2009-10-14[S390] tape390: Fix request queue handling in block driverMichael Holzheu
When setting a channel attached tape online under Linux 2.6.31, the "vol_id" process from udev hangs in sync_page(): 2 sync_page+144 [0x1dfaac] 3 __wait_on_bit_lock+194 [0x58c23e] 4 __lock_page+116 [0x1df9dc] 5 truncate_inode_pages_range+728 [0x1ed7cc] 6 __blkdev_put+244 [0x25f738] 7 __fput+300 [0x229c4c] 8 filp_close+122 [0x225a3a] The reason for that is an error in the request queue handling. It can happen that we fetch a request, but do not process it further because the number of queued requests exceeds TAPEBLOCK_MIN_REQUEUE. To fix this, we should call blk_peek_request() instead of blk_fetch_request() in the while condition and fetch the request in the loop body afterwards. This bug was introduced with the patch "block: implement and enforce request peek/start/fetch" (9934c8c04561413609d2bc38c6b9f268cba774a4) Signed-off-by: Michael Holzheu <holzheu@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2009-10-14[S390] hypfs: Use subcode 6 if subcode 7 is not availableMichael Holzheu
Hypfs never worked on systems that only provide D204 subcode 6. In these cases we nevertheless used subcode 7. With this fix, we use subcode 6, if it is available and the system does not provide subcode 7.

2009-10-14tracing: Move syscalls metadata handling from arch to coreFrederic Weisbecker
Most of the syscalls metadata processing is done from arch. But these operations are mostly generic accross archs. Especially now that we have a common variable name that expresses the number of syscalls supported by an arch: NR_syscalls, the only remaining bits that need to reside in arch is the syscall nr to addr translation. v2: Compare syscalls symbols only after the "sys" prefix so that we avoid spurious mismatches with archs that have syscalls wrappers, in which case syscalls symbols have "SyS" prefixed aliases.

2009-10-14tracing: Enable "__cold" functionsJiri Olsa
Based on the commit: a586df06 "x86: Support __attribute__((__cold__)) in gcc 4.3" some of the functions goes to the ".text.unlikely" section. Looks like there's not many of them (I found printk, panic, __ssb_dma_not_implemented, fat_fs_error), but still worth to include I think.

2009-10-14tracing: Enable records during the module loadJiri Olsa
I was debuging some module using "function" and "function_graph" tracers and noticed, that if you load module after you enabled tracing, the module's hooks will convert only to NOP instructions. The attached patch enables modules' hooks if there's function trace allready on, thus allowing to trace module functions.

2009-10-14function-graph/x86: Replace unbalanced ret with jmpSteven Rostedt
The function graph tracer replaces the return address with a hook to trace the exit of the function call. This hook will finish by returning to the real location the function should return to. But the current implementation uses a ret to jump to the real return location. This causes a imbalance between calls and ret. That is the original function does a call, the ret goes to the handler and then the handler does a ret without a matching call. Although the function graph tracer itself still breaks the branch predictor by replacing the original ret, by using a second ret and causing an imbalance, it breaks the predictor even more. This patch replaces the ret with a jmp to keep the calls and ret balanced. I tested this on one box and it showed a 1.7% increase in performance. Another box only showed a small 0.3% increase. But no box that I tested this on showed a decrease in performance by making this change.

After a reboot on an ARM1176 which amounts to a softreset, it has been noted that the ALSA driver does not get registered and the probe fails with the error "aaci-pl041 fpga:04: ac97 read back fail". In the process of reading from a register the SL1TxBusy bit is set indicating that the transceiver is busy and remains so until the default timeout occurs. Set the Power down register 0x26 to an arbitrary value as specified in the PL041 manual (page: 3-18) so that AACISL1TX/AACISL2TX registers take their default state.

2009-10-13x86/paravirt: Use normal calling sequences for irq enable/disableJeremy Fitzhardinge
Bastian Blank reported a boot crash with stackprotector enabled, and debugged it back to edx register corruption. For historical reasons irq enable/disable/save/restore had special calling sequences to make them more efficient. With the more recent introduction of higher-level and more general optimisations this is no longer necessary so we can just use the normal PVOP_ macros.

This too follows the ARM change, given that the issue at hand applies to all platforms that implement lazy D-cache writeback. This fixes up the case when a page mapping disappears between the flush_dcache_page() call (when PG_dcache_dirty is set for the page) and the update_mmu_cache() call -- such as in the case of swap cache being freed early. This kills off the mapping test in update_mmu_cache() and switches to simply testing for PG_dcache_dirty.
