      ARM: omap: fix typo on timer cleanup · 73f14f6d
      由 Olof Johansson 提交于 
      Fix 32 vs 32k typo:

arch/arm/mach-omap2/timer.c: In function 'omap4_local_timer_init':
arch/arm/mach-omap2/timer.c:633:2: error: implicit declaration of function 'omap4_sync32_timer_init' [-Werror=implicit-function-declaration]
arch/arm/mach-omap2/timer.c: At top level:
arch/arm/mach-omap2/timer.c:610:2: warning: 'omap4_sync32k_timer_init' defined but not used [-Wunused-function]

Also, mark the omap4_local_timer_init() stub as __init (and take off
the explicit inline and let the compiler do the work instead).

      [PARISC] fix user-triggerable panic on parisc · 441a179d
      由 Al Viro 提交于 
      int sys32_rt_sigprocmask(int how, compat_sigset_t __user *set, compat_sigset_t __user *oset,
                                    unsigned int sigsetsize)
{
        sigset_t old_set, new_set;

        if (set && get_sigset32(set, &new_set, sigsetsize))

get_sigset32(compat_sigset_t __user *up, sigset_t *set, size_t sz)
{
        compat_sigset_t s;
        int r;

        if (sz != sizeof *set) panic("put_sigset32()");

In other words, rt_sigprocmask(69, (void *)69, 69) done by 32bit process
will promptly panic the box.

      ARM - OMAP: ads7846: fix pendown debounce setting · 0a0d6285
      由 Igor Grinberg 提交于 
      Commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code) have enabled the
pendown GPIO debounce time setting by the below sequence:

  gpio_request_one()
  gpio_set_debounce()
  gpio_free()

It also revealed a bug in the OMAP GPIO handling code which prevented
the GPIO debounce clock to be disabled and CORE transition to low power
states.

Commit c9c55d92 (gpio/omap: fix off-mode bug: clear debounce settings on
free/reset) fixes the OMAP GPIO handling code by making sure that the
GPIO debounce clock gets disabled if no GPIO is requested from current
bank.

While fixing the OMAP GPIO handling code (in the right way), the above
commit makes the gpio_request->set_debounce->free sequence invalid as
after freeing the GPIO, the debounce settings are lost.

Fix the debounce settings by moving the debounce initialization to the
actual GPIO requesting code - the ads7846 driver.

      由 Igor Grinberg 提交于 
      cm-t3517 starting from revision 1.2 does not have the 32K oscilator
wired to the AM3517 SoC.
Therefore switch to use the GPTIMER for system clock.

      ARM: OMAP2+: timer: remove CONFIG_OMAP_32K_TIMER · 6f80b3bb
      由 Igor Grinberg 提交于 
      CONFIG_OMAP_32K_TIMER is kind of standing on the single zImage way.
Make OMAP2+ timer code independant from the CONFIG_OMAP_32K_TIMER
setting.
To remove the dependancy, several conversions/additions had to be done:
1) Timer initialization functions are named by the platform
   name and the clock source in use.
   This also makes it possible to define and use the GPTIMER as the
   clock source instead of the 32K timer on platforms that do not have
   the 32K timer ip block or the 32K timer is not wired on the board.
   Currently, the the timer is chosen in the machine_desc structure on
   per board basis. Later, DT should be used to choose the timer.
2) Settings under the CONFIG_OMAP_32K_TIMER option are used as defaults
   and those under !CONFIG_OMAP_32K_TIMER are removed.
   This removes the CONFIG_OMAP_32K_TIMER on OMAP2+ timer code.
3) Since we have all the timers defined inside machine_desc structure
   and we no longer need the fallback to gp_timer clock source in case
   32k_timer clock source is unavailable (namely on AM33xx), we no
   longer need the #ifdef around omap2_sync32k_clocksource_init()
   function. Remove the #ifdef CONFIG_OMAP_32K_TIMER around the
   omap2_sync32k_clocksource_init() function.

      m68k: fix sigset_t accessor functions · 34fa78b5
      由 Andreas Schwab 提交于 
      The sigaddset/sigdelset/sigismember functions that are implemented with
bitfield insn cannot allow the sigset argument to be placed in a data
register since the sigset is wider than 32 bits.  Remove the "d"
constraint from the asm statements.

The effect of the bug is that sending RT signals does not work, the signal
number is truncated modulo 32.

      ARM: integrator: push down SC dependencies · 379df279
      由 Linus Walleij 提交于 
      This pushes the dependencies on the Integrator/AP system
controller (SC) down into the PCI V3 driver and the
AP-specific board file.

First, the platform data for the PL010 UART is moved into
the integrator_ap.c board file, and the Integrator/CP is
assigned with NULL pdata. This way the callback functions
can reference the dynamically remapped AP syscon address
in both the ATAG and DT boot path, and this remapping
is localized to the board file.

Second the PCIv3 driver is making its own dynamic remapping
of the SC for the few registers it is using. When we
convert the PCIv3 driver over to using device tree having a
dynamically assigned base address will be useful, but we
will have to use the definition from <mach/platform.h> for
now, the only improvement is that it's done dynamically.
