[PATCH] powerpc: Restore CONFIG_DEBUG_INFO in defconfigs

by Christophe Leroy

Commit f9b3cd245784 ("Kconfig.debug: make DEBUG_INFO selectable from a choice") broke the selection of CONFIG_DEBUG_INFO by powerpc defconfigs. It is now necessary to select one of the three DEBUG_INFO_DWARF* options to get DEBUG_INFO enabled. Replace DEBUG_INFO=y by DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT=y in all defconfigs using the following command: sed -i s/DEBUG_INFO=y/DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT=y/g `git grep -l DEBUG_INFO arch/powerpc/configs/` Fixes: f9b3cd245784 ("Kconfig.debug: make DEBUG_INFO selectable from a choice") Cc: stable(a)vger.kernel.org Cc: Kees Cook <keescook(a)chromium.org> Signed-off-by: Christophe Leroy <christophe.leroy(a)csgroup.eu> --- arch/powerpc/configs/44x/akebono_defconfig | 2 +- arch/powerpc/configs/44x/currituck_defconfig | 2 +- arch/powerpc/configs/44x/fsp2_defconfig | 2 +- arch/powerpc/configs/44x/iss476-smp_defconfig | 2 +- arch/powerpc/configs/44x/warp_defconfig | 2 +- arch/powerpc/configs/52xx/lite5200b_defconfig | 2 +- arch/powerpc/configs/52xx/motionpro_defconfig | 2 +- arch/powerpc/configs/52xx/tqm5200_defconfig | 2 +- arch/powerpc/configs/adder875_defconfig | 2 +- arch/powerpc/configs/ep8248e_defconfig | 2 +- arch/powerpc/configs/ep88xc_defconfig | 2 +- arch/powerpc/configs/fsl-emb-nonhw.config | 2 +- arch/powerpc/configs/mgcoge_defconfig | 2 +- arch/powerpc/configs/mpc5200_defconfig | 2 +- arch/powerpc/configs/mpc8272_ads_defconfig | 2 +- arch/powerpc/configs/mpc885_ads_defconfig | 2 +- arch/powerpc/configs/ppc6xx_defconfig | 2 +- arch/powerpc/configs/pq2fads_defconfig | 2 +- arch/powerpc/configs/ps3_defconfig | 2 +- arch/powerpc/configs/tqm8xx_defconfig | 2 +- 20 files changed, 20 insertions(+), 20 deletions(-) diff --git a/arch/powerpc/configs/44x/akebono_defconfig b/arch/powerpc/configs/44x/akebono_defconfig index 4bc549c6edc5..fde4824f235e 100644 --- a/arch/powerpc/configs/44x/akebono_defconfig +++ b/arch/powerpc/configs/44x/akebono_defconfig @@ -118,7 +118,7 @@ CONFIG_CRAMFS=y CONFIG_NLS_DEFAULT="n" CONFIG_NLS_CODEPAGE_437=y CONFIG_NLS_ISO8859_1=y -CONFIG_DEBUG_INFO=y +CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT=y CONFIG_MAGIC_SYSRQ=y CONFIG_DETECT_HUNG_TASK=y CONFIG_XMON=y diff --git a/arch/powerpc/configs/44x/currituck_defconfig b/arch/powerpc/configs/44x/currituck_defconfig index 717827219921..7283b7d4a1a5 100644 --- a/arch/powerpc/configs/44x/currituck_defconfig +++ b/arch/powerpc/configs/44x/currituck_defconfig @@ -73,7 +73,7 @@ CONFIG_NFS_FS=y CONFIG_NFS_V3_ACL=y CONFIG_NFS_V4=y CONFIG_NLS_DEFAULT="n" -CONFIG_DEBUG_INFO=y +CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT=y CONFIG_MAGIC_SYSRQ=y CONFIG_DETECT_HUNG_TASK=y CONFIG_XMON=y diff --git a/arch/powerpc/configs/44x/fsp2_defconfig b/arch/powerpc/configs/44x/fsp2_defconfig index 8da316e61a08..3fdfbb29b854 100644 --- a/arch/powerpc/configs/44x/fsp2_defconfig +++ b/arch/powerpc/configs/44x/fsp2_defconfig @@ -110,7 +110,7 @@ CONFIG_XZ_DEC=y CONFIG_PRINTK_TIME=y CONFIG_MESSAGE_LOGLEVEL_DEFAULT=3 CONFIG_DYNAMIC_DEBUG=y -CONFIG_DEBUG_INFO=y +CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT=y CONFIG_MAGIC_SYSRQ=y CONFIG_DETECT_HUNG_TASK=y CONFIG_CRYPTO_CBC=y diff --git a/arch/powerpc/configs/44x/iss476-smp_defconfig b/arch/powerpc/configs/44x/iss476-smp_defconfig index c11e777b2f3d..0f6380e1e612 100644 --- a/arch/powerpc/configs/44x/iss476-smp_defconfig +++ b/arch/powerpc/configs/44x/iss476-smp_defconfig @@ -56,7 +56,7 @@ CONFIG_PROC_KCORE=y CONFIG_TMPFS=y CONFIG_CRAMFS=y #

