linux.git/fs/proc/vmcore.c, branch v2.6.16 Linux kernel source tree [PATCH] kdump: vmcore compilation warning fix 2006-01-12T02:42:11+00:00 Vivek Goyal vgoyal@in.ibm.com 2006-01-11T20:17:37+00:00 9e9e3941d0a3497c1e7fb9ce62059705825bb775 o fs/proc/vmcore.c compilation gives warnings on ppc64. The reason being that u64 is defined as unsigned long hence u64* is not same as loff_t* and compiler cribs. o Changed the parameter type to u64* instead of loff_t* to resolve the conflict.

[PATCH] kdump: read previous kernel's memory 2006-01-10T16:01:28+00:00 Vivek Goyal vgoyal@in.ibm.com 2006-01-10T04:51:50+00:00 4ae362be509306eafa6441603686d33fefe321c1 - Moving the crash_dump.c file to arch dependent part as kmap_atomic_pfn is specific to i386 and highmem may not exist in other archs. - Use ioremap for x86_64 to map the previous kernel memory. - In copy_oldmem_page(), we now directly copy to the user/kernel buffer and avoid the unneccesary copy to a kmalloc'd page.

[PATCH] kdump: Parse elf32 headers and export through /proc/vmcore 2005-06-25T23:24:53+00:00 Vivek Goyal vgoyal@in.ibm.com 2005-06-25T21:58:22+00:00 72658e9d5004fc0dd807bea9eda49e6a52e40103 o Adds support for parsing core ELF32 headers. o I am expecting ELF32 support to go away down the line. This patch has been introduced for testing purposes as gdb can not parse ELF64 headers for i386. When a decent user space solution is available, ELF32 support can go away.
