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! 2005-04-17 06:20:36 +08:00			`#`

s390/uaccess: get rid of indirect function calls There are only two uaccess variants on s390 left: the version that is used if the mvcos instruction is available, and the page table walk variant. So there is no need for expensive indirect function calls. By default the mvcos variant will be called. If the mvcos instruction is not available it will call the page table walk variant. For minimal performance impact the "if (mvcos_is_available)" is implemented with a jump label, which will be a six byte nop on machines with mvcos.

s390/string: provide asm lib functions for memcpy and memcmp Our memcpy and memcmp variants were implemented by calling the corresponding gcc builtin variants. However gcc is free to replace a call to __builtin_memcmp with a call to memcmp which, when called, will result in an endless recursion within memcmp. So let's provide asm variants and also fix the variants that are used for uncompressing the kernel image. In addition remove all other occurences of builtin function calls.

[PATCH] s390: Remove CVS generated information - Remove all CVS generated information like e.g. revision IDs from drivers/s390 and include/asm-s390 (none present in arch/s390). - Add newline at end of arch/s390/lib/Makefile to avoid diff message.
