Revert "kdump, vmcoreinfo: report memory sections virtual addresses"
This reverts commit 0549a3c02efb ("kdump, vmcoreinfo: report memory sections virtual addresses"). Commit 0549a3c02efb tells the userspace utility makedumpfile the randomized base address of these memmory sections when mm kaslr is enabled. However the following patch "kexec: export the value of phys_base instead of symbol address" makes makedumpfile not need these addresses any more. Besides we should use VMCOREINFO_NUMBER to export the value of the variable so that we can use the existing number_table mechanism of Makedumpfile to fetch it. So revert it now. If needed we can add it later. http://lists.infradead.org/pipermail/kexec/2016-October/017540.html Link: http://lkml.kernel.org/r/1478568596-30060-1-git-send-email-bhe@redhat.com Signed-off-by: Baoquan He <bhe@redhat.com> Cc: Thomas Garnier <thgarnie@google.com> Cc: Baoquan He <bhe@redhat.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: "H .
