Hi Ross
Well，through my test，this patch works well on poky-lsb without compile error.

Does this work on poky-lsb? Previous upgrades were failing with that due to the security flags being enabled.

-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.

-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".

-
-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

-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.

-Subject: [PATCH 6/9] arm64: kdump: set up kernel image segment
-
-On arm64, we can use the same kernel image as 1st kernel, but
-we have to modify the entry point as well as segments' addresses
-in the kernel's elf header in order to load them into correct places.
