- File is moved to arch-v32/mach-fs/hwregs/timer_defs.h
|
|
- Change spin_lock + local_irq_save into spin_lock_irqsave
- Change spin_unlock + local_irq_restore into spin_unlock_irqrestore
- Return ENOTTY if ioctl is not recognized as a cris ioctl.
- Make init functions static.
|

Changes as suggested by Andrew Morton, plus general cleanup to
ease later consolidation of driver into machine common driver.
- Correct parameter type of gpio_write to const char __user *
- Remove volatile from the arrays of machine dependent registers, use
readl and writel to access them instead.
- Remove useless casts of void.
- Use spin_lock_irqsave for locking.
- Break gpio_write into smaller sub-functions.
- Remove useless breaks after returns.
- Don't perform any change in IO_CFG_WRITE_MODE if values are invalid.
(previously values were set and then set to zero)
- Change cast for copy_to_user to (void __user *)
- Make file_operations gpio_fops static and const.
- Make setget_output static. (However, it's still inline since the CRIS
architecture is still not SMP, which makes the function small enough
to inline)

This patch contain the core infrastructure of enhanced partition
statistics. It adds to struct hd_struct the same stats data as struct
gendisk and define basics function to manipulate them.

Rearrange fields in cache order and initialize some fields that
we didn't previously init. Remove init of ->completion_data, it's
part of a union with ->hash. Luckily clearing the rb node is the same
as setting it to null!

Clean up issues noticed by Andrew Morton:
- Use a combined struct for allocating the mtd_info and nand_chip structs
instead of using anonymous memory as the example in
Documentation/DocBook/mtdnand.tmpl
- Use kzalloc instead of using kmalloc/memset(0)
- Make crisv32_device_ready static.
|
|
- Change parameters of gpio_write (const char * buf -> const char __user *buf)
- Don't initialize static variables to zero.
- Remove useless casts from void.
- Change name of interrupt routine (gpio_pa_interrupt -> gpio_interrupt)
- Use kzmalloc instead of allocating memory and zeroing it manually.
- Correct casts for copy_to_user and copy_from_user to (void __user *)
- Make file_operations gpio_fops static.
- Make ioif_watcher static, not used outside this file.

- Add ifdef around macros to read and write hardware registers
- Add parens around REG_READ expression to avoid possible precedence errors.
- Remove useless CVS id tag.

This file is machine dependent, and needs to be in

Deallocation was not possible before, but is now.

Also, fix a typo.

- A couple of fields have changed name:
reg_eth_rw_ga_lo.table -> tbl
reg_eth_rw_ga_hi.table -> tbl
reg_eth_rw_gen_ctrl.flow_ctrl_dis -> flow_ctrl
- Add some new register fields.
reg_eth_rw_gen_ctrl.gtxclk_out
reg_eth_rw_gen_ctrl.phyrst_n
reg_eth_rw_tr_ctrl.carrier_ext
- max_size in reg_eth_rw_rec_ctrl had the wrong size.
- Registers reg_eth_rw_mgm_ctrl and reg_eth_r_stat was reworked completely.

The old name "r" would quite often produce warnings when other
variables with the same name was shadowed. Rename it __x to
make it more unlikely to happen.

Using kmalloc instead of vmalloc solves the stability problems
experienced by some 100 LX products.
