This usually happens when there are large # number of namespaces created in the region backed by the dimm and the # label-index spans max possible config-area. An error of the form below # usually reported in the kernel logs: # # [ 255.293912] nvdimm: probe of nmem0 failed with error -22 # # The patch fixes these validation checks there by letting libnvdimm # access the entire config-area. # # Fixes: 53e80bd042773('powerpc/nvdimm: Add support for multibyte read/write for metadata') # Signed-off-by: Vaibhav Jain <vaibhav@linux.ibm.com> # Reviewed-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20190927062002.3169-1-vaibhav@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 612ee81b9461475b5a5612c2e8d71559dd3c7920 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_corenet64_smp_defconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- corenet64_smp_defconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next_corenet64_smp_defconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/include/linux/acpi.h:15, from /kisskb/src/include/linux/i2c.h:13, from /kisskb/src/include/uapi/linux/fb.h:6, from /kisskb/src/include/linux/fb.h:6, from /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c:20: /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c: In function 'fsl_diu_ioctl': /kisskb/src/include/linux/device.h:1743:2: warning: this statement may fall through [-Wimplicit-fallthrough=] _dev_warn(dev, dev_fmt(fmt), ##__VA_ARGS__) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c:1287:3: note: in expansion of macro 'dev_warn' dev_warn(info->dev, ^~~~~~~~ /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c:1290:2: note: here case MFB_SET_PIXFMT: ^~~~ In file included from /kisskb/src/include/linux/acpi.h:15, from /kisskb/src/include/linux/i2c.h:13, from /kisskb/src/include/uapi/linux/fb.h:6, from /kisskb/src/include/linux/fb.h:6, from /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c:20: /kisskb/src/include/linux/device.h:1743:2: warning: this statement may fall through [-Wimplicit-fallthrough=] _dev_warn(dev, dev_fmt(fmt), ##__VA_ARGS__) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c:1296:3: note: in expansion of macro 'dev_warn' dev_warn(info->dev, ^~~~~~~~ /kisskb/src/drivers/video/fbdev/fsl-diu-fb.c:1299:2: note: here case MFB_GET_PIXFMT: ^~~~ INFO: Uncompressed kernel (size 0x10d30c0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x1100000) Image Name: Linux-5.4.0-rc2-g612ee81b9461 Created: Fri Oct 11 00:13:38 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 7260066 Bytes = 7089.91 KiB = 6.92 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-next_corenet64_smp_defconfig_powerpc-gcc8 # Build took: 0:03:13.260996