[PATCH 5/6] drm/i915/gt: Serialize GRDOM access between multiple engine resets

by Mauro Carvalho Chehab

From: Chris Wilson <chris.p.wilson(a)intel.com> Don't allow two engines to be reset in parallel, as they would both try to select a reset bit (and send requests to common registers) and wait on that register, at the same time. Serialize control of the reset requests/acks using the uncore->lock, which will also ensure that no other GT state changes at the same time as the actual reset.

[PATCH] dmaengine: imx-sdma: only restart cyclic channel when enabled

by Sascha Hauer

An interrupt for a channel might be pending even after struct dma_device::device_terminate_all has been called. In that case the recently introduced warning message "restart cyclic channel..." triggers and the channel will be restarted. This is not desired as the channel has just been stopped. Only restart the channel when we still have a descriptor set for it (which will be set to NULL in sdma_terminate_all()). Fixes: 5b215c28b9235 ("dmaengine: imx-sdma: restart cyclic channel if needed") Cc: stable(a)vger.kernel.org Signed-off-by: Sascha Hauer <s.hauer(a)pengutronix.de> --- drivers/dma/imx-sdma.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/dma/imx-sdma.c b/drivers/dma/imx-sdma.c index 8535018ee7a2e..5356cce41bffc 100644 --- a/drivers/dma/imx-sdma.c +++ b/drivers/dma/imx-sdma.c @@ -891,7 +891,7 @@ static void sdma_update_channel_loop(struct sdma_channel *sdmac) * SDMA stops cyclic channel when DMA request triggers a channel and no SDMA * owned buffer is available (i.e. BD_DONE was set too late). */ - if (!is_sdma_channel_enabled(sdmac->sdma, sdmac->channel)) { + if (sdmac->desc && !is_sdma_channel_enabled(sdmac->sdma, sdmac->channel)) { dev_warn(sdmac->sdma->dev, "restart cyclic channel %d\n", sdmac->channel); sdma_enable_channel(sdmac->sdma, sdmac->channel); } -- 2.30.2

[PATCH] PM / devfreq: Rework freq_table to be local to devfreq struct

by Christian Marangi

On a devfreq PROBE_DEFER, the freq_table in the driver profile struct, is never reset and may be leaved in an undefined state. This comes from the fact that we store the freq_table in the driver profile struct that is commonly defined as static and not reset on PROBE_DEFER. We currently skip the reinit of the freq_table if we found it's already defined since a driver may declare his own freq_table. This logic is flawed in the case devfreq core generate a freq_table, set it in the profile struct and then PROBE_DEFER, freeing the freq_table. In this case devfreq will found a NOT NULL freq_table that has been freed, skip the freq_table generation and probe the driver based on the wrong table. To fix this and correctly handle PROBE_DEFER, use a local freq_table and max_state in the devfreq struct and never modify the freq_table present in the profile struct if it does provide it.
