* | | x86_64: Fix readahead/sync_file_range/fadvise64 compat callsAndi Kleen2007-06-202-3/+22
|/ / | | | | | | | | | | | | | | | | | | | | | | Correctly convert the u64 arguments from 32bit to 64bit. Pointed out by Heiko Carstens. I guess this proves Linus' theory that nobody uses the more exotic Linux specific syscalls. It wasn't discovered by a user.

* | [POWERPC] rheap - eliminates internal fragments caused by alignmentLi Yang2007-06-191-19/+29
| | | | | | | | | | | | | | | | | | | | | | | | The patch adds fragments caused by rh_alloc_align() back to free list, instead of allocating the whole chunk of memory. This will greatly improve memory utilization managed by rheap. It solves MURAM not enough problem with 3 UCCs enabled on MPC8323.

| * | sh: Handle -ERESTART_RESTARTBLOCK for restartable syscalls.Paul Mundt2007-06-191-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current implementation only handles -ERESTARTNOHAND, whereas we also need to handle -ERESTART_RESTARTBLOCK in the handle_signal() case for restartable system calls. As noted by Carl: This fixes the LTP test nanosleep03 - the current kernel causes -ERESTART_RESTARTBLOCK to reach user space rather than the correct -EINTR.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As Russell helpfully pointed out on linux-arch: http://marc.info/?l=linux-arch&m=118208089204630&w=2 We were missing the oops_enter/exit() in the sh die() implementation.

* uml: remove PAGE_SIZE from libc codeJeff Dike2007-06-165-16/+22
| | | | | | | | | | | | | | | | | Distros seem to be removing PAGE_SIZE from asm/page.h. So, the libc side of UML should stop using it. I replace it with UM_KERN_PAGE_SIZE, which is defined to be the same as PAGE_SIZE on the kernel side of the house. I could also use getpagesize(), but it's more important that UML have the same value of PAGE_SIZE everywhere. It's conceivable that it could be built with a larger PAGE_SIZE, and use of getpagesize() would break that badly. PAGE_MASK got the same treatment, as it is closely tied to PAGE_SIZE.

This took a long time to figure out and both insight from myself, Kyle McMartin, and James Bottomley were required to narrow down which bit of code could have this race condition. The symptom was interrupts stopped getting delivered while some workload was generating IO interrupts on two different CPUs. One of the interrupt sources would get masked off and stay unmasked. Problem was global_ack_eiem was accessed with read/modified/write sequence and not protected by a spinlock. PA-RISC doesn't need a global ack flag though. External Interrupts are _always_ delivered to a single CPU (except for "global broadcast interrupt" which AFAIK currently is not used.) So we don't have to worry about any given IRQ vector getting delivered to more than one CPU. Tested on a500 and rp34xx boxen. rsync to/from gsyprf11 (a500) would lock up the box since NIC (tg3) interrupt and SCSI (sym2) were on "opposite" CPUs (2 CPU system). Put them on the same CPU or apply this patch and 10GB of data would rsync completely.
