From EHCI Spec p.28 HC should clear PORT_SUSPEND when SW clears PORT_RESUME. In Intel Oaktrail platform, MPH (Multi-Port Host Controller) core clears PORT_SUSPEND directly when SW sets PORT_RESUME bit. If we rely on PORT_SUSPEND bit to stop USB resume, we will miss the action of clearing PORT_RESUME. This will cause unexpected long resume signal on USB bus. Signed-off-by:

This patch adds the product ID of Huawei's Vodafone K4605 mobile broadband modem to option.c. This is necessary so that the driver gets loaded on demand without the intervention of usb_modeswitch. This has the benefit of it becoming available faster and also ensures that the option driver is not bound to a network interface that should be claimed by suitable network driver. Signed-off-by:

For a long time, the xHCI driver has had this note: /* FIXME: Ignoring zero-length packets, can those happen? */ It turns out that, yes, there are drivers that need to queue zero-length transfers for isochronous OUT transfers. Without this patch, users will see kernel hang messages when a driver attempts to enqueue an isochronous URB with a zero length transfer (because count_isoc_trbs_needed will return zero for that TD, xhci_td->last_trb will never be set, and updating the dequeue pointer will cause an infinite loop). Matěj ran into this issue when using an NI Audio4DJ USB soundcard with the snd-usb-caiaq driver. See https://bugzilla.kernel.org/show_bug.cgi?id=40702 Fix count_isoc_trbs_needed() to return 1 for zero-length transfers (thanks Alan on the math help). Update the various TRB field calculations to deal with zero-length transfers. We're still transferring one packet with a zero-length data payload, so the total_packet_count should be 1. The Transfer Burst Count (TBC) and Transfer Last Burst Packet Count (TLBPC) fields should be set to zero. This patch should be backported to kernels as old as 2.6.36. Signed-off-by:

Commit db64fe02 ("mm: rewrite vmap layer") introduced code that does address calculations under the assumption that VMAP_BLOCK_SIZE is a power of two. However, this might not be true if CONFIG_NR_CPUS is not set to a power of two. Wrong vmap_block index/offset values could lead to memory corruption. However, this has never been observed in practice (or never been diagnosed correctly); what caught this was the BUG_ON in vb_alloc() that checks for inconsistent vmap_block indices. To fix this, ensure that VMAP_BLOCK_SIZE always is a power of two. BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=31572Reported-by:

Andy Shevchenko authored
Sometimes host->clock could be zero which is a legal situation. This patch checks host->clock before usage as a denominator when timeout is calculated. A similar patch is applied for mmc core (see commit e9b86841, "mmc: fix division by zero in MMC core"). Without this patch, the execution of the sdhci_calc_timeout could end up with a backtrace: <0>[ 4.014319] divide error: 0000 [#1] PREEMPT SMP <4>[ 4.014352] Modules linked in: g_ether <4>[ 4.014376] <4>[ 4.014393] Pid: 33, comm: kworker/u:2 Not tainted 3.0.0+ #646 <4>[ 4.014421] EIP: 0060:[<c12fa38e>] EFLAGS: 00010046 CPU: 1 <4>[ 4.014449] EIP is at sdhci_calc_timeout+0x2e/0x100 <4>[ 4.014468] EAX: 00000000 EBX: f5930fc8 ECX: 00000000 EDX: 00000000 <4>[ 4.014488] ESI: f5291de8 EDI: f5291db8 EBP: f5291c6c ESP: f5291c50 <4>[ 4.014508] DS: 007b ES: 007b FS: 00d8 GS: 0000 SS: 0068 <0>[ 4.014529] Process kworker/u:2 (pid: 33, ti=f5290000 task=f53065a0 task.ti=f5290000) <0>[ 4.014546] Stack: <4>[ 4.014557] 00000082 c1054fdd f5291c78 04000000 f5930fc8 f5291de8 f5291db8 f5291cac <4>[ 4.014611] c12fab7c c107a98b f5291c88 c13b6d3f f593109c f5882000 f5291cac c1054fdd <4>[ 4.014663] 00000000 00000000 f5882000 00000082 f5930fc8 f5291db8 0000000a f5291ccc <0>[ 4.014716] Call Trace: <4>[ 4.014743] [<c1054fdd>] ? mod_timer+0x11d/0x380 <4>[ 4.014770] [<c12fab7c>] sdhci_prepare_data+0x2c/0x3a0 <4>[ 4.014798] [<c107a98b>] ? trace_hardirqs_off+0xb/0x10 <4>[ 4.014827] [<c13b6d3f>] ? _raw_spin_unlock_irqrestore+0x2f/0x60 <4>[ 4.014854] [<c1054fdd>] ? mod_timer+0x11d/0x380 <4>[ 4.014880] [<c12fc7db>] sdhci_send_command+0xdb/0x210 <4>[ 4.014906] [<c12fd5f3>] sdhci_request+0xc3/0x150 <4>[ 4.014932] [<c12ec56a>] mmc_start_request+0xda/0x200 <4>[ 4.014960] [<c120d7c2>] ? __raw_spin_lock_init+0x32/0x60 <4>[ 4.014989] [<c1066a85>] ? __init_waitqueue_head+0x35/0x50 <4>[ 4.015015] [<c12ec70b>] mmc_wait_for_req+0x7b/0x90 <4>[ 4.015045] [<c12f0c67>] mmc_send_cxd_data+0xf7/0x130 <4>[ 4.015076] [<c12ecbc0>] ? mmc_erase+0x140/0x140 <4>[ 4.015102] [<c12f139d>] mmc_send_ext_csd+0x1d/0x20 <4>[ 4.015125] [<c12efef0>] mmc_get_ext_csd+0x70/0x140 <4>[ 4.015151] [<c12effe8>] mmc_compare_ext_csds+0x28/0x190 <4>[ 4.015176] [<c12f039f>] mmc_init_card+0x24f/0x650 <4>[ 4.015201] [<c13b6d5d>] ? _raw_spin_unlock_irqrestore+0x4d/0x60 <4>[ 4.015226] [<c107fd9c>] ? trace_hardirqs_on_caller+0x11c/0x160 <4>[ 4.015255] [<c12f09a4>] mmc_attach_mmc+0xa4/0x190 <4>[ 4.015282] [<c12ee3f0>] mmc_rescan+0x210/0x240 <4>[ 4.015311] [<c105f9b6>] process_one_work+0x176/0x550 <4>[ 4.015336] [<c105f93a>] ? process_one_work+0xfa/0x550 <4>[ 4.015360] [<c12ee1e0>] ? mmc_init_erase+0x140/0x140 <4>[ 4.015385] [<c1061c2a>] worker_thread+0x12a/0x2c0 <4>[ 4.015410] [<c1061b00>] ? manage_workers.clone.18+0x100/0x100 <4>[ 4.015437] [<c1066244>] kthread+0x74/0x80 <4>[ 4.015463] [<c10661d0>] ? __init_kthread_worker+0x60/0x60 <4>[ 4.015490] [<c13b7dfa>] kernel_thread_helper+0x6/0xd <0>[ 4.015507] Code: 57 89 d7 56 53 89 c3 83 ec 10 8b 40 04 8b 72 28 f6 c4 10 89 45 f0 0f 85 91 00 00 00 85 f6 0f 84 c1 00 00 00 8b 4e 04 31 d2 89 c8 <f7> 73 58 ba d3 4d 62 10 89 c1 8b 06 f7 e2 c1 ea 06 01 d1 f7 45 <0>[ 4.015829] EIP: [<c12fa38e>] sdhci_calc_timeout+0x2e/0x100 SS:ESP 0068:f5291c50 Reported-by:
