From: Linus Torvalds Date: Tue, 8 May 2007 18:57:17 +0000 (-0700) Subject: Merge branch 'upstream-linus' of master.kernel.org:/pub/scm/linux/kernel/git/jgarzik... X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9028780a3e6d2c3dd940e89b377765cca008b6df;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git Merge branch 'upstream-linus' of /linux/kernel/git/jgarzik/netdev-2.6 * 'upstream-linus' of master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/netdev-2.6: (40 commits) [netdrvr] atl1: fix build pasemi_mac: Use local-mac-address instead of mac-address if available pasemi_mac: PHY support pasemi_mac: Add msglevel support and "debug" module param pasemi_mac: Logic cleanup / rx performance improvements pasemi_mac: Minor cleanup / define fixes pasemi_mac: Add SKB reuse / copy-break pasemi_mac: Timer and interrupt fixes pasemi_mac: Abstract and fix up interrupt restart routines pasemi_mac: Move the IRQ mapping from the PCI layer to the driver tc35815: Remove unnecessary skb->dev assignment drivers/net/dm9000: Convert to generic boolean AT91RM9200 Ethernet: Fix multicast addressing AT91RM9200 Ethernet: Support additional PHYs PCMCIA-NETDEV : xirc2ps_cs: bugfix of multicast code sky2: re-enable 88E8056 for most motherboards MIPS: Drop unnecessary CONFIG_ISA from RBTX49XX ne: MIPS: Use platform_driver for ne on RBTX49XX ne: Add NEEDS_PORTLIST to control ISA auto-probe ne: Misc fixes for platform driver. ... Fix conflict in drivers/net/pasemi_mac.c (get_property() got renamed to of_get_property()) manually.
