2007-05-17[POWERPC] Fix ppc_rtas_progress_show()Segher Boessenkool
Fixes the warning arch/powerpc/kernel/rtas-proc.c: In function 'ppc_rtas_progress_show': arch/powerpc/kernel/rtas-proc.c:382: warning: the address of 'progress_led' will always evaluate as 'true' by fixing the code to do what it presumably is meant to do.

2007-02-12[PATCH] mark struct file_operations const 2Arjan van de Ven
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2006-07-31[POWERPC] Constify & voidify get_property()Jeremy Kerr
Now that get_property() returns a void *, there's no need to cast its return value. Also, treat the return value as const, so we can constify get_property later. powerpc core changes. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

2006-03-28[PATCH] powerpc: Kill _machine and hard-coded platform numbersBenjamin Herrenschmidt
This removes statically assigned platform numbers and reworks the powerpc platform probe code to use a better mechanism. With this, board support files can simply declare a new machine type with a macro, and implement a probe() function that uses the flattened device-tree to detect if they apply for a given machine. We now have a machine_is() macro that replaces the comparisons of _machine with the various PLATFORM_* constants. This commit also changes various drivers to use the new macro instead of looking at _machine.

2006-02-10[PATCH] powerpc: trivial: modify comments to refer to new location of filesJon Mason
This patch removes all self references and fixes references to files in the now defunct arch/ppc64 tree. I think this accomplises everything wanted, though there might be a few references I missed. Signed-off-by: Jon Mason <jdmason@us.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-11[PATCH] powerpc: Merge vdso's and add vdso support to 32 bits kernelBenjamin Herrenschmidt
This patch moves the vdso's to arch/powerpc, adds support for the 32 bits vdso to the 32 bits kernel, rename systemcfg (finally !), and adds some new (still untested) routines to both vdso's: clock_gettime() with support for CLOCK_REALTIME and CLOCK_MONOTONIC, clock_getres() (same clocks) and get_tbfreq() for glibc to retreive the timebase frequency. Tom,Steve: The implementation of get_tbfreq() I've done for 32 bits returns a long long (r3, r4) not a long. This is such that if we ever add support for >4Ghz timebases on ppc32, the userland interface won't have to change. I have tested gettimeofday() using some glibc patches in both ppc32 and ppc64 kernels using 32 bits userland (I haven't had a chance to test a 64 bits userland yet, but the implementation didn't change and was tested earlier). I haven't tested yet the new functions. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-10[PATCH] powerpc: merge code values for identifying platformsPaul Mackerras
This patch merges platform codes. systemcfg->platform is no longer used, systemcfg use in general is deprecated as much as possible (and renamed _systemcfg before it gets completely moved elsewhere in a future patch), _machine is now used on ppc64 along as ppc32. Platform codes aren't gone yet but we are getting a step closer. A bunch of asm code in head[_64].S is also turned into C code.

2005-11-03powerpc: Merge remaining RTAS codePaul Mackerras
This moves rtas-proc.c and rtas_flash.c into arch/powerpc/kernel, since cell wants them as well as pseries (and chrp can use rtas-proc.c too, at least in principle). rtas_fw.c is gone, with its bits moved into rtas_flash.c and rtas.c. Signed-off-by: Paul Mackerras <paulus@samba.org>
