2006-06-22[ARM] Add thread_notify infrastructureRussell King
Some machine classes need to allow VFP support to be built into the kernel, but still allow the kernel to run even though VFP isn't present. Unfortunately, the kernel hard-codes VFP instructions into the thread switch, which prevents this being run-time selectable. Solve this by introducing a notifier which things such as VFP can hook into to be informed of events which affect the VFP subsystem (eg, creation and destruction of threads, switches between threads.)

2005-08-03[PATCH] ARM: 2837/2: Re: ARM: Make NWFPE preempt safeRichard Purdie
Patch from Richard Purdie NWFPE used global variables which meant it wasn't safe for use with preemptive kernels. This patch removes them and communicates the information between functions in a preempt safe manner. Generation of some exceptions was broken and this has also been corrected. Tests with glibc's maths test suite show no change in the results before/after this patch. Signed-off-by: Richard Purdie <rpurdie@rpsys.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-07-17[PATCH] ARM: Remove global nwfpe register variableRussell King
Recent changes to nwfpe broke the build with some gcc versions: In file included from arch/arm/nwfpe/softfloat.c:33: arch/arm/nwfpe/fpa11.h:32: global register variable follows a function definition make[1]: *** [arch/arm/nwfpe/softfloat.o] Error 1 Since we now ensure that the kernel stack is empty when returning to user space, we can now access the userspace registers with reference to the kernel stack using current_thread_info(), rather than remembering the stack pointer at the time nwfpe was called.

Changing CONFIG_LOCALVERSION rebuilds too much, for no appearent reason. Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

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!
