Commit f44f7f96 ("RTC: Initialize kernel state from RTC") introduced a potential infinite loop. If an alarm time contains a wildcard month and an invalid day (> 31), or a wildcard year and an invalid month (>= 12), the loop searching for the next matching date will never terminate. Treat the invalid values as wildcards. Fixes <http://bugs.debian.org/646429>, <http://bugs.debian.org/653331> Reported-by:

In ancient times it was necessary to manually initialize the bus field of an spi_driver to spi_bus_type. These days this is done in spi_driver_register(), so we can drop the manual assignment. The patch was generated using the following coccinelle semantic patch: // <smpl> @@ identifier _driver; @@ struct spi_driver _driver = { .driver = { - .bus = &spi_bus_type, }, }; // </smpl> Signed-off-by:Lars-Peter Clausen <lars@metafoo.de> Cc: John Stultz <john.stultz@linaro.org> Cc: Alessandro Zummo <a.zummo@towertech.it> Cc: Grant Likely <grant.likely@secretlab.ca> Signed-off-by:

The rtc_calibration attribute allows user-space to get and set the AB8500's RtcCalibration register. The AB8500 will then use the value in this register to compensate for RTC drift every 60 seconds. [akpm@linux-foundation.org: coding-style fixes] Signed-off-by:

The resolution of msleep is related to HZ, so with HZ set to 100 any msleep of less than 10ms will become ~10ms. This is not what we want. Use the hrtimer-based usleep_range() and allow for some slack in the non-critical path so we have more control of what is happening here. Signed-off-by:

There is no way to track year in the i.MX1 RTC: Days Counter register is 9-bit wide only. Attempt to save date after 1970-01-01 plus 512 days causes endless loop in mxc_rtc_set_mmss(). Fix this by resetting year to 1970. [akpm@linux-foundation.org: use conventional comment layout] Signed-off-by:

Randomization of PIE load address is hard coded in binfmt_elf.c for X86 and ARM. Create a new Kconfig variable (CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE) for this and use it instead. Thus architecture specific policy is pushed out of the generic binfmt_elf.c and into the architecture Kconfig files. X86 and ARM Kconfigs are modified to select the new variable so there is no change in behavior. A follow on patch will select it for MIPS too. Signed-off-by:

Fix up type and cast spacing checks such that all occurences on a line are examined and reported. For example the line below has a valid cast and a bad type, but currently we check the cast first which is good and stop: u16* bar = (u16 *)baz; We will also only report one of the errors in this example: u16* bar = (u16*)bad; Move to iterating across all casts and all types, reporting any failure.

In the middle of a long definition or similar, there is no possibility of finding a smaller sub-statement. Optimise this case by skipping statement aquirey where there are no starts of statement (open brace '{' or semi-colon ';'). We are likely to scan slightly more than needed still but this is safest.

Improve the checking of arguments to memset and min/max tests. Move the checking of min/max to statement blocks instead of single line. Change $Constant to allow any case type 0x initiator and trailing ul specifier. Add $FuncArg type as any function argument with or without a cast. Print the whole statement when showing memset or min/max messages. Improve the memset with 0 as 3rd argument error message. There are still weaknesses in the $FuncArg and $Constant code as arbitrary parentheses and negative signs are not generically supported. [akpm@linux-foundation.org: fix per Andy] Signed-off-by:

When looking for a statement we currently run on through preprocessor commands. This means that a header file with just definitions is parsed over and over again combining all of the lines from the current line to the end of file leading to severe performance issues. Fix up context accumulation to track preprocessor commands and stop when reaching the end of them. At the same time vastly simplify the #define handling. Signed-off-by:

email header lines can look like signature tags. It's valid to have multiple email recipients on a single line but not valid to have multiple signatures on a single line. Validate signatures only when not in the email headers. Clear the $in_commit_log flag when the patch filename appears.

The btree_for_each API is implemented with macros that internally call btree_get_prev(), so if btree_get_prev() isn't exported then modules fail to link if they try to use one of the btree_for_each macros. Since the rest of the btree API is exported, we should keep things orthogonal and make this work too. Signed-off-by:
