* sata_via: fix support for 5287Tejun Heo2008-10-311-12/+143
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 5287 used to be treated as vt6420 but it didn't work. It's new family of controllers called vt8251 which hosts four SATA ports as M/S of the two ATA ports. This configuration is rather peculiar in that although the M/S devices are on the same port, each have its own SCR (or equivalent link status/control) registers which screws up the port-link-device hierarchy assumed by libata. Another controller which falls into this category is ata_piix w/ SIDPR access. libata now has facility to deal with this class of controllers named slave_link. A low level driver for such controllers can just call ata_slave_link_init() on the respective ports and libata will handle all the difficult parts like following up with single SRST after hardresetting both ports. This patch creates new controller class vt8251, implements slave_link aware init sequence and config space based SCR access for it and moves 5287 to the new class. This patch is based on Joseph Chan's larger patch which was created before slave_link was implemented in libata. http://thread.gmane.org/gmane.linux.kernel.commits.mm/40640 Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Joseph Chan <JosephChan@via.com.tw> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
* libata: Avoid overflow in ata_tf_to_lba48() when tf->hba_lbal > 127Roland Dreier2008-10-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | In ata_tf_to_lba48(), when evaluating (tf->hob_lbal & 0xff) << 24 the expression is promoted to signed int (since int can hold all values of u8). However, if hob_lbal is 128 or more, then it is treated as a negative signed value and sign-extended when promoted to u64 to | into sectors, which leads to the MSB 32 bits of section getting set incorrectly. For example, Phillip O'Donnell <phillip.odonnell@gmail.com> reported that a 1.5GB drive caused: ata3.00: HPA detected: current 2930277168, native 18446744072344861488 where 2930277168 == 0xAEA87B30 and 18446744072344861488 == 0xffffffffaea87b30 which shows the problem when hob_lbal is 0xae. Fix this by adding a cast to u64, just as is used by for hob_lbah and hob_lbam in the function.

| * Fix incompatibility with versions of Perl less than 5.6.0Jeremy Huntwork2008-10-292-13/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix headers_install.pl and headers_check.pl to be compatible with versions of Perl less than 5.6.0. It has been tested with Perl 5.005_03 and 5.8.8. I realize this may not be an issue for most people, but there will still be some that hit it, I imagine. There are three basic issues: 1. Prior to 5.6.0 open() only used 2 arguments, and the versions of the scripts in 2.6.27.1 use 3. 2. 5.6.0 also introduced the ability to use uninitialized scalar variables as file handles, which the current scripts make use of. 3. Lastly, 5.6.0 also introduced the pragma 'use warnings'. We can use the -w switch and be backwards compatible.

| | | | | | | | | | | | | | | | | | | | | | | | Architectures which have moved their includes to arch/<ARCH>/include now list the headers twice in the source listing used by "make cscope" and friends, causing those tools to list symbols twice. Skipping these files in the ALLSOURCE_ARCHS pass rather than removing the ALLINCLUDE_ARCHS pass preserves the semantics of the later.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | setlocalversion used to use an abbreviated git commit sha1 to generate the tag. This was changed in commit d882421f4e08ddf0a94245cdbe516db260aa6f41 "kbuild: change CONFIG_LOCALVERSION_AUTO to use a git-describe-ish format" to use git describe to come up with a tag. Which is nice, but git describe sometimes can't describe the revision. Commit 56b2f0706d82535fd8d85503f2dcc0be40c8e55d ("setlocalversion: do not describe if there is nothing to describe") addressed this, but there is still no tag generated. So, generate a plain abbreviated sha1 tag like setlocalversion used to when git describe comes up short.

Fix this by removing the Fam11h northbridge id from the scan list of K8 northbridges.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: fix kdump crash on 32-bit sparsemem kernels Since linux-2.6.27, kdump has failed on i386 sparsemem kernel. 1st-kernel gets a panic just before switching to 2nd-kernel. The cause is that a kernel accesses invalid mem_section by page_to_pfn(image->swap_page) at machine_kexec(). image->swap_page is allocated if kexec for hibernation, but it is not allocated if kdump. So if kdump, a kernel should not access the mem_section corresponding to image->swap_page. The attached patch fixes this invalid access.
