Description Mark Langsdorf 2003-08-13 16:46:00 EDT
Description of problem:
/usr/include/linux/personality.h and /usr/src/linux/include/linux/personality.h
differ: the kernel version includes a new #define to describe 32-bit systems
with only 3 GB of addressable memory (called ADDR_LIMIT_3GB).  The glibc 
include files should match the kernel version.

Version-Release number of selected component (if applicable):

FWIW this isn't in the Taroon kernel itself, either - I suppose it needs to get in there before 
Comment 2 Mark Langsdorf 2003-08-13 16:55:21 EDT
There are sound technical and business reasons to support the 3GB address limit,
so please add it to the Taroon kernel.
Comment 3 David Woodhouse 2005-04-15 09:05:01 EDT
This is present in RHEL4 personality.h. If the functionality really is required
in a Taroon kernel update, please reopen a feature request through appropriate
channels, and we'll add the define to userspace personality.h if/when the kernel
starts to support it.
