[PATCH v2 2/4] hpet: pass physical address, not entire hpet_data, to hpet_is_known()
No functional change; hpet_is_known() only needs the physical address, so supplying that instead of the whole struct hpet_data makes the callers a little simpler.

[PATCH v2 0/4] hpet: convert from ACPI to PNP driver
The HPET driver parses ACPI _CRS data manually, but PNPACPI already does that, and it does a more complete job, so we can simplify the HPET driver quite a bit by taking advantage of that. Clemens, if you like these, will you take care of merging them, or do I need to shepherd them through some other path? Chan... 18 Mar 2010 14:20

[PATCH v2 3/4] hpet: clean up io mapping when hpet_alloc() fails
When hpet_alloc() fails, we should iounmap() the timer so we don't leak the mapping.

should we use $(__USER_DS) or $(__KERNEL_DS) when entering interrupt handlers?
in handling an interrupt, kernel first saves all the register contents , in the SAVE_ALL macro, in the last part of this macro,� it adjusts the data segment selectors for kernel mode. in kernel 2.4, the __KERNEL_DS segment is loaded into %ds and %es, at line 98 of: http://lxr.linux.no/#linux-old+v2.4.31/arch/i... 18 Mar 2010 14:20
