2011-03-09microblaze: Fix /dev/zero corruption from __clear_user()Steven J. Magnani
A userland read of more than PAGE_SIZE bytes from /dev/zero results in (a) not all of the bytes returned being zero, and (b) memory corruption due to zeroing of bytes beyond the user buffer. This is caused by improper constraints on the assembly __clear_user function. The constrints don't indicate to the compiler that the pointer argument is modified. Since the function is inline, this results in double-incrementing of the pointer when __clear_user() is invoked through a multi-page read() of /dev/zero. Signed-off-by: Steven J.

2011-03-09ARM: 6777/1: gic: Add hooks for architecture specific extensionsSantosh Shilimkar
Few architectures combine the GIC with an external interrupt controller. On such systems it may be necessary to update both the GIC registers and the external controller's registers to control IRQ behavior. This can be addressed in couple of possible methods. 1. Export common GIC routines along with 'struct irq_chip gic_chip' and allow architectures to have custom function by override. 2. Provide architecture specific function pointer hooks within GIC library and leave platforms to add the necessary code as part of these hooks. First one might be non-intrusive but have few shortcomings like arch needs to have there own custom gic library. Locks used should be common since it caters to same IRQs etc. Maintenance point of view also it leads to multiple file fixes. The second probably is cleaner and portable. It ensures that all the common GIC infrastructure is not touched and also provides archs to address their specific issue.
