* [PATCH] uniform POLLRDHUP handling between epoll and poll/selectDavide Libenzi2006-04-11
| | | | | | | | | | | As reported by Michael Kerrisk, POLLRDHUP handling was not consistent between epoll and poll/select, since in epoll it was unmaskeable. This patch brings uniformity in POLLRDHUP handling.

* [PATCH] select: don't overflow if (SELECT_STACK_ALLOC % sizeof(long) != 0)Mitchell Blank Jr2006-04-11
| | | | | | | | | | | | | If SELECT_STACK_ALLOC is not a multiple of sizeof(long) then stack_fds[] would be shorter than SELECT_STACK_ALLOC bytes and could overflow later in the function. Fixed by simply rearranging the test later to work on sizeof(stack_fds) Currently SELECT_STACK_ALLOC is 256 so this doesn't happen, but it's nasty to have things like this hidden in the code. What if later someone decides to change SELECT_STACK_ALLOC to 300?

* [PATCH] timer initialisation fixAndrew Morton2006-04-11
| | | | | | | | | | | | | | | | | | We need the boot CPU's tvec_bases[] entry to be initialised super-early in boot, for early_serial_setup(). That runs within setup_arch(), before even per-cpu areas are initialised. The patch changes tvec_bases to use compile-time initialisation, and adds a separate array `tvec_base_done' to keep track of which CPU has had its tvec_bases[] entry initialised (because we can no longer use the zeroness of that tvec_bases[] entry to determine whether it has been initialised).

* [PATCH] No arch-specific strpbrk implementationsKyle McMartin2006-04-11
| | | | | | | | | | | | | | | While cleaning up parisc_ksyms.c earlier, I noticed that strpbrk wasn't being exported from lib/string.c. Investigating further, I noticed a changeset that removed its export and added it to _ksyms.c on a few more architectures. The justification was that "other arches do it." I think this is wrong, since no architecture currently defines __HAVE_ARCH_STRPBRK, there's no reason for any of them to be exporting it themselves. Therefore, consolidate the export to lib/string.c.

* [PATCH] Configurable NODES_SHIFTYasunori Goto2006-04-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for each arch. Its definition is sometimes configurable. Indeed, ia64 defines 5 NODES_SHIFT values in the current git tree. But it looks a bit messy. SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has been changeable by config. Suitable node's number may be changed in the future even if it is other architecture. So, I wrote configurable node's number. This patch set defines just default value for each arch which needs multi nodes except ia64. But, it is easy to change to configurable if necessary. On ia64 the number of nodes can be already configured in generic ia64 and SN2 config. But, NODES_SHIFT is defined for DIG64 and HP'S machine too. So, I changed it so that all platforms can be configured via CONFIG_NODES_SHIFT. It would be simpler.

* [PATCH] uml: safe migration path to the correct V3 COW formatPaolo 'Blaisorblade' Giarrusso2006-04-11
| | | | | | | | | | | | | | | | | - Correct the layout of all header versions - make all them well-specified for any external event. As we don't have 1-byte or 2-byte wide fields, the 32-bit layout (historical one) has no extra padding, so we can safely add __attribute__((packed)). - Add detection and reading of the broken 64-bit COW format which has been around for a while - to allow safe migration to the correct 32-bit format. Safe detection is possible, thanks to some luck with the existing format, and it works in practice.

* [PATCH] uml: make 64-bit COW files compatible with 32-bit onesPaolo 'Blaisorblade' Giarrusso2006-04-11
| | | | | | | | | | | | This is the minimal fix to make 64-bit UML binaries create 32-bit compatible COW files and read them. I've indeed tested that current code doesn't do this - the code gets SIGFPE for a division by a value read at the wrong place, where 0 is found.

* [PATCH] uml: memory hotplug cleanupsJeff Dike2006-04-11
| | | | | | | | | | | | | Change memory hotplug to use GFP_NOWAIT instead of GFP_ATOMIC, so that it will grab memory without sleeping, but doesn't try to use the emergency pools. A small list initialization suggested by Daniel Phillips - don't initialize lists which are just about to be list_add-ed.
