powerpc: Create DOTSYM to wrap dot symbol usage

2014-04-23T00:05:19+00:00

There are a few places we have to use dot symbols with the
current ABI - the syscall table and the kvm hcall table.

Wrap both of these with a new macro called DOTSYM so it will
be easy to transition away from dot symbols in a future ABI.

powerpc: Don't use a function descriptor for system call table

2014-04-23T00:05:17+00:00

There is no need to create a function descriptor for the system call
table. By using one we force the system call table into the text
section and it really belongs in the rodata section.

This also removes another use of dot symbols.

[POWERPC] Align the sys_call_table

2007-10-11T04:36:47+00:00

Our _GLOBAL macro does a ".align 2" so the alignment is fine for 32
bit, but on 64 bit it is possible for it to end up only 4 byte aligned.
I don't know if it matters, but it can't hurt to 8 byte align it.

It also means that when we build with --emit_relocs, none of our 64 bit
relocations are to misaligned places.

[POWERPC] Unify ppc syscall tables

2006-06-21T05:01:32+00:00

Avoid duplication of the syscall table for the cell platform.  Based on an
idea from David Woodhouse.

[PATCH] powerpc: Wire up *at syscalls

2006-04-28T11:04:59+00:00

Wire up *at syscalls.

This patch has been tested on ppc64 (using glibc's testsuite, both 32bit
and 64bit), and compile-tested for ppc32 (I have currently no ppc32 system
available, but I expect no problems).

[PATCH] Add support for the sys_vmsplice syscall

2006-04-26T08:59:21+00:00

sys_splice() moves data to/from pipes with a file input/output. sys_vmsplice()
moves data to a pipe, with the input being a user address range instead.

This uses an approach suggested by Linus, where we can hold partial ranges
inside the pages[] map. Hopefully this will be useful for network
receive support as well.

[PATCH] powerpc/cell: remove BUILD_BUG_ON and add sys_tee to spu_syscall_table

2006-04-21T12:32:50+00:00

Every time a new syscall gets added, a BUILD_BUG_ON in
arch/powerpc/platforms/cell/spu_callbacks.c gets triggered.
Since the addition of a new syscall is rather harmless,
the error should just be removed.

While we're here, add sys_tee to the list and add a comment
to systbl.S to remind people that there is another list
on powerpc.

[PATCH] splice: add support for sys_tee()

2006-04-11T13:51:17+00:00

Basically an in-kernel implementation of tee, which uses splice and the
pipe buffers as an intelligent way to pass data around by reference.

Where the user space tee consumes the input and produces a stdout and
file output, this syscall merely duplicates the data inside a pipe to
another pipe. No data is copied, the output just grabs a reference to the
input pipe data.
