 1.18  23-Apr-2021  simonb Merge the .text.* sections into the .text section on MIPS, SPARC and
SPARC64 as is done on all other ports. Mostly costmetic, but does mean
that main() now appears before the _etext symbol instead of after it.
 1.17  25-Aug-2015  uebayasi Don't expand unwanted symbols by cpp(1).
 1.16  24-Aug-2015  uebayasi Don't mention stab and DWARF sections, because these (poorly mtaintained)
lists only help to make them harder to read.

If those sections are found in inputs, they simply appear in outputs as
orphaned sections, sorted by section types and attributes.
 1.15  22-Aug-2015  uebayasi .rel/.rela should not be generated in kernels.
 1.14  22-Aug-2015  uebayasi .init/.fini/.ctors/.dtors should be irrelevant to kernels.
 1.13  21-Aug-2015  uebayasi I bet setting search-directory for ld.so is useless in any kernel.
 1.12  20-Aug-2015  uebayasi Indent with 2 spaces.
 1.11  01-Jun-2010  mjf branches: 1.11.18; 1.11.36;
Add __cacheline_aligned and __read_mostly annotations.

These annotations help to mitigate false sharing on multiprocessor
systems.

Variables annotated with __cacheline_aligned are placed into the
.data.cacheline_aligned section in the kernel. Each item in this
section is aligned on a cachline boundary - this avoids false
sharing. Highly contended global locks are a good candidate for
__cacheline_aligned annotation.

Variables annotated with __read_mostly are packed together tightly
into a .data.read_mostly section in the kernel. The idea here is that
we can pack infrequently modified data items into a cacheline and
avoid having to purge the cache, which would happen if read mostly
data and write mostly data shared a cachline. Initialisation variables
are a prime candiate for __read_mostly annotations.
 1.10  17-Oct-2007  garbled branches: 1.10.20; 1.10.40; 1.10.42;
Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.
 1.9  04-Jun-2007  chs branches: 1.9.10;
instead of specifying the start of the data section in the makefile,
just round it up to the next 4MB boundary in the ldscript.
this prevents parts of the kernel-image range from being left unmapped.
fixes PR 36388.
 1.8  05-Dec-2006  martin branches: 1.8.6; 1.8.8; 1.8.14;
Enable the .note.netbsd section
 1.7  11-Dec-2005  christos branches: 1.7.20; 1.7.22; 1.7.24; 1.7.26;
merge ktrace-lwp.
 1.6  24-May-2004  martin branches: 1.6.12;
Back to SIZEOF_HEADERS.
 1.5  23-May-2004  martin Use 1024 instead of SIZEOF_HEADERS for now.
 1.4  16-May-2002  thorpej branches: 1.4.2; 1.4.10;
* Add "pcitag_t *pba_bridgetag" to pci_attach_args. This is set to
NULL for root PCI busses. For busses behind a bridge, it points to
a persistent copy of the bridge's pcitag_t. This can be very useful
for machine-dependent PCI bus enumeration code.
* Implement a machine-dependent pci_enumerate_bus() for sparc64 which
uses OFW device nodes to enumerate the bus. When a PCI bus that is
behind a bridge is attached, pci_attach_hook() allocates a new PCI
chipset tag for the new bus and sets it's "curnode" to the OFW node
of the bridge. This is used as a starting point when enumerating
that bus. Root busses get the OFW node of the host bridge (psycho).
* Garbage-collect "ofpci" and "ofppb" from the sparc64 port.
 1.3  06-May-2002  eeh Provide pci_cd if needed.
 1.2  04-Mar-2001  mrg branches: 1.2.4; 1.2.6; 1.2.10;

GDB changes:
- delete gdb53
- enable gdb6 on all architectures
- add support for amd64 crash dumps
- add support for sparc64 crash dumps
- add support for /proc pid to executable filename for all archs
- enable thread support for all architectures
- add a note section to kernels to all platforms
- support detection/unwinding of signals for most architectures.
- Fix PTHREAD_UCONTEXT_TO_REG / PTHREAD_REG_TO_UCONTEXT on sh3.
- Apply fix from binutils-current so that sparc gdb can be cross built
on a 64bit host.
SA/pthread changes:
Pre-allocate memory needed for event delivery. Eliminates dropped
interrupts under load.
Deliver intra-process signals to running threads
Eliminate some deadlock scenarios
Fix intra-process signal delivery when delivering to a thread waiting

 1.7.24.1  05-Jun-2007  bouyer Pull up following revision(s) (requested by martin in ticket #700):
sys/arch/sparc64/conf/kern32.ldscript: revision 1.8
sys/arch/sparc64/conf/kern.ldscript: revision 1.9
sys/arch/sparc64/conf/Makefile.sparc64: revision 1.63
instead of specifying the start of the data section in the makefile,
just round it up to the next 4MB boundary in the ldscript.
this prevents parts of the kernel-image range from being left unmapped.
fixes PR 36388.
