The scan capability added to cfg80211/nl80211 introduced a dependency on nl80211 by cfg80211. We can thus no longer have just cfg80211 without nl80211. Specifically, cfg80211_scan_done() calls nl80211_send_scan_aborted() or nl80211_send_scan_done(). Now we remove the option for user to select nl80211. It will always be compiled if user selects cfg80211. Signed-off-by:

Don't call ieee80211_sta_find_ibss() directly, like it's done in STA mode, so that the commit() call is more harmless respectively has less site-effects. Signed-off-by:

When there are no free snums, UCC ethernet should gracefully fail, but currently it oopses this way: # ifconfig eth0 up fill_init_enet_entries: Can not get SNUM. ucc_geth_startup: Can not fill p_init_enet_param_shadow. eth0: Cannot configure net device, aborting. Unable to handle kernel paging request for data at address 0x00000190 Faulting instruction address: 0xc0294c88 Oops: Kernel access of bad area, sig: 11 [#1] [...] NIP [c0294c88] mutex_lock+0x0/0x1c LR [c01b6be8] phy_stop+0x20/0x70 Call Trace: [efb25da0] [efb2eb60] 0xefb2eb60 (unreliable) [efb25db0] [c01b2058] ucc_geth_stop+0x2c/0x8c [efb25dd0] [c01b4194] ucc_geth_open+0x48/0x27c [efb25df0] [c020eec0] dev_open+0xc0/0x118 [...] This is because the ucc_geth_stop() routine assumes that ugeth->phydev is always initialized by the ucc_geth_open(), while it is not in case of errors. If we add a check to the ucc_geth_stop(), then another oops pops up: Unable to handle kernel paging request for data at address 0x00000004 Faulting instruction address: 0xc01b46a4 Oops: Kernel access of bad area, sig: 11 [#1] [...] NIP [c01b46a4] adjust_link+0x20/0x1b4 LR [c01b770c] phy_state_machine+0xdc/0x44c Call Trace: [ef83bf10] [c021b388] linkwatch_schedule_work+0x74/0xf8 (unreliable) [ef83bf40] [c01b770c] phy_state_machine+0xdc/0x44c [ef83bf60] [c004c13c] run_workqueue+0xb8/0x148 [ef83bf90] [c004c870] worker_thread+0x70/0xd0 [ef83bfd0] [c00505fc] kthread+0x48/0x84 [ef83bff0] [c000f464] kernel_thread+0x4c/0x68 [...] That one happens because ucc_geth_stop() does not call phy_disconnect() and so phylib state machine is running without any idea that a MAC has just died. Also, when device tree specifies fixed-link, and CONFIG_FIXED_PHY is disabled, we'll get this oops: 0:01 not found eth2: Could not attach to PHY eth2: Cannot initialize PHY, aborting. Unable to handle kernel paging request for data at address 0x00000190 Faulting instruction address: 0xc02967d0 Oops: Kernel access of bad area, sig: 11 [#1] [...] NIP [c02967d0] mutex_lock+0x0/0x1c LR [c01b6bcc] phy_stop+0x20/0x70 Call Trace: [ef82be50] [efb6bb60] 0xefb6bb60 (unreliable) [ef82be60] [c01b2058] ucc_geth_stop+0x2c/0x8c [ef82be80] [c01b4194] ucc_geth_open+0x48/0x27c [ef82bea0] [c0210a04] dev_open+0xc0/0x118 [ef82bec0] [c020f85c] dev_change_flags+0x84/0x1ac [ef82bee0] [c037b768] ic_open_devs+0x168/0x2bc [ef82bf20] [c037ca98] ip_auto_config+0x90/0x28c [ef82bf60] [c0001b9c] do_one_initcall+0x34/0x1a0 [ef82bfd0] [c035e240] do_initcalls+0x38/0x58 [ef82bfe0] [c035e2c4] kernel_init+0x30/0x90 [ef82bff0] [c000f464] kernel_thread+0x4c/0x68 [...] And again, ucc_geth_stop() assumes that ugeth->phydev is there, while it isn't. This patch fixes all three oopses simply by rearranging some code: - In ucc_geth_open(): move init_phy() call to the beginning, so that we only call ucc_geth_stop() with a PHY attached; - Move phy_disconnect() call from ucc_geth_close() to ucc_geth_stop(), so that we'll always disconnect the PHY.

The inline function skb_gro_mac_header defined in include/linux/netdevice.h makes use of page_address(). Depending on configuration options, the latter is either defined as a macro or is declared as a function in another header file, namely include/linux/mm.h. However, include/linux/netdevice.h does not include include/linux/mm.h. On MIPS, this has produced the following build error: CC kernel/sysctl_check.o In file included from include/linux/icmpv6.h:173, from include/linux/ipv6.h:208, from include/net/ip_vs.h:26, from kernel/sysctl_check.c:6: include/linux/netdevice.h: In function 'skb_gro_mac_header': include/linux/netdevice.h:1132: error: implicit declaration of function 'page_address' include/linux/netdevice.h:1133: warning: pointer/integer type mismatch in conditional expression make[1]: *** [kernel/sysctl_check.o] Error 1 make: *** [kernel] Error 2 The patch adds the missing include and fixes the build error.

DMA mapping can be expensive in the presence of iommus. Reduce the Rx iommu activity by mapping an entire page, and provide the H/W the mapped address + offset of the current page chunk. Reserve bits at the end of the page to track mapping references, so the page can be unmapped. Signed-off-by:
