debugfs: add missing #ifdef HAS_IOMEM

2012-01-04T00:45:16+00:00

"debugfs: add tools to printk 32-bit registers" adds new functions which rely
on IOMEM functionality which is not present on all architectures and therefore
result in compile errors:

fs/debugfs/file.c: In function 'debugfs_print_regs32':
fs/debugfs/file.c:561:7: error: implicit declaration of function 'readl' [-Werror=implicit-function-declaration]

Add an #ifdef CONFIG_HAS_IOMEM to fix this

debugfs: remove unneeded cast in debugfs_print_regs32()

2011-11-27T04:12:47+00:00

The cast here causes a Sparse warning:
fs/debugfs/file.c:561:42: warning: cast removes address space of expression
fs/debugfs/file.c:561:42: warning: incorrect type in argument 1 (different address spaces)
fs/debugfs/file.c:561:42:    expected void const volatile [noderef] *addr
fs/debugfs/file.c:561:42:    got void *

It's redundant to cast it to a (void *) anyway when it is already a
(void __iomem *).

debugfs: bugfix: include in file.c

2011-11-22T18:20:05+00:00

The regs32 machinery uses readl. I forgot the mandatory include
and the code was not compiling on all archs.

debugfs: add tools to printk 32-bit registers

2011-11-18T18:31:22+00:00

Some debugfs file I deal with are mostly blocks of registers,
i.e. lines of the form " = 0x". Some files are only
registers, some include registers blocks among other material.  This
patch introduces data structures and functions to deal with both
cases.  I expect more users of this over time.

debugfs: Fix a comment mistake

The file is fs/debugfs/inode.c but the comment says it is file.c.
This patch can fix this little mistake.
