* [PATCH] i386: use set_pte macros in a couple places where they were missingZachary Amsden2005-09-053-4/+5
| | | | | | | | | | | | | | | | | | | | Also, setting PDPEs in PAE mode does not require atomic operations, since the PDPEs are cached by the processor, and only reloaded on an explicit or implicit reload of CR3. Since the four PDPEs must always be present in an active root, and the kernel PDPE is never updated, we are safe even from SMIs and interrupts / NMIs using task gates (which reload CR3). Actually, much of this is moot, since the user PDPEs are never updated either, and the only usage of task gates is by the doublefault handler. It appears the only place PGDs get updated in PAE mode is in init_low_mappings() / zap_low_mapping() for initial page table creation and recovery from ACPI sleep state, and these sites are safe by inspection. Getting rid of the cmpxchg8b saves code space and 720 cycles in pgd_alloc on P4.

* [PATCH] i386: load_tls() fixZachary Amsden2005-09-051-7/+12
| | | | | | | | | | | | Subtle fix: load_TLS has been moved after saving %fs and %gs segments to avoid creating non-reversible segments. This could conceivably cause a bug if the kernel ever needed to save and restore fs/gs from the NMI handler. It currently does not, but this is the safest approach to avoiding fs/gs corruption. SMIs are safe, since SMI saves the descriptor hidden state.

| | | | | | | | | | | | | | | | | register management i386 inline assembler cleanup. This change encapsulates descriptor and task register management. Also, it is possible to improve assembler generation in two cases; savesegment may store the value in a register instead of a memory location, which allows GCC to optimize stack variables into registers, and MOV MEM, SEG is always a 16-bit write to memory, making the casting in math-emu unnecessary.

* [PATCH] i386: cleanup serialize msrZachary Amsden2005-09-053-2/+15
| | | | | | | | | | | | | i386 arch cleanup. Introduce the serialize macro to serialize processor state. Why the microcode update needs it I am not quite sure, since wrmsr() is already a serializing instruction, but it is a microcode update, so I will keep the semantic the same, since this could be a timing workaround. As far as I can tell, this has always been there since the original microcode update source.

* [PATCH] i386: inline asm cleanupZachary Amsden2005-09-0515-83/+84
| | | | | | | | | | | | | | | | | | | | | i386 Inline asm cleanup. Use cr/dr accessor functions. Also, a potential bugfix. Also, some CR accessors really should be volatile. Reads from CR0 (numeric state may change in an exception handler), writes to CR4 (flipping CR4.TSD) and reads from CR2 (page fault) prevent instruction re-ordering. I did not add memory clobber to CR3 / CR4 / CR0 updates, as it was not there to begin with, and in no case should kernel memory be clobbered, except when doing a TLB flush, which already has memory clobber. I noticed that page invalidation does not have a memory clobber. I can't find a bug as a result, but there is definitely a potential for a bug here: #define __flush_tlb_single(addr) \ __asm__ __volatile__("invlpg %0": :"m" (*(char *) addr)) Signed-off-by: Zachary Amsden <zach@vmware.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] kdump: Save parameter segment in protected mode (x86)Vivek Goyal2005-09-051-22/+26
| | | | | | | | | | | | | | | | | | | | | | | | | o With introduction of kexec as boot-loader, the assumption that parameter segment will always be loaded at lower address than kernel and will be addressable by early bootup page tables is no longer valid. In kexec on panic case parameter segment might well be loaded beyond kernel image and might not be addressable by early boot page tables. o This case might hit in the scenario where user has reserved a chunk of memory for second kernel, for example 16MB to 64MB, and has also built second kernel for physical memory location 16MB. In this case kexec has no choice but to load the parameter segment at a higher address than new kernel image at safe location where new kernel does not stomp it. o Though problem should automatically go away once relocatable kernel for i386 is in place and kexec can determine the location of new kernel at run time and load parameter segment at lower address than kernel image. But till then this patch can go in (assuming it does not break something else). o This patch moves up the boot parameter saving code. Now boot parameters are copied out in protected mode before page tables are initialized. This will ensure that parameter segment is always addressable irrespective of its physical location.

* [PATCH] vm86: Honor TF bit when emulating an instructionPetr Tesarik2005-09-051-1/+5
| | | | | | | | | | | | | | | If the virtual 86 machine reaches an instruction which raises a General Protection Fault (such as CLI or STI), the instruction is emulated (in handle_vm86_fault). However, the emulation ignored the TF bit, so the hardware debug interrupt was not invoked after such an emulated instruction (and the DOS debugger missed it). This patch fixes the problem by emulating the hardware debug interrupt as the last action before control is returned to the VM86 program.

* [PATCH] x86: fix EFI memory map parsingMatt Tolentino2005-09-055-69/+67
| | | | | | | | | | | | | | | | The memory descriptors that comprise the EFI memory map are not fixed in stone such that the size could change in the future. This uses the memory descriptor size obtained from EFI to iterate over the memory map entries during boot. This enables the removal of an x86 specific pad (and ifdef) in the EFI header. I also couldn't stomach the broken up nature of the function to put EFI runtime calls into virtual mode any longer so I fixed that up a bit as well. For reference, this patch only impacts x86.

* [PATCH] x86: compress the stack layout of do_page_fault()Ingo Molnar2005-09-051-14/+17
| | | | | | | | | | | | | | | | | | | | | This patch pushes the creation of a rare signal frame (SIGBUS or SIGSEGV) into a separate function, thus saving stackspace in the main do_page_fault() stackframe. The effect is 132 bytes less of stack used by the typical do_page_fault() invocation - resulting in a denser cache-layout. (Another minor effect is that in case of kernel crashes that come from a pagefault, we add less space to the already existing frame, giving the crash functions a slightly higher chance to do their stuff without overflowing the stack.)

* [PATCH] ppc64: Add VMX save flag to VPAOlof Johansson2005-09-053-1/+6
| | | | | | | | | | | | | | | | We need to indicate to the hypervisor that it needs to save our VMX registers when switching partitions on a shared-processor system, just as it needs to for FP and PMC registers. This could be made to be on-demand when VMX is used, but we don't do that for FP nor PMC right now either so let's not overcomplicate things.
