2007-07-11	sysfs: kill unnecessary attribute->owner	Tejun Heo	1	-3/+3
	sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded. For more info regarding lifetime rule cleanup, please read the following message. http://article.gmane.org/gmane.linux.kernel/510293 (tweaked by Greg to not delete the field just yet, to make it easier to merge things properly.)

2007-05-02	remove "struct subsystem" as it is no longer needed	Greg Kroah-Hartman	1	-6/+6
	We need to work on cleaning up the relationship between kobjects, ksets and ktypes. The removal of 'struct subsystem' is the first step of this, especially as it is not really needed at all. Thanks to Kay for fixing the bugs in this patch. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-01-26	[PATCH] Fix race in efi variable delete code	Matt Domsch	1	-17/+12
	Fix race when deleting an EFI variable and issuing another EFI command on the same variable. The removal of the variable from the efivars_list should be done in efivar_delete and not delayed until the kobject release. Furthermore, remove the item from the list at module unload time, and use list_for_each_entry_safe() rather than list_for_each_safe() for readability. Tested on ia64.

2006-03-26	[PATCH] EFI: keep physical table addresses in efi structure	Bjorn Helgaas	1	-14/+14
	Almost all users of the table addresses from the EFI system table want physical addresses. So rather than doing the pa->va->pa conversion, just keep physical addresses in struct efi. This fixes a DMI bug: the efi structure contained the physical SMBIOS address on x86 but the virtual address on ia64, so dmi_scan_machine() used ioremap() on a virtual address on ia64. This is essentially the same as an earlier patch by Matt Tolentino: http://marc.theaimsgroup.com/?l=linux-kernel&m=112130292316281&w=2 except that this changes all table addresses, not just ACPI addresses. Matt's original patch was backed out because it caused MCAs on HP sx1000 systems. That problem is resolved by the ioremap() attribute checking added for ia64.

2005-04-16	Linux-2.6.12-rc2	Linus Torvalds	1	-0/+781
	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!
