Mark __cerror as hidden to avoid using the PLT. This is required for new
binutils where the PLT stubs now use %t1 (%r22) which is used to pass
the errno to __cerror.

Add a space before any non-nullified instruction. NFCI.

Remove unnecesary #define/#undef _LOCORE

Move to a flat space register convention. %sr[4-7] are all now the space
number allocated to the process. gcc produces (slightly) better code
with this convention.

Retain backwards compatiblity.

Welcome to 6.99.36

Whitespace.

branches: 1.7.6; 1.7.12;
Follow upstream license changes for files with Michael Shalayeff's
copyright. In most cases, this means dropping the 3rd and 4th clauses.

Generate correct unwind info for syscall stubs by using LEAF_ENTRY instead
of ENTRY(foo,0) so that gdb can backtrace through the stubs.

branches: 1.5.16;
Add a cerror.S and re-work various syscalls and SYS.h to use __cerror.

With help from the OpenBSD version of SYS.h.

Update to new assmbler needs. Add getcontext.S stub.

Remove "_THREAD_SAFE" stuff that is not used on NetBSD.

Changes to allow libc to compile as PIC on the hppa.

Added hppa support (some of it incomplete) to lib/csu, lib/libc,
and lib/libkvm.
