+Subject: sadump: Fix failure of reading __per_cpu_load memory
+References: bsc#1168798
+Upstream: merged
+Git-commit: c9e078531efaffbe6f780221d40bdac21a84855b
+
+Creating vmcore from sadump by makedumpfile fails with the following
+error messages since kernel-4.19 with PTI (Page Table Isolation)
+enabled:
+
+  __vtop4_x86_64: Can't get a valid pte.
+  readmem: Can't convert a virtual address(ffffffffb2986000) to physical address.
+  readmem: type_addr: 0, addr:ffffffffb2986000, size:8
+  per_cpu_init: Can't read __per_cpu_load memory.
+
+This is caused by the following patch:
+https://github.com/torvalds/linux/commit/c40a56a7818cfe735fc93a69e1875f8bba834483
+
+The above patch clears _PAGE_PRESENT bit of __per_cpu_load memory, so
+__vtop4_x86_64 fails to convert the virtual address of the
+__per_cpu_load.
+
+To fix this issue, this patch changes sanity check of per_cpu_ptr()
+to use address of the __per_cpu_load instead of data of the memory.
