sjg 13b51c6c09 Var_Set: avoid SIGSEGV if val is NULL 
A NULL val is handled gracefully (by VarAdd) when
var is not previously set, so we ought not crash
the second time.

maxv 71e53827d1 Declare check_swapgs in an ASM macro. No real functional change. 2018-02-17 21:05:58 +00:00
maxv 8f95f7b82b Use ASM macros for the rest of the entry points. No real functional 
change. Now the format of the entry points is:

	.macro	TRAP_ENTRY_POINT_xx	arg1,arg2,arg3
		...the asm code...
	.endm

		TEXT_USER_BEGIN
	TRAP_ENTRY_POINT_xx	arg1,arg2,arg3
		TEXT_USER_END

maxv badec0a023 Declare and use TRAP_ENTRY_POINT_DNA. This time we don't give an is_ztrap 
argument, because the macro is tied to the entry point, and it would be
wrong to suggest the paramater is controllable. No real functional change.

maxv f07054b64f Now that [Z]TRAP and [Z]TRAP_NJ are identical, put back the

instructions for Xen, and remove [Z]TRAP_NJ.

change.

maxv 458f24f8d8 Define legacy_stubs in a macro. 2018-02-17 19:26:20 +00:00

files.
 2018-02-17 19:10:18 +00:00
maxv 6e7355e588 Rename i8259_stubs -> legacy_stubs. We will want the entries to have the 
same name, eg:

	legacy_stubs
		-> Xintr_legacy0, Xrecurse_legacy0, Xresume_legacy0
		-> Xintr_legacy1, Xrecurse_legacy1, Xresume_legacy1

maxv 9779fa67f8 Add svs_init. This is where we will detect the CPU and decide whether 
to turn SVS on or not.

Add svs_pgg_update to dynamically add/remove PG_G from all the kernel
pages. Use it now.

kamil 19baa3e0e8 Improve _UC_MACHINE_FP() for SPARC/SPARC64 
Introduce a static inline function _uc_machine_fp() that contains improved
caluclation of a frame pointer.

Algorithm:

  uptr *stk_ptr;
#  if defined (__arch64__)
  stk_ptr = (uptr *) (*sp + 2047);
#  else
  stk_ptr = (uptr *) *sp;
#  endif
  *bp = stk_ptr[15];

joerg f71f5c795a Drop explicit loop prefix. GAS doesn't care and LLVM doesn't support it. 
Drop the need for assembling with GAS. While LLVM is using a suboptimal
encoding of for hard-coded memory writes, it shouldn't affect
functionality. It just wastes three bytes with extra prefixes.

kamil 655627c899 Stop installing dbregs.h 
This is now kernel-only header. The behavior is well specified by the CPU
documents and we don't introduce changes to it.

sevan 14e1124894 Remove mention of DDB_ONPANIC=2, ddb.dumpstack which is enabled by default now handles back traces on panic. 2018-02-17 02:11:00 +00:00
sevan f32d105ac2 With the introduction of ddb.dumpstack which is enabled by default, we no longer 
need to explicitly set DDB_COMMANDONENTER to run a trace.

sevan ef01774665 Opt to print a backtrace on panic by default with the intention of improving bug reports. 
Instead of relying on ddb.onpanic=2, introduce a new sysctl called dumpstack to handle this.
