2006-06-28[ARM] nommu: backtrace code must not reference a discarded sectionRussell King
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>
2006-06-28[ARM] nommu: Initial uCLinux support for MMU-based CPUsHyok S. Choi
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.

2006-06-28[ARM] nommu: prevent Xscale-based machines being selectedRussell King
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.

2006-06-28[ARM] nommu: export flush_dcache_page()Hyok S. Choi
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>
2006-06-28[ARM] nommu: remove fault-armv, mmap and mm-armv files from nommu buildRussell King
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>
2006-06-28[ARM] Remove TABLE_SIZE, and several unused function prototypesRussell King
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>
2006-06-28[ARM] nommu: Provide a simple flush_dcache_page implementationRussell King
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>
2006-06-28[ARM] nommu: add arch/arm/Kconfig-nommu to Kconfig filesHyok S. Choi
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>
2006-06-28[ARM] nommu: add stubs for ioremap and friendsRussell King
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>
2006-06-28[ARM] nommu: avoid selecting TLB and CPU specific copy codeHyok S. Choi
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>
2006-06-28[ARM] nommu: uaccess tweaksRussell King
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>
2006-06-28[ARM] nommu: adjust headers for !MMU ARM systemsRussell King
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.

2006-06-28[ARM] nommu: we need the TLS register emulation for nommu modeRussell King
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. Part of a patch from Hyok S. Choi, and cleaned up by rmk. Signed-off-by: Hyok S. Choi <hyok.choi@samsung.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-06-28[ARM] Remove the __arch_* layer from uaccess.hRussell King
Back in the days when we had armo (26-bit) and armv (32-bit) combined, we had an additional layer to the uaccess macros to ensure correct typing. Since we no longer have 26-bit in this tree, we no longer need this layer, so eliminate it. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2006-06-27[PATCH] i2c-i801.c: don't pci_disable_device() after it was just enabledDaniel Ritz
Commit 02dd7ae2892e5ceff111d032769c78d3377df970 ("[PATCH] i2c-i801: Merge setup function") has a missing return 0 in the _probe() function. This means the error path is always executed and pci_disable_device() is called even when the device just got successfully enabled. Having the SMBus device disabled makes some systems (eg. Fujitsu-Siemens Lifebook E8010) hang hard during power-off. Intead of reverting the whole commit this patch fixes it up: - don't ever call pci_disable_device(), also not in the _remove() function to avoid hangs - fix missing pci_release_region() in error path Signed-off-by: Daniel Ritz <daniel.ritz@gmx.ch> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-06-27[PATCH] m68knommu: remove useless compiler argsPhilipe De Muyter
Here is a small patch that made my kernel .text segment shrink by 8k IIRC on my 5272-based board, by removing `-Wa,-S' from CFLAGS. The `-Wa,-S' option prevents `gas' from using short forms of jsr. Without it, `gas' replaces `jsr xxx.l' (6 bytes) by `jsr xxx@pc' (4 bytes) when possible. On 5272, both forms are equally fast. The `-Wa,-m5307' option is useless, because gcc already gives it to `gas' from the `-m5307' option. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
