powerpc: various straight conversions from module.h --> export.h All these files were including module.h just for the basic EXPORT_SYMBOL infrastructure. We can shift them off to the export.h header which is a way smaller footprint and thus realize some compile time gains. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

[PATCH] powerpc: Merge signal.h Having already merged the ppc and ppc64 versions of signal.c, this patch finishes the job by merging signal.h. The two versions were almost identical already. Notable changes: - We use BITS_PER_LONG to correctly size sigset_t - Remove some uneeded #includes and struct forward declarations. This does mean adding an include to signal_32.c which relied on the indirect inclusion of sigcontext.h - As the ppc64 version, the merged signal.h has prototypes for do_signal() and do_signal32(). Thus remove extra prototypes from ppc_ksyms.c which had them directly. Built and booted on POWER5 LPAR (ARCH=ppc64 and ARCH=powerpc). Built for 32-bit powermac (ARCH=ppc and ARCH=powerpc) and Walnut (ARCH=ppc). Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>

[POWERPC] Add __ucmpdi2 for 64-bit comparisons in 32-bit kernels Some drivers (such as V4L2) have code that causes gcc to generate calls to __ucmpdi2 when compiling for 32-bit powerpc, which results in either a link-time error or a module that can't be loaded, as we don't currently have a __ucmpdi2. This adds one so these drivers can be used. Signed-off-by: Paul Mackerras <paulus@samba.org>

[POWERPC] Only export __mtdcr/__mfdcr if CONFIG_PPC_DCR is set On 85xx we don't build in dcr support because the core doesn't implement the instructions. This caused problems when building an 85xx kernel. Additionally made it so we only build __mtdcr/__mfdcr if we are CONFIG_PPC_DCR_NATIVE. The 85xx build issue wasPointed out by Dai Haruki.

powerpc: Add support for popcnt instructions POWER5 added popcntb, and POWER7 added popcntw and popcntd. As a first step this patch does all the work out of line, but it would be nice to implement them as inlines with an out of line fallback. The performance issue with hweight was noticed when disabling SMT on a large (192 thread) POWER7 box. The patch improves that testcase by about 8%.
