2005-08-04	[PATCH] x86-64: use proper VM_FAULT_xxx macros	Alexander Nyberg	1	-3/+3
	x86_64 had hardcoded the VM_ numbers so it broke down when the numbers were changed. Signed-off-by: Alexander Nyberg <alexn@telia.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-06-23	[PATCH] xen: x86_64: use more usermode macro	Vincent Hanquez	1	-2/+2
	Make use of the user_mode macro where it's possible. This is useful for Xen because it will need only to redefine only the macro to a hypervisor call.

2005-06-21	[PATCH] x86_64: TASK_SIZE fixes for compatibility mode processes	Suresh Siddha	1	-1/+1
	Appended patch will setup compatibility mode TASK_SIZE properly. This will fix atleast three known bugs that can be encountered while running compatibility mode apps. a) A malicious 32bit app can have an elf section at 0xffffe000. During exec of this app, we will have a memory leak as insert_vm_struct() is not checking for return value in syscall32_setup_pages() and thus not freeing the vma allocated for the vsyscall page. And instead of exec failing (as it has addresses > TASK_SIZE), we were allowing it to succeed previously. b) With a 32bit app, hugetlb_get_unmapped_area/arch_get_unmapped_area may return addresses beyond 32bits, ultimately causing corruption because of wrap-around and resulting in SEGFAULT, instead of returning ENOMEM. c) 32bit app doing this below mmap will now fail. mmap((void *)(0xFFFFE000UL), 0x10000UL, PROT_READ\|PROT_WRITE, MAP_FIXED\|MAP_PRIVATE\|MAP_ANON, 0, 0); Signed-off-by: Zou Nan hai <nanhai.zou@intel.com> Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Cc: Andi Kleen <ak@muc.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-05-17	[PATCH] x86_64: When checking vmalloc mappings don't use pte_page	Andi Kleen	1	-2/+9
	The PTEs can point to ioremap mappings too, and these are often outside mem_map. The NUMA hash page lookup functions cannot handle out of bounds accesses properly. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-16	[PATCH] x86_64: Use a common function to find code segment bases	Andi Kleen	1	-7/+5
	To avoid some code duplication. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-16	[PATCH] x86_64: Use a VMA for the 32bit vsyscall	Andi Kleen	1	-12/+0
	Use a real VMA to map the 32bit vsyscall page This interacts better with Hugh's upcomming VMA walk optimization Also removes some ugly special cases. Code roughly modelled after the ppc64 vdso version from Ben Herrenschmidt.

2005-04-16	Linux-2.6.12-rc2v2.6.12-rc2	Linus Torvalds	1	-0/+579
	Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
