This patch uses the rcu_assign_pointer() API to eliminate a number of explicit memory barriers from the SysV IPC code that uses RCU. It also restructures the ipc_ids structure so that the array size is stored in the same memory block as the array itself (see the new struct ipc_id_ary). This prevents the race that the earlier code was subject to, where a reader could see a mismatch between the size and the actual array. With the size stored with the array, the possibility of mismatch is eliminated -- with out the need for careful ordering and explicit memory barriers. This has been tested successfully on i386 and ppc64. Signed-off-by: <paulmck@us.ibm.com> Signed-off-by:

This patch adds the rcu_assign_pointer() API that helps reduce the need for explicit memory barriers in code that uses RCU. This API buries the required memory barriers in a macro that also does the assignment. This has been tested successfully on i386 and ppc64. Signed-off-by: <paulmck@us.ibm.com> Signed-off-by:

The patch just removes all trailing whitespaces, there are no actual code changes. I've a script to remove them from my sources now, that should kill those no-op whitespace changes in my patches after merging this initial cleanup. Signed-off-by:

After William did the remap_pfn_range change, a very common pattern became: page = page_to_pfn(vmalloc_to_page((void *)pos)); if (remap_pfn_range(vma, start, page, PAGE_SIZE, PAGE_SHARED)) { the patch below adds a very simple helper, vmalloc_to_pfn() to simplify this a bit. Signed-off-by: -

The patch below unexports raise_softirq(). raise_softirq() is not the right api for drivers to use, instead raise_softirq_irqoff() is, and thankfully all in-kernel code is using that variant already. To avoid future "accidents", unexport. Acked-by:

The typecast (const unsigned short *) &c in fbcon_putc is not correct for big-endian machines. This problem manifests as a black cursor that can be used to erase the console screen contents. The correct fix is to use scr_writew instead. Signed-off-by:

- fixes crashes when changing video modes/switching away from X on ppc - fixes random crashes when scrolling in e.g. vi - improves on the NV30 support - reintroduces noaccel (not perfect but helps a lot for debugging) - converts MODULE_PARM to module_param - cleans up some printks, FB_ACCELF_TEXT cruft Most of this is taken from either XFree86 4.3 or BenH's 2.4 ppc tree. From: Antonino Daplas <adaplas@pol.net> - adjust pixmap->scan_align to 1 and use cfb_* drawing functions if FBINFO_HWACCEL_DISABLED is set Signed-off-by:

Nothing good will happen if we try to ioremap and use a zero-sized frame buffer. I observed this problem on an ia64 sx1000 box, where the BIOS doesn't run the option ROM. If we try to continue, radeonfb just gets hopelessly confused because the card isn't initialized correctly. Signed-off-by:

kswapd is still sometimes going into loops. The problem seemed to be happening on systems with zero inactive pages in ZONE_DMA, so pages_scanned could never be increased, all_unreclaimable would never be set, and kswapd would never break. So change pages_scanned to be a count of the number of _active_ list pages scanned rather than inactive. This has been reported to solve the problems. This is not subject to the reverse problem where one might have zero active list pages, because inactive pages are either be reclaimed, or put onto the active list. I think it is reasonable to have all_unreclaimed trigger based on the amount of active list scanning rather than inactive. Signed-off-by:

pm_access does nothing these days, and looks ugly. This removes it from vt.c. That actually looks like last user in the tree; it should be possible to kill pm_access completely after 2.6.10. Ouch and add warning to obsolete pm.txt file. Signed-off-by:

This preserves the ioreadX() == inX() semantics (same as i386), since it's not clear that the speedup of omitting the mf.a for port operations is worth the risk of breaking drivers. Signed-off-by:

Forthcoming IBM boxes will be using Nocona and/or Opteron chips in clustered mode to get beyond 8 CPUs. In fact, there are plans to try for 128 CPUs when the Tulsa chip comes out. Thus, there are a fair number of signed vs. unsigned changes in the patch. Thanks to the HPET timer and some HW changes, I've been able to remove the MPS/ACPI string comparisons from the detection code. Instead, it scans bios_cpu_apicid and uses simple heuristics to select the correct IRQ delivery mode. No need for a config option. Hurrah! Likewise, I've been able to avoid the preprocessor tricks that the i386 sub-arch needed to build with one or more sub-arches. Reluctantly-Acked-by:
