2008-03-25[SPARC64]: Fix sparse warnings in arch/sparc64/kernel/{cpu,setup}.cDavid S. Miller
We create a local header file entry.h, under arch/sparc64/kernel/, that we can use to declare routines either defined in assembler or only invoked from assembler. As well as other data objects which are private to the inner sparc64 kernel arch code. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-03-24[SPARC64]: Make save_stack_trace() more efficient.David S. Miller
Doing a 'flushw' every stack trace capture creates so much overhead that it makes lockdep next to unusable. We only care about the frame pointer chain and the function caller program counters, so flush those by hand to the stack frame. This is significantly more efficient than a 'flushw' because: 1) We only save 16 bytes per active register window to the stack. 2) This doesn't push the entire register window context of the current call chain out of the cpu, forcing register window fill traps as we return back down. Note that we can't use 'restore' and 'save' instructions to move around the register windows because that wouldn't work on Niagara processors. They optimize 'save' into a new register window by simply clearing out the registers instead of pulling them in from the on-chip register window backing store. Based upon a report by Tom Callaway.

2008-03-21[SPARC64]: Remove most limitations to kernel image size.David S. Miller
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>

2008-02-26[SPARC64]: Loosen checks in exception table handling.David S. Miller
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.

2008-02-23uml: fix FP register corruptionJeff Dike
Commit ee3d9bd4de1ed93d2a7ee41c331ed30a1c7b8acd ("uml: simplify SIGSEGV handling"), while greatly simplifying the kernel SIGSEGV handler that runs in the process address space, introduced a bug which corrupts FP state in the process. Previously, the SIGSEGV handler called the sigreturn system call by hand - it couldn't return through the restorer provided to it because that could try to call the libc restorer which likely wouldn't exist in the process address space. So, it blocked off some signals, including SIGUSR1, on entry to the SIGSEGV handler, queued a SIGUSR1 to itself, and invoked sigreturn. The SIGUSR1 was delivered, and was visible to the UML kernel after sigreturn finished. The commit eliminated the signal masking and the call to sigreturn. The handler simply hits itself with a SIGTRAP to let the UML kernel know that it is finished. UML then restores the process registers, which effectively longjmps the process out of the signal handler, skipping sigreturn's restoring of register state and the signal mask. The bug is that the host apparently sets used_fp to 0 when it saves the process FP state in the sigcontext on the process signal stack. Thus, when the process is longjmped out of the handler, its FP state is corrupt because it wasn't saved on the context switch to the UML kernel. This manifested itself as sleep hanging. For some reason, sleep uses floating point in order to calculate the sleep interval. When a page fault corrupts its FP state, it is faked into essentially sleeping forever. This patch saves the FP state before entering the SIGSEGV handler and restores it afterwards.

2008-02-22Mark CC_STACKPROTECTOR as being BROKENLinus Torvalds
It's always been broken, but recent fixes actually made it do something, and now the brokenness shows up as the resulting kernel simply not working at all. So it used to be that you could enable this config option, and it just didn't do anything. Now we'd better stop people from enabling it by mistake, since it _does_ do something, but does it so badly as to be unusable. Code to actually make it work is pending, but incomplete and won't be merged into 2.6.25 in any case.
