* | x86: Set context.vdso before installing the mappingPeter Zijlstra2009-06-051-2/+5
|/ | | | | | | | | | | | | | | | In order to make arch_vma_name() work from inside install_special_mapping() we need to set the context.vdso before calling it. ( This is needed for performance counters to be able to track this special executable area. ) Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul Mackerras <paulus@samba.org> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> LKML-Reference: <new-submission> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, mm: rename TASK_SIZE64 => TASK_SIZE_MAXIngo Molnar2009-02-211-2/+2
| | | | | | | | | | | | | Impact: cleanup Rename TASK_SIZE64 to TASK_SIZE_MAX, and provide the define on 32-bit too. (mapped to TASK_SIZE) This allows 32-bit code to make use of the (former-) TASK_SIZE64 symbol as well, in a clean way.

* [S390] arch_setup_additional_pages argumentsMartin Schwidefsky2008-12-251-1/+1
| | | | | | | | | | | | | | | | arch_setup_additional_pages currently gets two arguments, the binary format descripton and an indication if the process uses an executable stack or not. The second argument is not used by anybody, it could be removed without replacement. What actually does make sense is to pass an indication if the process uses the elf interpreter or not. The glibc code will not use anything from the vdso if the process does not use the dynamic linker, so for statically linked binaries the architecture backend can choose not to map the vdso.

* x86: fix two modpost warningsJan Beulich2008-07-181-5/+6
| | | | | | | | | | Even though it's only the difference of the two __initdata symbols that's being calculated, modpost still doesn't like this. So rather calculate the size once in an __init function and store it for later use. Signed-off-by: Jan Beulich <jbeulich@novell.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>

* x86 vDSO: use vdso-syms.ldsRoland McGrath2008-01-301-11/+7
| | | | | | | | | | | | | | | This patch changes the kernel's references to addresses in the vDSO image to be based on the symbols defined by vdso-syms.lds instead of the old vdso-syms.o symbols. This is all wrapped up in a macro defined by the new asm-x86/vdso.h header; that's the only place in the kernel source that has to know the details of the scheme for getting vDSO symbol values.
