[PATCH] Xtensa: Add ktermios and minor filename fix

2006-12-13T17:05:50+00:00

The kernel termios (ktermios) changes were somehow missed for Xtensa.  This
patch adds the ktermios structure and also includes some minor file name
fix that was missed in the syscall patch.

[PATCH] xtensa: fix system call interface

2006-12-10T17:55:39+00:00

This is a long outstanding patch to finally fix the syscall interface.  The
constants used for the system calls are those we have provided in our libc
patches.  This patch also fixes the shmbuf and stat structure, and fcntl
definitions.

[PATCH] xtensa: remove extra header files

2006-12-10T17:55:39+00:00

The Xtensa port contained many header files that were never needed.  This
rather lengthy patch removes all those files.  Unfortunately, there were
many dependencies that needed to be updated, so this patch touches quite a
few source files.

[PATCH] xtensa: fix irq and misc fixes

2006-12-10T17:55:39+00:00

Update the architecture specific interrupt handling code for Xtensa to support
the new API.  Use generic BUG macros in bug.h, and some minor fixes.

[PATCH] LOG2: Implement a general integer log2 facility in the kernel

2006-12-08T16:28:51+00:00

This facility provides three entry points:

	ilog2()		Log base 2 of unsigned long
	ilog2_u32()	Log base 2 of u32
	ilog2_u64()	Log base 2 of u64

These facilities can either be used inside functions on dynamic data:

	int do_something(long q)
	{
		...;
		y = ilog2(x)
		...;
	}

Or can be used to statically initialise global variables with constant values:

	unsigned n = ilog2(27);

When performing static initialisation, the compiler will report "error:
initializer element is not constant" if asked to take a log of zero or of
something not reducible to a constant.  They treat negative numbers as
unsigned.

When not dealing with a constant, they fall back to using fls() which permits
them to use arch-specific log calculation instructions - such as BSR on
x86/x86_64 or SCAN on FRV - if available.

[PATCH] vmlinux.lds: consolidate initcall sections

2006-10-27T22:34:51+00:00

Add a vmlinux.lds.h helper macro for defining the eight-level initcall table,
teach all the architectures to use it.

This is a prerequisite for a patch which performs initcall synchronisation for
multithreaded-probing.

Attack of "the the"s in arch

2006-10-03T20:21:02+00:00

The patch below corrects multiple occurances of "the the"
typos across several files, both in source comments and KConfig files.
There is no actual code changed, only text.  Note this only affects the /arch
directory, and I believe I could find many more elsewhere. :)

[PATCH] provide kernel_execve on all architectures

2006-10-02T14:57:23+00:00

This adds the new kernel_execve function on all architectures that were using
_syscall3() to implement execve.

The implementation uses code from the _syscall3 macros provided in the
unistd.h header file.  I don't have cross-compilers for any of these
architectures, so the patch is untested with the exception of i386.

Most architectures can probably implement this in a nicer way in assembly or
by combining it with the sys_execve implementation itself, but this should do
it for now.
