  * <asm/atariints.h>): Autovector interrupts are 1..7, then follow ST-MFP,
  * TT-MFP, SCC, and finally VME interrupts. Vector numbers for the latter can
  * be allocated by atari_register_vme_int().
- *
- * Each interrupt can be of three types:
- *
- *  - SLOW: The handler runs with all interrupts enabled, except the one it
- *    was called by (to avoid reentering). This should be the usual method.
- *    But it is currently possible only for MFP ints, since only the MFP
- *    offers an easy way to mask interrupts.
- *
- *  - FAST: The handler runs with all interrupts disabled. This should be used
- *    only for really fast handlers, that just do actions immediately
- *    necessary, and let the rest do a bottom half or task queue.
- *
- *  - PRIORITIZED: The handler can be interrupted by higher-level ints
- *    (greater IPL, no MFP priorities!). This is the method of choice for ints
- *    which should be slow, but are not from a MFP.
- *
- * The feature of more than one handler for one int source is still there, but
- * only applicable if all handers are of the same type. To not slow down
- * processing of ints with only one handler by the chaining feature, the list
- * calling function atari_call_irq_list() is only plugged in at the time the
- * second handler is registered.
- *
- * Implementation notes: For fast-as-possible int handling, there are separate
- * entry points for each type (slow/fast/prio). The assembler handler calls
- * the irq directly in the usual case, no C wrapper is involved. In case of
- * multiple handlers, atari_call_irq_list() is registered as handler and calls
- * in turn the real irq's. To ease access from assembler level to the irq
- * function pointer and accompanying data, these two are stored in a separate
- * array, irq_handler[]. The rest of data (type, name) are put into a second
- * array, irq_param, that is accessed from C only. For each slow interrupt (32
- * in all) there are separate handler functions, which makes it possible to
- * hard-code the MFP register address and value, are necessary to mask the
- * int. If there'd be only one generic function, lots of calculations would be
- * needed to determine MFP register and int mask from the vector number :-(
- *
- * Furthermore, slow ints may not lower the IPL below its previous value
- * (before the int happened). This is needed so that an int of class PRIO, on
- * that this int may be stacked, cannot be reentered. This feature is
- * implemented as follows: If the stack frame format is 1 (throwaway), the int
- * is not stacked, and the IPL is anded with 0xfbff, resulting in a new level
- * 2, which still blocks the HSYNC, but no interrupts of interest. If the
- * frame format is 0, the int is nested, and the old IPL value can be found in
- * the sr copy in the frame.

+/*
+ * On Macs with a genuine VIA chip there is no way to mask an individual slot
+ * interrupt. This limitation also seems to apply to VIA clone logic cores in
+ * Quadra-like ASICs. (RBV and OSS machines don't have this limitation.)
+ *
+ * We used to fake it by configuring the relevent VIA pin as an output
+ * (to mask the interrupt) or input (to unmask). That scheme did not work on
+ * (at least) the Quadra 700. A NuBus card's /NMRQ signal is an open-collector
+ * circuit (see Designing Cards and Drivers for Macintosh II and Macintosh SE,
+ * p. 10-11 etc) but VIA outputs are not (see datasheet).
+ *
+ * Driving these outputs high must cause the VIA to source current and the
+ * card to sink current when it asserts /NMRQ. Current will flow but the pin
+ * voltage is uncertain and so the /NMRQ condition may still cause a transition
+ * at the VIA2 CA1 input (which explains the lost interrupts). A side effect
+ * is that a disabled slot IRQ can never be tested as pending or not.
+ *
+ * Driving these outputs low doesn't work either. All the slot /NMRQ lines are
+ * (active low) OR'd together to generate the CA1 (aka "SLOTS") interrupt (see
+ * The Guide To Macintosh Family Hardware, 2nd edition p. 167). If we drive a
+ * disabled /NMRQ line low, the falling edge immediately triggers a CA1
+ * interrupt and all slot interrupts after that will generate no transition
+ * and therefore no interrupt, even after being re-enabled.
+ *
+ * So we make the VIA port A I/O lines inputs and use nubus_disabled to keep
+ * track of their states. When any slot IRQ becomes disabled we mask the CA1
+ * umbrella interrupt. Only when all slot IRQs become enabled do we unmask
+ * the CA1 interrupt. It must remain enabled even when cards have no interrupt
+ * handler registered. Drivers must therefore disable a slot interrupt at the
+ * device before they call free_irq (like shared and autovector interrupts).
+ *
+ * There is also a related problem when MacOS is used to boot Linux. A network
+ * card brought up by a MacOS driver may raise an interrupt while Linux boots.
+ * This can be fatal since it can't be handled until the right driver loads
+ * (if such a driver exists at all). Apparently related to this hardware
+ * limitation, "Designing Cards and Drivers", p. 9-8, says that a slot
+ * interrupt with no driver would crash MacOS (the book was written before
+ * the appearance of Macs with RBV or OSS).

