Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths.
Now, the one where most of tty_port_tty_get gets removed: tty_flip_buffer_push.
IOW we also closed all the races in drivers not using tty_port_tty_get at all yet.
Also we move tty_flip_buffer_push declaration from include/linux/tty.h to include/linux/tty_flip.h to all others while we are changing it anyway.

TTY: irq: Remove IRQF_DISABLED
Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a: genirq: Warn when handler enables interrupts]).
So now this flag is a NOOP and can be removed.

tty: move drivers/serial/ to drivers/tty/serial/
The serial drivers are really just tty drivers, so move them to drivers/tty/ to make things a bit neater overall.
This is part of the tty/serial driver movement proceedure as proposed by Arnd Bergmann and approved by everyone involved a number of months ago.

tty: serial: icom: switch from 'pci_' to 'dma_' API The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below and has been hand modified to replace GFP_ with a correct flag. It has been compile tested. When memory is allocated in 'get_port_memory()', GFP_KERNEL can be used because it is only called from a probe function and no lock is acquired. The call chain is: icom_probe (the probe function) --> icom_load_ports --> get_port_memory When memory is allocated in 'load_code()', GFP_KERNEL can be used because it is only called from a .startup function. icom_open (the .startup function of struct uart_ops) --> startup --> load_code .startup functions are protected using a semaphore and no spinlock is taken. @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3; @@ - pci_alloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3; @@ - pci_zalloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3, e4; @@ - pci_free_consistent(e1, e2, e3, e4) + dma_free_coherent(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4, e5; @@ - pci_map_page(e1, e2, e3, e4, e5) + dma_map_page(&e1->dev, e2, e3, e4, e5) @@ expression e1, e2, e3, e4; @@ - pci_unmap_page(e1, e2, e3, e4) + dma_unmap_page(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_cpu(e1, e2, e3, e4) + dma_sync_single_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_device(e1, e2, e3, e4) + dma_sync_single_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_cpu(e1, e2, e3, e4) + dma_sync_sg_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_device(e1, e2, e3, e4) + dma_sync_sg_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2; @@ - pci_dma_mapping_error(e1, e2) + dma_mapping_error(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Link: https://lore.kernel.org/r/20200806060507.730142-1-christophe.jaillet@wanadoo.fr Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

tty: serial: Remove redundant license text Now that the SPDX tag is in all tty files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

tty: add SPDX identifiers to all remaining files in drivers/tty/ It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/tty files files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

tty: serial: constify uart_ops structures Declare uart_ops structures as const as they are only stored in the ops field of an uart_port structure. This field is of type const, so uart_ops structures having this property can be made const too. File size details before and after patching. First line of every .o file shows the file size before patching and second line shows the size after patching. text data bss dec hex filename 2977 456 64 3497 da9 drivers/tty/serial/amba-pl010.o 3169 272 64 3505 db1 drivers/tty/serial/amba-pl010.o 3109 456 0 3565 ded drivers/tty/serial/efm32-uart.o 3301 272 0 3573 df5 drivers/tty/serial/efm32-uart.o 10668 753 1 11422 2c9e drivers/tty/serial/icom.o 10860 561 1 11422 2c9e drivers/tty/serial/icom.o 23904 408 8 24320 5f00 drivers/tty/serial/ioc3_serial.o 24088 224 8 24320 5f00 drivers/tty/serial/ioc3_serial.o 10516 560 4 11080 2b48 drivers/tty/serial/ioc4_serial.o 10709 368 4 11081 2b49 drivers/tty/serial/ioc4_serial.o 7853 648 1216 9717 25f5 drivers/tty/serial/mpsc.o 8037 456 1216 9709 25ed drivers/tty/serial/mpsc.o 10248 456 0 10704 29d0 drivers/tty/serial/omap-serial.o 10440 272 0 10712 29d8 drivers/tty/serial/omap-serial.o 8122 532 1984 10638 298e drivers/tty/serial/pmac_zilog.o 8306 340 1984 10630 2986 drivers/tty/serial/pmac_zilog.o 3808 456 0 4264 10a8 drivers/tty/serial/pxa.o 4000 264 0 4264 10a8 drivers/tty/serial/pxa.o 21781 3864 0 25645 642d drivers/tty/serial/serial-tegra.o 22037 3608 0 25645 642d drivers/tty/serial/serial-tegra.o 2481 456 96 3033 bd9 drivers/tty/serial/sprd_serial.o 2673 272 96 3041 be1 drivers/tty/serial/sprd_serial.o 5534 300 512 6346 18ca drivers/tty/serial/vr41xx_siu.o 5630 204 512 6346 18ca drivers/tty/serial/vr41xx_siu.o 6730 1576 128 8434 20f2 drivers/tty/serial/vt8500_serial.o 6986 1320 128 8434 20f2 drivers/tty/serial/vt8500_serial.o Cross compiled for mips architecture. 3005 488 0 3493 da5 drivers/tty/serial/pnx8xxx_uart.o 3189 304 0 3493 da5 drivers/tty/serial/pnx8xxx_uart.o 4272 196 1056 5524 1594 drivers/tty/serial/dz.o 4368 100 1056 5524 1594 drivers/tty/serial/dz.o 6551 144 16 6711 1a37 drivers/tty/serial/ip22zilog.o 6647 48 16 6711 1a37 drivers/tty/serial/ip22zilog.o 9612 428 1520 11560 2d28 drivers/tty/serial/serial_txx9.o 9708 332 1520 11560 2d28 drivers/tty/serial/serial_txx9.o 4156 296 16 4468 1174 drivers/tty/serial/ar933x_uart.o 4252 200 16 4468 1174 drivers/tty/serial/ar933x_uart.o Cross compiled for arm archiecture. 11716 1780 44 13540 34e4 drivers/tty/serial/sirfsoc_uart.o 11808 1688 44 13540 34e4 drivers/tty/serial/sirfsoc_uart.o 13352 596 56 14004 36b4 drivers/tty/serial/amba-pl011.o 13444 504 56 14004 36b4 drivers/tty/serial/amba-pl011.o Cross compiled for sparc architecture. 4664 528 32 5224 1468 drivers/tty/serial/sunhv.o 4848 344 32 5224 1468 drivers/tty/serial/sunhv.o 8080 332 28 8440 20f8 drivers/tty/serial/sunzilog.o 8184 228 28 8440 20f8 drivers/tty/serial/sunzilog.o Cross compiled for ia64 architecture. 10226 549 472 11247 2bef drivers/tty/serial/sn_console.o 10414 365 472 11251 2bf3 drivers/tty/serial/sn_console.o The files drivers/tty/serial/zs.o, drivers/tty/serial/lpc32xx_hs.o and drivers/tty/serial/lantiq.o did not compile.
