Link time manipulation of kernel symbols like read/write
Hi folks, Is it possible to wrap module entry points like open/close during the module compilation? By wrapping, I mean interposing using linker --wrap option. This is very much possible in user space and is commonly used to interpose library functions. E.g. void * __wrap_malloc (int c) { printf ("mal... 9 May 2010 12:08

[PATCH 3/3] [RFC] power/ds2760_battery: use factor of 50 for rated_capacity
In the ds2760 driver, the currently used factor of 10 to store the rated battery capacity internally is not sufficient for batteries > 2.55 Ah, as the 8-bit register will overflow. Change the factor to 20 to broaden that range. Note that due to RATED_CAPACITY_FACTOR, the internal interface won't change, neither f... 7 May 2010 14:30

[PATCH 2/8] x86/mrst/pci: return 0 for non-present pci bars
Moorestown PCI code has special handling of devices with fixed BARs. In case of BAR sizing writes, we need to update the fake PCI MMCFG space with real size decode value. When a BAR is not present, we need to return 0 instead of ~0. ~0 will be treated as device error per bugzilla 12006. Signed-off-by: Jacob Pa... 7 May 2010 14:30

[PATCH 1/8] x86: avoid check hlt if no timer interrupts
From: Jacob Pan <jacob.jun.pan(a)intel.com> check hlt requires external timer interrupt to wake up the cpu. for platforms equipped with only per cpu timers, we don't have external interrupts during check hlt. this patch checks such condition to avoid kernel hang at hlt. it also saves boot time in that hlt four tim... 7 May 2010 14:30

[PATCH 5/8] x86/apbt: support more timer configurations on mrst
From: Jacob Pan <jacob.jun.pan(a)intel.com> With the addition of Medfield as a follow-up of Moorestown, more timer configurations are available to the kernel. This patch allows the optimal default configuration to be chosen and overwritten by cmdline as well. i.e. For Moorestown, percpu APB timers are default. For... 7 May 2010 14:30
