2013-01-07b43: Fix firmware loading when driver is built into the kernelLarry Finger
Recent versions of udev cause synchronous firmware loading from the probe routine to fail because the request to user space would time out. The original fix for b43 (commit 6b6fa58) moved the firmware load from the probe routine to a work queue, but it still used synchronous firmware loading. This method is OK when b43 is built as a module; however, it fails when the driver is compiled into the kernel. This version changes the code to load the initial firmware file using request_firmware_nowait(). A completion event is used to hold the work queue until that file is available. This driver reads several firmware files - the remainder can be read synchronously. On some test systems, the async read fails; however, a following synch read works, thus the async failure falls through to the sync try.

2013-01-07sctp: fix Kconfig bug in default cookie hmac selectionAlex Elder
Commit 0d0863b02002 ("sctp: Change defaults on cookie hmac selection") added a "choice" to the sctp Kconfig file. It introduced a bug which led to an infinite loop when while running "make oldconfig". The problem is that the wrong symbol was defined as the default value for the choice. Using the correct value gets rid of the infinite loop. Note: if CONFIG_SCTP_COOKIE_HMAC_SHA1=y was present in the input config file, both that and CONFIG_SCTP_COOKIE_HMAC_MD5=y be present in the generated config file.

2013-01-06tcp: fix MSG_SENDPAGE_NOTLAST logicEric Dumazet
commit 35f9c09fe9c72e (tcp: tcp_sendpages() should call tcp_push() once) added an internal flag : MSG_SENDPAGE_NOTLAST meant to be set on all frags but the last one for a splice() call. The condition used to set the flag in pipe_to_sendpage() relied on splice() user passing the exact number of bytes present in the pipe, or a smaller one. But some programs pass an arbitrary high value, and the test fails. The effect of this bug is a lack of tcp_push() at the end of a splice(pipe -> socket) call, and possibly very slow or erratic TCP sessions. We should both test sd->total_len and fact that another fragment is in the pipe (pipe->nrbufs > 1) Many thanks to Willy for providing very clear bug report, bisection and test programs.

* pm-sleep: PM: Move disabling/enabling runtime PM to late suspend/early resume
2013-01-06PM: Move disabling/enabling runtime PM to late suspend/early resumeRafael J. Wysocki
Currently, the PM core disables runtime PM for all devices right after executing subsystem/driver .suspend() callbacks for them and re-enables it right before executing subsystem/driver .resume() callbacks for them. This may lead to problems when there are two devices such that the .suspend() callback executed for one of them depends on runtime PM working for the other. In that case, if runtime PM has already been disabled for the second device, the first one's .suspend() won't work correctly (and analogously for resume). To make those issues go away, make the PM core disable runtime PM for devices right before executing subsystem/driver .suspend_late() callbacks for them and enable runtime PM for them right after executing subsystem/driver .resume_early() callbacks for them. This way the potential conflitcs between .suspend_late()/.resume_early() and their runtime PM counterparts are still prevented from happening, but the subtle ordering issues related to disabling/enabling runtime PM for devices during system suspend/resume are much easier to avoid.

2013-01-04printk: fix incorrect length from print_time() when seconds > 99999Roland Dreier
print_prefix() passes a NULL buf to print_time() to get the length of the time prefix; when printk times are enabled, the current code just returns the constant 15, which matches the format "[%5lu.%06lu] " used to print the time value. However, this is obviously incorrect when the whole seconds part of the time gets beyond 5 digits (100000 seconds is a bit more than a day of uptime). The simple fix is to use snprintf(NULL, 0, ...) to calculate the actual length of the time prefix. This could be micro-optimized but it seems better to have simpler, more readable code here. The bug leads to the syslog system call miscomputing which messages fit into the userspace buffer. If there are enough messages to fill log_buf_len and some have a timestamp >= 100000, dmesg may fail with: # dmesg klogctl: Bad address When this happens, strace shows that the failure is indeed EFAULT due to the kernel mistakenly accessing past the end of dmesg's buffer, since dmesg asks the kernel how big a buffer it needs, allocates a bit more, and then gets an error when it asks the kernel to fill it: syslog(0xa, 0, 0) = 1048576 mmap(NULL, 1052672, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fa4d25d2000 syslog(0x3, 0x7fa4d25d2010, 0x100008) = -1 EFAULT (Bad address) As far as I can see, the bug has been there as long as print_time(), which comes from commit 084681d14e42 ("printk: flush continuation lines immediately to console") in 3.5-rc5.

2013-01-04drivers/rtc/rtc-vt8500.c: fix handling of data passed in struct rtc_timeTony Prisk
tm_mon is 0..11, whereas vt8500 expects 1..12 for the month field, causing invalid date errors for January, and causing the day field to roll over incorrectly. The century flag is only handled in vt8500_rtc_read_time, but not set in vt8500_rtc_set_time. This patch corrects the behaviour of the century flag.

2013-01-04drivers/rtc/rtc-vt8500.c: correct handling of CR_24H bitfieldTony Prisk
Control register bitfield for 12H/24H mode is handled incorrectly. Setting CR_24H actually enables 12H mode. This patch renames the define and changes the initialization code to correctly set 24H mode.
