clocksource: Use a plain u64 instead of cycle_t

2016-12-25T10:04:12Z

There is no point in having an extra type for extra confusion. u64 is unambiguous. Conversion was done with the following coccinelle script: @rem@ @@ -typedef u64 cycle_t; @fix@ typedef cycle_t; @@ -cycle_t +u64 Signed-off-by: Thomas Gleixner Cc: Peter Zijlstra Cc: John Stultz

Replace with globally

2016-12-24T19:46:01Z

This was entirely automated, using the script by Al: PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*' sed -i -e "s!$PATT!#include !" \ $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h) to do the replacement at the end of the merge window.

arch/avr32: add option to skip sync on DMA map

2016-12-15T00:04:07Z

The use of DMA_ATTR_SKIP_CPU_SYNC was not consistent across all of the DMA APIs in the arch/arm folder. This change is meant to correct that so that we get consistent behavior.

Pull locking updates from Ingo Molnar: "The tree got pretty big in this development cycle, but the net effect is pretty good: 115 files changed, 673 insertions(+), 1522 deletions(-) The main changes were: - Rework and generalize the mutex code to remove per arch mutex primitives. (Peter Zijlstra) - Add vCPU preemption support: add an interface to query the preemption status of vCPUs and use it in locking primitives - this optimizes paravirt performance. (Pan Xinhui, Juergen Gross, Christian Borntraeger) - Introduce cpu_relax_yield() and remov cpu_relax_lowlatency() to clean up and improve the s390 lock yielding machinery and its core kernel impact. (Christian Borntraeger) - Micro-optimize mutexes some more. (Waiman Long) - Reluctantly add the to-be-deprecated mutex_trylock_recursive() interface on a temporary basis, to give the DRM code more time to get rid of its locking hacks. Any other users will be NAK-ed on sight. (We turned off the deprecation warning for the time being to not pollute the build log.)

avr32: wire up pkey syscalls

2016-12-12T08:24:13Z

This patch wires up the new pkey_mprotect, pkey_alloc and pkey_free syscalls on AVR32.

AVR32-pio: Replace two seq_printf() calls by seq_puts() in pio_bank_show()

2016-12-12T08:05:46Z

Strings which did not contain data format specifications should be put into a sequence. Thus use the corresponding function "seq_puts". This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring

AVR32-pio: Use seq_putc() in pio_bank_show()

2016-12-12T08:05:46Z

A single character (line break) should be put into a sequence. Thus use the corresponding function "seq_putc". This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring

AVR32-clock: Combine nine seq_printf() calls into one call in clk_show()

2016-12-12T08:05:46Z

Some data were printed into a sequence by nine separate function calls. Print the same data by a single function call instead. Signed-off-by: Markus Elfring

AVR32-clock: Use seq_putc() in two functions

2016-12-12T08:05:46Z

A single character (line break) should be put into two sequences. Thus use the corresponding function "seq_putc". This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring
