Patches have been taken from kexec-tools and makedumpfile to fix issue
with `makedumpfile --mem-usage /proc/kcore`.
One of the patch is from kexec-tools and rest are from makedumpfile.
All the patches have been acked upstream and applies without conflict.
There is one patch
(kexec-tools-2.0.14-x86-x86_64-Fix-format-warning-with-die.patch), which
fixes koji build issue.
All the patches are backport of upstream commits.
Patches has been tested with kernel 4.11.0-0.rc1.git0.1.fc26.x86_64.
# makedumpfile --mem-usage /proc/kcore -f
The kernel version is not supported.
The makedumpfile operation may be incomplete.

+Subject: [PATCH] build_mem_phdrs(): check if p_paddr is invalid
+
+Currently, all the p_paddr of PT_LOAD headers are assigned to 0, which
+is not correct and could be misleading, since 0 is a valid physical
+address.
+
+Upstream kernel commit "464920104bf7 /proc/kcore: update physical
+address for kcore ram and text" fixed it and now invalid PT_LOAD is
+assigned as -1.
+
+kexec/arch/i386/crashdump-x86.c:get_kernel_vaddr_and_size() uses kcore
+interface and so calls build_mem_phdrs() for kcore PT_LOAD headers.
+
+This patch fixes build_mem_phdrs() to check if p_paddr is invalid.

+464920104bf7(/proc/kcore: update physical address for kcore ram and

+
+In set_kcore_vmcoreinfo, we calculate the virtual address of vmcoreinfo
+by OR operation as below:
+
+ kvaddr = (ulong)vmcoreinfo_addr | PAGE_OFFSET;
+
+When mm sections kaslr is not enabled, this is correct since the
+starting address of direct mapping section is 0xffff880000000000 which
+is 1T aligned. Usually system with memory below 1T won't cause problem.
+
+However with mm section kaslr enabled, the starting address of direct
+mapping is 1G aligned. The above code makes kvaddr unsure.
+
+So change it to adding operation:
+ kvaddr = (ulong)vmcoreinfo_addr + PAGE_OFFSET;

+
+PT_LOAD of kcore does not have valid p_paddr values for kernel version

+This patch fixes the makedumpfile so that it does not allow to work

+ for none direct mapped regions
+
+A kcore PT_LOAD can have a section from vmalloc region. However,
+physical address in that header would be invalid (-1) after kernel
+commit 464920104bf7 (/proc/kcore: update physical address for kcore ram
+and text). Therefore, check for valid physical address while calculating
+page_offset or phys_offset.

+Subject: [PATCH] x86/x86_64: Fix format warning with die()
+
+Fedora koji uses gcc version 7.0.1-0.12.fc27, and it generates a build
+warning
+
+ kexec/arch/i386/kexec-elf-x86.c:299:3: error: format not a string
+ literal and no format arguments [-Werror=format-security]
+ die(error_msg);
+ ^~~
+ cc1: some warnings being treated as errors
+
+error_msg can have a format specifier as well in string. In such cases,
+if there is no other arguments for the format variable then code will
+try to access a non existing argument. Therefore, use 1st argument as
+format specifier for string print and pass error_msg as the string to be
+printed.
+
+While doing that,also use const qualifier before "char *error_msg".
