[PATCH] I2C: hwmon: Rename register parameters

"register" is a reserved keyword so using it as a parameter name
can confuse some compilers, most notably ICC.

The patch below just renames all occurences to reg which fits the actual
function declarations.

[PATCH] __GENERIC_PER_CPU changes

Now CONFIG_DEBUG_INITDATA is in, initial percpu data
[__per_cpu_start,__per_cpu_end] can be declared as a redzone, and invalid
accesses after boot can be detected, at least for i386.

We can let non possible cpus percpu data point to this 'redzone' instead of
NULL .

NULL was not a good choice because part of [0..32768] memory may be
readable and invalid accesses may happen unnoticed.

If CONFIG_DEBUG_INITDATA is not defined, each non possible cpu points to
the initial percpu data (__per_cpu_offset[cpu] == 0), thus invalid accesses
wont be detected/crash.

sharing.

When we stop allocating percpu memory for not-possible CPUs we must not touch
the percpu data for not-possible CPUs at all.  The correct way of doing this

few instances of this bug, if any.  But the patch converts lots of open-coded
test to use the preferred helper macros.

13 years ago[PATCH] get_empty_filp tweaks, inline epoll_init_file()
Benjamin LaHaise [Thu, 23 Mar 2006 11:01:03 +0000]
[PATCH] get_empty_filp tweaks, inline epoll_init_file()

Eliminate a handful of cache references by keeping current in a register
instead of reloading (helps x86) and avoiding the overhead of a function
call.  Inlining eventpoll_init_file() saves 24 bytes.  Also reorder file
initialization to make writes occur more sequentially.

[PATCH] atomic: add_unless cmpxchg optimise

Without branch hints, the very unlikely chance of the loop repeating due to
cmpxchg failure is unrolled with gcc-4 that I have tested.

Improve this for architectures with a native cas/cmpxchg.  llsc archs
should try to implement this natively.

Andrew Morton [Thu, 23 Mar 2006 11:00:57 +0000]
[PATCH] pause_on_oops command line option

Attempt to fix the problem wherein people's oops reports scroll off the screen
due to repeated oopsing or to oopses on other CPUs.

If this happens the user can reboot with the `pause_on_oops=<seconds>' option.
It will allow the first oopsing CPU to print an oops record just a single
time.  Second oopsing attempts, or oopses on other CPUs will cause those CPUs
to enter a tight loop until the specified number of seconds have elapsed.

The patch implements the infrastructure generically in the expectation that
architectures other than x86 will find it useful.

[PATCH] Fix oops in invalidate_dquots()

When quota is being turned off we assumed that all the references to dquots
were already dropped.  That need not be true as inodes being deleted are
not on superblock's inodes list and hence we need not reach it when
removing quota references from inodes.  So invalidate_dquots() has to wait
for all the users of dquots (as quota is already marked as turned off, no
new references can be acquired and so this is bound to happen rather
early).  When we do this, we can also remove the iprune_sem locking as it
was protecting us against exactly the same problem when freeing inodes
icache memory.

13 years ago[PATCH] Shrinks sizeof(files_struct) and better layout
Eric Dumazet [Thu, 23 Mar 2006 11:00:12 +0000]
[PATCH] Shrinks sizeof(files_struct) and better layout

1) Reduce the size of (struct fdtable) to exactly 64 bytes on 32bits
   platforms, lowering kmalloc() allocated space by 50%.

2) Reduce the size of (files_struct), using a special 32 bits (or
   64bits) embedded_fd_set, instead of a 1024 bits fd_set for the
   close_on_exec_init and open_fds_init fields.  This save some ram (248
   bytes per task) as most tasks dont open more than 32 files.  D-Cache
   footprint for such tasks is also reduced to the minimum.

3) Reduce size of allocated fdset.  Currently two full pages are
   allocated, that is 32768 bits on x86 for example, and way too much.  The
   minimum is now L1_CACHE_BYTES.

UP and SMP should benefit from this patch, because most tasks will touch
only one cache line when open()/close() stdin/stdout/stderr (0/1/2),
(next_fd, close_on_exec_init, open_fds_init, fd_array[0 ..  2] being in the
same cache line)

13 years ago[PATCH] ext3_readdir: use generic readahead
Andrew Morton [Thu, 23 Mar 2006 11:00:11 +0000]
[PATCH] ext3_readdir: use generic readahead

Linus points out that ext3_readdir's readahead only cuts in when
ext3_readdir() is operating at the very start of the directory.  So for large
directories we end up performing no readahead at all and we suck.

So take it all out and use the core VM's page_cache_readahead().  This means
that ext3 directory reads will use all of readahead's dynamic sizing goop.

Note that we're using the directory's filp->f_ra to hold the readahead state,
but readahead is actually being performed against the underlying blockdev's
address_space.  Fortunately the readahead code is all set up to handle this.

Tested with printk.  It works.  I was struggling to find a real workload which
actually cared.

(The patch also exports page_cache_readahead() to GPL modules)
