Fast sleep is one of the deep idle states on Power8 in which local timers of CPUs stop. On PowerPC we do not have an external clock device which can handle wakeup of such CPUs.

It wasn't selecting CONFIG_MEMORY. So we never built drivers/memory/fsl_ifc.o and so we have nothing to link the above symbols against. Since the goal of the original commit was to relocate the driver to an arch independent location, it only makes sense to relocate the Kconfig setting there as well. But that alone won't fix the build failure; for that we ensure whoever selects FSL_IFC also selects MEMORY.

This commit adds the architecture support required to enable the optimised implementation of lockrefs. That's as simple as defining arch_spin_value_unlocked() and selecting the Kconfig option. We also define cmpxchg64_relaxed(), because the lockref code does not need the cmpxchg to have barrier semantics. Using Linus' test case[1] on one system I see a 4x improvement for the basic enablement, and a further 1.3x for cmpxchg64_relaxed(), for a total of 5.3x vs the baseline. On another system I see more like 2x improvement.

the setup before the change was - arch/powerpc/Kconfig had the PPC_CLOCK option, off by default - depending on the PPC_CLOCK option the arch/powerpc/kernel/clock.c file was built, which implements the clk.h API but always returns -ENOSYS unless a platform registers specific callbacks - the MPC52xx platform selected PPC_CLOCK but did not register any callbacks, thus all clk.h API calls keep resulting in -ENOSYS errors (which is OK, all peripheral drivers deal with the situation) - the MPC512x platform selected PPC_CLOCK and registered specific callbacks implemented in arch/powerpc/platforms/512x/clock.c, thus provided real support for the clock API - no other powerpc platform did select PPC_CLOCK the situation after the change is - the MPC512x platform implements the COMMON_CLK interface, and thus the PPC_CLOCK approach in arch/powerpc/platforms/512x/clock.c has become obsolete - the MPC52xx platform still lacks genuine support for the clk.h API while this is not a change against the previous situation (the error code returned from COMMON_CLK stubs differs but every call still results in an error) - with all references gone, the arch/powerpc/kernel/clock.c wrapper and the PPC_CLOCK option have become obsolete, as did the clk_interface.h header file the switch from PPC_CLOCK to COMMON_CLK is done for all platforms within the same commit such that multiplatform kernels (the combination of 512x and 52xx within one executable) keep working Cc: Mike Turquette <mturquette@linaro.org> Cc: Anatolij Gustschin <agust@denx.de> Cc: linux-arm-kernel@lists.infradead.org Cc: linuxppc-dev@lists.ozlabs.org Signed-off-by: NGerhard Sittig <gsi@denx.de> Signed-off-by: NAnatolij Gustschin <agust@denx.de>

On 64-bit, __pa(&static_var) gets miscompiled by recent versions of gcc as something like: addis 3,2,.LANCHOR1+4611686018427387904@toc@ha addi 3,3,.LANCHOR1+4611686018427387904@toc@l This ends up effectively ignoring the offset, since its bottom 32 bits are zero, and means that the result of __pa() still has 0xC in the top nibble. This happens with gcc 4.8.1, at least. To work around this, for 64-bit we make __pa() use an AND operator, and for symmetry, we make __va() use an OR operator. Using an AND operator rather than a subtraction ends up with slightly shorter code since it can be done with a single clrldi instruction, whereas it takes three instructions to form the constant (-PAGE_OFFSET) and add it on. (Note that MEMORY_START is always 0 on 64-bit.) CC: <stable@vger.kernel.org> Signed-off-by: NPaul Mackerras <paulus@samba.org> Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

For some SoC (such as the FSL BookE) even though there does have a hardware FPU, but not all floating point instructions are implemented. Unfortunately some versions of gcc do use these unimplemented instructions. Then we have to enable the math emulation to workaround this issue. It seems a little redundant to have the support to emulate all the floating point instructions in this case. So split the math emulation into two parts. One is for the SoC which doesn't have FPU at all and the other for the SoC which does have the hardware FPU and only need some special floating point instructions to be emulated.

This is duplicated code from math-emu and implements such a small subset of the FPU (load/stores/fmr) that it's essentially pointless nowdays. Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

(Including 64-bit ones) This allow SW emulation by the kernel of optional instructions such as fsqrt which aren't implemented on some processors, and thus fixes some Fedora 19 issues such as Anaconda since the compiler is set to generate those by default on 64-bit.

Ever since commit 45f035ab ("CONFIG_HOTPLUG should be always on"), it has been basically impossible to build a kernel with CONFIG_HOTPLUG turned off. Remove all the remaining references to it.

This patch removes the Kconfig symbol HAVE_CAN_FLEXCAN from arch/{arm,powerpc} and allowing compilation unconditionally on all arm and powerpc platforms. This brings a bigger compile time coverage and removes the following dependency warning found by Arnd Bergmann: warning: (SOC_IMX28 && SOC_IMX25 && SOC_IMX35 && IMX_HAVE_PLATFORM_FLEXCAN && SOC_IMX53 && SOC_IMX6Q) selects HAVE_CAN_FLEXCAN which has unmet direct dependencies (NET && CAN && CAN_DEV) Acked-by: NArnd Bergmann <arnd@arndb.de> Acked-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org> Acked-by: NShawn Guo <shawn.guo@linaro.org> Signed-off-by: NMarc Kleine-Budde <mkl@pengutronix.de>

The Kconfig symbol MAX_ACTIVE_REGIONS is unused. Commit 0ee332c1 ("memblock: Kill early_node_map[]") removed the only place were it was actually used. But it did not remove its Kconfig entries (for powerpc and sh). Remove those two entries (and the entry for metag, that popped up in v3.9-rc1).
