2014-08-16of/irq: Fix lookup to use 'interrupts-extended' property firstFlorian Fainelli1-8/+9
In case the Device Tree blob passed by the boot agent supplies both an 'interrupts-extended' and an 'interrupts' property in order to allow for older kernels to be usable, prefer the new-style 'interrupts-extended' property which conveys a lot more information. This allows us to have bootloaders willingly maintaining backwards compatibility with older kernels without entirely deprecating the 'interrupts' property. Update the bindings documentation to describe a situation where both the 'interrupts-extended' and the 'interrupts' property are present, and which one takes precedence over the other.

2014-08-16of: Allow mem_reserve of memory with a base address of zeroAl Cooper1-1/+1
__reserved_mem_reserve_reg() won't reserve memory if the base address is zero. This change removes the check for a base address of zero and allows it to be reserved. Allowing the first 4K of memory to be reserved will help solve a problem on some ARM systems where the the first 16K of memory is unused and becomes allocable memory. This will prevent this memory from being used for DMA by drivers like the USB OHCI driver which consider a physical address of zero to be illegal.

2014-08-15[SCSI] save command pool address of Scsi_HostJuergen Gross1-2/+10
If a scsi host driver specifies .cmd_len in it's scsi_host_template, a driver's private command pool is needed. scsi_find_host_cmd_pool() will locate it, but scsi_alloc_host_cmd_pool() isn't saving the pool address in the host template. This will result in an access error when the host is removed. Avoid the problem by saving the address of a new allocated command pool where it is expected.

2014-08-15i40e: Fix for recent kernel panicAnjali Singhai Jain1-3/+15
Whenever we get a Tx hang we issue a PFR, which means we send AQ messages to VFS about the reset coming. Unfortunately with the recent fix to be able to send messages to all VFS which earlier was not happening at all we now are sending messages to not just the VFS that are up but also to VFS that are not up. AQ complains about this and sends us an error in ARQ called LAN overflow event for a queue. We check if the queue belongs to a VF and if it does we try to send a vc_notify_vf_reset message to that VF. Well if the VF is not up/enabled we will be entering this function with a non-active VF id. In this function we were assuming VF struct is populated but it won't be if the VF is not active.

git commit 37f81fa1f63ad38e16125526bb2769ae0ea8d332 "n_tty: do O_ONLCR translation as a single write" surfaced a bug in the 3215 device driver. In combination this broke tab expansion for tty ouput. The cause is an asymmetry in the behaviour of tty3215_ops->write vs tty3215_ops->put_char. The put_char function scans for '\t' but the write function does not. As the driver has logic for the '\t' expansion remove XTABS from c_oflag of the initial termios as well.

The khwrngd thread is started when a hwrng device of sufficient quality is registered. The virtio-rng device is backed by the hypervisor, and we trust the hypervisor to provide real entropy. A malicious or badly-implemented hypervisor is a scenario that's irrelevant -- such a setup is bound to cause all sorts of badness, and a compromised hwrng is the least of the user's worries. Given this, we might as well assume that the quality of randomness we receive is perfectly trustworthy. Hence, we use 100% for the factor, indicating maximum confidence in the source.

2014-08-14net: xgene: Check negative return value of xgene_enet_get_ring_size()Tobias Klauser1-2/+5
xgene_enet_get_ring_size() returns a negative value in case of an error, but its only caller in xgene_enet_create_desc_ring() currently uses the return value directly as u32. Instead, check for a negative value first and error out in case. Also move the call to xgene_enet_get_ring_size() before devm_kzalloc() so we don't need to free anything in the error path. This fixes the following issue reported by the Coverity Scanner: ** CID 1231336: Improper use of negative value (NEGATIVE_RETURNS) /drivers/net/ethernet/apm/xgene/xgene_enet_main.c: 596 in xgene_enet_create_desc_ring() Signed-off-by: Tobias Klauser <[email protected]> Signed-off-by: David S.

2014-08-14net: xilinx: Remove .owner field for driverMichal Simek3-3/+0
There is no need to init .owner field. Based on the patch from Peter Griffin <[email protected]> "mmc: remove .owner field for drivers using module_platform_driver" This patch removes the superflous .owner field for drivers which use the module_platform_driver API, as this is overriden in platform_driver_register anyway."
