Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[ARM] nommu: adjust headers for !MMU ARM systems 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] ARMv6: add CPU_HAS_ASID configuration Presently, we check for the minimum ARM architecture that we're building for to determine whether we need ASID support. This is wrong - if we're going to support a range of CPUs which include ARMv6 or higher, we need the ASID. Convert the checks to use a new configuration symbol, and arrange for ARMv6 and higher CPU entries to select it. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

[ARM] Add section support to ioremap Allow section mappings to be setup using ioremap() and torn down with iounmap(). This requires additional support in the MM context switch to ensure that mappings are properly synchronised when mapped in. Based an original implementation by Deepak Saxena, reworked and ARMv6 support added by rmk. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
