This moves the private HPET structures into the C module, simplifies some helper functions and fixes most coding style issues (biggest chunk was improper switch-case indention). No functional changes. Signed-off-by: NJan Kiszka <jan.kiszka@siemens.com> Reviewed-by: NJuan Quintela <quintela@redhat.com> Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>

This patch addresses the problems found by Andriy Gapon: - The code was incorrectly overwriting the high order 32 bits of the timer and hpet config registers. This didn't show up in testing because linux and windows use hpet in legacy mode, where the high order 32 bits (advertising available interrupts) of the timer config register are ignored, and the high order 32 bits of the hpet config register are reserved and unused. - The mask for level-triggered interrupts was off by a bit. (hpet doesn't currently support level-triggered interrupts). In addition, I removed some unused #defines, and corrected the ioapic interrupt values advertised. I'd set this up early in hpet development and never went back to correct it, and no bugs resulted since linux and windows use hpet in legacy mode where available interrupts are ignored.

I discovered a bug in the hpet code that caused Windows to boot without hpet. The config mask I was using was preventing the guest from placing the hpet into 32 bit mode. (Beth Kon) git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6357 c046a42c-6fe2-441c-8c8c-71466251a162

This patch adds HPET emulation. It can be disabled with -disable-hpet. An hpet provides a more finely granular clocksource than otherwise available on PC. This means that latency-dependent applications (e.g. multimedia) will generally be smoother when using the HPET.
