maya | put .note.Xen into PT_NOTE
this is where grub 2.02 and possibly other things expect
to find it.
Fixes booting with grub2 on prgmr.com.
|
| 1.16 |
| 24-Jun-2018 |
maxv | Sync the ld scripts:
* Force a PAGE_SIZE alignment of .bss on i386. Normally that's not
required since the bootloader ensures page alignment, but let's be
safe. Same on Xen-i386.
* Fill the .text section padding with int3 instructions on Xen kernels,
to prevent FALLTHROUGHs if a pointer goes crazy, same as native.

maxv | branches: 1.15.2;
Implement a real hotpatch feature.
Define a HOTPATCH() macro, that puts a label and additional information
in the new .rodata.hotpatch kernel section. In patch.c, scan the section
and patch what needs to be. Now it is possible to hotpatch the content of
a macro.
SMAP is switched to use this new system; this saves a call+ret in each
kernel entry/exit point.
Many other operating systems do the same.

| 1.14 |
| 25-Jun-2017 |
bouyer | Restore alignement of _end to rev 1.12: this is where the Xen loader
puts the symbol table and should not be changed (maybe we should change
this symbol name).
keep kernel_end PAGE-aligned.
Makes ddb work again on Xen/i386

| 1.13 |
| 02-Aug-2016 |
maxv | branches: 1.13.8;
Align the segments properly, and split text+rodata in two separate segments
on Xen.
|
| 1.12 |
| 13-May-2016 |
maxv | branches: 1.12.2;
Xen therefore uses x86/db_memrw.c, as I suspected. Define __rodata_start
in the Xen ld scripts, so that it can compile. We put the __rodata_start
definition right before __data_start, for it to appear as dead code, since
the rodata segment is not yet mapped independently on Xen.
|
| 1.11 |
| 12-May-2016 |
maxv | KNF the Xen ld scripts on x86.
|
| 1.10 |
| 25-Aug-2015 |
uebayasi | Replace a constant in ldscript.
|
| 1.9 |
| 22-Aug-2015 |
uebayasi | Don't need to specify OUTPUT_FORMAT/OUTPUT_ARCH in linker scripts.
|
| 1.8 |
| 20-Aug-2015 |
uebayasi | Simplify these by doing AT () relocation once.
|
| 1.7 |
| 20-Aug-2015 |
uebayasi | Indent with 2 spaces.

uebayasi | branches: 1.6.2;
Revert previous per joerg@'s request.
According to him, exposing .data.{read_mostly,cacheline_aligned} is
intentional so that people can easily see which variables are optimized.
|
| 1.5 |
| 01-Nov-2014 |
uebayasi | amd64, i386: Don't expose .data.{read_mostly,cacheline_aligned} sections
|
| 1.4 |
| 23-Sep-2012 |
chs | sync ldscripts; add cacheline_aligned and read_mostly handling
to the non-default ones.
|
| 1.3 |
| 18-Oct-2007 |
yamt | branches: 1.3.54; 1.3.60; 1.3.64;
merge yamt-x86pmap branch.
- reduce differences between amd64 and i386. notably, share pmap.c
between them. it makes several i386 pmap improvements available to
amd64, including tlb shootdown reduction and bug fixes from Stephan Uphoff.
- implement deferred pmap switching for amd64.
- remove LARGEPAGES option. always use large pages if available.
also, make it work on amd64.

Give Xen its own linker script, which does not set the physical load address
specially. In Xen, the system is already in virtual mode when the kernel is
started, so the old behavior of setting physical address to virtual address
was actually correct, and the previous change made NetBSD/Xen kernels
unbootable.
Pointed out, explained and tested by <bouyer>.

yamt | - move etext before rodata. define __data_start at the start of
.data section and use it instead of etext where appropriate.
- put .rodata.* into .rodata section as well.
- pmap_bootstrap: don't assume NBPD_L2 alignment.
- pmap_bootstrap: if DEBUG, print how many large pages and normal pages are
used to map kernel text.

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.
