* Revert "exynos-mem: Fix major security hole"Espen Fjellvær Olsen2013-01-091-13/+1
| | | | This reverts commit 9c1d0f487d28417858778d094f2eb98eb47ea2f7.
* exynos-mem: Fix major security holeAndrei F2012-12-201-1/+13
| | | | | | | | | | | | | | | This fixes the exynos-mem device security hole. The driver allowed any user to access all of the device's lowmem through the provided mmap functionality. We create a small little framework collecting the actual CMA memory blocks that exist on the device; they are the root cause of the existence of this device driver. We white-list only the CMA memory spaces as parameters to the mmap function and deny access to any other memory space requests. We furthermore just allow access to the "s3c-fimc" memory block as this is seemingly the only space which upon access denial actually breaks functionality.

| * genirq: replace irq_gc_ack() with {set,clr}_bit variants (fwd)Simon Guinot2011-07-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a regression introduced by e59347a "arm: orion: Use generic irq chip". Depending on the device, interrupts acknowledgement is done by setting or by clearing a dedicated register. Replace irq_gc_ack() with some {set,clr}_bit variants allows to handle both cases. Note that this patch affects the following SoCs: Davinci, Samsung and Orion. Except for this last, the change is minor: irq_gc_ack() is just renamed into irq_gc_ack_set_bit(). For the Orion SoCs, the edge GPIO interrupts support is currently broken. irq_gc_ack() try to acknowledge a such interrupt by setting the corresponding cause register bit. The Orion GPIO device expect the opposite. To fix this issue, the irq_gc_ack_clr_bit() variant is used. Tested on Network Space v2.

The reason is that PWM Timer which is for HRTimer was used before its initialization.

* ARM: EXYNOS4: Implement Clock gating for System MMUKyongHo Cho2011-03-151-0/+6
| | | | | | | | | | | | | This patch includes the implementation of the clock gating for System MMU. Initially, all System MMUs are not asserted the system clock. Asserting the system clock to a System MMU is enabled only when s5p_sysmmu_enable() is called. Likewise, it is disabled only when s5p_sysmmu_disable() is called. Therefore, clock gating on System MMUs are still invisible to the outside of the System MMU driver.
