The brd driver has never supported the ramdisk_blocksize kernel
parameter that was in the rd driver it replaced, so remove
mention of this parameter from comments and Documentation.

Commit 9db5579b ("rewrite rd") replaced rd with brd, keeping
a brd_blocksize variable in struct brd_device but never using it.

Commit a2cba291 ("brd: get rid of unused members from struct
brd_device") removed the unused variable.

Commit f5abc8e7 ("Documentation/blockdev/ramdisk.txt: updates")
removed mentions of ramdisk_blocksize from that file.

Some documented structures in the kernel use DECLARE_BITMAP to create
arrays of unsigned longs to store information using the bitmap functions.
These have to be replaced with a parsable version for kernel-doc.

For example a simple input like

    /**
     * struct something - some test
     * @members: active members
     */
    struct something {
    	DECLARE_BITMAP(members, MAX_MEMBERS);
    };

resulted in parsing warnings like

    warning: No description found for parameter 'MAX_MEMBERS)'
    warning: Excess struct/union/enum/typedef member 'members' description in 'something'

Some enumerations in the kernel headers use #ifdef to reduce their size
based on the the configuration. These lines have to be stripped to avoid
parsing problems.

For example a simple input like

    /**
     * enum flags - test flags
     * @flag1: first flag
     * @flag2: second flag
     */
    enum flags {
    	flag1 = BIT(0),
    #ifdef SECOND_FLAG
    	flag2 = BIT(1),
    #endif
    };

resulted in parsing warnings like

    warning: Enum value '#ifdef SECOND_FLAG;flag2 = BIT(1)' not described in enum 'flags'
    warning: Enum value '#endif;' not described in enum 'flags'
Signed-off-by: Conchúr Navid <conchur@web.de>
Signed-off-by: Jonathan Corbet <corbet@lwn.net>

The regex to strip single line #define's in enumerations depends on the
fact that the defines are still stored on separate lines. But the
surrounding code already removed newlines and replaced them with
semicolons.

For example a simple input like

    /**
     * enum flags - test flags
     * @flag1: first flag
     * @flag2: second flag
     * @flag3: third flag
     * @flag4: fourth flag
     */
    enum flags {
    	flag1 = BIT(0),
    	flag2 = BIT(1),
    #define flags_small (flag1 | flag2)
    	flag3 = BIT(2),
    	flag4 = BIT(3),
    #define flags_big (flag2 | flag3)
    };

resulted in parsing warnings like

    warning: Enum value '#define flags_small (flag1 | flag2);flag3 = BIT(2)' not described in enum 'flags'

  ARC: use ASL assembler mnemonic
  ARC: [arcompact] Handle bus error from userspace as Interrupt not exception
  ARC: remove extraneous header include
  ARCv2: lib: memcpy: use local symbols

cpu_relax() on ARC has been barrier only for SMP (and no-op for UP). Per
recent discussions, it is safer to make it a compiler barrier
unconditionally.

Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

Bus errors from userspace on ARCompact based cores are handled by core
as a high priority L2 interrupt but current code treated it as interrupt
Handling an interrupt like exception is certainly not going to go unnoticed.
(and it worked so far as we never saw a Bus error from userspace until
IPPK guys tested a DDR controller with ECC error detection etc hence
needed to explicitly trigger/handle such errors)

 - So move mem_service exception handler from common code into ARCv2 code.
 - In ARCompact code, define  mem_service as L2 interrupt handler which
   just drops down to pure kernel mode and goes of to enqueue SIGBUS
