2013-09-19drm/fb-helper: don't sleep for screen unblank when an oops is in progressDaniel Vetter
Otherwise the system will burn even brighter and worse, leave the user wondering what's going on exactly. Since we already have a panic handler which will (try) to restore the entire fbdev console mode, we can just bail out. Inspired by a patch from Konstantin Khlebnikov. The callchain leading to this, cut&pasted from Konstantin's original patch: callstack: panic() bust_spinlocks(1) unblank_screen() vc->vc_sw->con_blank() fbcon_blank() fb_blank() info->fbops->fb_blank() drm_fb_helper_blank() drm_fb_helper_dpms() drm_modeset_lock_all() mutex_lock(&dev->mode_config.mutex) Note that the entire locking in the fb helper around panic/sysrq and kdbg is ... non-existant. So we have a decent change of blowing up everything. But since reworking this ties in with funny concepts like the fbdev notifier chain or the impressive things which happen around console_lock while oopsing, I'll leave that as an exercise for braver souls than me.

2013-09-19ARM: shmobile: change dev_id to cpu0 while registering cpu clockSudeep KarkadaNagesha
Currently all clkdev registration use "cpufreq-cpu0.0" as dev_id for cpu clock which refers to virtual platform device. It needs to be "cpu0" instead which is actual cpu0 device id. This patch changes the dev_id from "cpufreq-cpu0.0" to "cpu0".

2013-09-19cpufreq: imx6q-cpufreq: assign cpu_dev correctly to cpu0 deviceSudeep KarkadaNagesha
Commit cdc58d602d2e657602a90c190cbf745886c95977 "cpufreq: imx6q-cpufreq: remove device tree parsing for cpu nodes" assumed the pdev->dev is set to cpu0 device in the platform code. But it actually points to the virtual cpufreq-cpu0 platform device which is not present in the device tree. Most of the information needed by cpufreq is stored in cpu0 DT node. So cpu_dev must point to cpu0 device. This patch fixes the wrong assignment to cpu_dev.

2013-09-19drm/ttm: fix the tt_populated check in ttm_tt_destroy()Ben Skeggs
After a vmalloc failure in ttm_dma_tt_alloc_page_directory(), ttm_dma_tt_init() will call ttm_tt_destroy() to cleanup, and end up inside the driver's unpopulate() hook when populate() has never yet been called. On nouveau, the first issue to be hit because of this is that dma_address[] may be a NULL pointer. After working around this, ttm_pool_unpopulate() may potentially hit the same issue with the pages[] array. It seems to make more sense to avoid calling unpopulate on already unpopulated TTMs than to add checks to all the implementations.

Such overflow will occur if, for example, the parent clock is set to a 20MHz frequency and the ADC startup time is larger than 215ns. To fix this, introduce an intermediate variable holding the clock rate in kHz.

2013-09-18net:dccp: do not report ICMP redirects to user spaceDuan Jiong
DCCP shouldn't be setting sk_err on redirects as it isn't an error condition. it should be doing exactly what tcp is doing and leaving the error handler without touching the socket. Signed-off-by: Duan Jiong <duanj.fnst@cn.fujitsu.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-09-18cnic: Fix crash in cnic_bnx2x_service_kcq()Michael Chan
commit 104a43edb264321a4d41850e98153b4fa8a9ef42 cnic: Use CHIP_NUM macros from bnx2x.h changed the code to use the bnx2x macro NO_FCOE() to determine if FCoE is supported or not. There is another place in cnic that is still using the old method to determine if FCoE is supported or not. The 2 methods may not yield the same result after the network interface is brought down and up. This will cause the crash as cnic_bnx2x_service_kcq() will access the uninitialized cp->kcq2. The fix is to consistently use the same macro CNIC_SUPPORTS_FCOE() which uses the bnx2x NO_FCOE() macro. As a follow-up, we can clean up the code to remove the old method as it is no longer needed.

