2012-08-24powerpc/perf: Use pmc_overflow() to detect rolled back eventsSukadev Bhattiprolu
For certain speculative events on Power7, 'perf stat' reports far higher event count than 'perf record' for the same event. As described in following commit, a performance monitor exception is raised even when the the performance events are rolled back. commit 0837e3242c73566fc1c0196b4ec61779c25ffc93 Author: Anton Blanchard <anton@samba.org> Date: Wed Mar 9 14:38:42 2011 +1100 perf_event_interrupt() records an event only when an overflow occurs. But this check for overflow is a simple 'if (val < 0)'. Because the events are rolled back, this check for overflow fails and the event is not recorded. perf_event_interrupt() later uses pmc_overflow() to detect the overflow and resets the counters and the events are lost completely. To properly detect the overflow of rolled back events, use pmc_overflow() even when recording events. To reproduce: $ cat strcpy.c #include <stdio.h> #include <string.h> main() { char buf[256]; alarm(5); while(1) strcpy(buf, "string1"); } $ perf record -e r20014 ./strcpy $ perf report -n > report.1 $ perf stat -e r20014 > report.2 # Compare report.1 and report.2 Reported-by: Maynard Johnson <mpjohn@us.ibm.com> Signed-off-by: Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2012-08-24powerpc: Fix personality handling in ppc64_personality()Jiri Kosina
Directly comparing current->personality against PER_LINUX32 doesn't work in cases when any of the personality flags stored in the top three bytes are used. Directly forcefully setting personality to PER_LINUX32 or PER_LINUX discards any flags stored in the top three bytes Use personality() macro to compare only PER_MASK bytes and make sure that we are setting only the bits that should be set, instead of overwriting the whole value.

2012-08-24powerpc/kgdb: Restore current_thread_info properlyTiejun Chen
For powerpc BooKE and e200, singlestep is handled on the critical/dbg exception stack. This causes current_thread_info() to fail for kgdb internal, so previously We work around this issue by copying the thread_info from the kernel stack before calling kgdb_handle_exception, and copying it back afterwards. But actually we don't do this properly. We should backup current_thread_info then restore that when exit.

2012-08-23ARM: ux500: don't select LEDS_GPIO for snowballArnd Bergmann
Using 'select' in Kconfig is hard, a platform cannot just enable a driver without also making sure that its subsystem is there. Also, there is no actual code dependency between the platform and the gpio leds driver. Without this patch, building without LEDS_CLASS esults in: drivers/built-in.o: In function `create_gpio_led.part.2': governor_userspace.c:(.devinit.text+0x5a58): undefined reference to `led_classdev_register' drivers/built-in.o: In function `gpio_led_remove': governor_userspace.c:(.devexit.text+0x6b8): undefined reference to `led_classdev_unregister' This reverts 8733f53c6 "ARM: ux500: Kconfig: Compile in leds-gpio support for Snowball" that introduced the regression and did not provide a helpful explanation. In order to leave the GPIO LED code still present in normal builds, this also enables the symbol in u8500_defconfig, in addition to the other LED drivers that are already selected there.

