2009-03-25sched: Refactor the power savings balance codeGautham R Shenoy
Impact: cleanup Create seperate helper functions to initialize the power-savings-balance related variables, to update them and to check if we have a scope for performing power-savings balance. Add no-op inline functions for the !(CONFIG_SCHED_MC || CONFIG_SCHED_SMT) case. This will eliminate all the #ifdef jungle in find_busiest_group() and the other helper functions.

2009-03-25sched: Optimize the !power_savings_balance during fbg()Gautham R Shenoy
Impact: cleanup, micro-optimization We don't need to perform power_savings balance if either the cpu is NOT_IDLE or if the sched_domain doesn't contain the SD_POWERSAVINGS_BALANCE flag set. Currently, we check for these conditions multiple number of times, even though these variables don't change over the scope of find_busiest_group(). Check once, and store the value in the already exiting "power_savings_balance" variable.

2009-03-25sched: Create a helper function to calculate imbalanceGautham R Shenoy
Move all the imbalance calculation out of find_busiest_group() through this helper function. With this change, the structure of find_busiest_group() will be as follows: - update_sched_domain_statistics. - check if imbalance exits. - update imbalance and return busiest.

2009-03-25sched: Create helper to calculate small_imbalance in fbg()Gautham R Shenoy

2009-03-25sched: Define structure to store the sched_domain statistics for fbg()Gautham R Shenoy
Impact: cleanup Currently we use a lot of local variables in find_busiest_group() to capture the various statistics related to the sched_domain. Group them together into a single data structure.

2009-03-25[PATCH 13/13] drivers/watchdog: use USB API functions rather than constantsJulia Lawall
This set of patches introduces calls to the following set of functions: usb_endpoint_dir_in(epd) usb_endpoint_dir_out(epd) usb_endpoint_is_bulk_in(epd) usb_endpoint_is_bulk_out(epd) usb_endpoint_is_int_in(epd) usb_endpoint_is_int_out(epd) usb_endpoint_num(epd) usb_endpoint_type(epd) usb_endpoint_xfer_bulk(epd) usb_endpoint_xfer_control(epd) usb_endpoint_xfer_int(epd) usb_endpoint_xfer_isoc(epd) In some cases, introducing one of these functions is not possible, and it just replaces an explicit integer value by one of the following constants: USB_ENDPOINT_XFER_BULK USB_ENDPOINT_XFER_CONTROL USB_ENDPOINT_XFER_INT USB_ENDPOINT_XFER_ISOC An extract of the semantic patch that makes these changes is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r1@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\)) == - \(USB_ENDPOINT_XFER_CONTROL\|0\)) + usb_endpoint_xfer_control(epd) @r5@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bEndpointAddress & \(USB_ENDPOINT_DIR_MASK\|0x80\)) == - \(USB_DIR_IN\|0x80\)) + usb_endpoint_dir_in(epd) @inc@ @@ #include <linux/usb.h> @depends on !inc && (r1||r5)@ @@ + #include <linux/usb.h> #include <linux/usb/...> // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

2009-03-24RDMA/cxgb3: Enforce required firmwareSteve Wise
The cxgb3 NIC driver can handle more firmware versions than iw_cxgb3, and since commit 8207befa ("cxgb3: untie strict FW matching") cxgb3 will load with firmware versions that iw_cxgb3 can't handle. The FW major number indicates a specific interface between the FW and iw_cxgb3. Thus if the major number of the running firmware does not match the required version compiled into iw_cxgb3, then iw_cxgb3 must not register that device.

2009-03-24ipv6: Fix conflict resolutions during ipv6 bindingVlad Yasevich
The ipv6 version of bind_conflict code calls ipv6_rcv_saddr_equal() which at times wrongly identified intersections between addresses.

2009-03-24ipv6: Make v4-mapped bindings consistent with IPv4Vlad Yasevich
Binding to a v4-mapped address on an AF_INET6 socket should produce the same result as binding to an IPv4 address on AF_INET socket. The two are interchangable as v4-mapped address is really a portability aid. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-24ipv6: Allow ipv4 wildcard binds after ipv6 address bindsVlad Yasevich
The IPv4 wildcard (0.0.0.0) address does not intersect in any way with explicit IPv6 addresses. These two should be permitted, but the IPv4 conflict code checks the ipv6only bit as part of the test. Since binding to an explicit IPv6 address restricts the socket to only that IPv6 address, the side-effect is that the socket behaves as v6-only. By explicitely setting ipv6only in this case, allows the 2 binds to succeed. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-24ipv6: Disallow binding to v4-mapped address on v6-only socket.Vlad Yasevich
