um: Set __HAVE_ARCH_GATE_AREA for i386

2011-07-26T03:57:13+00:00

When UML is unable to reuse the host's vDSO FIXADDR_USER_START is zero. To handle this special case correclty we have to implement custom gate area helper methods. Signed-off-by: Richard Weinberger Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

um: Make rwsem.S depend on CONFIG_RWSEM_XCHGADD_ALGORITHM

2011-07-22T21:06:30+00:00

rwsem.S can only be used with CONFIG_RWSEM_XCHGADD_ALGORITHM. This unbreaks the UML build on i386.

x86: Unify rwsem assembly implementation

2011-07-21T07:03:32+00:00

Rather than having two functionally identical implementations for 32- and 64-bit configurations, use the previously extended assembly abstractions to fold the rwsem two implementations into a shared one.

um: mdd support for 64 bit atomic operations

2011-04-28T18:28:21+00:00

This adds support for 64 bit atomic operations on 32 bit UML systems. XFS needs them since 2.6.38. $ make ARCH=um SUBARCH=i386 ...

elf coredump: replace ELF_CORE_EXTRA_* macros by functions

2010-03-06T19:26:45+00:00

elf_core_dump() and elf_fdpic_core_dump() use #ifdef and the corresponding macro for hiding _multiline_ logics in functions. This patch removes #ifdef and replaces ELF_CORE_EXTRA_* by corresponding functions. For architectures not implemeonting ELF_CORE_EXTRA_*, we use weak functions in order to reduce a range of modification. This cleanup is for my next patches, but I think this cleanup itself is worth doing regardless of my firnal purpose.

x86, UML: remove x86-specific implementations of find_first_bit

2008-04-26T17:21:17+00:00

x86 has been switched to the generic versions of find_first_bit and find_first_zero_bit, but the original versions were retained. This patch just removes the now unused x86-specific versions. also update UML. Signed-off-by: Alexander van Heukelum Signed-off-by: Ingo Molnar