2013-09-18RPCSEC_GSS: fix crash on destroying gss authJ. Bruce Fields
This fixes a regression since eb6dc19d8e72ce3a957af5511d20c0db0a8bd007 "RPCSEC_GSS: Share all credential caches on a per-transport basis" which could cause an occasional oops in the nfsd code (see below). The problem was that an auth was left referencing a client that had been freed. To avoid this we need to ensure that auths are shared only between descendants of a common client; the fact that a clone of an rpc_client takes a reference on its parent then ensures that the parent client will last as long as the auth. Also add a comment explaining what I think was the intention of this code. general protection fault: 0000 [#1] PREEMPT SMP Modules linked in: rpcsec_gss_krb5 nfsd auth_rpcgss oid_registry nfs_acl lockd sunrpc CPU: 3 PID: 4071 Comm: kworker/u8:2 Not tainted 3.11.0-rc2-00182-g025145f #1665 Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 Workqueue: nfsd4_callbacks nfsd4_do_callback_rpc [nfsd] task: ffff88003e206080 ti: ffff88003c384000 task.ti: ffff88003c384000 RIP: 0010:[<ffffffffa00001f3>] [<ffffffffa00001f3>] rpc_net_ns+0x53/0x70 [sunrpc] RSP: 0000:ffff88003c385ab8 EFLAGS: 00010246 RAX: 6b6b6b6b6b6b6b6b RBX: ffff88003af9a800 RCX: 0000000000000002 RDX: ffffffffa00001a5 RSI: 0000000000000001 RDI: ffffffff81e284e0 RBP: ffff88003c385ad8 R08: 0000000000000001 R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000015 R12: ffff88003c990840 R13: ffff88003c990878 R14: ffff88003c385ba8 R15: ffff88003e206080 FS: 0000000000000000(0000) GS:ffff88003fd80000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 00007fcdf737e000 CR3: 000000003ad2b000 CR4: 00000000000006e0 Stack: ffffffffa00001a5 0000000000000006 0000000000000006 ffff88003af9a800 ffff88003c385b08 ffffffffa00d52a4 ffff88003c385ba8 ffff88003c751bd8 ffff88003c751bc0 ffff88003e113600 ffff88003c385b18 ffffffffa00d530c Call Trace: [<ffffffffa00001a5>] ? rpc_net_ns+0x5/0x70 [sunrpc] [<ffffffffa00d52a4>] __gss_pipe_release+0x54/0x90 [auth_rpcgss] [<ffffffffa00d530c>] gss_pipe_free+0x2c/0x30 [auth_rpcgss] [<ffffffffa00d678b>] gss_destroy+0x9b/0xf0 [auth_rpcgss] [<ffffffffa000de63>] rpcauth_release+0x23/0x30 [sunrpc] [<ffffffffa0001e81>] rpc_release_client+0x51/0xb0 [sunrpc] [<ffffffffa00020d5>] rpc_shutdown_client+0xe5/0x170 [sunrpc] [<ffffffff81098a14>] ? cpuacct_charge+0xa4/0xb0 [<ffffffff81098975>] ? cpuacct_charge+0x5/0xb0 [<ffffffffa019556f>] nfsd4_process_cb_update.isra.17+0x2f/0x210 [nfsd] [<ffffffff819a4ac0>] ? _raw_spin_unlock_irq+0x30/0x60 [<ffffffff819a4acb>] ? _raw_spin_unlock_irq+0x3b/0x60 [<ffffffff810703ab>] ? process_one_work+0x15b/0x510 [<ffffffffa01957dd>] nfsd4_do_callback_rpc+0x8d/0xa0 [nfsd] [<ffffffff8107041e>] process_one_work+0x1ce/0x510 [<ffffffff810703ab>] ? process_one_work+0x15b/0x510 [<ffffffff810712ab>] worker_thread+0x11b/0x370 [<ffffffff81071190>] ? manage_workers.isra.24+0x2b0/0x2b0 [<ffffffff8107854b>] kthread+0xdb/0xe0 [<ffffffff819a4ac0>] ? _raw_spin_unlock_irq+0x30/0x60 [<ffffffff81078470>] ? __init_kthread_worker+0x70/0x70 [<ffffffff819ac7dc>] ret_from_fork+0x7c/0xb0 [<ffffffff81078470>] ? __init_kthread_worker+0x70/0x70 Code: a5 01 00 a0 31 d2 31 f6 48 c7 c7 e0 84 e2 81 e8 f4 91 0a e1 48 8b 43 60 48 c7 c2 a5 01 00 a0 be 01 00 00 00 48 c7 c7 e0 84 e2 81 <48> 8b 98 10 07 00 00 e8 91 8f 0a e1 e8 +3c 4e 07 e1 48 83 c4 18 RIP [<ffffffffa00001f3>] rpc_net_ns+0x53/0x70 [sunrpc] RSP <ffff88003c385ab8> Signed-off-by: J.

2013-09-18ARM: dts: Fix muxing and regulator for wl12xx on the SDIO bus for blazeTony Lindgren
Commit 76787b3b (ARM: OMAP2+: Remove board-4430sdp.c) removed legacy booting in favor of device tree based booting for 4430sdp. That caused the WLAN to stop working as the related .dts entries fell through the cracks. I don't have the "1283 PG 2.21 connectivity device" on my 4430sdp, but the earlier version of this patch was tested by Luciano Coelho. This version has left out the input logic for MMC CLK line compared to the earlier version as that is not bidirectional, and should be safe to do.

2013-09-18ARM: dts: Fix muxing and regulator for wl12xx on the SDIO bus for pandaboardTony Lindgren
Commit b42b9181 (ARM: OMAP2+: Remove board-omap4panda.c) removed legacy booting in favor of device tree based booting for pandaboard. That caused the WLAN to stop working as the related .dts entries fell through the cracks. The legacy muxing was setting pulls for GPIO 48 and 49, so let's keep that behaviour for now to avoid further regressions for BT and FM. Also input logic was enabled for MMC CLK line, but I've verified that the input logic we don't need enabled for CLK line as it's not bidirectional. Also, we want to use non-removable instead of ti,non-removable as the ti,non-removable also sets no_regulator_off_init which is really not what we want as then wl12xx won't get powered up and down which is needed for resetting it. Note that looks like the WLAN interface fails to come up after a warm reset, but that most likely was also happening with the legacy booting and needs a separate fix.
