* [POWERPC] Fix MMIO ops to provide expected barrier behaviourPaul Mackerras2006-09-13
| | | | | | | | | | | | | | | | | | | | | | | | | | This changes the writeX family of functions to have a sync instruction before the MMIO store rather than after, because the generally expected behaviour is that the device receiving the MMIO store can be guaranteed to see the effects of any preceding writes to normal memory. To preserve ordering between writeX and readX, and to preserve ordering between preceding stores and the readX, the readX family of functions have had an sync added before the load. Although writeX followed by spin_unlock is not officially guaranteed to keep the writeX inside the spin-locked region unless an mmiowb() is used, there are currently drivers that depend on the previous behaviour on powerpc, which was that the mmiowb wasn't actually required. Therefore we have a per-cpu flag that is set by writeX, cleared by __raw_spin_lock and mmiowb, and tested by __raw_spin_unlock. If it is set, __raw_spin_unlock does a sync and clears it. This changes both 32-bit and 64-bit readX/writeX. 32-bit already has a sync in __raw_spin_unlock (since lwsync doesn't exist on 32-bit), and thus doesn't need the per-cpu flag. Tested on G5 (PPC970) and POWER5. Signed-off-by: Paul Mackerras <paulus@samba.org>

* [POWERPC] kdump: Support kernels having 64k page size.Sachin P. Sant2006-09-13
| | | | | | | | | | | | | | | This is required to generate proper core files using kdump on ppc64. Create a backup region of 64K size irrespective of the PAGE SIZE. At present 32K was used as backup size. In the case of 64K page size, second PT_LOAD segments starts at 32K and the first one is not page aligned. __ioremap() (crash_dump.c) fails if pfn = 0 which is the case for the second PT_LOAD segment. This is not an issue for 4K page size because the the first page (32K backup) is copied to second kernel memory and thus referencing with the second kernel pfn.

* | [PATCH] prevent timespec/timeval to ktime_t overflowThomas Gleixner2006-09-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Frank v. Waveren pointed out that on 64bit machines the timespec to ktime_t conversion might overflow. This is also true for timeval to ktime_t conversions. This breaks a "sleep inf" on 64bit machines. While a timespec/timeval with tx.sec = MAX_LONG is valid by specification the internal representation of ktime_t is based on nanoseconds. The conversion of seconds to nanoseconds overflows for seconds values >= (MAX_LONG / NSEC_PER_SEC). Check the seconds argument to the conversion and limit it to the maximum time which can be represented by ktime_t.

Davis Resolve ARM1136 VIPT non-aliasing cache coherency issues observed when using ptrace to set breakpoints and cleanup copy_{to,from}_user_page() while we're here as requested by Russell King because "it's also far too heavy on non-v6 CPUs". NOTES: 1. Only access_process_vm() calls copy_{to,from}_user_page(). 2. access_process_vm() calls get_user_pages() to pin down the "page". 3. get_user_pages() calls flush_dcache_page(page) which ensures cache coherency between kernel and userspace mappings of "page". However flush_dcache_page(page) may not invalidate I-Cache over this range for all cases, specifically, I-Cache is not invalidated for the VIPT non-aliasing case. So memory is consistent between kernel and user space mappings of "page" but I-Cache may still be hot over this range. IOW, we don't have to worry about flush_cache_page() before memcpy(). 4. Now, for the copy_to_user_page() case, after memcpy(), we must flush the caches so memory is consistent with kernel cache entries and invalidate the I-Cache if this mm region is executable. We don't need to do anything after memcpy() for the copy_from_user_page() case since kernel cache entries will be invalidated via the same process above if we access "page" again. The flush_ptrace_access() function (borrowed from SPARC64 implementation) is added to handle cache flushing after memcpy() for the copy_to_user_page() case. Signed-off-by: George G.

Both the AT91 and the ds1307 RTCs are enabled (rtc0 and rtc1 respectively). The ds1307 is used to initialize the system time, since it's battery-backed. From then on the AT91 RTC is used, since it's more capable (with both alarm and update irqs, and system wakeup capability) even though it needs manual initialization (symlink /dev/rtc to /dev/rtc0 for older versions of hwclock, then "hwclock --systohc") in an rc script or from inittab.

* | | [PATCH] fix NUMA interleaving for huge pagesNishanth Aravamudan2006-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since vma->vm_pgoff is in units of smallpages, VMAs for huge pages have the lower HPAGE_SHIFT - PAGE_SHIFT bits always cleared, which results in badd offsets to the interleave functions. Take this difference from small pages into account when calculating the offset. This does add a 0-bit shift into the small-page path (via alloc_page_vma()), but I think that is negligible. Also add a BUG_ON to prevent the offset from growing due to a negative right-shift, which probably shouldn't be allowed anyways. Tested on an 8-memory node ppc64 NUMA box and got the interleaving I expected.

* | | [PATCH] sgiioc4: fixup use of mmio opsJohn Keller2006-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix some bugs in the patch that converted the IOC4 driver from port IO ops to memio ops. http://marc.theaimsgroup.com/?l=linux-ide&m=114895892231438&w=2 Problems fixed are: - Call to default_hwif_mmiops() was not being done until _after_ first IO operation, resulting in the first IO operation being done as a port IO op, instead of memio. - request_region() calls needed to be request_mem_region() - Incomplete error case handling. - Non-usage of ioremap() and __iomem.

* | | [PATCH] powerpc: Fix PowerMac IRQ handling bugBenjamin Herrenschmidt2006-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The port to genirq & the new powerpc interrupt model in 2.6.18 introduced a bug in the legacy PowerMac PIC code (used on older machines) because of a typo potentially causing hangs due to interrupt storms. This fixes it, along with a performance issue causing us to do spurrious retriggers after masking an interrupt. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: "Antonino A.

* | | [PATCH] powerpc: More via-pmu backlight fixesBenjamin Herrenschmidt2006-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The via-pmu backlight code (introduced in 2.6.18) has various design issues causing crashes on machines using it like the old Wallstreet powerbook (Michael, the author, never managed to test on these and I just got my hand on one of those old beasts). This fixes them by no longer trying to hijack the backlight device of the frontmost framebuffer (causing that framebuffer to crash) but having it's own local bits instead. Might look weird but it's better that way on those old machines, at least as a last-minute fix for 2.6.18. We might rework the whole thing later. This patch also changes the way it gets notified of sleep and wakeup in order to properly shut the backlight down on sleep and bring it back on wakeup.
