2008-04-27KVM: paravirtualized clocksource: host partGlauber de Oliveira Costa
This is the host part of kvm clocksource implementation. As it does not include clockevents, it is a fairly simple implementation. We only have to register a per-vcpu area, and start writing to it periodically. The area is binary compatible with xen, as we use the same shadow_info structure.

2008-04-27KVM: export information about NPT to generic x86 codeJoerg Roedel
The generic x86 code has to know if the specific implementation uses Nested Paging. In the generic code Nested Paging is called Two Dimensional Paging (TDP) to avoid confusion with (future) TDP implementations of other vendors. This patch exports the availability of TDP to the generic x86 code. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Avi Kivity <avi@qumranet.com>

2008-04-26x86_64: fix setup_node_bootmem to support big mem excluding with memmapYinghai Lu
typical case: four sockets system, every node has 4g ram, and we are using: memmap=10g$4g to mask out memory on node1 and node2 when numa is enabled, early_node_mem is used to get node_data and node_bootmap. if it can not get memory from the same node with find_e820_area(), it will use alloc_bootmem to get buff from previous nodes. so check it and print out some info about it. need to move early_res_to_bootmem into every setup_node_bootmem. and it takes range that node has. otherwise alloc_bootmem could return addr that reserved early. depends on "mm: make reserve_bootmem can crossed the nodes".

2008-04-26x86: finalize bitops unificationAlexander van Heukelum
include/asm-x86/bitops_32.h and include/asm-x86/bitops_64.h are now almost identical. The 64-bit version sets ARCH_HAS_FAST_MULTIPLIER and has an extra inline function set_bit_string. The define currently has no influence on the generated code, but it can be argued that setting it on i386 is the right thing to do anyhow. The addition of the extra inline function on i386 does not hurt either. Signed-off-by: Alexander van Heukelum <heukelum@fastmail.fm> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-04-26x86: generic versions of find_first_(zero_)bit, convert i386Alexander van Heukelum
Generic versions of __find_first_bit and __find_first_zero_bit are introduced as simplified versions of __find_next_bit and __find_next_zero_bit. Their compilation and use are guarded by a new config variable GENERIC_FIND_FIRST_BIT. The generic versions of find_first_bit and find_first_zero_bit are implemented in terms of the newly introduced __find_first_bit and __find_first_zero_bit. This patch does not remove the i386-specific implementation, but it does switch i386 to use the generic functions by setting GENERIC_FIND_FIRST_BIT=y for X86_32.

2008-04-26x86: merge the simple bitops and move them to bitops.hAlexander van Heukelum
Some of those can be written in such a way that the same inline assembly can be used to generate both 32 bit and 64 bit code. For ffs and fls, x86_64 unconditionally used the cmov instruction and i386 unconditionally used a conditional branch over a mov instruction. In the current patch I chose to select the version based on the availability of the cmov instruction instead. A small detail here is that x86_64 did not previously set CONFIG_X86_CMOV=y. Improved comments for ffs, ffz, fls and variations. Signed-off-by: Alexander van Heukelum <heukelum@fastmail.fm> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-26x86, generic: optimize find_next_(zero_)bit for small constant-size bitmapsAlexander van Heukelum
This moves an optimization for searching constant-sized small bitmaps form x86_64-specific to generic code. On an i386 defconfig (the x86#testing one), the size of vmlinux hardly changes with this applied. I have observed only four places where this optimization avoids a call into find_next_bit: In the functions return_unused_surplus_pages, alloc_fresh_huge_page, and adjust_pool_surplus, this patch avoids a call for a 1-bit bitmap. In __next_cpu a call is avoided for a 32-bit bitmap. That's it. On x86_64, 52 locations are optimized with a minimal increase in code size: Current #testing defconfig: 146 x bsf, 27 x find_next_*bit text data bss dec hex filename 5392637 846592 724424 6963653 6a41c5 vmlinux After removing the x86_64 specific optimization for find_next_*bit: 94 x bsf, 79 x find_next_*bit text data bss dec hex filename 5392358 846592 724424 6963374 6a40ae vmlinux After this patch (making the optimization generic): 146 x bsf, 27 x find_next_*bit text data bss dec hex filename 5392396 846592 724424 6963412 6a40d4 vmlinux [ tglx@linutronix.de: build fixes ] Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-26x86: change x86 to use generic find_next_bitAlexander van Heukelum
The versions with inline assembly are in fact slower on the machines I tested them on (in userspace) (Athlon XP 2800+, p4-like Xeon 2.8GHz, AMD Opteron 270). The i386-version needed a fix similar to 06024f21 to avoid crashing the benchmark. Benchmark using: gcc -fomit-frame-pointer -Os. For each bitmap size 1...512, for each possible bitmap with one bit set, for each possible offset: find the position of the first bit starting at offset. If you follow ;). Times include setup of the bitmap and checking of the results. Athlon Xeon Opteron 32/64bit x86-specific: 0m3.692s 0m2.820s 0m3.196s / 0m2.480s generic: 0m2.622s 0m1.662s 0m2.100s / 0m1.572s If the bitmap size is not a multiple of BITS_PER_LONG, and no set (cleared) bit is found, find_next_bit (find_next_zero_bit) returns a value outside of the range [0, size]. The generic version always returns exactly size. The generic version also uses unsigned long everywhere, while the x86 versions use a mishmash of int, unsigned (int), long and unsigned long. Using the generic version does give a slightly bigger kernel, though. defconfig: text data bss dec hex filename x86-specific: 4738555 481232 626688 5846475 5935cb vmlinux (32 bit) generic: 4738621 481232 626688 5846541 59360d vmlinux (32 bit) x86-specific: 5392395 846568 724424 6963387 6a40bb vmlinux (64 bit) generic: 5392458 846568 724424 6963450 6a40fa vmlinux (64 bit) Signed-off-by: Alexander van Heukelum <heukelum@fastmail.fm> Signed-off-by: Ingo Molnar <mingo@elte.hu>

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.

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.
