Standardize the style for compiler based printf format verification.

Moving the event counter into the dynamically allocated 'struc seq_file'
allows poll() support without the need to allocate its own tracking
structure.All current users are switched over to use the new counter.

Add two helpers that allow access to the seq_file's own buffer, but
hide the internal details of seq_files.This allows easier implementation of special purpose filling
functions. It also cleans up some existing functions which duplicated
the seq_file logic.Make these inline functions in seq_file.h, as suggested by Al.

Currently seq_read assumes that the offset passed to it is always the
offset it passed to user space. In the case pread this assumption is
broken and we do the wrong thing when presented with pread.To solve this I introduce an offset cache inside of struct seq_file so we
know where our logical file position is. Then in seq_read if we try to
read from another offset we reset our data structures and attempt to go to
the offset user space wanted.[akpm@linux-foundation.org: restore FMODE_PWRITE]
[pjt@google.com: seq_open needs its fmode opened up to take advantage of this]

Impact: cleanup, futureproof
nr_cpu_ids is the (badly named) runtime limit on possible CPU numbers;
ie. the variable version of NR_CPUS.With the new cpumask operators, only bits less than this are defined.
So we should use it everywhere, rather than NR_CPUS. Eventually this
will make it possible to allocate cpumasks of the minimal length at runtime.Signed-off-by: Rusty Russell

Short enough reads from /proc/irq/*/smp_affinity return -EINVAL for no
good reason.This became noticed with NR_CPUS=4096 patches, when length of printed
representation of cpumask becase 1152, but cat(1) continued to read with
1024-byte chunks. bitmap_scnprintf() in good faith fills buffer, returns
1023, check returns -EINVAL.Fix it by switching to seq_file, so handler will just fill buffer and
doesn't care about offsets, length, filling EOF and all this crap.For that add seq_bitmap(), and wrappers around it -- seq_cpumask() and
seq_nodemask().Signed-off-by: Alexey Dobriyan

Fix f_version type: should be u64 instead of long
There is a type inconsistency between struct inode i_version and struct file
f_version.fs.h:
struct inode
u64 i_version;and
struct file
unsigned long f_version;Users do:
fs/ext3/dir.c:
if (filp->f_version != inode->i_version) {
So why isn't f_version a u64 ? It becomes a problem if versions gets
higher than 2^32 and we are on an architecture where longs are 32 bits.This patch changes the f_version type to u64, and updates the users accordingly.
It applies to 2.6.23-rc2-mm2.

Many places in kernel use seq_file API to iterate over a regular list_head.
The code for such iteration is identical in all the places, so it's worth
introducing a common helpers.This makes code about 300 lines smaller:
The first version of this patch made the helper functions static inline
in the seq_file.h header. This patch moves them to the fs/seq_file.c as
Andrew proposed. The vmlinux .text section sizes are as follows:2.6.22-rc1-mm1: 0x001794d5
with the previous version: 0x00179505

the possible options to make the files modified by the patch compile plus
drivers I have on the test node.This patch:

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
