* xstrdup: don't panic on xstrdup(NULL)Uwe Kleine-König2016-09-121-1/+6
| | | | | | | | | | | | Instead return just NULL. This matches the behaviour of kstrdup in the kernel and xstrdup in busybox. This fixes a panic with CONFIG_CMD_MAGICVAR=y and CONFIG_CMD_MAGICVAR_HELP unset in magicvar_add() where description is always NULL.

| | | | | | | | | | In order to clear a bitmask, "Set" bit has to be '0' and "Mask" bit '1'. Since "Set" is bit 4 and "Mask" is bit 3 this leaves us with a overal or-mask of 1 << 3. Orginal code was doing the inverse and setting bit #4 to '1' bit #3 to '0'. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: vector_table: Fix creation of second level page tableSascha Hauer2016-08-261-1/+1
| | | | | | | | | | | | | | | | | The second level page tables can only start at a 1MiB section boundary, so instead of calling arm_create_pte() with the high vector address (which is 0xffff0000, not 1MiB aligned) we have to call it with 0xfff00000 to correctly create a second level page table. The old values broke SoCs which have peripherals in the upper 1MiB area, like for example the Atmel AT91RM9200. On these Socs we correctly created the vector page, but the pages around it did not have a 1:1 mapping anymore which led to unreachable peripherals.

| * video/backlight-pwm: properly handle the case of an empty ↵iw3gtf@arcor.de2016-07-151-7/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'brightness-levels' in the device tree. In case of an empty 'brightness-levels' array in the device tree or a non empty one but containing only zeros the value of 'pwm_backlight->scale' would remain 0 possibly causing a division by zero in the function compute_duty_cycle(). To fix it we check the computed value in case we actually have a 'brightness-levels' array in the device tree otherwise we implicitly assume a simple array of the form { 0, 1, 2, ..., 100 } and set the scale to 100.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We now have code to save the nv variables without saving the rest of the environment.

With this the additional 'saveenv' step becomes unnecessary. The nv variables are stored in the environment and the estasblished behaviour is that files in the environment must be manually saved using 'saveenv'. This behaviour shall be kept for now, so this patch cannot just call 'saveenv' since that would save the modified environment files aswell. Instead we read the environment from the device, modifiy the nv variables and save the environment back. Since this changes a long existing behaviour messages are printed the first time a nv variable is modified and during shutdown when the variables are actually saved.
