-Subject: [PATCH 1/9] kexec: exntend the semantics of kexec_iomem_for_each_line
-
-The current kexec_iomem_for_each_line() counts up all the lines for which
-a callback function returns zero(0) or positive, and otherwise it stops
-further scanning.
-This behavior is incovenient in some cases. For instance, on arm64, we want
-to count up "System RAM" entries, but need to skip "reserved" entries.
-
-So this patch extends the semantics so that we will continue to scan
-succeeding entries but not count lines for which a callback function
-returns positive.
-
-The current users of kexec_iomem_for_each_line(), arm, sh and x86, will not
-be affected by this change because
-* arm
-  The callback function only returns -1 or 0, and the return value of
-  kexec_iomem_for_each_line() will never be used.
-* sh, x86
-  The callback function may return (-1 for sh,) 0 or 1, but always returns
-  1 once we have reached the maximum number of entries allowed.
-  Even so the current kexec_iomem_for_each_line() counts them up.
-  This change actually fixes this bug.

-e.g. musl since this type is not defined by POSIX. Define _GNU_SOURCE to

-Subject: [PATCH 1/2] 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".

-Subject: [PATCH 2/9] kexec: generalize and rename get_kernel_stext_sym()
-
-get_kernel_stext_sym() has been defined for both arm and i386. Other
-architecture might need some other kernel symbol address. Therefore rewrite
-this function as generic function to get any kernel symbol address.
-
-More over, kallsyms is not arch specific representation, therefore have
-common function for all arches.

-Subject: [PATCH 3/9] arm64: identify PHYS_OFFSET correctly
-
-Due to the kernel patch, commit e7cd190385d1 ("arm64: mark reserved
-memblock regions explicitly in iomem"), the current code will not be able
-to identify the correct value of PHYS_OFFSET if some "reserved" memory
-region, which is likely to be UEFI runtime services code/data, exists at
-an address below the first "System RAM" regions.
-
-This patch fixes this issue.

-We go through /proc/iomem to find out a) and b) which are marked
