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. Signed-off-by:

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? Signed-off-by:

We changed the wrong symbol. It's tty_insert_flip_string_flags() which is called from the previously-non-GPL'ed now-inlined tty_insert_flip_char(). Fix that up, and uninline tty_schedule_flip() while we're there. Cc: Tobias Powalowski <t.powa@gmx.de> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by:

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).

Some string functions were safely overrideable in lib/string.c, but their corresponding declarations in linux/string.h were not. Correct this, and make strcspn overrideable. Odds of someone wanting to do optimized assembly of these are small, but for the sake of cleanliness, might as well bring them into line with the rest of the file. Signed-off-by:

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.

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. See also: http://marc.theaimsgroup.com/?l=linux-kernel&m=114358010523896&w=2Signed-off-by:

The dasd driver sometimes print the misleading message "Can't offline dasd device with open count = 0". The reason why it can't offline the device in this case is that the device is still in the startup phase. Print a more meaningful message. Signed-off-by:

Since on some 64-bit systems __u64 is rightfully defined to unsigned long and GCC recognizes anyway unsigned long and unsigned long long as different, fix some types back to being unsigned long long to avoid warnings and errors (for prototype mismatch) on those systems.

Switch this proc from storing 4k of data (a whole path) on the stack to keeping it on the heap. Maybe it's not called in process context but only in early boot context (where in UML you have a normal process stack on the host) but just to be safe, fix it. While at it some little readability simplifications. Signed-off-by:

Little fix for error paths in this code. - Some bug come from conversion to os-Linux (open() doesn't follow the kernel -errno return convention, while the old code called os_open_file() which followed it). This caused the wrong return code to be printed. - Then be more precise about what happened and do some whitespace fixes. Signed-off-by:
