2013-01-22USB: EHCI: Move definition of EHCI_STATS to ehci.hRoger Quadros
Without this, platform drivers e.g. ehci-omap.c will see a different version of struct ehci_hcd than ehci-hcd.c and break reference to 'debug_dir' and 'priv' members when CONFIG_USB_DEBUG is enabled.

2013-01-22USB: UHCI: fix IRQ race during initializationAlan Stern
This patch (as1644) fixes a race that occurs during startup in uhci-hcd. If the IRQ line is shared with other devices, it's possible for the handler routine to be called before the data structures are fully initialized. The problem is fixed by adding a check to the IRQ handler routine. If the initialization hasn't finished yet, the routine will return immediately.

2013-01-22ptrace: introduce signal_wake_up_state() and ptrace_signal_wake_up()Oleg Nesterov
Cleanup and preparation for the next change. signal_wake_up(resume => true) is overused. None of ptrace/jctl callers actually want to wakeup a TASK_WAKEKILL task, but they can't specify the necessary mask. Turn signal_wake_up() into signal_wake_up_state(state), reintroduce signal_wake_up() as a trivial helper, and add ptrace_signal_wake_up() which adds __TASK_TRACED. This way ptrace_signal_wake_up() can work "inside" ptrace_request() even if the tracee doesn't have the TASK_WAKEKILL bit set.

2013-01-22f2fs: use _safe() version of list_for_eachDan Carpenter
This is calling list_del() inside a loop which is a problem when we try move to the next item on the list. I've converted it to use the _safe version. And also, as a cleanup, I've converted it to use list_for_each_entry instead of list_for_each.

2013-01-22f2fs: avoid issuing small bios due to several dirty node pagesJaegeuk Kim
If some small bios of dirty node pages are supposed to be issued during the sequential data writes, there-in well-produced consecutive data bios are able to be split by the small node bios, resulting in performance degradation. So, let's collect a number of dirty node pages until reaching a threshold. And, by default, I set the threshold as 2MB, a segment size. This improves sequential write performance on i5, 512GB SSD (830 w/ SATA2) as follows.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus Felipe writes: usb: fixes for v3.8-rc5 Finally we have a build fix for fsl-mxc-udc UDC driver. We also have a fix for ep0 maxburst setting on DWC3 which could confuse the HW if we tell it we had way too many streams on that endpoint when it _has_ to be only one. cppi_dma support for MUSB got a fix when running as a module. By dropping the wrong __init annotation, the function will be available even when we're modules and we're done with .init.text section. Last, but not least, we have a fix on FunctionFS which was causing a bug on our option parsing algorithm.
2013-01-21ftrace: Be first to run code modification on modulesSteven Rostedt
If some other kernel subsystem has a module notifier, and adds a kprobe to a ftrace mcount point (now that kprobes work on ftrace points), when the ftrace notifier runs it will fail and disable ftrace, as well as kprobes that are attached to ftrace points. Here's the error: WARNING: at kernel/trace/ftrace.c:1618 ftrace_bug+0x239/0x280() Hardware name: Bochs Modules linked in: fat(+) stap_56d28a51b3fe546293ca0700b10bcb29__8059(F) nfsv4 auth_rpcgss nfs dns_resolver fscache xt_nat iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 nf_nat nf_conntrack lockd sunrpc ppdev parport_pc parport microcode virtio_net i2c_piix4 drm_kms_helper ttm drm i2c_core [last unloaded: bid_shared] Pid: 8068, comm: modprobe Tainted: GF 3.7.0-0.rc8.git0.1.fc19.x86_64 #1 Call Trace: [<ffffffff8105e70f>] warn_slowpath_common+0x7f/0xc0 [<ffffffff81134106>] ? __probe_kernel_read+0x46/0x70 [<ffffffffa0180000>] ? 0xffffffffa017ffff [<ffffffffa0180000>] ? 0xffffffffa017ffff [<ffffffff8105e76a>] warn_slowpath_null+0x1a/0x20 [<ffffffff810fd189>] ftrace_bug+0x239/0x280 [<ffffffff810fd626>] ftrace_process_locs+0x376/0x520 [<ffffffff810fefb7>] ftrace_module_notify+0x47/0x50 [<ffffffff8163912d>] notifier_call_chain+0x4d/0x70 [<ffffffff810882f8>] __blocking_notifier_call_chain+0x58/0x80 [<ffffffff81088336>] blocking_notifier_call_chain+0x16/0x20 [<ffffffff810c2a23>] sys_init_module+0x73/0x220 [<ffffffff8163d719>] system_call_fastpath+0x16/0x1b ---[ end trace 9ef46351e53bbf80 ]--- ftrace failed to modify [<ffffffffa0180000>] init_once+0x0/0x20 [fat] actual: cc:bb:d2:4b:e1 A kprobe was added to the init_once() function in the fat module on load. But this happened before ftrace could have touched the code. As ftrace didn't run yet, the kprobe system had no idea it was a ftrace point and simply added a breakpoint to the code (0xcc in the cc:bb:d2:4b:e1). Then when ftrace went to modify the location from a call to mcount/fentry into a nop, it didn't see a call op, but instead it saw the breakpoint op and not knowing what to do with it, ftrace shut itself down. The solution is to simply give the ftrace module notifier the max priority. This should have been done regardless, as the core code ftrace modification also happens very early on in boot up. This makes the module modification closer to core modification.

