| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From cefcdab08d1c9636c4a7290bc2bbe937d051bce4 Mon Sep 17 00:00:00 2001 From: Volker Ernst <volker.ernst@txtr.com> Date: Mon, 26 Apr 2010 22:51:07 +0200 Subject: [PATCH] ARM: mx3: Fix a race condition in mxcmmc This fixes a race condition regarding interrupt bits in the SDHC controller driver code. In case of PIO-transfer it does not clear SDHC-status bit#11/12 in the INT-handler anymore. INT-handler might be called during an ongoing PIO-data-transfer (with some other INT-flag set) and PIO-transfer depends on these bits being set to detect the end of the data-transfer. This also means that at the end of PIO- transfer that PIO-software has to clear these bits itself. However in case of DMA-transfer these bits have to be cleared in the INT-handler, because they are used to generate INTs then. Works solid, no more problems here, can transfer big files.

| * ARM: MXC: mxcmmc: work around a bug in the SDHC busy line handlingDaniel Mack2010-04-143-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MX3 SoCs have a silicon bug which corrupts CRC calculation of multi-block transfers when connected SDIO peripheral doesn't drive the BUSY line as required by the specs. One way to prevent this is to only allow 1-bit transfers. Another way is playing tricks with the DMA engine, but this isn't mainline yet. So for now, we live with the performance drawback of 1-bit transfers until a nicer solution is found. This patch introduces a new host controller callback 'init_card' which is for now only called from mmc_sdio_init_card().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On i.MX21 SoCs, if the NFC_CONFIG1:NFC_INT_MASK bit is set, NFC_CONFIG2:NFC_INT always reads out zero, even if an operation is completed. This patch uses enable_irq and disable_irq_nosync instead of NFC_CONFIG1:NFC_INT_MASK to mask NFC interrupts. This allows NFC_CONFIG2:NFC_INT to also be used to detect operation completion on i.MX21. The i.MX21 NFC does not signal reset completion using NFC_CONFIG1:NFC_INT_MASK, so instead reset completion is tested by checking if NFC_CONFIG2 becomes 0.

We're depending here on the boot time that we use to generate the stateid being monotonic, but get_seconds() is not necessarily. We still depend at least on boot_time being different every time, but that is a safer bet. We have a few reports of errors that might be explained by this problem, though we haven't been able to confirm any of them. But the minor gain of distinguishing expired from stale errors seems not worth the risk. Conflicts: fs/nfsd/nfs4state.c Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
| * | nfsd: safer initialization order in find_file()Pavel Emelyanov2010-05-181-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The alloc_init_file() first adds a file to the hash and then initializes its fi_inode, fi_id and fi_had_conflict. The uninitialized fi_inode could thus be erroneously checked by the find_file(), so move the hash insertion lower. The client_mutex should prevent this race in practice; however, we eventually hope to make less use of the client_mutex, so the ordering here is an accident waiting to happen. I didn't find whether the same can be true for two other fields, but the common sense tells me it's better to initialize an object before putting it into a global hash table :) Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: J.

The problem is that once I turn off e.g. NFSD-V4 this call returns -1 which is true from the callers POV which is wrong. The proposal is to report false in that case.

| * | nfsd4: fix bare destroy_session null dereferenceJ. Bruce Fields2010-05-081-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's legal to send a DESTROY_SESSION outside any session (as the only operation in a compound), in which case cstate->session will be NULL; check for that case. While we're at it, move these checks into a separate helper function. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
