Several implementations were essentialy a common piece of C code using the cmpxchg() macro. Put the implementation in one spot that everyone can share, and convert sparc64 over to using this. Alpha is the lone arch-specific implementation, which codes up a special fast path for the common case in order to avoid GP reloading which a pure C version would require. Signed-off-by: David S.

Qemu is a software emulator which among other architectures also
|
|
can simulate a MIPS32 4Kc system. This patch adds support for the
|
|
system architecture that currently is being simulated by Qemu. It
|
|
will eventually be removed again when Qemu has the capability to
|
|
simulate actual MIPS hardware platforms. More information on Qemu

can be found at http://www.linux-mips.org/wiki/Qemu.

The Extended Industry Standard Architecture (EISA) bus was
|
|
developed as an open alternative to the IBM MicroChannel bus.
|
|
|
|
The EISA bus provided some of the features of the IBM MicroChannel
|
|
bus while maintaining backward compatibility with cards made for
|
|
the older ISA bus. The EISA bus saw limited use between 1988 and
|
|
1995 when it was made obsolete by the PCI bus.
|
|
|
|
Say Y here if you are building a kernel for an EISA-based machine.
|
|
|
|
Otherwise, say N.

|
A 64-bit kernel is usually built using the 64-bit ELF binary object
|
|
format as it's one that allows arbitrary 64-bit constructs. For
|
|
kernels that are loaded within the KSEG compatibility segments the
|
|
32-bit ELF format can optionally be used resulting in a somewhat
|
|
smaller binary, but this option is not explicitly supported by the
|
|
toolchain and since binutils 2.14 it does not even work at all.
|
|
|
|
Say Y to use the 64-bit format or N to use the 32-bit one.
|
|
|
|
If unsure say Y.
