mips: replace #include <asm/export.h> with #include <linux/export.h> Commit ddb5cdbafaaa ("kbuild: generate KSYMTAB entries by modpost") deprecated <asm/export.h>, which is now a wrapper of <linux/export.h>. Replace #include <asm/export.h> with #include <linux/export.h>. After all the <asm/export.h> lines are converted, <asm/export.h> and <asm-generic/export.h> will be removed.

MIPS: Remove get_fs/set_fs All get_fs/set_fs calls in MIPS code are gone, so remove implementation of it. With the clear separation of user/kernel space access we no longer need the EVA special handling, so get rid of that, too.

MIPS: Fix modversions kernelci.org reports tons of build warnings for linux-next: 35 WARNING: "memcpy" [fs/fat/msdos.ko] has no CRC! 35 WARNING: "__copy_user" [fs/fat/fat.ko] has no CRC! 32 WARNING: EXPORT symbol "memset" [vmlinux] version generation failed, symbol will not be versioned. 32 WARNING: EXPORT symbol "copy_page" [vmlinux] version generation failed, symbol will not be versioned. 32 WARNING: EXPORT symbol "clear_page" [vmlinux] version generation failed, symbol will not be versioned. 32 WARNING: EXPORT symbol "__strncpy_from_user_nocheck_asm" [vmlinux] version generation failed, symbol will not be versioned. The problem here is mainly the missing asm/asm-prototypes.h header file that is supposed to include the prototypes for each symbol that is exported from an assembler file. A second problem is that the asm/uaccess.h header contains some but not all the necessary declarations for the user access helpers. Finally, the vdso build is broken once we add asm/asm-prototypes.h, so we have to fix this at the same time by changing the vdso header. My approach here is to just not look for exported symbols in the VDSO assembler files, as the symbols cannot be exported anyway.

MIPS: strnlen_user.S: Fix a CPU_DADDI_WORKAROUNDS regression Correct a regression introduced with 8453eebd [MIPS: Fix strnlen_user() return value in case of overlong strings.] causing assembler warnings and broken code generated in __strnlen_kernel_nocheck_asm: arch/mips/lib/strnlen_user.S: Assembler messages: arch/mips/lib/strnlen_user.S:64: Warning: Macro instruction expanded into multiple instructions in a branch delay slot with the CPU_DADDI_WORKAROUNDS option set, resulting in the function looping indefinitely upon mounting NFS root. Use conditional assembly to avoid a microMIPS code size regression. Using $at unconditionally would cause such a regression as there are no 16-bit instruction encodings available for ALU operations using this register. Using $v1 unconditionally would produce short microMIPS encodings, but would prevent this register from being used across calls to this function. The extra LI operation introduced is free, replacing a NOP originally scheduled into the delay slot of the branch that follows. Signed-off-by: Maciej W.

MIPS: Fix strnlen_user() return value in case of overlong strings. We were returning maxlen like the userland strnlen if no '\0' character was encountered while the kernel version is expected to return a value larger than maxlen. Fixed to return maxlen + 1.

[MIPS] Eleminate local symbols from the symbol table. These symbols appear in oprofile output, stacktraces and similar but only make the output harder to read. Many identical symbol names such as "both_aligned" were also being used in multiple source files making it impossible to see which file actually was meant. So let's get rid of them.

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!
