* [SPARC64] arch/sparc64/kernel/unaligned.c: Use time_* macrosS.Çağlar Onur2008-02-171-1/+2
| | | | | | | | | | | | The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values. So following patch implements usage of the time_after() macro, defined at linux/jiffies.h, which deals with wrapping correctly Signed-off-by: S.Çağlar Onur <caglar@pardus.org.tr> Signed-off-by: David S.

| | | | | | | | | | | | | | This gives better heuristics for the cost of a multiply (fixed 5 cycles), rather than the 'ultrasparc' setting (variable, and unpredictable if the second argument is non-constant).

| | | | | | | | | | The makefile magic for installing the 32-bit vdso images on disk had a little error. A single-line change would fix that bug, but this does a little more to reduce the error-prone duplication of this bit of makefile variable magic.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit bdc807871d58285737d50dc6163d0feb72cb0dc2 broke the build for this config because the sim_defconfig selects CONFIG_HZ=250 but include/asm-ia64/param.h has an ifdef for the simulator to force HZ to 32. So we ended up with a kernel/timeconst.h set for HZ=250 ... which then failed the check for the right HZ value and died with: Drop the #ifdef magic from param.h and make force CONFIG_HZ=32 directly for the simulator.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we may not have a pci_dev for the device we need to access, we can't use pci_read_config_word. But raw_pci_read is an internal implementation detail; it's better to use the architected pci_bus_read_config_word interface. Using PCI_DEVFN instead of a mysterious constant helps reassure everyone that we really do intend to access device 8. [ Thanks to Grant Grundler for pointing out to me that this is exactly what the write immediately above this is doing -- enabling device 8 to respond to config space cycles. - Matthew Grant also says: "Can you also add a comment which points at the Intel documentation? The 'Intel E7320 Memory Controller Hub (MCH) Datasheet' at http://download.intel.com/design/chipsets/datashts/30300702.pdf Page 69 documents register F4h (DEVPRES1).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to PXA300/310 and PXA320 Developer manuals, the ASCR[RDH] "bit needs to be cleared as part of the software initialization coming out of any reset and coming out of D3". The latter requirement is addressed by commit "c4d1fb627ff3072", as for the former (coming out of any reset), the kernel relies on boot loaders and assumes that RDH bit is cleared there. Though, not all bootloaders follow the rule so we have to clear the bit in kernel. We clear the RDH bit in pxa3xx_init() function since it is always invoked after any reset. We also preserve D1S, D2S and D3S bits from being cleared in case we invoke pxa3xx_init() function not from normal hardware reset (e.g. kexec scenario), so these bits can be properly referenced later.

Always using legacy configuration mechanism for the legacy config space and extended mechanism (mmconf) for the extended config space is a simple and very logical approach. It's supposed to resolve all known mmconf problems. It still allows per-device quirks (tweaking dev->cfg_size). It also allows to get rid of mmconf fallback code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now, we check only the first 4k page for static required protections. This does not take overlapping regions into account. So we might end up setting the wrong permissions/protections for other parts of this large page. This can be optimized further, but correctness is the important part. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Switch the split page code to use the page pool. We do this unconditionally to avoid different behaviour with and without DEBUG_PAGEALLOC enabled. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>

The splitup ended in recursive calls to alloc_pages() when a page for a pte split was requested. Avoid the recursion with a preallocated page pool, which is used to split up large mappings and gets refilled in the return path of kernel_map_pages after the split has been done. The size of the page pool is adjusted to the available memory. This part just implements the page pool and the initialization w/o using it yet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some suspend and hibernation files in arch/x86/power there are comments referring to arch/x86-64 and arch/i386 . Update them to reflect the current code layout. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