+ * On BookE with RELOCATABLE (RELOCATABLE_PPC32)
+ *
+ *   With RELOCATABLE_PPC32,  we support loading the kernel at any physical 
+ *   address without any restriction on the page alignment.
+ *
+ *   We find the runtime address of _stext and relocate ourselves based on 
+ *   the following calculation:
+ *
+ *  	  virtual_base = ALIGN_DOWN(KERNELBASE,256M) +
+ *  				MODULO(_stext.run,256M)
+ *   and create the following mapping:
+ *
+ * 	  ALIGN_DOWN(_stext.run,256M) => ALIGN_DOWN(KERNELBASE,256M)
+ *
+ *   When we process relocations, we cannot depend on the
+ *   existing equation for the __va()/__pa() translations:
+ *
+ * 	   __va(x) = (x)  - PHYSICAL_START + KERNELBASE
+ *
+ *   Where:
+ *   	 PHYSICAL_START = kernstart_addr = Physical address of _stext
+ *  	 KERNELBASE = Compiled virtual address of _stext.
+ *
+ *   This formula holds true iff, kernel load address is TLB page aligned.
+ *
+ *   In our case, we need to also account for the shift in the kernel Virtual 
+ *   address.
+ *
+ *   E.g.,
+ *
+ *   Let the kernel be loaded at 64MB and KERNELBASE be 0xc0000000 (same as PAGE_OFFSET).
+ *   In this case, we would be mapping 0 to 0xc0000000, and kernstart_addr = 64M

+ *   Now __va(1MB) = (0x100000) - (0x4000000) + 0xc0000000
+ *                 = 0xbc100000 , which is wrong.
+ *
+ *   Rather, it should be : 0xc0000000 + 0x100000 = 0xc0100000
+ *      	according to our mapping.
+ *
+ *   Hence we use the following formula to get the translations right:
+ *
+ * 	  __va(x) = (x) - [ PHYSICAL_START - Effective KERNELBASE ]
+ *
+ * 	  Where :
+ * 		PHYSICAL_START = dynamic load address.(kernstart_addr variable)
+ * 		Effective KERNELBASE = virtual_base =
+ * 				     = ALIGN_DOWN(KERNELBASE,256M) +
+ * 						MODULO(PHYSICAL_START,256M)
+ *
+ * 	To make the cost of __va() / __pa() more light weight, we introduce
+ * 	a new variable virt_phys_offset, which will hold :
+ *
+ * 	virt_phys_offset = Effective KERNELBASE - PHYSICAL_START
+ * 			 = ALIGN_DOWN(KERNELBASE,256M) - 
+ * 			 	ALIGN_DOWN(PHYSICALSTART,256M)
+ *
+ * 	Hence :
+ *
+ * 	__va(x) = x - PHYSICAL_START + Effective KERNELBASE
+ * 		= x + virt_phys_offset
+ *
+ * 		and
+ * 	__pa(x) = x + PHYSICAL_START - Effective KERNELBASE
+ * 		= x - virt_phys_offset
+ * 		
  * On non-Book-E PPC64 PAGE_OFFSET and MEMORY_START are constants so use
  * the other definitions for __va & __pa.

+ * The processor and its L2 cache cause the icswx instruction to
+ * generate a COP_REQ transaction on PowerBus. The transaction has no
+ * address, and the processor does not perform an MMU access to
+ * authenticate the transaction. The command portion of the PowerBus
+ * COP_REQ transaction includes the LPAR_ID (LPID) and the coprocessor
+ * Process ID (PID), which the coprocessor compares to the authorized
+ * LPID and PID held in the coprocessor, to determine if the process
+ * is authorized to generate the transaction.  The data of the COP_REQ
+ * transaction is 128-byte or less in size and is placed in cacheable
+ * memory on a 128-byte cache line boundary.
+ *
+ * The task to use a coprocessor should use use_cop() to mark the use
+ * of the Coprocessor Type (CT) and context switching. On a server
+ * class processor, the PID register is used only for coprocessor
+ * management + * and so a coprocessor PID is allocated before
+ * executing icswx + * instruction. Drop_cop() is used to free the
+ * coprocessor PID.
+ *
+ * Example:
+ * Host Fabric Interface (HFI) is a PowerPC network coprocessor.
+ * Each HFI have multiple windows. Each HFI window serves as a
+ * network device sending to and receiving from HFI network.
+ * HFI immediate send function uses icswx instruction. The immediate
+ * send function allows small (single cache-line) packets be sent
+ * without using the regular HFI send FIFO and doorbell, which are
+ * much slower than immediate send.
+ *
+ * For each task intending to use HFI immediate send, the HFI driver
+ * calls use_cop() to obtain a coprocessor PID for the task.
+ * The HFI driver then allocate a free HFI window and save the
+ * coprocessor PID to the HFI window to allow the task to use the
+ * HFI window.
+ *
+ * The HFI driver repeatedly creates immediate send packets and
+ * issues icswx instruction to send data through the HFI window.
+ * The HFI compares the coprocessor PID in the CPU PID register
+ * to the PID held in the HFI window to determine if the transaction
+ * is allowed.
+ *
+ * When the task to release the HFI window, the HFI driver calls
+ * drop_cop() to release the coprocessor PID.

- * The processor and its L2 cache cause the icswx instruction to
- * generate a COP_REQ transaction on PowerBus. The transaction has
- * no address, and the processor does not perform an MMU access
- * to authenticate the transaction. The command portion of the
- * PowerBus COP_REQ transaction includes the LPAR_ID (LPID) and
- * the coprocessor Process ID (PID), which the coprocessor compares
- * to the authorized LPID and PID held in the coprocessor, to determine
- * if the process is authorized to generate the transaction.
- * The data of the COP_REQ transaction is 128-byte or less and is
- * placed in cacheable memory on a 128-byte cache line boundary.
- *
- * The task to use a coprocessor should use use_cop() to allocate
- * a coprocessor PID before executing icswx instruction. use_cop()
- * also enables the coprocessor context switching. Drop_cop() is
- * used to free the coprocessor PID.
- *
- * Example:
- * Host Fabric Interface (HFI) is a PowerPC network coprocessor.
- * Each HFI have multiple windows. Each HFI window serves as a
- * network device sending to and receiving from HFI network.
- * HFI immediate send function uses icswx instruction. The immediate
- * send function allows small (single cache-line) packets be sent
- * without using the regular HFI send FIFO and doorbell, which are
- * much slower than immediate send.
- *
- * For each task intending to use HFI immediate send, the HFI driver
- * calls use_cop() to obtain a coprocessor PID for the task.
- * The HFI driver then allocate a free HFI window and save the
- * coprocessor PID to the HFI window to allow the task to use the
- * HFI window.
- *
- * The HFI driver repeatedly creates immediate send packets and
- * issues icswx instruction to send data through the HFI window.
- * The HFI compares the coprocessor PID in the CPU PID register
- * to the PID held in the HFI window to determine if the transaction
- * is allowed.
- *
- * When the task to release the HFI window, the HFI driver calls
- * drop_cop() to release the coprocessor PID.
