* [PATCH] uml: Add static initializations and declarationsJeff Dike2006-01-06
| | | | | | | | | | | Some structure fields were being dynamically initialized when they could be initialized at compile-time instead. This also makes some declarations static (in the C sense).

* [PATCH] swsusp: save image header firstRafael J. Wysocki2006-01-06
| | | | | | | | | | | | | | | | | | | | This makes the swsusp_info structure become the header of the image in the literal sense (ie. it is saved to the swap and read before any other image data with the help of the swsusp's swap map structure, so generally it is treated in the same way as the rest of the image). The main thing it does is to make swsusp_header contain the offset of the swap map used to track the image data pages rather than the offset of swsusp_info.  Simultaneously, swsusp_info becomes the first image page written to the swap. The other changes are generally consequences of the above with a few exceptions (there's some consolidation in the image reading part as a few functions turn into trivial wrappers around something else).

* [PATCH] swsusp: fix enough_free_memRafael J. Wysocki2006-01-06
| | | | | | | | | | | | | | | | | | This patch fixes a problem with the function enough_free_mem() used by swsusp to verify if there is a sufficient number of memory pages available to it to create and save the suspend image. Namely, enough_free_mem() uses nr_free_pages() to obtain the number of free memory pages, which is incorrect, because this function returns the total number of free pages, including free highmem pages, and the highmem pages cannot be used by swsusp for storing the image data. The patch makes enough_free_mem() avoid counting the free highmem pages as available to swsusp. Signed-off-by: Rafael J.

* [PATCH] swsusp: introduce the swap map structureRafael J. Wysocki2006-01-06
| | | | | | | | | | | | | | | | | | | | | This patch introduces the swap map structure that can be used by swsusp for keeping tracks of data pages written to the swap.  The structure itself is described in a comment within the patch. The overall idea is to reduce the amount of metadata written to the swap and to write and read the image pages sequentially, in a file-alike way. This makes the swap-handling part of swsusp fairly independent of its snapshot-handling part and will hopefully allow us to completely separate these two parts in the future. This patch is needed to remove the suspend image size limit imposed by the limited size of the swsusp_info structure, which is essential for x86-64 systems with more than 512 MB of RAM.

* [PATCH] i386: ioapic virtual wire mode fixVivek Goyal2006-01-06
| | | | | | | | | | | | | | | | | | | | | o Currently, during kexec reboot, IOAPIC is re-programmed back to virtual wire mode if there was an i8259 connected to it. This enables getting timer interrupts in second kernel in legacy mode. o After putting into virtual wire mode, IOAPIC delivers the i8259 interrupts to CPU0. This works well for kexec but not for kdump as we might crash on a different CPU and second kernel will not see timer interrupts. o This patch modifies the redirection table entry to deliver the timer interrupts to the cpu we are rebooting (instead of hardcoding to zero). This ensures that second kernel receives timer interrupts even on a non-boot cpu.

* [PATCH] x86: change_page_attr() fixDave Jones2006-01-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'make rodata read-only' patch in -mm exposes a latent bug in the 32-bit change_page_attr() function, which causes certain CPUs (Those with NX basically) to reboot instantly after pages are marked read-only. The same bug got fixed a while back on x86-64, but never got propagated to i386. Stuart Hayes from Dell also picked up on this last June, but it never got fixed, as the only thing affected by it aparently was the nvidia driver. Blatantly stealing description from his post.. "It doesn't appear to be fixed (in the i386 arch). The change_page_attr()/split_large_page() code will still still set all the 4K PTEs to PAGE_KERNEL (setting the _PAGE_NX bit) when a large page needs to be split. This wouldn't be a problem for the bulk of the kernel memory, but there are pages in the lower 4MB of memory that's free, and are part of large executable pages that also contain kernel code. If change_page_attr() is called on these, it will set the _PAGE_NX bit on the whole 2MB region that was covered by the large page, causing a large chunk of kernel code to be non-executable."

* [PATCH] x86: convert bigsmp to use flat physical modeAshok Raj2006-01-06
| | | | | | | | | | | | | | | | | | | | | | | | When we bring up a new CPU via INIT/startup IPI messages, the CPU that's coming up sends a xTPR message to the chipset. Intel chipsets (at least) don't provide any architectural guarantee on what the chipset will do with this message. For example, the E850x chipsets uses this xTPR message to interpret the interrupt operating mode of the platform. When the CPU coming online sends this message, it always indicates that it is in logical flat mode. For the CPU hotplug case, the platform may already be functioning in cluster APIC mode at this time, the chipset can get confused and mishandle I/O device and IPI interrupt routing. The situation eventually gets corrected when the new CPU sends another xTPR update when we switch it to cluster mode, but there's a window during which the chipset may be in an inconsistent state. This patch avoids this problem by using the flat physical interrupt delivery mode instead of cluster mode for bigsmp (>8 cpu) support.
