2009-11-26block: add helpers to run flush_dcache_page() against a bio and a request's ↵Ilya Loginov
pages Mtdblock driver doesn't call flush_dcache_page for pages in request. So, this causes problems on architectures where the icache doesn't fill from the dcache or with dcache aliases. The patch fixes this. The ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE symbol was introduced to avoid pointless empty cache-thrashing loops on architectures for which flush_dcache_page() is a no-op. Every architecture was provided with this flush pages on architectires where ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE is equal 1 or do nothing otherwise. See "fix mtd_blkdevs problem with caches on some architectures" discussion on LKML for more information.

2009-11-09sh: Account for cache aliases in flush_icache_range()Matt Fleming
The icache may also contain aliases so we must account for them just like we do when manipulating the dcache. We usually get away with aliases in the icache because the instructions that are read from memory are read-only, i.e. they never change. However, the place where this bites us is when the code has been modified. Signed-off-by: Matt Fleming <matt@console-pimps.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-11-04ALSA: sh: add SuperH DAC audio driver for ALSA V4Rafael Ignacio Zurita
This is a port of the sound/oss/sh_dac_audio.c driver. The driver uses an on-chip 8-bit D/A converter, which has a speaker connected to one of its channels, found in several ancient HP machines. For interrupts it uses a high-resolution timer (hrtimer). Tested on SH7709 based hp6xx (HP Jornada 680/690 and HP Palmtop 620lx/660lx). Also, since OSS Emulation works, the old OSS sound/oss/sh_dac_audio.c driver would be obsolete soon, and it could be removed.

2009-10-27sh: Fix hugetlbfs dependencies for SH-3 && MMU configurations.Paul Mundt
The hugetlb dependencies presently depend on SUPERH && MMU while the hugetlb page size definitions depend on CPU_SH4 or CPU_SH5. This unfortunately allows SH-3 + MMU configurations to enable hugetlbfs without a corresponding HPAGE_SHIFT definition, resulting in the build blowing up. As SH-3 doesn't support variable page sizes, we tighten up the dependenies a bit to prevent hugetlbfs from being enabled. These days we also have a shiny new SYS_SUPPORTS_HUGETLBFS, so switch to using that rather than adding to the list of corner cases in fs/Kconfig.

2009-10-26sh: Check for return_to_handler when unwinding the stackMatt Fleming
When CONFIG_FUNCTION_GRAPH_TRACER is enabled the function graph tracer may patch return addresses on the stack with the address of return_to_handler(). This really confuses the DWARF unwinder because it will try find the caller of return_to_handler(), not the caller of the real return address. So teach the DWARF unwinder how to find the real return address whenever it encounters return_to_handler(). This patch does not cope very well when multiple return addresses on the stack have been patched. To make it work properly it would require state to track how many return_to_handler()'s have been seen so that we'd know where to look in current->curr_ret_stack[]. So for now, instead of trying to handle this, just moan if more than one return address on the stack has been patched.

2009-10-16sh: Fix up single page flushing to use PAGE_SIZE.Valentin Sitdikov
Presently The SH-4 cache flushing code uses flush_cache_4096() for most of the real flushing work, which breaks down to a fixed 4096 unroll and increment. Not only is this sub-optimal for larger page sizes, it's also uncovered a bug in sh4_flush_dcache_page() when large page sizes are used and we have no cache aliases -- resulting in only a part of the page's D-cache lines being written back.

2009-10-12net: Introduce recvmmsg socket syscallArnaldo Carvalho de Melo
Meaning receive multiple messages, reducing the number of syscalls and net stack entry/exit operations. Next patches will introduce mechanisms where protocols that want to optimize this operation will provide an unlocked_recvmsg operation. This takes into account comments made by: . Paul Moore: sock_recvmsg is called only for the first datagram, sock_recvmsg_nosec is used for the rest. . Caitlin Bestler: recvmmsg now has a struct timespec timeout, that works in the same fashion as the ppoll one. If the underlying protocol returns a datagram with MSG_OOB set, this will make recvmmsg return right away with as many datagrams (+ the OOB one) it has received so far. . Rémi Denis-Courmont & Steven Whitehouse: If we receive N < vlen datagrams and then recvmsg returns an error, recvmmsg will return the successfully received datagrams, store the error and return it in the next call. This paves the way for a subsequent optimization, sk_prot->unlocked_recvmsg, where we will be able to acquire the lock only at batch start and end, not at every underlying recvmsg call.

2009-10-13sh: force dcache flush if dcache_dirty bit set.Paul Mundt
This too follows the ARM change, given that the issue at hand applies to all platforms that implement lazy D-cache writeback. This fixes up the case when a page mapping disappears between the flush_dcache_page() call (when PG_dcache_dirty is set for the page) and the update_mmu_cache() call -- such as in the case of swap cache being freed early. This kills off the mapping test in update_mmu_cache() and switches to simply testing for PG_dcache_dirty.

2009-10-09sh: Don't allocate smaller sized mappings on every iterationMatt Fleming
Currently, we've got the less than ideal situation where if we need to allocate a 256MB mapping we'll allocate four entries like so, entry 1: 128MB entry 2: 64MB entry 3: 16MB entry 4: 16MB This is because as we execute the loop in pmb_remap() we will progressively try mapping the remaining address space with smaller and smaller sizes. This isn't good because the size we use on one iteration may be the perfect size to use on the next iteration, for instance when the initial size is divisible by one of the PMB mapping sizes. With this patch, we now only need two entries in the PMB to map 256MB of address space, entry 1: 128MB entry 2: 128MB Signed-off-by: Matt Fleming <matt@console-pimps.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
