Michael Ellerman c59acae854 [POWERPC] iseries: Make ItExtVpdPanel private to iSeries
No one outside platforms/iseries needs ItExtVpdPanel anymore, so move
it in there. It used to be needed by lparcfg, and so was exported, but
isn't needed anymore, so unexport it.

Stephen Rothwell 16e9f99444 [POWERPC] Make lparcfg.c work when both iseries and pseries are selected
This also consolidates the initial bits of lparcfg_data() and adds the
partition number to the iSeries flattened device tree.

jimix@watson.ibm.com 8ae5b2801a [PATCH] powerpc: udbg_printf() formatting attribute
This patch allows the compiler to catch any printf-like mismatches for
udbg_printf().  After some brute force building I've only found issues
with my own code and lparcfg.c It could break some developers, but
IMHO that would be goodness.

Will Schmidt 34422fed65 [PATCH] powerpc/pseries: misc lparcfg fixes
This fixes several problems with the lparcfg code.  In case
someone gets a sense of deja-vu, part of this was submitted last Sep, I
thought the changes went in, but either got backed out, or just got
lost.

First, change the local_buffer declaration to be unsigned char *.  We
had a bad-math problem in a 2.4 tree which was built with a
"-fsigned-char" parm.  I dont believe we ever build with that parm
now-a-days, but to be safe, I'd prefer the declaration be explicit.

Second, fix a bad math calculation for splpar_strlen.

Third, on the rtas_call for get-system-parameter, pass in
RTAS_DATA_BUF_SIZE for the rtas_data_buf size, instead of letting random
data determine the size.   Until recently, we've had a sufficiently
large 'random data' value get passed in, so the function just happens to
have worked OK.   Now it's getting passed a '0', which causes the
rtas_call to return success, but no data shows up in the buffer.
(oops!).   This was found by the LTC test org.

This is in a branch of code that only gets run on SPLPAR systems.
Tested on power5 Lpar.

KAMEZAWA Hiroyuki 0e5519548f [PATCH] for_each_possible_cpu: powerpc
for_each_cpu() actually iterates across all possible CPUs.  We've had mistakes
in the past where people were using for_each_cpu() where they should have been
iterating across only online or present CPUs.  This is inefficient and
possibly buggy.

We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the
future.

This patch replaces for_each_cpu with for_each_possible_cpu.

David Gibson 3356bb9f7b [PATCH] powerpc: Remove lppaca structure from the PACA
At present the lppaca - the structure shared with the iSeries
hypervisor and phyp - is contained within the PACA, our own low-level
per-cpu structure.  This doesn't have to be so, the patch below
removes it, making a separate array of lppaca structures.

This saves approximately 500*NR_CPUS bytes of image size and kernel
memory, because we don't need aligning gap between the Linux and
hypervisor portions of every PACA.  On the other hand it means an
extra level of dereference in many accesses to the lppaca.

The patch also gets rid of several places where we assign the paca
address to a local variable for no particular reason.

Anton Blanchard 8acb888c9c [PATCH] ppc64: Quieten lparcfg
If we dont have permission to read some information from the hypervisor,
lparcfg outputs a warning on the console. Now that lparcfg is world
readable this is a problem.

Dont warn in the case of H_Authority, remove some unnecessary function
prototypes and fix whitespace damage in a structure as well.

David Gibson d3d2176a0b [PATCH] powerpc: Move more ppc64 files with no ppc32 equivalent to powerpc
This patch moves a bunch more files from arch/ppc64 and
include/asm-ppc64 which have no equivalents in ppc32 code into
arch/powerpc and include/asm-powerpc.  The file affected are:
	hvcall.h
	proc_ppc64.c
	sysfs.c
	lparcfg.c
	rtas_pci.c

The only changes apart from the move and corresponding Makefile
changes are:
	- #ifndef/#define in includes updated to _ASM_POWERPC_ form
	- trailing whitespace removed
	- comments giving full paths removed

Built and booted on POWER5 LPAR (ARCH=powerpc and ARCH=ppc64), built
for 32-bit powermac (ARCH=powerpc).
