2008-03-22[SPARC64]: Remove most limitations to kernel image size.David S. Miller4-158/+93
Currently kernel images are limited to 8MB in size, and this causes problems especially when enabling features that take up a lot of kernel image space such as lockdep. The code now will align the kernel image size up to 4MB and map that many locked TLB entries. So, the only practical limitation is the number of available locked TLB entries which is 16 on Cheetah and 64 on pre-Cheetah sparc64 cpus. Niagara cpus don't actually have hw locked TLB entry support. Rather, the hypervisor transparently provides support for "locked" TLB entries since it runs with physical addressing and does the initial TLB miss processing. Fully utilizing this change requires some help from SILO, a patch for which will be submitted to the maintainer. Essentially, SILO will only currently map up to 8MB for the kernel image and that needs to be increased. Note that neither this patch nor the SILO bits will help with network booting. The openfirmware code will only map up to a certain amount of kernel image during a network boot and there isn't much we can to about that other than to implemented a layered network booting facility. Solaris has this, and calls it "wanboot" and we may implement something similar at some point. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-03-05Kprobes: indicate kretprobe support in KconfigAnanth N Mavinakayanahalli1-0/+1
Add CONFIG_HAVE_KRETPROBES to the arch/<arch>/Kconfig file for relevant architectures with kprobes support. This facilitates easy handling of in-kernel modules (like samples/kprobes/kretprobe_example.c) that depend on kretprobes being present in the kernel. Thanks to Sam Ravnborg for helping make the patch more lean. Per Mathieu's suggestion, added CONFIG_KRETPROBES and fixed up dependencies.

2008-02-29[SPARC64]: Adjust kernel PC validation test in fault handler.David S. Miller1-1/+1

2008-02-27[SPARC64]: Loosen checks in exception table handling.David S. Miller1-10/+2
Some parts of the kernel now do things like do *_user() accesses while set_fs(KERNEL_DS) that fault on purpose. See, for example, the code added by changeset a0c1e9073ef7428a14309cba010633a6cd6719ea ("futex: runtime enable pi and robust functionality"). That trips up the ASI sanity checking we make in do_kernel_fault(). Just remove it for now. Maybe we can add it back later with an added conditional which looks at the current get_fs() value.

2008-02-19[SPARC]: Kill 'prom_palette'.David S. Miller4-22/+0
The idea of this thing is we could save/restore the firmware's palette when breaking in and out of the firmware prompt. Only one driver implemented this (atyfb) and it's value is questionable.

2008-02-15Embed a struct path into struct nameidata instead of nd->{dentry,mnt}Jan Blunck1-4/+4
This is the central patch of a cleanup series. In most cases there is no good reason why someone would want to use a dentry for itself. This series reflects that fact and embeds a struct path into nameidata. Together with the other patches of this series - it enforced the correct order of getting/releasing the reference count on <dentry,vfsmount> pairs - it prepares the VFS for stacking support since it is essential to have a struct path in every place where the stack can be traversed - it reduces the overall code size: without patch series: text data bss dec hex filename 5321639 858418 715768 6895825 6938d1 vmlinux with patch series: text data bss dec hex filename 5320026 858418 715768 6894212 693284 vmlinux This patch: Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.