2013-01-20module: fix missing module_mutex unlockLinus Torvalds
Commit 1fb9341ac348 ("module: put modules in list much earlier") moved some of the module initialization code around, and in the process changed the exit paths too. But for the duplicate export symbol error case the change made the ddebug_cleanup path jump to after the module mutex unlock, even though it happens with the mutex held. Rusty has some patches to split this function up into some helper functions, hopefully the mess of complex goto targets will go away eventually.

While working on a new kms driver that uses memcpy, if I overallocated bo's up to the memory limits, and eviction failed, then machine would oops soon after due to having an active bo with an already freed drm_mm embedded in it, freeing it a second time didn't end well.

2013-01-18usb: musb: cppi_dma: drop '__init' annotationSergei Shtylyov
This patch fixes the following: WARNING: vmlinux.o(.text+0x1e709c): Section mismatch in reference from the funct ion dma_controller_create() to the function .init.text:cppi_controller_start() The function dma_controller_create() references the function __init cppi_controller_start(). This is often because dma_controller_create lacks a __init annotation or the annotation of cppi_controller_start is wrong. This warning is there due to the deficiency in the commit 07a67bbb (usb: musb: Make dma_controller_create __devinit). Since the start() method is only called from musb_init_controller() which is not annotated, drop '__init' annotation from cppi_controller_start() and also cppi_pool_init() since it gets called from that function, to avoid another section mismatch warning...

The tty is NULL when the port is hanging up. chase_port() needs to check for this. This patch is intended for stable series. The behavior was observed and tested in Linux 3.2 and 3.7.1.

Add support for the UART device present in Broadcom TruManage capable NetXtreme chips (ie: 5761m 5762, and 5725). This implementation has a hidden transmit FIFO, so running in single-byte interrupt mode results in too many interrupts. The UART_CAP_HFIFO capability was added to track this. It continues to reload the THR as long as the THRE and TSRE bits are set in the LSR up to a specified limit (1024 is used here).

2013-01-17pty: return EINVAL for TIOCGPTN for BSD ptysJiri Slaby
Commit bbb63c514a3464342967237a51a21ea8f61ab951 (drivers:tty:fix up ENOIOCTLCMD error handling) changed the default return value from tty ioctl to be ENOTTY and not EINVAL. This is appropriate. But in case of TIOCGPTN for the old BSD ptys glibc started failing because it expects EINVAL to be returned. Only then it continues to obtain the pts name the other way around. So fix this case by explicit return of EINVAL in this case.
