* [MIPS] Fix FIXADDR_TOP for TX39/TX49.Atsushi Nemoto2006-06-29
| | | | | | | | | | | FIXADDR_TOP is used for HIGHMEM and for upper limit of vmalloc area on 32bit kernel. TX39XX and TX49XX have "reserved" segment in CKSEG3 area. 0xff000000-0xff3fffff on TX49XX and 0xff000000-0xfffeffff on TX39XX are reserved (unmapped, uncached) therefore can not be used as mapped area.

* Fix vsnprintf off-by-one bugLinus Torvalds2006-06-28
| | | | | | | | | | | | | | | The recent vsnprintf() fix introduced an off-by-one, and it's now possible to overrun the target buffer by one byte. The "end" pointer points to past the end of the buffer, so if we have to truncate the result, it needs to be done though "end[-1]".

| * [ARM] nommu: backtrace code must not reference a discarded sectionRussell King2006-06-28
| | | | | | | | | | | | | | | | | | The code in "1007:" is in the .fixup section, which in the mmuless case is discarded. Since this code is referenced from the .text section, it causes an link error. Move this code into the .text section instead. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * [ARM] nommu: Initial uCLinux support for MMU-based CPUsHyok S. Choi2006-06-28
| | | | | | | | | | | | | | | | | | | | In noMMU mode, various of functions which are defined in mm/proc-*.S is not valid or needed to be avoided. i.g. switch_mm is not needed, just returns and this makes the I & D caches are valid which shows great improvement of performance including task switching and IPC.

| * [ARM] nommu: prevent Xscale-based machines being selectedRussell King2006-06-28
| | | | | | | | | | | | | | | | | | Hyok says Intel Xscale is not currently supported by uCLinux. Rather than adding #error statements to the Xscale support files and causing !MMU+Xscale configurations to fail to build, prevent Xscale-based machines from being selected in !MMU mode.

| * [ARM] nommu: export flush_dcache_page()Hyok S. Choi2006-06-28
| | | | | | | | | | | | | | This is a trivial patch to export flush_dcache_page in mm/nommu.c. Signed-off-by: Hyok S. Choi <hyok.choi@samsung.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * [ARM] nommu: remove fault-armv, mmap and mm-armv files from nommu buildRussell King2006-06-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove fault-armv.o, mmap.o and mm-armv.o from uclinux builds - these are concerned with MMU-ful operations, and as such are redundant for uclinux. Since this also removes iotable_init() and iotable_init() is used extensively in the platform support files, just make it a no-op. Based upon a couple of patches by Hyok. Signed-off-by: Hyok S. Choi <hyok.choi@samsung.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * [ARM] Remove TABLE_SIZE, and several unused function prototypesRussell King2006-06-28
| | | | | | | | | | | | | | TABLE_SIZE is never used in arch/arm/mm/init.c. create_memmap_holes(), memtable_init, and setup_io_desc() no longer exist in the kernel. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * [ARM] nommu: Provide a simple flush_dcache_page implementationRussell King2006-06-28
| | | | | | | | | | | | | | | | nommu doesn't require a complex flush_dcache_page implementation like the MMU-ful CPUs do, so provide a simplified version in nommu.c and omit flush.c from the build as appropriate. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * [ARM] nommu: add arch/arm/Kconfig-nommu to Kconfig filesHyok S. Choi2006-06-28
| | | | | | | | | | | | | | | | | | Include Kconfig-nommu when MMU is not selected. (This is part of a patch from Hyok.) Signed-off-by: Hyok S. Choi <hyok.choi@samsung.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * [ARM] nommu: add stubs for ioremap and friendsRussell King2006-06-28
| | | | | | | | | | | | | | | | | | | | | | nommu doesn't have any form of remapping support, so ioremap, etc become stubs which just return the casted address, doing nothing else. Move ioport_map(), ioport_unmap(), pci_iomap(), pci_iounmap() into a separate file which is always built. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * [ARM] nommu: avoid selecting TLB and CPU specific copy codeHyok S. Choi2006-06-28
| | | | | | | | | | | | | | | | | | | | | | Since uclinux doesn't make use of the TLB, including the TLB maintainence and CPU-optimised copypage functions does not make sense. Remove them. (This is part of one of Hyok's patches.) Signed-off-by: Hyok S. Choi <hyok.choi@samsung.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * [ARM] nommu: uaccess tweaksRussell King2006-06-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MMUless systems have only one address space for all threads, so both the usual access_ok() checks, and the exception handling do not make much sense. Hence, discard the fixup and exception tables at link time, use memcpy/memset for the user copy/clearing functions, and define the permission check macros to be constants. Some of this patch was derived from the equivalent patch by Hyok S. Choi. Signed-off-by: Hyok S. Choi <hyok.choi@samsung.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * [ARM] nommu: adjust headers for !MMU ARM systemsRussell King2006-06-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Majorily based on Hyok Choi's patches, this fixes up the asm-arm header files for mmuless systems. Over and above Hyok's patches: - nommu.h merged into mmu.h (it's only a structure) - nommu_context.h is essentially the same as mmu_context.h, but without the MM switching code. so there's no point having separate files. Also, in memory.h, there's no point #ifndef'ing PHYS_OFFSET and END_MEM - both CONFIG_DRAM_BASE and CONFIG_DRAM_SIZE will always be set by the configuration scripts. Other files have minor formatting changes, but are essentially the same. Hyok's original patches were signed off thusly: Signed-off-by: Hyok S.

| * [ARM] nommu: we need the TLS register emulation for nommu modeRussell King2006-06-28
| | | | | | | | | | | | | | | | | | | | | | Since there can be no fixed location for the TLS value with nommu systems, we must provide TLS register emulation in order to support TLS binaries on CPUs without the thread register.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Guennadi Liakhovetski Currently probe_irq_on() on PXA will silently reconfigure all output GPIOs, that are not configured as alternate functions, for input. Avoid that. Upon CPU reset all GPIOs are configured as inputs, so, if a GPIO is configured as output, it has been done so intentionally. Signed-off-by: G.
