2008-02-14hrtimer: check relative timeouts for overflowThomas Gleixner5-22/+29
Various user space callers ask for relative timeouts. While we fixed that overflow issue in hrtimer_start(), the sites which convert relative user space values to absolute timeouts themself were uncovered. Instead of putting overflow checks into each place add a function which does the sanity checking and convert all affected callers to use it. Thanks to Frans Pop, who reported the problem and tested the fixes. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: Ingo Molnar <mingo@elte.hu> Tested-by: Frans Pop <elendil@planet.nl>
2008-02-14mlx4_core: Move table_find from fmr_alloc to fmr_enableJack Morgenstein1-8/+13
mlx4_table_find (for FMR MPTs) requires that ICM memory already be mapped. Before this fix, FMR allocation depended on ICM memory already being mapped for the MPT entry. If all currently mapped entries are taken, the find operation fails (even if the MPT ICM table still had more entries, which were just not mapped yet). This fix moves the mpt find operation to fmr_enable, to guarantee that any required ICM memory mapping has already occurred. Found by Oren Duer of Mellanox.

2008-02-14IB/mlx4: mlx4_ib_fmr_alloc() should call mlx4_fmr_enable()Jack Morgenstein1-1/+1
Currently mlx4_ib_fmr_alloc() calls mlx4_mr_enable() instead of mlx4_fmr_enable(). The two functions are equivalent at the moment, but this is not really correct (and the change is needed to fix a bug).

2008-02-14IPoIB: On P_Key change event, reset state properlyJack Morgenstein1-0/+1
In P_Key event handling, if the old P_Key is no longer available, the driver must call ipoib_ib_dev_stop() -- just as it does when the P_Key is still available (see procedure __ipoib_ib_dev_flush()). When a P_Key becomes available, the driver will perform ipoib_open(), which assumes that the QP is in RESET, the cm_id has been destroyed/deleted, etc. If ipoib_ib_dev_stop() is not called as described above, then these assumptions will be false, and the attempt to bring the interface up will fail. Found by Mellanox QA. Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

Fix a bug in the lv1_get_repository_node_value() routine of the PS3 bootwrapper. Changes in the PS3 system firmware 2.20 cause this bug to hang the system when branching from the bootwrapper to the kernel _start. Since the video system has not yet been enabled at the time the bug is hit, the system hangs with a blank screen. Earlier firmwares don't cause such a catastrophic failure, and so this bug went undetected. Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

2008-02-14sh: fix ioreadN_rep and iowriteN_repMagnus Damm1-6/+6
This patch is a fix to make sure readsN/writesN are used over insN/outsN for ioreadN_rep/iowriteN_rep. The current state of the sh io code is that mmio operations like readN/writeN and ioreadN/iowriteN are unaffected by the value of generic_io_base. This is different fom port based io like inN/outN which gets adjusted using the value in generic_io_base. Without this patch ioreadN_rep/iowriteN_rep get their addresses adjusted. The address for mmio access is adjusted using generic_io_base. This is wrong. The ata core code currently crashes if generic_io_base is set. This patch changes ioreadN_rep/iowriteN_rep to follow the same rules as the rest of the mmio operations, ie don't adjust using generic_io_base.

2008-02-14sh: asm/tlb.h needs linux/pagemap.h for CONFIG_SWAP=n.Paul Mundt1-0/+1
linux/swap.h really wants to include linux/pagemap.h in order to satisfy the page_cache_release()/release_pages() definition requirements when CONFIG_SWAP=n. Unfortunately the code in question contains: /* only sparc can not include linux/pagemap.h in this file * so leave page_cache_release and release_pages undeclared... */ #define free_page_and_swap_cache(page) \ page_cache_release(page) #define free_pages_and_swap_cache(pages, nr) \ release_pages((pages), (nr), 0); so it looks like we're stuck with doing it in asm/tlb.h instead, as others already do (ARM, CRIS, etc.).
