Broken earlier by me by a x86-64 patch. The code was optimized away, but the compiler still complained about an undeclared function. Signed-off-by:

Patch from Nicolas Pitre Quoting RMK: |pte_write() just says that the page _may_ be writable. It doesn't say |that the MMU is programmed to allow writes. If pte_dirty() doesn't |return true, that means that the page is _not_ writable from userspace. |If you write to it from kernel mode (without using put_user) you'll |bypass the MMU read-only protection and may end up writing to a page |owned by two separate processes.

pfn_to_page() and others need to access both memnode_shift and the very first bytes of memnodemap[]. If we force memnode_shift to be just before the memnodemap array, we can reduce the memory footprint to one cache line instead of two for most setups. This patch introduce a 'memnode' structure where shift and map[] are carefully placed. Signed-off-by:

arch/x86_64/kernel/aperture.c: The search for the AGP bridge has been extended to search for all the 256 buses instead of the first 32. This is required since on a some systems, the bridge may be located on a bus much farther than the first 32. By searching all 256 buses, we guarantee that the search succeeds on such systems. arch/x86_64/kernel/pci-gart.c: The search for the Northbridge is not limited to just bus 0 anymore. This is required because on certain systems, we may not find one on bus 0. Signed-off-by:

o check_timer() routine fails while second kernel is booting after a crash on an opetron box. Problem happens because timer vector (0x31) seems to be locked. o After a system crash, it is not safe to service interrupts any more, hence interrupts are disabled. This leads to pending interrupts at LAPIC. LAPIC sends these interrupts to the CPU during early boot of second kernel. Other pending interrupts are discarded saying unexpected trap but timer interrupt is serviced and CPU does not issue an LAPIC EOI because it think this interrupt came from i8259 and sends ack to 8259. This leads to vector 0x31 locking as LAPIC does not clear respective ISR and keeps on waiting for EOI. o This patch issues extra EOI for the pending interrupts who have ISR set. o Though today only timer seems to be the special case because in early boot it thinks interrupts are coming from i8259 and uses mask_and_ack_8259A() as ack handler and does not issue LAPIC EOI. But probably doing it in generic manner for all vectors makes sense. Signed-off-by:

This patch puts the infrastructure in place to allow for a reordering of functions based inside the vmlinux. The general idea is that it is possible to put all "common" functions into the first 2Mb of the code, so that they are covered by one TLB entry. This as opposed to the current situation where a typical vmlinux covers about 3.5Mb (on x86-64) and thus 2 TLB entries. This is done by enabling the -ffunction-sections flag in gcc, which puts each function in its own ELF section, so that the linker can then order them in a way defined by the linker script. As per previous discussions, Linus said he wanted a "static" list for this, eg a list provided by the kernel tarbal, so that most people have the same ordering at least. A script is provided to create this list based on readprofile(1) output. The included list is provisional, and entirely biased on my own testbox and me running a few kernel compiles and some other things. I think that to get to a better list we need to invite people to submit their own profiles, and somehow add those all up and base the final list on that. I'm willing to do that effort if this is ends up being the prefered approach. Such an effort probably needs to be repeated like once a year or so to adopt to the changing nature of the kernel. Made it a CONFIG with default n because it increases link times dramatically. Signed-off-by:
