net: pse-pd: Remove is_enabled callback from drivers

The is_enabled callback is now redundant as the admin_state can be obtained directly from the driver and provides the same information. To simplify functionality, the core will handle this internally, making the is_enabled callback unnecessary at the driver level. Remove the callback from all drivers.

-   An AVANTI *might* be an XL, and an XL has only 27 bits of ISA address
-   that get passed through the PCI<->ISA bridge chip. So we've gotta use
-   both windows to max out the physical memory we can DMA to. Sigh...
-
-   If we try a window at 0 for 1GB as a work-around, we run into conflicts
-   with ISA/PCI bus memory which can't be relocated, like VGA aperture and
-   BIOS ROMs. So we must put the windows high enough to avoid these areas.
-
-   We put window 1 at BUS 64Mb for 64Mb, mapping physical 0 to 64Mb-1,
-   and window 2 at BUS 1Gb for 1Gb, mapping physical 0 to 1Gb-1.
-   Yes, this does map 0 to 64Mb-1 twice, but only window 1 will actually
-   be used for that range (via virt_to_bus()).
-
-   Note that we actually fudge the window 1 maximum as 48Mb instead of 64Mb,
-   to keep virt_to_bus() from returning an address in the first window, for
-   a data area that goes beyond the 64Mb first DMA window.  Sigh...
-   The fudge factor MUST match with <asm/dma.h> MAX_DMA_ADDRESS, but
-   we can't just use that here, because of header file looping... :-(
-
-   Window 1 will be used for all DMA from the ISA bus; yes, that does
-   limit what memory an ISA floppy or sound card or Ethernet can touch, but
-   it's also a known limitation on other platforms as well. We use the
-   same technique that is used on INTEL platforms with similar limitation:
-   set MAX_DMA_ADDRESS and clear some pages' DMAable flags during mem_init().
-   We trust that any ISA bus device drivers will *always* ask for DMAable
-   memory explicitly via kmalloc()/get_free_pages() flags arguments.
-
-   Note that most PCI bus devices' drivers do *not* explicitly ask for
-   DMAable memory; they count on being able to DMA to any memory they
-   get from kmalloc()/get_free_pages(). They will also use window 1 for
-   any physical memory accesses below 64Mb; the rest will be handled by
-   window 2, maxing out at 1Gb of memory. I trust this is enough... :-)
-
-   We hope that the area before the first window is large enough so that
-   there will be no overlap at the top end (64Mb). We *must* locate the
-   PCI cards' memory just below window 1, so that there's still the
-   possibility of being able to access it via SPARSE space. This is
-   important for cards such as the Matrox Millennium, whose Xserver
-   wants to access memory-mapped registers in byte and short lengths.
-
-   Note that the XL is treated differently from the AVANTI, even though
-   for most other things they are identical. It didn't seem reasonable to
-   make the AVANTI support pay for the limitations of the XL. It is true,
-   however, that an XL kernel will run on an AVANTI without problems.
-
-   %%% All of this should be obviated by the ability to route
-   everything through the iommu.

-/*
- * NOTE: The LCA uses a Host Address Extension (HAE) register to access
- *	 PCI addresses that are beyond the first 27 bits of address
- *	 space.  Updating the HAE requires an external cycle (and
- *	 a memory barrier), which tends to be slow.  Instead of updating
- *	 it on each sparse memory access, we keep the current HAE value
- *	 cached in variable cache_hae.  Only if the cached HAE differs
- *	 from the desired HAE value do we actually updated HAE register.
- *	 The HAE register is preserved by the interrupt handler entry/exit
- *	 code, so this scheme works even in the presence of interrupts.
- *
- * Dense memory space doesn't require the HAE, but is restricted to
- * aligned 32 and 64 bit accesses.  Special Cycle and Interrupt
- * Acknowledge cycles may also require the use of the HAE.  The LCA
- * limits I/O address space to the bottom 24 bits of address space,
- * but this easily covers the 16 bit ISA I/O address space.
- */
-
-/*
- * NOTE 2! The memory operations do not set any memory barriers, as
- * it's not needed for cases like a frame buffer that is essentially
- * memory-like.  You need to do them by hand if the operations depend
- * on ordering.
- *
- * Similarly, the port I/O operations do a "mb" only after a write
- * operation: if an mb is needed before (as in the case of doing
- * memory mapped I/O first, and then a port I/O operation to the same
- * device), it needs to be done by hand.
- *
- * After the above has bitten me 100 times, I'll give up and just do
- * the mb all the time, but right now I'm hoping this will work out.
- * Avoiding mb's may potentially be a noticeable speed improvement,
- * but I can't honestly say I've tested it.
- *
- * Handling interrupts that need to do mb's to synchronize to
- * non-interrupts is another fun race area.  Don't do it (because if
- * you do, I'll have to do *everything* with interrupts disabled,
- * ugh).

