Fix wrong netmos 9855 serial port configuration.
On loading only one serial port was present and it wasn't working. After
looking in the data sheet I realized that the base address was wrong. For

Turn on INTR/QUIT/SUSP echoing in the N_TTY line discipline (e.g. ctrl-C
will appear as "^C" if stty echoctl is set and ctrl-C is set as INTR).Linux seems to be the only unix-like OS (recently I've verified this on
Solaris, BSD, and Mac OS X) that does *not* behave this way, and I really
miss this as a good visual confirmation of the interrupt of a program in
the console or xterm. I remember this fondly from many Unixs I've used
over the years as well. Bringing this to Linux also seems like a good way
to make it yet more compliant with standard unix-like behavior.[akpm@linux-foundation.org: coding-style fixes]

This adds support to allow asm/ptrace.h to define two new macros,
arch_ptrace_stop_needed and arch_ptrace_stop. These control special
machine-specific actions to be done before a ptrace stop. The new code
compiles away to nothing when the new macros are not defined. This is the
case on all machines to begin with.On ia64, these macros will be defined to solve the long-standing issue of
ptrace vs register backing store.Signed-off-by: Roland McGrath

We restarted scan of sb->s_inodes list whenever we had to drop inode_lock
in add_dquot_ref(). This leads to overall quadratic running time and thus
add_dquot_ref() can take several minutes when called on a life filesystem.
We fix the problem by using the fact that inode cannot be removed from
s_inodes list while we hold a reference to it and thus we can safely
restart the scan if we don't drop the reference. Here we use the fact that
inodes freshly added to s_inodes list are already guaranteed to have quotas
properly initialized and the ordering of inodes on s_inodes list does not
change so we cannot skip any inode.Thanks goes to Nick for analyzing the problem and
testing the fix.[akpm@linux-foundation.org: iput(NULL) is legal]

When resolving symbol names from addresses with aliased symbol names,
kallsyms_lookup always returns the first symbol, even if it is a weak
symbol.This patch changes this by sorting the symbols with the weak symbols last
before feeding them to the kernel. This way the kernel runtime isn't
changed at all, only the kallsyms build system is changed.Another side effect is that the symbols get sorted by address, too. So,
even if future binutils version have some bug in "nm" that makes it fail to
correctly sort symbols by address, the kernel won't be affected by this.Mathieu says:
I created a module in LTTng that uses kallsyms to get the symbol
corresponding to a specific system call address. Unfortunately, all the
unimplemented syscalls were all referring to the (same) weak symbol
identifying an unrelated system call rather that sys_ni (or whatever
non-weak symbol would be expected). Kallsyms was dumbly returning the first
symbol that matched.This patch makes sure kallsyms returns the non-weak symbol when there is
one, which seems to be the expected result.[akpm@linux-foundation.org: coding-style fixes]

The inotify debugging code is supposed to verify that the
DCACHE_INOTIFY_PARENT_WATCHED scalability optimisation does not result in
notifications getting lost nor extra needless locking generated.Unfortunately there are also some races in the debugging code. And it isn't
very good at finding problems anyway. So remove it for now.Signed-off-by: Nick Piggin

There is a race between setting an inode's children's "parent watched" flag
when placing the first watch on a parent, and instantiating new children of
that parent: a child could miss having its flags set by
set_dentry_child_flags, but then inotify_d_instantiate might still see
!inotify_inode_watched.The solution is to set_dentry_child_flags after adding the watch. Locking is
taken care of, because both set_dentry_child_flags and inotify_d_instantiate
hold dcache_lock and child->d_locks.Signed-off-by: Nick Piggin

The rcu_assign_pointer() primitive currently unconditionally executes a
memory barrier, even when a NULL pointer is being assigned. This has lead
some to avoid using rcu_assign_pointer() for NULL pointers, which loses the
self-documenting advantages of rcu_assign_pointer() This patch uses
__builtin_const_p() to omit needless memory barriers for NULL-pointer
assignments at compile time with no runtime penalty, as discussed in the
following thread:http://www.mail-archive.com/netdev@vger.kernel.org/msg54852.html

The declaration and implementation of __const_udelay use different

arch/sh/lib/delay.c:22:inline void __const_udelay(unsigned long xloops)include/asm-m32r/delay.h:15:extern void __const_udelay(unsigned long usecs);
arch/m32r/lib/delay.c:58:void __const_udelay(unsigned long xloops)include/asm-x86/delay.h:16:extern void __const_udelay(unsigned long usecs);
arch/x86/lib/delay_32.c:82:inline void __const_udelay(unsigned long xloops)
arch/x86/lib/delay_64.c:46:inline void __const_udelay(unsigned long xloops)The units of the parameter isn't usecs, so that name is definitely
wrong. It's also not exactly loops, so I suppose xloops is an OK
name.This patch changes these names from usecs to xloops.

NR_OPEN (historically set to 1024*1024) actually forbids processes to open
more than 1024*1024 handles.Unfortunatly some production servers hit the not so 'ridiculously high
value' of 1024*1024 file descriptors per process.Changing NR_OPEN is not considered safe because of vmalloc space potential
exhaust.This patch introduces a new sysctl (/proc/sys/fs/nr_open) wich defaults to
1024*1024, so that admins can decide to change this limit if their workload
needs it.[akpm@linux-foundation.org: export it for sparc64]

Currently, no notification event has been sent when inode's link count
changed. This is inconvenient for the application in some cases:Suppose you have the following directory structure
foo/test
bar/and you watch test. If someone does "mv foo/test bar/", you get event
IN_MOVE_SELF and you know something has happened with the file "test".
However if someone does "ln foo/test bar/test" and "rm foo/test" you get no
inotify event for the file "test" (only directories "foo" and "bar" receive
events).Furthermore it could be argued that link count belongs to file's metadata and
thus IN_ATTRIB should be sent when it changes.The following patch implements sending of IN_ATTRIB inotify events when link
count of the inode changes, i.e., when a hardlink to the inode is created or
when it is removed. This event is sent in addition to all the events sent so
far. In particular, when a last link to a file is removed, IN_ATTRIB event is
sent in addition to IN_DELETE_SELF event.Signed-off-by: Jan Kara
