2014-01-22Android: Add support for 32-bit Binder calls in a 64-bit kernelBintian Wang
Android's IPC, Binder, does not support calls from a 32-bit userspace in a 64 bit kernel. This patch adds support for syscalls coming from a 32-bit userspace in a 64-bit kernel. Most of the changes were applied to types that change sizes between 32 and 64 bit world. This will also fix some of the issues around checking the size of an incoming transaction package in the ioctl switch. Since the transaction's ioctl number are generated using _IOC(dir,type,nr,size), a different userspace size will generate a different ioctl number, thus switching by _IOC_NR is a better solution. The patch has been successfully tested on ARMv8 AEM and Versatile Express V2P-CA9.

2014-01-14ion: Add carveout and chunk heaps to dummy driverJohn Stultz
Add support to the dummy driver for basic carveout and chunk heaps. Since we're generating these heaps at module_init, and we want this driver to be generic enough to be tested on any arch, we don't have the ability to alloc bootmem, so both of these heaps are conventionally allocated using alloc_pages(), which limits us to 4M in size. Should look into using CMA for heap allocation eventually, but this provides enough to test the basic functionality of the heaps.

2014-01-09staging: comedi: 8255_pci: fix for newer PCI-DIO48HIan Abbott
commit 0283f7a100882684ad32b768f9f1ad81658a0b92 upstream. At some point, Measurement Computing / ComputerBoards redesigned the PCI-DIO48H to use a PLX PCI interface chip instead of an AMCC chip. This meant they had to put their hardware registers in the PCI BAR 2 region instead of PCI BAR 1. Unfortunately, they kept the same PCI device ID for the new design. This means the driver recognizes the newer cards, but doesn't work (and is likely to screw up the local configuration registers of the PLX chip) because it's using the wrong region. Since the PCI subvendor and subdevice IDs were both zero on the old design, but are the same as the vendor and device on the new design, we can tell the old design and new design apart easily enough. Split the existing entry for the PCI-DIO48H in `pci_8255_boards[]` into two new entries, referenced by different entries in the PCI device ID table `pci_8255_pci_table[]`. Use the same board name for both entries.

2013-12-19ion: fix overflow and list bugs in system heapColin Cross
Fix a few bugs in ion_system_heap: Initialize the list node in the info block. Don't store size_remaining in a signed long, allocating >2GB could overflow, resulting in a call to sg_alloc_table with nents=0 which panics. alloc_largest_available will never return a block larger than size_remanining, so it can never go negative. Limit a single allocation to half of all memory. Prevents a large allocation from taking down the whole system.

2013-12-19ion: Add private buffer flag to skip page pooling on freeMitchel Humpherys
Currently, when we free a buffer it might actually just go back into a heap-specific page pool rather than going back to the system. This poses a problem because sometimes (like when we're running a shrinker in low memory conditions) we need to force the memory associated with the buffer to truly be relinquished to the system rather than just going back into a page pool. There isn't a use case for this flag by Ion clients, so make it a private flag. The main use case right now is to provide a mechanism for the deferred free code to force stale buffers to bypass page pooling.

2013-12-19ion: move shrinker out of heapsColin Cross
Every heap that uses deferred frees is going to need a shrinker to shrink the freelist under memory pressure. Rather than requiring each heap to implement a shrinker, automatically register a shrinker if the deferred free flag is set. The system heap also needs to shrink its page pools, so add a shrink function to the heap ops that will be called after shrinking the freelists.

2013-12-19ion_test: Add compat_ioctl support (v2)John Stultz
Prior to subitting this, Colin reworked the compat_ioctl support for the ion_test driver, moving the structure to be the same size on both 32 and 64 bit architectures. Two small things were left out. The compat_ioctl ptr assignment, and the fact that despite having uniform sized types in the structure, the structure pads out to different sizes on different arches. This patch resolves this issue by adding a padding entry after the write flag, and adding the compat_ioctl ptr.

2013-12-19staging: ion: Avoid using rt_mutexes directlyJohn Stultz
RT_MUTEXES can be configured out of the kernel, causing compile problems with ION. To quote Colin: "rt_mutexes were added with the deferred freeing feature. Heaps need to return zeroed memory to userspace, but zeroing the memory on every allocation was causing performance issues. We added a SCHED_IDLE thread to zero memory in the background after freeing, but locking the heap from the SCHED_IDLE thread might block a high priority allocation thread for a long time. The lock is only used to protect the heap's free_list and free_list_size members, and is not held for any long or sleeping operations. Converting to a spinlock should prevent priority inversion without using the rt_mutex. I'd also rename it to free_lock to so it doesn't get used as a general heap lock." Thus this patch converts the rt_mutex usage to a spinlock and renames the lock free_lock to be more clear as to its use. I also had to change a bit of logic in ion_heap_freelist_drain() to safely avoid list corruption.
