* [MIPS] lockdep: fix TRACE_IRQFLAGS_SUPPORTAtsushi Nemoto2006-10-01
| | | | | | | | | | In handle_sys and its variants, we must reload some registers which might be clobbered by trace_hardirqs_on(). Also we must make sure trace_hardirqs_on() called in kernel level (not exception level). Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Please ignore previous message. This patch is adding support for CPU connected to CLE266 chipset. For older CPU this is only way. For "Powersaver" processor this way will be used if ACPI C3 isn't supported. I have tested it. It seems to work exacly like ACPI. But it is less safe. On CLE266 chipset port 0x22 is blocking processor access to PCI bus too. Signed-off-by: Rafa³ Bilski <rafalbilski@interia.pl> Signed-off-by: Dave Jones <davej@redhat.com>

* | [PATCH] paravirt: update pte hookZachary Amsden2006-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a pte_update_hook which notifies about pte changes that have been made without using the set_pte / clear_pte interfaces. This allows shadow mode hypervisors which do not trap on page table access to maintain synchronized shadows. It also turns out, there was one pte update in PAE mode that wasn't using any accessor interface at all for setting NX protection. Considering it is PAE specific, and the accessor is i386 specific, I didn't want to add a generic encapsulation of this behavior yet.

* | [PATCH] paravirt: kpte flushZachary Amsden2006-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Create a new PTE function which combines clearing a kernel PTE with the subsequent flush. This allows the two to be easily combined into a single hypercall or paravirt-op. More subtly, reverse the order of the flush for kmap_atomic. Instead of flushing on establishing a mapping, flush on clearing a mapping. This eliminates the possibility of leaving stale kmap entries which may still have valid TLB mappings. This is required for direct mode hypervisors, which need to reprotect all mappings of a given page when changing the page type from a normal page to a protected page (such as a page table or descriptor table page). But it also provides some nicer semantics for real hardware, by providing extra debug-proofing against using stale mappings, as well as ensuring that no stale mappings exist when changing the cacheability attributes of a page, which could lead to cache conflicts when two different types of mappings exist for the same page.

* | [PATCH] stack overflow safe kdump: safe_smp_processor_id()Fernando Vazquez2006-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a the first of a series of patch-sets aiming at making kdump more robust against stack overflows. This patch set does the following: * Add safe_smp_processor_id function to i386 architecture (this function was inspired by the x86_64 function of the same name). * Substitute "smp_processor_id" with the stack overflow-safe "safe_smp_processor_id" in the reboot path to the second kernel. This patch: On the event of a stack overflow critical data that usually resides at the bottom of the stack is likely to be stomped and, consequently, its use should be avoided. In particular, in the i386 and IA64 architectures the macro smp_processor_id ultimately makes use of the "cpu" member of struct thread_info which resides at the bottom of the stack. x86_64, on the other hand, is not affected by this problem because it benefits from the use of the PDA infrastructure. To circumvent this problem I suggest implementing "safe_smp_processor_id()" (it already exists in x86_64) for i386 and IA64 and use it as a replacement for smp_processor_id in the reboot path to the dump capture kernel. This is a possible implementation for i386. Signed-off-by: Fernando Vazquez <fernando@intellilink.co.jp> Looks-reasonable-to: Andi Kleen <ak@muc.de> Acked-by: "Eric W.

* | [PATCH] kill wall_jiffiesAtsushi Nemoto2006-10-01

So we can kill wall_jiffies completely. This is just a cleanup and logically should not change any real behavior except for one thing: RTC updating code in (old) ppc and xtensa use a condition "jiffies - wall_jiffies == 1". This condition is never met so I suppose it is just a bug. I just remove that condition only instead of kill the whole "if" block.

| * | [PATCH] Re-positioning the bss segmentVivek Goyal2006-09-29

So let's trying reenabling it again.] o Currently bss segment is being placed somewhere in the middle (after .data) section and after bss lots of init section and data sections are coming. Is it intentional? o One side affect of placing bss in the middle is that objcopy keeps the bss in raw binary image (vmlinux.bin) hence unnecessarily increasing the size of raw binary image. (In my case ~600K). It also increases the size of generated bzImage, though the increase is very small (896 bytes), probably a very high compression ratio for stream of zeros. o This patch moves the bss at the end hence reducing the size of bzImage by 896 bytes and size of vmlinux.bin by 600K. o This change benefits in the context of relocatable kernel patches. If kernel bss is not part of compressed data (vmlinux.bin) then it does not have to be decompressed and this area can be used by the decompressor for its execution hence keeping the memory requirements bounded and decompressor code does not stomp over any other data loaded beyond kernel image (As might be the case with bootloaders like kexec).
