It now compiles and works for the legacy non-devicetree case, but with device tree booting there's now regression during boot: [ 5.200836] Freeing init memory: 332K [ 6.881744] Unable to handle kernel NULL pointer dereference at virtual address 00000030 [ 6.890258] pgd = ee664000 [ 6.893096] [00000030] *pgd=ae64f831, *pte=00000000, *ppte=00000000 [ 6.899688] Internal error: Oops: 17 [#1] SMP ARM [ 6.904632] Modules linked in: [ 6.907836] CPU: 1 Not tainted (3.6.0-rc4-00207-gc893c8c-dirty #485) [ 6.914916] PC is at serial_omap_start_tx+0x60/0x98 [ 6.920043] LR is at serial_omap_start_tx+0x44/0x98 [ 6.925140] pc : [<c0316978>] lr : [<c031695c>] psr: 60000193 [ 6.925140] sp : ee661e80 ip : 00000060 fp : a0000113 [ 6.937194] r10: ef3c0010 r9 : ee798800 r8 : 00000072 [ 6.942687] r7 : ef3d7472 r6 : 00000002 r5 : 00000007 r4 : ef3c0010 [ 6.949523] r3 : 00000000 r2 : 00000004 r1 : 00000007 r0 : ef0da008 [ 6.956390] Flags: nZCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment user [ 6.963958] Control: 10c53c7d Table: ae66404a DAC: 00000015 [ 6.970001] Process modprobe (pid: 715, stack limit = 0xee6602f8) [ 6.976379] Stack: (0xee661e80 to 0xee662000) [ 6.980957] 1e80: ee798800 ef3c0010 20000113 c030fcb4 00000000 ef3eead0 00000000 c0310544 [ 6.989562] 1ea0: ef3eead0 ee798800 00000fff 00000073 ee798d94 ef3d7400 ee660000 ee7989b8 [ 6.998138] 1ec0: ef3d7400 c02fa090 00000073 ef3d7400 ee798800 ee798800 ef0ccdc0 c02fb8e4 [ 7.006713] 1ee0: beaa07bc ee798a2c beaa07bc 00000000 ef38aa00 c00778a0 ee798a4c ee798a4c [ 7.015319] 1f00: ee798d4c ef0ccdc0 00000073 00000073 ee798800 b6f19000 ee660000 00000400 [ 7.023895] 1f20: 00000000 c02f775c c02fb7a8 ef1f6840 ee661f80 ef0ccdc0 00000000 ef0ccdc0 [ 7.032470] 1f40: 00000073 b6f19000 ee661f80 00000073 ee660000 00000000 beaa07bc c010b580 [ 7.041046] 1f60: ef38aa00 00000001 00000000 00000000 ef0ccdc0 b6f19000 00000073 c010b6e4 [ 7.049652] 1f80: 00000000 00000000 beaa0888 00000000 00000073 beaa0888 00000073 00000004 [ 7.058227] 1fa0: c0014308 c0014160 00000073 beaa0888 00000000 b6f19000 00000073 00000000 [ 7.066802] 1fc0: 00000073 beaa0888 00000073 00000004 b6f19000 00000000 b6ee271d beaa07bc [ 7.075408] 1fe0: 00000000 beaa01c0 b6e2c874 b6e8015c 60000110 00000000 aaaaaaaa aaeaaaaa [ 7.083984] [<c0316978>] (serial_omap_start_tx+0x60/0x98) from [<c030fcb4>] (uart_start+0x68/0x6c) [ 7.093414] [<c030fcb4>] (uart_start+0x68/0x6c) from [<c0310544>] (uart_write+0xcc/0xf4) [ 7.101928] [<c0310544>] (uart_write+0xcc/0xf4) from [<c02fa090>] (process_output_block+0xc0/0x17c) [ 7.111419] [<c02fa090>] (process_output_block+0xc0/0x17c) from [<c02fb8e4>] (n_tty_write+0x13c/0x2ac) [ 7.121215] [<c02fb8e4>] (n_tty_write+0x13c/0x2ac) from [<c02f775c>] (tty_write+0x13c/0x228) [ 7.130065] [<c02f775c>] (tty_write+0x13c/0x228) from [<c010b580>] (vfs_write+0xb0/0x144) [ 7.138671] [<c010b580>] (vfs_write+0xb0/0x144) from [<c010b6e4>] (sys_write+0x40/0x70) [ 7.147094] [<c010b6e4>] (sys_write+0x40/0x70) from [<c0014160>] (ret_fast_syscall+0x0/0x3c) [ 7.155944] Code: e6ff1075 e18310b2 e5940180 e5903084 (e5933030) [ 7.162353] ---[ end trace 8cfe94e3de797bda ]--- -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

when rebasing patches on top of Greg's tty-next, it looks like automerge broke a few things which I didn't catch (for whatever reason I didn't have OMAP Serial enabled on .config) so I ended up breaking the build on Greg's tty-next branch. Fix the breakage by re-adding the three missing members on struct uart_omap_port.
