Do the full chip reset when changing MAC address if ASF is enabled. ASF sometimes uses a different MAC address than the driver. Without the reset, the ASF MAC address may be overwritten when the driver's MAC address is changed. Signed-off-by:

Add netif_carrier_off() call during tg3_phy_reset(). This is needed to properly track the netif_carrier state in cases where we do a PHY reset with interrupts disabled. The SerDes code will not run properly if the netif_carrier state is wrong. Signed-off-by:

We eliminated rt6_dflt_lock (to protect default router pointer) at 2.6.17-rc1, and introduced rt6_select() for general router selection. The function is called in the context of rt6_lock read-lock held, but this means, we have some race conditions when we do round-robin.

I was looking through the xfrm input/output code in order to abstract out the address family specific encapsulation/decapsulation code. During that process I found this bug in the IP ID selection code in xfrm4_output.c. At that point dst is still the xfrm_dst for the current SA which represents an internal flow as far as the IPsec tunnel is concerned. Since the IP ID is going to sit on the outside of the encapsulated packet, we obviously want the external flow which is just dst->child. Signed-off-by:

This patch disables and saves local interrupts during hash_page processing for SPE contexts. We have to do it explicitly in the spu_irq_class_1_bottom function. For the interrupt handlers, we get the behaviour implicitly by using SA_INTERRUPT to disable interrupts while in the handler. Signed-off-by:

As reported in Bugzilla Bug 6406, resume from S3 results in a blank screen. For the IBM Thinkpad X30 using vesafb as the console driver, successful resume from S3 requires option acpi_sleep=s3_bios,s3_mode. Update documentation. I would presume that, in any hardware, using vesafb as the console driver will require as a minimum s3_mode. Signed-off-by:

Generate new sysfs-attribute 'uid' that contains an device specific unique identifier. This can be used to identity multiple ALIASES of the same physical device (PAV). In addition the sysfs-attributes 'vendor' (containing the manufacturer of the device) and 'alias' (identify alias or base device) is added. This is first part of PAV support in LPAR (also valid on zVM). Signed-off-by:

In case of an instruction processing damage (IPD) machine check in kernel mode the resulting action is always to stop the kernel. This is not necessarily the best solution since a retry of the failing instruction might succeed.

With CONFIG_SLAB_DEBUG=y networking over qeth doesn't work. The problem is that the qib structure embedded in the qeth_irq structure needs an alignment of 256 but kmalloc only guarantees an alignment of 8. When using SLAB debugging the alignment of qeth_irq is not sufficient for the embedded qib structure which causes all users of qdio (qeth and zfcp) to stop working. Allocate qeth_irq structure with __get_free_page. That wastes a small amount of memory (~2500 bytes) per online adapter. Signed-off-by:

The dasd state machine is not designed to enable an unformatted device, since 'unformatted' is a final state. The BIODASDENABLE ioctl calls dasd_enable_device() which never returns if the device is in this special state. Return -EPERM in dasd_increase_state for unformatted devices to make dasd_enable_device terminate. Note: To get such an unformatted device online it has to be re-analyzed. This means that the device needs to be disabled prior to re-enablement. Signed-off-by:

Avoid memory allocation with GFP_KERNEL in qdio_establish/qdio_shutdown. Use memory pool instead. (Otherwise this can lead to an I/O stall where qdio waits for a free page and zfcp waits for end of error recovery in low memory situations.) Signed-off-by:

If a signal handler has been established with the SA_ONSTACK option but no alternate stack is provided with sigaltstack(), the kernel still tries to install the alternate stack. Also when setting an alternate stack with sigalstack() and the SS_DISABLE flag, the kernel tries to install the alternate stack on signal delivery. Use the correct conditions sas_ss_flags() to check if the alternate stack has to be used. Signed-off-by:

Running abnormal VM splits causes weird problems - people can set non-standard splits by accident, then lots of time gets wasted diagnosing it - see the long "[stable] 2.6.16.6 breaks java... sort of" email thread. So we need to make this option harder to set. Use CONFIG_EMBEDDED for this. CONFIG_EMBEDDED isn't really the right thing to use, but there's nothing else obvious and avoiding these problems is more important than Kconfig purity. Signed-off-by:
