Linus Torvalds a9a08845e9 vfs: do bulk POLL* -> EPOLL* replacement 
This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:

    for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
        L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
        for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
    done

with de-mangling cleanups yet to come.

NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do.  But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.

The next patch from Al will sort out the final differences, and we
should be all done.

* AB8500 register access
* ======================
*
* read:
* # echo BANK > <debugfs>/ab8500/register-bank
* # echo ADDR > <debugfs>/ab8500/register-address
* # cat <debugfs>/ab8500/register-value
*
* write:
* # echo BANK > <debugfs>/ab8500/register-bank
* # echo ADDR > <debugfs>/ab8500/register-address
* # echo VALUE > <debugfs>/ab8500/register-value
*
* read all registers from a bank:
* # echo BANK > <debugfs>/ab8500/register-bank
* # cat <debugfs>/ab8500/all-bank-register
*
* BANK target AB8500 register bank
* ADDR target AB8500 register address
* VALUE decimal or 0x-prefixed hexadecimal
*
*
* User Space notification on AB8500 IRQ
* =====================================
*
* Allows user space entity to be notified when target AB8500 IRQ occurs.
* When subscribed, a sysfs entry is created in ab8500.i2c platform device.
* One can pool this file to get target IRQ occurence information.
*
* subscribe to an AB8500 IRQ:
* # echo IRQ > <debugfs>/ab8500/irq-subscribe
*
* unsubscribe from an AB8500 IRQ:
* # echo IRQ > <debugfs>/ab8500/irq-unsubscribe
*
*
* AB8500 register formated read/write access
* ==========================================
*
* Read: read data, data>>SHIFT, data&=MASK, output data
* [0xABCDEF98] shift=12 mask=0xFFF => 0x00000CDE
* Write: read data, data &= ~(MASK<<SHIFT), data |= (VALUE<<SHIFT), write data
* [0xABCDEF98] shift=12 mask=0xFFF value=0x123 => [0xAB123F98]
*
* Usage:
* # echo "CMD [OPTIONS] BANK ADRESS [VALUE]" > $debugfs/ab8500/hwreg
*
* CMD read read access
* write write access
*
* BANK target reg bank
* ADDRESS target reg address
* VALUE (write) value to be updated
*
* OPTIONS
* -d|-dec (read) output in decimal
* -h|-hexa (read) output in 0x-hexa (default)
* -l|-w|-b 32bit (default), 16bit or 8bit reg access
* -m|-mask MASK 0x-hexa mask (default 0xFFFFFFFF)
* -s|-shift SHIFT bit shift value (read:left, write:right)
* -o|-offset OFFSET address offset to add to ADDRESS value
*
* Warning: bit shift operation is applied to bit-mask.
* Warning: bit shift direction depends on read or right command.
