[ARM] Add thread_notify infrastructure 2006-06-22T09:24:18+00:00 Russell King rmk@dyn-67.arm.linux.org.uk 2006-06-21T12:31:52+00:00 d6551e884cf66de072b81f8b6d23259462c40baf 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.)

[ARM] 3117/1: nwfpe kernel memory info leak 2005-11-07T21:12:07+00:00 Lennert Buytenhek buytenh@wantstofly.org 2005-11-07T21:12:07+00:00 06c03cac9487555478c7d80065ebf7818bf6fd06 Patch from Lennert Buytenhek The routine that nwfpe uses for converting floats/doubles to extended precision fails to zero two bytes of kernel stack. This is not immediately obvious, as the floatx80 structure has 16 bits of implicit padding (by design.) These two bytes are copied to userspace when an stfe is emulated, causing a possible info leak.
