2012-10-06cross-arch: don't corrupt personality flags upon exec()Jiri Kosina
Historically, the top three bytes of personality have been used for things such as ADDR_NO_RANDOMIZE, which made sense only for specific architectures. We now however have a flag there that is general no matter the architecture (UNAME26); generally we have to be careful to preserve the personality flags across exec(). This patch tries to fix all architectures that forcefully overwrite personality flags during exec() (ppc32 and s390 have been fixed recently by commits f9783ec862ea ("[S390] Do not clobber personality flags on exec") and 59e4c3a2fe9c ("powerpc/32: Don't clobber personality flags on exec") in a similar way already).

2012-05-24sh: se722: Move FPGA IRQs to irqdomain and generic irq chip.Paul Mundt
This implements a total rewrite of the rather buggy SE7722 FPGA IRQ code, utilizing a linear irq domain as well as the generic irq chip type. While the interaction between the two APIs is a bit clunky (ie, revmap lookup for gc irq_base), they work well enough together that it's easy enough to work with going forward. While we're at it, deal with irq_mask_ack/unmask of the chained IRQ in the demux handler to prevent smc91x screaming about spurious interrupts. There's also some more improvement that can be made to the irqdomain code to create backing irqdescs for the entire linear range in one bang instead of iterating over the number of hwirqs and doing it irq-at-a-time. This is easily dealt with at a later point, though. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2012-05-21sh: Kill off machvec IRQ hinting.Paul Mundt
Everything is using sparseirq these days, so we have no need to arbitrarily size nr_irqs ahead of time. The legacy IRQ pre-allocation likewise has no meaning for us, so that's killed off too. We now depend on nr_irqs expansion by the generic hardirq layer instead.
