2007-07-29Introduce CONFIG_SUSPEND for suspend-to-Ram and standbyRafael J. Wysocki7-53/+69
Introduce CONFIG_SUSPEND representing the ability to enter system sleep states, such as the ACPI S3 state, and allow the user to choose SUSPEND and HIBERNATION independently of each other. Make HOTPLUG_CPU be selected automatically if SUSPEND or HIBERNATION has been chosen and the kernel is intended for SMP systems. Also, introduce CONFIG_PM_SLEEP which is automatically selected if CONFIG_SUSPEND or CONFIG_HIBERNATION is set and use it to select the code needed for both suspend and hibernation. The top-level power management headers and the ACPI code related to suspend and hibernation are modified to use the new definitions (the changes in drivers/acpi/sleep/main.c are, mostly, moving code to reduce the number of ifdefs). There are many other files in which CONFIG_PM can be replaced with CONFIG_PM_SLEEP or even with CONFIG_SUSPEND, but they can be updated in the future. Signed-off-by: Rafael J.

2007-07-28Provide timespec to guests rather than jiffies clock.Rusty Russell4-24/+57
A non-periodic clock_event_device and the "jiffies" clock don't mix well: tick_handle_periodic() can go into an infinite loop. Currently lguest guests use the jiffies clock when the TSC is unusable. Instead, make the Host write the current time into the lguest page on every interrupt. This doesn't cost much but is more precise and at least as accurate as the jiffies clock. It also gets rid of the GET_WALLCLOCK hypercall. Also, delay setting sched_clock until our clock is set up, otherwise the early printk timestamps can go backwards (not harmful, just ugly).

2007-07-28Fix lguest bzImage loading with CONFIG_RELOCATABLE=yRusty Russell1-0/+5
Jason Yeh sent his crashing .config: bzImages made with CONFIG_RELOCATABLE=y put the relocs where the BSS is expected, and we crash with unusual results such as: lguest: unhandled trap 14 at 0xc0122ae1 (0xa9) Relying on BSS being zero was merely laziness on my part, and unfortunately, lguest doesn't go through the normal startup path (which does this in asm).

2007-07-27Fix "use after free" / "double free" bug in ati_create_gatt_pages / ↵Jesper Juhl1-7/+2
ati_free_gatt_pages Hi, Coverity spotted a "use after free" bug in drivers/char/agp/ati-agp.c::ati_create_gatt_pages(). The same one that was in drivers/char/agp/amd-k7-agp.c::amd_create_gatt_pages() The problem is this: If "entry = kzalloc(sizeof(struct ati_page_map), GFP_KERNEL);" fails, then there's a loop in the function to free all entries allocated so far and break out of the allocation loop. That in itself is pretty sane, but then the (now freed) 'tables' is assigned to ati_generic_private.gatt_pages and 'retval' is set to -ENOMEM which causes ati_free_gatt_pages(); to be called at the end of the function. The problem with this is that ati_free_gatt_pages() will then loop 'ati_generic_private.num_tables' times and try to free each entry in tables[] - this is bad since tables has already been freed and furthermore it will call kfree(tables) at the end - a double free. This patch removes the freeing loop in ati_create_gatt_pages() and instead relies entirely on the call to ati_free_gatt_pages() to free everything we allocated in case of an error. It also sets ati_generic_private.num_tables to the actual number of entries allocated instead of just using the value passed in from the caller - this ensures that ati_free_gatt_pages() will only attempt to free stuff that was actually allocated. Note: I'm in no way intimate with this code and I have no way to actually test this patch (besides compile test it), so while I've tried to be careful in reading the code and make sure the patch does the right thing an ACK from someone who actually knows the code in-depth would be very much appreciated.

This patch fixes sysfs exit code for the EDAC PCI device in a similiar manner and the previous fixes for EDAC_MC and EDAC_DEVICE. It removes the old (and incorrect) completion model and uses reference counts on per instance kobjects and on the edac core module. This pattern was applied to the edac_mc and edac_device code, but the EDAC PCI code was missed. In addition, this fixes a system hang after a low level driver was unloaded.
