cc6fae1156 Pass the correct trapframe pointer to fork_exit - sp is trapframe-16. 2001-10-12 11:50:09 +00:00

5b341f5baf If the faulting instruction is a cmpxchg, then isr.w and isr.r will both 
be set. We need to check isr.w before isr.r so that we can correctly
handle a cmpxchg to a copy-on-write page.

This fixes the hang-after-fork problem for dynamically linked programs.

f334c8bff7 * Change the calling convention for execve so that it conforms to normal 
C calling conventions. This allows crt1.c to be written nearly without
  any inline assembler.
* Initialise cpu_model[] so that the hw.model sysctl works properly.

3da3249106 Dissociate ptrace from procfs. 
Until now, the ptrace syscall was implemented as a wrapper that called
various functions in procfs depending on which ptrace operation was
requested.  Most of these functions were themselves wrappers around
procfs_{read,write}_{,db,fp}regs(), with only some extra error checks,
which weren't necessary in the ptrace case anyway.

This commit moves procfs_rwmem() from procfs_mem.c into sys_process.c
(renaming it to proc_rwmem() in the process), and implements ptrace()
directly in terms of procfs_{read,write}_{,db,fp}regs() instead of
having it fake up a struct uio and then call procfs_do{,db,fp}regs().

It also moves the prototypes for procfs_{read,write}_{,db,fp}regs()
and proc_rwmem() from proc.h to ptrace.h, and marks all procfs files
except procfs_machdep.c as "optional procfs" instead of "standard".

e0e2fed358 * Use srlz.i to serialise changes to psr.ic 
* Don't enable psr.i at the same time as psr.dt and psr.ic

These changes improve stability considerably.

18819cbb5c o Change ia64_memory_address to explicitly take a u_int64_t 
o  Add memcpy_fromio, memcpy_io, memcpy_toio, memset_io,
   memsetw and memsetw_io. I'm not sure this is the right
   place for it, though.