2012-08-23ARM: imx: build i.MX6 functions only when neededArnd Bergmann
The head-v7.S contains a call to the generic cpu_suspend function, which is only available when selected by the i.MX6 code. As pointed out by Shawn Guo, i.MX5 does not actually use any functions defined in head-v7.S. It is also needed only for the i.MX6 power management code and for the SMP code, so we can restrict building this file to situations in which at least one of those two is present. Finally, other platforms with a similar file call it headsmp.S, so we can rename it to the same for consistency. Without this patch, building imx5 standalone results in: arch/arm/mach-imx/built-in.o: In function `v7_cpu_resume': arch/arm/mach-imx/head-v7.S:104: undefined reference to `cpu_resume' Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Shawn Guo <shawn.guo@linaro.org> Cc: Eric Miao <eric.miao@linaro.org> Cc: stable@vger.kernel.org
2012-08-23ARM: imx: select CPU_FREQ_TABLE when neededArnd Bergmann
The i.MX cpufreq implementation uses the CPU_FREQ_TABLE helpers, so it needs to select that code to be built. This problem has apparently existed since the i.MX cpufreq code was first merged in v2.6.37. Building IMX without CPU_FREQ_TABLE results in: arch/arm/plat-mxc/built-in.o: In function `mxc_cpufreq_exit': arch/arm/plat-mxc/cpufreq.c:173: undefined reference to `cpufreq_frequency_table_put_attr' arch/arm/plat-mxc/built-in.o: In function `mxc_set_target': arch/arm/plat-mxc/cpufreq.c:84: undefined reference to `cpufreq_frequency_table_target' arch/arm/plat-mxc/built-in.o: In function `mxc_verify_speed': arch/arm/plat-mxc/cpufreq.c:65: undefined reference to `cpufreq_frequency_table_verify' arch/arm/plat-mxc/built-in.o: In function `mxc_cpufreq_init': arch/arm/plat-mxc/cpufreq.c:154: undefined reference to `cpufreq_frequency_table_cpuinfo' arch/arm/plat-mxc/cpufreq.c:162: undefined reference to `cpufreq_frequency_table_get_attr' Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Shawn Guo <shawn.guo@linaro.org> Cc: Sascha Hauer <s.hauer@pengutronix.de> Cc: Yong Shen <yong.shen@linaro.org> Cc: stable@vger.kernel.org
2012-08-23ARM: imx: fix ksz9021rn_phy_fixupArnd Bergmann
The ksz9021rn_phy_fixup and mx6q_sabrelite functions try to set up an ethernet phy if they can. They do check whether phylib is enabled, but unfortunately the functions can only be called from platform code if phylib is builtin, not if it is a module Without this patch, building with a modular phylib results in: arch/arm/mach-imx/mach-imx6q.c: In function 'imx6q_sabrelite_init': arch/arm/mach-imx/mach-imx6q.c:120:5: error: 'ksz9021rn_phy_fixup' undeclared (first use in this function) arch/arm/mach-imx/mach-imx6q.c:120:5: note: each undeclared identifier is reported only once for each function it appears in The bug was originally reported by Artem Bityutskiy but only partially fixed in ef441806 "ARM: imx6q: register phy fixup only when CONFIG_PHYLIB is enabled".

2012-08-23ARM: omap: allow building omap44xx without SMPArnd Bergmann
The new omap4 cpuidle implementation currently requires ARCH_NEEDS_CPU_IDLE_COUPLED, which only works on SMP. This patch makes it possible to build a non-SMP kernel for that platform. This is not normally desired for end-users but can be useful for testing. Without this patch, building rand-0y2jSKT results in: drivers/cpuidle/coupled.c: In function 'cpuidle_coupled_poke': drivers/cpuidle/coupled.c:317:3: error: implicit declaration of function '__smp_call_function_single' [-Werror=implicit-function-declaration] It's not clear if this patch is the best solution for the problem at hand. I have made sure that we can now build the kernel in all configurations, but that does not mean it will actually work on an OMAP44xx.

2012-08-23xen/setup: Fix one-off error when adding for-balloon PFNs to the P2M.Konrad Rzeszutek Wilk
When we are finished with return PFNs to the hypervisor, then populate it back, and also mark the E820 MMIO and E820 gaps as IDENTITY_FRAMEs, we then call P2M to set areas that can be used for ballooning. We were off by one, and ended up over-writting a P2M entry that most likely was an IDENTITY_FRAME. For example: 1-1 mapping on 40000->40200 1-1 mapping on bc558->bc5ac 1-1 mapping on bc5b4->bc8c5 1-1 mapping on bc8c6->bcb7c 1-1 mapping on bcd00->100000 Released 614 pages of unused memory Set 277889 page(s) to 1-1 mapping Populating 40200-40466 pfn range: 614 pages added => here we set from 40466 up to bc559 P2M tree to be INVALID_P2M_ENTRY. We should have done it up to bc558. The end result is that if anybody is trying to construct a PTE for PFN bc558 they end up with ~PAGE_PRESENT.
