ARCv2: Support for ARCv2 ISA and HS38x cores

2015-06-22T08:36:55+00:00

The notable features are:
    - SMP configurations of upto 4 cores with coherency
    - Optional L2 Cache and IO-Coherency
    - Revised Interrupt Architecture (multiple priorites, reg banks,
        auto stack switch, auto regfile save/restore)
    - MMUv4 (PIPT dcache, Huge Pages)
    - Instructions for
	* 64bit load/store: LDD, STD
	* Hardware assisted divide/remainder: DIV, REM
	* Function prologue/epilogue: ENTER_S, LEAVE_S
	* IRQ enable/disable: CLRI, SETI
	* pop count: FFS, FLS
	* SETcc, BMSKN, XBFU...

  arc: copy_thread(): rename 'arg' argument to 'kthread_arg'

whack-a-mole: no need to set_fs(USER_DS) in {start,flush}_thread()

2015-04-12T02:24:31+00:00

flush_old_exec() has already done that.  Back on 2011 a bunch of
instances like that had been kicked out, but that hadn't taken
care of then-out-of-tree architectures, obviously, and they served
as reinfection vector...

arc: copy_thread(): rename 'arg' argument to 'kthread_arg'

2015-03-31T05:50:51+00:00

The 'arg' argument to copy_thread() is only ever used when forking a new
kernel thread. Hence, rename it to 'kthread_arg' for clarity.

ARC: Fix thread_saved_pc()

2015-02-27T05:29:34+00:00

The old implementation assumed that SP at the time of __switch_to() is
right above pt_regs which is almost certainly not the case as there will
be some stack build up between entry into kernel and leading up to
__switch_to