- * Jensen is special: the vector is 0x8X0 for EISA interrupt X, and
- * 0x9X0 for the local motherboard interrupts.
- *
- * Note especially that those local interrupts CANNOT be masked,
- * which causes much of the pain below...
- *
- *	0x660 - NMI
- *
- *	0x800 - IRQ0  interval timer (not used, as we use the RTC timer)
- *	0x810 - IRQ1  line printer (duh..)
- *	0x860 - IRQ6  floppy disk
- *
- *	0x900 - COM1
- *	0x920 - COM2
- *	0x980 - keyboard
- *	0x990 - mouse
- *
- * PCI-based systems are more sane: they don't have the local
- * interrupts at all, and have only normal PCI interrupts from
- * devices.  Happily it's easy enough to do a sane mapping from the
- * Jensen.
- * 
- * Note that this means that we may have to do a hardware
- * "local_op" to a different interrupt than we report to the rest of the
- * world.

+ * Remarks about the rationale behind the chosen mapping:
+ *
+ * - BPF_REG_{1,2,3,4} are the argument registers and must be mapped to
+ *   argument registers in ARCv2 ABI: r0-r7. The r7 registers is the last
+ *   argument register in the ABI. Therefore BPF_REG_5, as the fifth
+ *   argument, must be pushed onto the stack. This is a must for calling
+ *   in-kernel functions.
+ *
+ * - In ARCv2 ABI, the return value is in r0 for 32-bit results and (r1,r0)
+ *   for 64-bit results. However, because they're already used for BPF_REG_1,
+ *   the next available scratch registers, r8 and r9, are the best candidates
+ *   for BPF_REG_0. After a "call" to a(n) (in-kernel) function, the result
+ *   is "mov"ed to these registers. At a BPF_EXIT, their value is "mov"ed to
+ *   (r1,r0).
+ *   It is worth mentioning that scratch registers are the best choice for
+ *   BPF_REG_0, because it is very popular in BPF instruction encoding.
+ *
+ * - JIT_REG_TMP is an artifact needed to translate some BPF instructions.
+ *   Its life span is one single BPF instruction. Since during the
+ *   analyze_reg_usage(), it is not known if temporary registers are used,
+ *   it is mapped to ARC's scratch registers: r10 and r11. Therefore, they
+ *   don't matter in analysing phase and don't need saving. This temporary
+ *   register is added as yet another index in the bpf2arc array, so it will
+ *   unfold like the rest of registers during the code generation process.
+ *
+ * - Mapping of callee-saved BPF registers, BPF_REG_{6,7,8,9}, starts from
+ *   (r15,r14) register pair. The (r13,r12) is not a good choice, because
+ *   in ARCv2 ABI, r12 is not a callee-saved register and this can cause
+ *   problem when calling an in-kernel function. Theoretically, the mapping
+ *   could start from (r14,r13), but it is not a conventional ARCv2 register
+ *   pair. To have a future proof design, I opted for this arrangement.
+ *   If/when we decide to add ARCv2 instructions that do use register pairs,
+ *   the mapping, hopefully, doesn't need to be revisited.
