svn commit: r199488 - projects/ppc64/sys/compat/freebsd32

[Nathan Whitehorn]

Author: nwhitehorn
Date: Wed Nov 18 17:47:40 2009
New Revision: 199488
URL: http://svn.freebsd.org/changeset/base/199488

Log:
  Add padding for arguments passed as 64-bit types. The 32-bit SVR4 ABI
  requires that 64-bit values be passed starting only in odd-numbered
  registers. This lets me bring a PPC64 kernel up multiuser!
  
  Note that this is a hack (see: changes to an autogenerated file). Better
  solutions will hopefully be forthcoming.
