2010-10-25[S390] set ARCH_HAS_SG_CHAIN for s390Christof Schmitt1-0/+2
Set ARCH_HAS_SG_CHAIN for scatter lists on s390. Without this flag the SCSI code limits the maximum number of segments, so set it to make proper use of the FCP channel hardware. Signed-off-by: Christof Schmitt <christof.schmitt@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2010-10-25[S390] dasd: let recovery cqr inherit flags from failed cqrStefan Weinhuber1-0/+3
The usual way to recover a failed DASD ECKD request (cqr) is to create a new request with an appropriate recovery CCW program. Certain features, e.g. failfast, can be enabled per request and are stored in the requests flags. These flags have to be copied from the failed to the recovery request, to let the recovery request use the same features as the original one.

2010-10-25[S390] zero page cache synonymsMartin Schwidefsky2-7/+64
If the zero page is mapped to virtual user space addresses that differ only in bit 2^12 or 2^13 we get L1 cache synonyms which can affect performance. Follow the mips model and use multiple zero pages to avoid the synonyms. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2010-10-25uwb: Remove the WLP subsystem and driversDavid Vrabel22-8551/+1
The only Wimedia LLC Protocol (WLP) hardware was an Intel i1480 chip with a beta release of firmware that was never commercially available as a product. This hardware and firmware is no longer available as Intel sold their UWB/WLP IP. I also see little prospect of other WLP capable hardware ever being available.

The sticky PCM stream assignment introduced in 2.6.36 kernel seems causing problems on AD codecs. At some time later, the streaming no longer works by unknown reason.

2010-10-25Revalidate caches on lockRicardo Labiaga5-4/+22
Instead of blindly zapping the caches, attempt to revalidate them if the server has indicated that it uses high resolution timestamps. NFSv4 should be able to always revalidate the cache since the protocol requires the update of the change attribute on modification of the data. In reality, there are servers (the Linux NFS server for example) that do not obey this requirement and use ctime as the basis for change attribute. Long term, the server needs to be fixed. At this time, and to be on the safe side, continue zapping caches if the server indicates that it does not have a high resolution timestamp.

2010-10-24i2c-amd8111: Add proper error handlingJulia Lawall1-50/+113
The functions the functions amd_ec_wait_write and amd_ec_wait_read have an unsigned return type, but return a negative constant to indicate an error condition. A sematic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @exists@ identifier f; constant C; @@ unsigned f(...) { <+... * return -C; ...+> } // </smpl> Fixing amd_ec_wait_write and amd_ec_wait_read leads to the need to adjust the return type of the functions amd_ec_write and amd_ec_read, which are the only functions that call amd_ec_wait_write and amd_ec_wait_read. amd_ec_write and amd_ec_read, in turn, are only called from within the function amd8111_access, which already returns a signed typed value. Each of the calls to amd_ec_write and amd_ec_read are updated using the following semantic patch: // <smpl> @@ @@ + status = amd_ec_write - amd_ec_write (...); + if (status) return status; @@ @@ + status = amd_ec_read - amd_ec_read (...); + if (status) return status; // </smpl> The patch also adds the declaration of the status variable.

2010-10-24i2c: Remove unneeded inclusions of <linux/i2c-id.h>Jean Delvare10-10/+0
These drivers don't use anything which is defined in <linux/i2c-id.h>. This header file was never meant to be included directly anyway, and will be deleted soon.

2010-10-24i2c: Let i2c_parent_is_i2c_adapter return the parent adapterJean Delvare3-22/+32
This makes the calling site's code clearer IMHO. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Michael Lawnick <ml.lawnick@gmx.de>
2010-10-24i2c: Simplify i2c_parent_is_i2c_adapterJean Delvare1-1/+0
Only i2c devices can have their type set to i2c_adapter_type, so testing the bus type is redundant. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Michael Lawnick <ml.lawnick@gmx.de>
2010-10-24i2c-pca-platform: Change device name of request_irqNobuhiro Iwamatsu1-1/+1
i2c->adap.name shouldn't be used in request_irq. Instead the driver name "i2c-pca-platform" should be used. Signed-off-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com> Acked-by: Wolfram Sang <w.sang@pengutronix.de> Cc: stable@kernel.org Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-10-24i2c: Fix Kconfig dependenciesJean Delvare2-1/+14
drivers/i2c/algos/Kconfig makes all the algorithms dependent on !I2C_HELPER_AUTO, which triggers a Kconfig warning about broken dependencies when some driver selects one of the algorithms. Ideally we would make only the prompts dependent on !I2C_HELPER_AUTO, however Kconfig doesn't currently support that. So we have to redefine the symbols separately for the I2C_HELPER_AUTO=y case.

2010-10-24ALSA: usb - Creative USB X-Fi volume knob supportMandar Joshi1-0/+1
Adds an entry for Creative USB X-Fi to the rc_config array in mixer_quirks.c to allow use of volume knob on the device. The action of the volume knob is received by lirc when its using the alsa_usb driver. Signed-off-by: Mandar Joshi <emailmandar@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2010-10-24KVM: Drop CONFIG_DMAR dependency around kvm_iommu_map_pagesJan Kiszka1-2/+0
We also have to call kvm_iommu_map_pages for CONFIG_AMD_IOMMU. So drop the dependency on Intel IOMMU, kvm_iommu_map_pages will be a nop anyway if CONFIG_IOMMU_API is not defined. KVM-Stable-Tag. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
