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!

MIPS: asm: Add wrappers for EVA/non-EVA instructions EVA uses specific instructions for accessing user memory. Instead of polluting the kernel with numerous #ifdef CONFIG_EVA we add wrappers for all the instructions that need special handling when EVA is enabled.

MIPS: properly stop .eh_frame generation Commit 866b6a89c6d1 ("MIPS: Add DWARF unwinding to assembly") added -fno-asynchronous-unwind-tables to KBUILD_CFLAGS to prevent compiler from emitting .eh_frame symbols. However, as MIPS heavily uses CFI, that's not enough. Use the approach taken for x86 (as it also uses CFI) and explicitly put CFI symbols into the .debug_frame section (except for VDSO). This allows us to drop .eh_frame from DISCARDS as it's no longer being generated.

MIPS: End asm function prologue macros with .insn When building a kernel targeting a microMIPS ISA, recent GNU linkers will fail the link if they cannot determine that the target of a branch or jump is microMIPS code, with errors such as the following: mips-img-linux-gnu-ld: arch/mips/built-in.o: .text+0x542c: Unsupported jump between ISA modes; consider recompiling with interlinking enabled. mips-img-linux-gnu-ld: final link failed: Bad value or: ./arch/mips/include/asm/uaccess.h:1017: warning: JALX to a non-word-aligned address Placing anything other than an instruction at the start of a function written in assembly appears to trigger such errors. In order to prepare for allowing us to follow function prologue macros with an EXPORT_SYMBOL invocation, end the prologue macros (LEAD, NESTED & FEXPORT) with a .insn directive. This ensures that the start of the function is marked as code, which always makes sense for functions & safely prevents us from hitting the link errors described above.

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.

MIPS: Workaround clang inline compat branch issue Clang is unable to handle the situation that a chunk of inline assembly ends with a compat branch instruction and then compiler generates another control transfer instruction immediately after this compat branch. The later instruction will end up in forbidden slot and cause exception. Workaround by add a option to control the use of compact branch. Currently it's selected by CC_IS_CLANG and hopefully we can change it to a version check in future if clang manages to fix it. Fix boot on boston board.
