2013-07-03coredump: kill call_count, add core_name_sizeOleg Nesterov1-9/+10
Imho, "atomic_t call_count" is ugly and should die. It buys nothing and in fact it can grow more than necessary, expand doesn't check if it was already incremented by another task. Kill it, and introduce "static int core_name_size" updated by expand_corename(). This is obviously racy too but harmless, and core_name_size never grows for no reason. We do not bother to to calculate the "right" new size, we simply do kmalloc(size_we_need) and use ksize() to rely on kmalloc_index's decision. Finally change format_corename() to use expand_corename(), krealloc(NULL) is fine.

2013-07-03coredump: kill cn_escape(), introduce cn_esc_printf()Oleg Nesterov1-23/+21
The usage of cn_escape() looks really annoying, imho this sequence needs a wrapper. And it is buggy. If cn_printf() does expand_corename() cn_escape() writes to the freed memory. Introduce cn_esc_printf() which hopefully does this all right. It records the index before cn_vprintf(), not "char *" which is no longer valid (in general) after krealloc().

2013-07-03coredump: format_corename() can leak cn->corenameOleg Nesterov1-11/+7
do_coredump() assumes that format_corename() can only fail if expand_corename() fails and frees cn->corename. This is not true, for example cn_print_exe_file() can fail and in this case nobody frees cn->corename. Change do_coredump() to always do kfree(cn->corename) after it calls format_corename() (NULL is fine), change expand_corename() to do nothing if kmalloc() fails.

2013-07-03ptrace: add ability to get/set signal-blocked maskAndrey Vagin2-2/+45
crtools uses a parasite code for dumping processes. The parasite code is injected into a process with help PTRACE_SEIZE. Currently crtools blocks signals from a parasite code. If a process has pending signals, crtools wait while a process handles these signals. This method is not suitable for stopped tasks. A stopped task can have a few pending signals, when we will try to execute a parasite code, we will need to drop SIGSTOP, but all other signals must remain pending, because a state of processes must not be changed during checkpointing. This patch adds two ptrace commands to set/get signal-blocked mask. I think gdb can use this commands too.

First of all, it is calculated total file nodes in file system as (desc_blocks_count * groups_per_desc_block * entries_per_group). Then, it is calculated free inodes count as difference the total file nodes and used inodes count.

2013-07-03drivers/rtc/rtc-sirfsoc.c: add rtc drivers for CSR SiRFprimaII and SiRFatlasVIXianglong Du5-2/+485
On CSR SiRFprimaII/atlasVI, there is a programmable 16-bit divider (RTC_DIV) that divides the input 32.768KHz clock to the frequency that users need (E.g. 1 Hz). The divided real-time clock will be used to drive a 32-bit counter (RTC_COUNTER) that provides users with the actual time. In each cycle of the divided real-time clock, there is a Hertz interrupt generated to the RISC. Users can also configure an alarm (RTC_ALARM). When RTC_COUNTER matches the alarm, there will be an alarm interrupt generated to the RISC. The system RTC can generate an alarm wake-up signal to notify the power controller to wake up from power saving mode.

2013-07-03rtc: omap: restore back (hard-code) wakeup supportHebbar Gururaja1-0/+2
rtc-omap driver modules is used both by OMAP1/2, Davinci SoC platforms. However, rtc wake support on OMAP1 is broken. Hence the device_init_wakeup() was removed from rtc-omap driver and moved to platform board files that supported it (DA850/OMAP-L138). [1] However, recently [2] it was suggested that driver should always do a device_init_wakeup(dev, true). Platforms that don't want/need wakeup support can disable it from userspace via: echo disabled > /sys/devices/.../power/wakeup Also, with the new DT boot-up, board file doesn't exist and hence there is no way to have device wakeup support rtc. The fix for above issues, is to hard code device_init_wakeup() inside driver and let platforms that don't need this, handle it through the sysfs power entry.

Since the cmos interrupt handler may now be run before the rtc_cmos is resumed, this can cause the interrupt handler to ignore an alarm since the alarm bit is not set in the rtc control register.

2013-07-03drivers/rtc/rtc-twl.c: ensure IRQ is wakeup enabledKevin Hilman1-2/+14
Currently, the RTC IRQ is never wakeup-enabled so is not capable of bringing the system out of suspend. On OMAP platforms, we have gotten by without this because the TWL RTC is on an I2C-connected chip which is capable of waking up the OMAP via the IO ring when the OMAP is in low-power states. However, if the OMAP suspends without hitting the low-power states (and the IO ring is not enabled), RTC wakeups will not work because the IRQ is not wakeup enabled. To fix, ensure the RTC IRQ is wakeup enabled whenever the RTC alarm is set.
