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.

It seems, that previous solution based on 16 bytes (FIFO length size) read is still timing sensitive on genirq and fully preemptive kernels. The new solution is backuped by M9328 UM statement, that only 512 byte block are working properly and by 2.4.26 FreeScale's SDHC code.

They were correctly trapped for normal mmap() calls, but not for the kernel internal calls generated by executable loading. This code just moves the architecture-specific cross-region checks into an arch-specific "arch_mmap_check()" macro, and defines that for the architectures that needed it (ia64, sparc and sparc64). Architectures that don't have any special requirements can just ignore the new cross-region check, since the mmap() code will just notice on its own when the macro isn't defined.

This results in a return of -EINTR to userspace in case there is an handler for the signal. This is wrong, because userspace expects that the lock function does not return in any case of signal delivery. This was not caught by my insufficient test case, but triggered a nasty userspace problem in an high load application scenario. Unfortunately also glibc does not check for this invalid return value. Using -ERSTARTNOINTR makes sure, that the interrupted syscall is restarted. The restart block related code can be safely removed, as the possible timeout argument is an absolute time value.

It ends up returning -EIO. Here is the patch to fix it. If we really want to be paranoid, we can allow return values 0 (HOLE), 1 (we asked for one block) and return -EIO for more than 1 block. But I really don't see a reason for doing it - all we need is the block# here. (doesn't matter how many blocks are mapped). ext3_get_blocks_handle() returns number of blocks it mapped. It returns 0 in case of HOLE. ext3_getblk() should handle HOLE properly (currently its dumping warning stack and returning -EIO).

The changes come about due to these IRQs being displayed in two different registers, and needing to be acked and masked in both.
