-* 4 use cases of Alchemy GPIOS:
-*(1) GPIOLIB=y, ALCHEMY_GPIO_INDIRECT=y:
-*	Board must register gpiochips.
-*(2) GPIOLIB=y, ALCHEMY_GPIO_INDIRECT=n:
-*	A gpiochip for the 75 GPIOs is registered.
-*
-*(3) GPIOLIB=n, ALCHEMY_GPIO_INDIRECT=y:
-*	the boards' gpio.h must provide the linux gpio wrapper functions,
-*
-*(4) GPIOLIB=n, ALCHEMY_GPIO_INDIRECT=n:
-*	inlinable gpio functions are provided which enable access to the
-*	Au1300 gpios only by using the numbers straight out of the data-
-*	sheets.
-
-* Cases 1 and 3 are intended for boards which want to provide their own
-* GPIO namespace and -operations (i.e. for example you have 8 GPIOs
-* which are in part provided by spare Au1300 GPIO pins and in part by
-* an external FPGA but you still want them to be accessible in linux
-* as gpio0-7. The board can of course use the alchemy_gpioX_* functions
-* as required).

- * SMP/VPE-safe functions to access "registers" (see note).
- *
- * NOTES:
-* - These macros use ll/sc instructions, so it is your responsibility to
- * ensure these are available on your platform before including this file.
- * - The MIPS32 spec states that ll/sc results are undefined for uncached
- * accesses. This means they can't be used on HW registers accessed
- * through kseg1. Code which requires these macros for this purpose must
- * front-end the registers with cached memory "registers" and have a single
- * thread update the actual HW registers.
- * - A maximum of 2k of code can be inserted between ll and sc. Every
- * memory accesses between the instructions will increase the chance of
- * sc failing and having to loop.
- * - When using custom_read_reg32/custom_write_reg32 only perform the
- * necessary logical operations on the register value in between these
- * two calls. All other logic should be performed before the first call.
-  * - There is a bug on the R10000 chips which has a workaround. If you
- * are affected by this bug, make sure to define the symbol 'R10000_LLSC_WAR'
- * to be non-zero.  If you are using this header from within linux, you may
- * include <asm/war.h> before including this file to have this defined
- * appropriately for you.

- * Notes:
- *  1) The SPI registers are split into two blocks, one offset from the
- *     MSP_SPI_BASE by 0x00 and the other offset from the MSP_SPI_BASE by
- *     0x68.  The SPI driver definitions for the register must be aware
- *     of this.
- *  2) The block copy engine register are divided into two regions, one
- *     for the control/configuration of the engine proper and one for the
- *     values of the descriptors used in the copy process.  These have
- *     different base defines (CTRL_BASE vs DESC_BASE)
- *  3) These constants are for physical addresses which means that they
- *     work correctly with "ioremap" and friends.  This means that device
- *     drivers will need to remap these addresses using ioremap and perhaps
- *     the readw/writew macros.	 Or they could use the regptr() macro
- *     defined below, but the readw/writew calls are the correct thing.
- *  4) The UARTs have an additional status register offset from the base
- *     address.	 This register isn't used in the standard 8250 driver but
- *     may be used in other software.  Consult the hardware datasheet for
- *     offset details.
- *  5) For some unknown reason the security engine (MSP_SEC_BASE) registers
- *     start at an offset of 0x84 from the base address but the block of
- *     registers before this is reserved for the security engine.  The
- *     driver will have to be aware of this but it makes the register
- *     definitions line up better with the documentation.

-KVM/MIPS Trap & Emulate Release Notes
-=====================================
-
-(1) KVM/MIPS should support MIPS32R2 and beyond. It has been tested on the following platforms:
-    Malta Board with FPGA based 34K
-    Sigma Designs TangoX board with a 24K based 8654 SoC.
-    Malta Board with 74K @ 1GHz
-
-(2) Both Guest kernel and Guest Userspace execute in UM.
-    Guest User address space:   0x00000000 -> 0x40000000
-    Guest Kernel Unmapped:      0x40000000 -> 0x60000000
-    Guest Kernel Mapped:        0x60000000 -> 0x80000000
-
-    Guest Usermode virtual memory is limited to 1GB.
-
-(2) 16K Page Sizes: Both Host Kernel and Guest Kernel should have the same page size, currently at least 16K.
-    Note that due to cache aliasing issues, 4K page sizes are NOT supported.
-
-(3) No HugeTLB Support
-    Both the host kernel and Guest kernel should have the page size set to 16K.
-    This will be implemented in a future release.
-
-(4) KVM/MIPS does not have support for SMP Guests
-    Linux-3.7-rc2 based SMP guest hangs due to the following code sequence in the generated TLB handlers:
-	LL/TLBP/SC.  Since the TLBP instruction causes a trap the reservation gets cleared
-	when we ERET back to the guest. This causes the guest to hang in an infinite loop.
-	This will be fixed in a future release.
-
-(5) Use Host FPU
-    Currently KVM/MIPS emulates a 24K CPU without a FPU.
-    This will be fixed in a future release

+ * Code overview
+ * =============
+ *
+ * - bpf_jit_comp.h
+ *   Common definitions and utilities.
+ *
+ * - bpf_jit_comp.c
+ *   Implementation of JIT top-level logic and exported JIT API functions.
+ *   Implementation of internal operations shared by 32-bit and 64-bit code.
+ *   JMP and ALU JIT control code, register control code, shared ALU and
+ *   JMP/JMP32 JIT operations.
+ *
+ * - bpf_jit_comp32.c
+ *   Implementation of functions to JIT prologue, epilogue and a single eBPF
+ *   instruction for 32-bit MIPS CPUs. The functions use shared operations
+ *   where possible, and implement the rest for 32-bit MIPS such as ALU64
+ *   operations.
+ *
+ * - bpf_jit_comp64.c
+ *   Ditto, for 64-bit MIPS CPUs.
+ *
+ * Zero and sign extension
+ * ========================
+ * 32-bit MIPS instructions on 64-bit MIPS registers use sign extension,
+ * but the eBPF instruction set mandates zero extension. We let the verifier
+ * insert explicit zero-extensions after 32-bit ALU operations, both for
+ * 32-bit and 64-bit MIPS JITs. Conditional JMP32 operations on 64-bit MIPs
+ * are JITed with sign extensions inserted when so expected.
+ *
+ * ALU operations
+ * ==============
+ * ALU operations on 32/64-bit MIPS and ALU64 operations on 64-bit MIPS are
+ * JITed in the following steps. ALU64 operations on 32-bit MIPS are more
+ * complicated and therefore only processed by special implementations in
+ * step (3).
+ *
+ * 1) valid_alu_i:
+ *    Determine if an immediate operation can be emitted as such, or if
+ *    we must fall back to the register version.
+ *
+ * 2) rewrite_alu_i:
+ *    Convert BPF operation and immediate value to a canonical form for
+ *    JITing. In some degenerate cases this form may be a no-op.
+ *
+ * 3) emit_alu_{i,i64,r,64}:
+ *    Emit instructions for an ALU or ALU64 immediate or register operation.
+ *
+ * JMP operations
+ * ==============
+ * JMP and JMP32 operations require an JIT instruction offset table for
+ * translating the jump offset. This table is computed by dry-running the
+ * JIT without actually emitting anything. However, the computed PC-relative
+ * offset may overflow the 18-bit offset field width of the native MIPS
+ * branch instruction. In such cases, the long jump is converted into the
+ * following sequence.
+ *
+ *    <branch> !<cond> +2    Inverted PC-relative branch
+ *    nop                    Delay slot
+ *    j <offset>             Unconditional absolute long jump
+ *    nop                    Delay slot
+ *
+ * Since this converted sequence alters the offset table, all offsets must
+ * be re-calculated. This may in turn trigger new branch conversions, so
+ * the process is repeated until no further changes are made. Normally it
+ * completes in 1-2 iterations. If JIT_MAX_ITERATIONS should reached, we
+ * fall back to converting every remaining jump operation. The branch
+ * conversion is independent of how the JMP or JMP32 condition is JITed.
+ *
+ * JMP32 and JMP operations are JITed as follows.
+ *
+ * 1) setup_jmp_{i,r}:
+ *    Convert jump conditional and offset into a form that can be JITed.
+ *    This form may be a no-op, a canonical form, or an inverted PC-relative
+ *    jump if branch conversion is necessary.
+ *
+ * 2) valid_jmp_i:
+ *    Determine if an immediate operations can be emitted as such, or if
+ *    we must fall back to the register version. Applies to JMP32 for 32-bit
+ *    MIPS, and both JMP and JMP32 for 64-bit MIPS.
+ *
+ * 3) emit_jmp_{i,i64,r,r64}:
+ *    Emit instructions for an JMP or JMP32 immediate or register operation.
+ *
+ * 4) finish_jmp_{i,r}:
+ *    Emit any instructions needed to finish the jump. This includes a nop
+ *    for the delay slot if a branch was emitted, and a long absolute jump
+ *    if the branch was converted.

+ * Mapping of 64-bit eBPF registers to 32-bit native MIPS registers.
+ *
+ * 1) Native register pairs are ordered according to CPU endianness, following
+ *    the MIPS convention for passing 64-bit arguments and return values.
+ * 2) The eBPF return value, arguments and callee-saved registers are mapped
+ *    to their native MIPS equivalents.
+ * 3) Since the 32 highest bits in the eBPF FP register are always zero,
+ *    only one general-purpose register is actually needed for the mapping.
+ *    We use the fp register for this purpose, and map the highest bits to
+ *    the MIPS register r0 (zero).
+ * 4) We use the MIPS gp and at registers as internal temporary registers
+ *    for constant blinding. The gp register is callee-saved.
+ * 5) One 64-bit temporary register is mapped for use when sign-extending
+ *    immediate operands. MIPS registers t6-t9 are available to the JIT
+ *    for as temporaries when implementing complex 64-bit operations.
+ *
+ * With this scheme all eBPF registers are being mapped to native MIPS
+ * registers without having to use any stack scratch space. The direct
+ * register mapping (2) simplifies the handling of function calls.

- *
- *  STRUCTURE: msp_pci_controller
- *  _________________________________________________________________________
- *
- *  Describes the attributes of the MSP7120 PCI Host Controller
- *
- *  ELEMENTS:
- *    pci_ops	   - abstracts the hardware specific PCI configuration
- *		     accesses.
- *
- *    mem_resource - address range pciauto() uses to assign to PCI device
- *		     memory BARs.
- *
- *    mem_offset   - offset between how MSP7120 outbound PCI memory
- *		     transaction addresses appear on the PCI bus and how Linux
- *		     wants to configure memory BARs of the PCI devices.
- *		     MSP7120 does nothing funky, so just set to zero.
- *
- *    io_resource  - address range pciauto() uses to assign to PCI device
- *		     I/O BARs.
- *
- *    io_offset	   - offset between how MSP7120 outbound PCI I/O
- *		     transaction addresses appear on the PCI bus and how
- *		     Linux defaults to configure I/O BARs of the PCI devices.
- *		     MSP7120 maps outbound I/O accesses into the bottom
- *		     bottom 4K of PCI address space (and ignores OATRAN).
- *		     Since the Linux default is to configure I/O BARs to the
- *		     bottom 4K, no special offset is needed. Just set to zero.
