Important safety tip. Thanks, Hubert The simplest way to stop this is just avoid doing GRO on the second port. Very few Marvell boards support two ports per ring, and GRO is just an optimization.
