This gets rid of\nan include of pgtable.h from processor.h, which can cause include loops.\n\nOn i386, task_size is calculated early in boot by probing the address space in\na binary search to figure out where the boundary between usable and non-usable\nmemory is. This tries to make sure that a page that is considered to be in\nuserspace is, or can be made, read-write. I\u0027m concerned about a system-global\nVDSO page in kernel memory being hit and considered to be a userspace page.\n\nOn x86_64, task_size is just the old value of CONFIG_TOP_ADDR.\n\nA bunch of config variable are gone now. CONFIG_TOP_ADDR is directly replaced\nby TASK_SIZE. NEST_LEVEL is gone since the relocation of the stubs makes it\nirrelevant. All the HOST_VMSPLIT stuff is gone. All references to these in\narch/um/Makefile are also gone.\n\nI noticed and fixed a missing extern in os.h when adding os_get_task_size.\n\nNote: This has been revised to fix the 32-bit UML on 64-bit host bug that\nMiklos ran into.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nCc: Miklos Szeredi \u003cmiklos@szeredi.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "42a2b54ce8c7b9d4f418995a7950e7e2e15e52ce", "tree": "30bcb0ea0a4ee6d5091b1b9a85589cff8b1863fc", "parents": [ "b7c000cbc4f1fa7b82efa95b34f00c2adbeaa3fe" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Mon Feb 04 22:31:00 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Feb 05 09:44:29 2008 -0800" }, "message": "uml: clean up TASK_SIZE usage\n\nClean up the calculation and use of the usable address space size on the host.\n\ntask_size is gone, replaced with TASK_SIZE, which is calculated from\nCONFIG_TOP_ADDR. get_kmem_end and set_task_sizes_skas are also gone.\n\nhost_task_size, which refers to the entire address space usable by the UML\nkernel and which may be larger than the address space usable by a UML process,\nsince that has to end on a pgdir boundary, is replaced by CONFIG_TOP_ADDR.\n\nSTACK_TOP is now TASK_SIZE minus the two stub pages.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "8192ab42bf60e1e9b7efa046990e9cc5e4a95cf4", "tree": "f61fee85b0eccbc055ec8c5a98932b20eca64bf1", "parents": [ "9157f90f08f7db3188cd06971f41cb2ba5646e57" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Mon Feb 04 22:30:53 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Feb 05 09:44:28 2008 -0800" }, "message": "uml: header untangling\n\nUntangle UML headers somewhat and add some includes where they were\nneeded explicitly, but gotten accidentally via some other header.\n\narch/um/include/um_uaccess.h loses asm/fixmap.h because it uses no\nfixmap stuff and gains elf.h, because it needs FIXADDR_USER_*, and\narchsetjmp.h, because it needs jmp_buf.\n\npmd_alloc_one is uninlined because it needs mm_struct, and that\u0027s\ninconvenient to provide in asm-um/pgtable-3level.h.\n\nelf_core_copy_fpregs is also uninlined from elf-i386.h and\nelf-x86_64.h, which duplicated the code anyway, to\narch/um/kernel/process.c, so that the reference to current_thread\ndoesn\u0027t pull sched.h or anything related into asm/elf.h.\n\narch/um/sys-i386/ldt.c, arch/um/kernel/tlb.c and\narch/um/kernel/skas/uaccess.c got sched.h because they dereference\ntask_structs.
