Note: DEBUG checks will not allow accesses to the hole between
text and data segments, so you may need to update programs that
use libkvm before relocating the start of kernel data.
* Really pass PSR ICC bits instead of raw CCR.
* Don't touch ASI and FPRS, which are not part of the 32-bit mcontext.
Also, correct printf conversions in svr4_printmcontext.
them define __HAVE_PCIIDE_MACHDEP_COMPAT_INTR_ESTABLISH
in pci_machdep.h and pciide_map_compat_intr() only calls
pciide_machdep_compat_intr_establish() if that preprocessor
define exists.
Ports that don't need to do this no longer need to supply a
dummy function.
pmap_growkernel() on large memory machines. at this point we've already
called uvm_page_init(), so we can no longer use uvm_page_physget().
but the flag we use to decide whether to use uvm_page_physget() vs.
uvm_pagealloc() is only set at the end of pmap_init(), so we use
uvm_page_physget() anyway. switch to using uvm.page_init_done to decide
how to allocate pages, since that's the real indicator of when we have to
change methods.
* rename sigcontext.sc_tstate to sc_psr, since this is how it is known to
the 32-bit API, and also used for;
* don't try to squeeze the tstate into it, just emulate the ICC bits.
Per discussion with Eduardo.
each vm_page structure. Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM. These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.
This deprecates struct pmap_physseg. As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.
Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now). Changes to other pmap
modules will follow.
