Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] initramfs: fix CPIO hardlink check Copy the filenames of hardlinks when inserting them into the hash, since the "name" pointer may point to scratch space (name_buf). Not doing so results in corruption if the scratch space is later overwritten: the wrong file may be hardlinked, or, if the scratch space contains garbage, the link will fail and a 0-byte file will be created instead.

[PATCH] Make initramfs printk a warning on incorrect cpio type It turns out that the "-c" option of cpio is highly unportable even between distros let alone unix variants, and may actually make the wrong type of cpio archive. I just wasted quite some time on this, and the kernel can detect this and warn about it (it's __init memory so it gets thrown away and thus there is no runtime overhead) Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Cc: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

[PATCH] kexec: fix in free initrd when overlapped with crashkernel region It is possible that the reserved crashkernel region can be overlapped with initrd since the bootloader sets the initrd location. When the initrd region is freed, the second kernel memory will not be contiguous. The Kexec_load can cause an oops since there is no contiguous memory to write the second kernel or this memory could be used in the first kernel itself and may not be part of the dump. For example, on powerpc, the initrd is located at 36MB and the crashkernel starts at 32MB. The kexec_load caused panic since writing into non-allocated memory (after 36MB). We could see the similar issue even on other archs. One possibility is to move the initrd outside of crashkernel region. But, the initrd region will be freed anyway before the system is up. This patch fixes this issue and frees only regions that are not part of crashkernel memory in case overlaps. Signed-off-by: Haren Myneni <haren@us.ibm.com> Acked-by: "Eric W.

[PATCH] BLK_DEV_INITRD: do not require BLK_DEV_RAM=y Initramfs initrd images do not need a ramdisk device, so remove this restriction in Kconfig. BLK_DEV_RAM=n saves about 13k on i386. Also without ramdisk device there's no need for "dry run", so initramfs unpacks much faster. People using cramfs, squashfs, or gzipped ext2/minix initrd images are probably smart enough not to turn off ramdisk support by accident.
