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: remove indirection of asm/mach-types.h Arrange for mach-types.h to be directly generated in the relevant path, so we don't need a one-liner file in arch/arm/include/asm/. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>

ARM: convert to generated system call tables Convert ARM to use a similar mechanism to x86 to generate the unistd.h system call numbers and the various kernel system call tables. This means that rather than having to edit three places (asm/unistd.h for the total number of system calls, uapi/asm/unistd.h for the system call numbers, and arch/arm/kernel/calls.S for the call table) we have only one place to edit, making the process much more simple. The scripts have knowledge of the table padding requirements, so there's no need to worry about __NR_syscalls not fitting within the immediate constant field of ALU instructions anymore.
