[PATCH] consolidate line discipline number definitions

2007-02-11T18:51:26+00:00

The line discipline numbers N_* are currently defined for each architecture
individually, but (except for a seeming mistake) identically, in
asm/termios.h.  There is no obvious reason why these numbers should be
architecture specific, nor any apparent relationship with the termios
structure.  The total number of these, NR_LDISCS, is defined in linux/tty.h
anyway.  So I propose the following patch which moves the definitions of
the individual line disciplines to linux/tty.h too.

Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused
in the current kernel, but the patch still keeps the complete set in case
there are plans to use them yet.

[PATCH] Remove final references to deprecated "MAP_ANON" page protection flag

2007-02-11T18:51:17+00:00

Remove the last vestiges of the long-deprecated "MAP_ANON" page protection
flag: use "MAP_ANONYMOUS" instead.

[PATCH] FD_ZERO build fix

2007-01-12T02:18:22+00:00

unionfs managed to hit this on s390.  Some architectures use __ptr_t in their
FD_ZERO implementation.  We don't have a __ptr_t.  Switch them over to plain
old void*.

[PATCH] Optimize D-cache alias handling on fork

2006-12-13T17:27:08+00:00

Virtually index, physically tagged cache architectures can get away
without cache flushing when forking.  This patch adds a new cache
flushing function flush_cache_dup_mm(struct mm_struct *) which for the
moment I've implemented to do the same thing on all architectures
except on MIPS where it's a no-op.

[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] Pass struct dev pointer to dma_cache_sync()

2006-12-07T16:39:41+00:00

Pass struct dev pointer to dma_cache_sync()

dma_cache_sync() is ill-designed in that it does not have a struct device
pointer argument which makes proper support for systems that consist of a
mix of coherent and non-coherent DMA devices hard.  Change dma_cache_sync
to take a struct device pointer as first argument and fix all its callers
to pass it.

[PATCH] Add struct dev pointer to dma_is_consistent()

dma_is_consistent() is ill-designed in that it does not have a struct

of a mix of coherent and non-coherent DMA devices hard.  Change
dma_is_consistent to take a struct device pointer as first argument and fix
the sole caller to pass it.
