2008-04-26x86_64 ia32 ptrace: convert to compat_arch_ptraceRoland McGrath

2008-04-26x86: remove NexGen supportDmitri Vorobiev
It is claimed that NexGen CPUs were never shipped: http://lkml.org/lkml/2008/4/20/179 Also, the kernel support for these chips has been broken for a long time, the code intended to support NexGen thereby being essentially dead. As an outcome of the discussion that can be found using the URL above, this patch removes the NexGen support altogether. The changes in this patch survived a defconfig build for i386, a couple of successful randconfig builds, as well as a runtime test, which consisted in booting a 32-bit x86 box up to the shell prompt.

2008-04-24xen: replace callers of alloc_vm_area()/free_vm_area() with xen_ prefixed oneIsaku Yamahata
Don't use alloc_vm_area()/free_vm_area() directly, instead define xen_alloc_vm_area()/xen_free_vm_area() and use them. alloc_vm_area()/free_vm_area() are used to allocate/free area which are for grant table mapping. Xen/x86 grant table is based on virtual address so that alloc_vm_area()/free_vm_area() are suitable. On the other hand Xen/ia64 (and Xen/powerpc) grant table is based on pseudo physical address (guest physical address) so that allocation should be done differently. The original version of xenified Linux/IA64 have its own allocate_vm_area()/free_vm_area() definitions which don't allocate vm area contradictory to those names. Now vanilla Linux already has its definitions so that it's impossible to have IA64 definitions of allocate_vm_area()/free_vm_area(). Instead introduce xen_allocate_vm_area()/xen_free_vm_area() and use them.

2008-04-24x86: unify KERNEL_PGD_PTRSJeremy Fitzhardinge
Make KERNEL_PGD_PTRS common, as previously it was only being defined for 32-bit. There are a couple of follow-on changes from this: - KERNEL_PGD_PTRS was being defined in terms of USER_PGD_PTRS. The definition of USER_PGD_PTRS doesn't really make much sense on x86-64, since it can have two different user address-space configurations. I renamed USER_PGD_PTRS to KERNEL_PGD_BOUNDARY, which is meaningful for all of 32/32, 32/64 and 64/64 process configurations. - USER_PTRS_PER_PGD was also defined and was being used for similar purposes. Converting its users to KERNEL_PGD_BOUNDARY left it completely unused, and so I removed it.

2008-04-24x86: introduce /dev/mem restrictions with a config optionArjan van de Ven
This patch introduces a restriction on /dev/mem: Only non-memory can be read or written unless the newly introduced config option is set. The X server needs access to /dev/mem for the PCI space, but it doesn't need access to memory; both the file permissions and SELinux permissions of /dev/mem just make X effectively super-super powerful. With the exception of the BIOS area, there's just no valid app that uses /dev/mem on actual memory. Other popular users of /dev/mem are rootkits and the like. (note: mmap access of memory via /dev/mem was already not allowed since a really long time) People who want to use /dev/mem for kernel debugging can enable the config option. The restrictions of this patch have been in the Fedora and RHEL kernels for at least 4 years without any problems.

2008-04-19asm-generic: add node_to_cpumask_ptr macroMike Travis
Create a simple macro to always return a pointer to the node_to_cpumask(node) value. This relies on compiler optimization to remove the extra indirection: #define node_to_cpumask_ptr(v, node) \ cpumask_t _##v = node_to_cpumask(node), *v = &_##v For those systems with a large cpumask size, then a true pointer to the array element can be used: #define node_to_cpumask_ptr(v, node) \ cpumask_t *v = &(node_to_cpumask_map[node]) A node_to_cpumask_ptr_next() macro is provided to access another node_to_cpumask value. The other change is to always include asm-generic/topology.h moving the ifdef CONFIG_NUMA to this same file. Note: there are no references to either of these new macros in this patch, only the definition.
