* sh64: Trivial build fixes.Paul Mundt2006-09-12
| | | | | | | | | While we've been sorting out the toolchain fiasco, some of the code has suffered a bit of bitrot. Building with GCC4 also brings up some more build warnings. Trivial fixes for both issues. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh64: Drop deprecated ISA tuning for legacy toolchains.Paul Mundt2006-09-12
| | | | | | | | | | | | | | | | | | | | | | | The original sh64 toolchains required that we tune the ISA level accordingly to not have head.S/entry.S blow up. With current toolchains, this is no longer the case, and the syntax magically changed as well, causing all current toolchains to die a horrible death. Incidentally, code generation in other parts of the kernel is now significantly complex enough that none of the older toolchains make it very far these days, so there's not even any point in preserving legacy compatability via as-option. This fixes a long-standing issue, as noted here: http://lkml.org/lkml/2005/1/5/223 Though at the time the current toolchains were too broken to make adjusting the tuning worthwhile.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both MMC and SD specifications specify (although a bit unclearly in the MMC case) that a sector size of 512 bytes must always be supported by the card.

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.

This causes a page pointer to be written beyond the end of the pagevec in nfs_read_data (or nfs_write_data). Fix this by making nfs_(read|write)_alloc() calculate the size of the pagevec array, and initialise data->npages. Also get rid of the redundant argument to nfs_commit_alloc().

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).

* | | [PATCH] Use the correct restart option for futex_lock_piThomas Gleixner2006-09-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current implementation of futex_lock_pi returns -ERESTART_RESTARTBLOCK in case that the lock operation has been interrupted by a signal. 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.

* | | [PATCH] IA64,sparc: local DoS with corrupted ELFsKirill Korotaev2006-09-08
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This prevents cross-region mappings on IA64 and SPARC which could lead to system crash. 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.
