From: Mahesh Salgaonkar<mah...@linux.vnet.ibm.com>Introduce a PT_NOTE program header that points to physical address of vmcoreinfo_note buffer declared in kernel/kexec.c. The vmcoreinfo note buffer is populated during crash_fadump() at the time of system crash.

Although they are static functions, it is still better to name them with "fadump_" prefix... Thanks. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
