Siva Rebbagondla f700546682 rsi: fix nommu_map_sg overflow kernel panic ... Following overflow kernel panic is observed on some platforms while loading the driver. It is fixed if dynamically allocated memory is passed to SDIO instead of static one [ 927.513963] nommu_map_sg: overflow 17d54064ba7c+20 of device mask ffffffff [ 927.517712] Modules linked in: rsi_sdio(+) cmac bnep arc4 rsi_91x mac80211 cfg80211 btrsi rfcomm bluetooth ecdh_generic snd_soc_sst_bytcr_rt5660 [ 927.517861] CPU: 0 PID: 1624 Comm: insmod Tainted: G W 4.15.0-1000 #1 [ 927.517870] RIP: 0010:sdhci_send_command+0x5f0/0xa90 [sdhci] [ 927.517873] RSP: 0000:ffffac3fc064b6d8 EFLAGS: 00010086 [ 927.517895] Call Trace: [ 927.517908] ? __schedule+0x3cd/0x890 [ 927.517915] ? mod_timer+0x17b/0x3c0 [ 927.517922] sdhci_request+0x7c/0xf0 [sdhci] [ 927.517928] __mmc_start_request+0x5a/0x170 [ 927.517932] mmc_start_request+0x74/0x90 [ 927.517936] mmc_wait_for_req+0x87/0xe0 [ 927.517940] mmc_io_rw_extended+0x2fd/0x330 [ 927.517946] ? mmc_wait_data_done+0x30/0x30 [ 927.517951] sdio_io_rw_ext_helper+0x160/0x210 [ 927.517956] sdio_writesb+0x1d/0x20 [ 927.517966] rsi_sdio_write_register_multiple+0x68/0x110 [rsi_sdio] [ 927.517976] rsi_hal_device_init+0x357/0x910 [rsi_91x] [ 927.517983] ? rsi_hal_device_init+0x357/0x910 [rsi_91x] [ 927.517990] rsi_probe+0x2c6/0x450 [rsi_sdio] [ 927.517995] sdio_bus_probe+0xfc/0x110 [ 927.518000] driver_probe_device+0x2b3/0x490 [ 927.518005] __driver_attach+0xdf/0xf0 [ 927.518008] ? driver_probe_device+0x490/0x490 [ 927.518014] bus_for_each_dev+0x6c/0xc0 [ 927.518018] driver_attach+0x1e/0x20 [ 927.518021] bus_add_driver+0x1f4/0x270 [ 927.518028] ? rsi_sdio_ack_intr+0x50/0x50 [rsi_sdio] [ 927.518031] driver_register+0x60/0xe0 [ 927.518038] ? rsi_sdio_ack_intr+0x50/0x50 [rsi_sdio] [ 927.518041] sdio_register_driver+0x20/0x30 [ 927.518047] rsi_module_init+0x16/0x40 [rsi_sdio] Signed-off-by: Siva Rebbagondla <siva.rebbagondla@redpinesignals.com> Signed-off-by: Amitkumar Karwar <amit.karwar@redpinesignals.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>		2018-04-24 20:25:57 +03:00
