* [PATCH] IPMI: misc fixesCorey Minyard2006-12-10
| | | | | | | | | | | | | | | | | | Fix various problems pointed out by Andrew Morton and others: * platform_device_unregister checks for NULL, no need to check here. * Formatting fixes. * Remove big macro and convert to a function. * Use strcmp instead of defining a broken case-insensitive comparison, and make the output parameter info match the case of the input one (change "I/O" to "i/o"). * Return the length instead of 0 from the hotmod parameter handler. * Remove some unused cruft. * The trydefaults parameter only has to do with scanning the "standard" addresses, don't check for that on ACPI.

* [PATCH] read_zero_pagealigned() locking fixHugh Dickins2006-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | Ramiro Voicu hits the BUG_ON(!pte_none(*pte)) in zeromap_pte_range: kernel bugzilla 7645. Right: read_zero_pagealigned uses down_read of mmap_sem, but another thread's racing read of /dev/zero, or a normal fault, can easily set that pte again, in between zap_page_range and zeromap_page_range getting there. It's been wrong ever since 2.4.3. The simple fix is to use down_write instead, but that would serialize reads of /dev/zero more than at present: perhaps some app would be badly affected. So instead let zeromap_page_range return the error instead of BUG_ON, and read_zero_pagealigned break to the slower clear_user loop in that case - there's no need to optimize for it. Use -EEXIST for when a pte is found: BUG_ON in mmap_zero (the other user of zeromap_page_range), though it really isn't interesting there. And since mmap_zero wants -EAGAIN for out-of-memory, the zeromaps better return that than -ENOMEM.
