Make a "menuconfig" out of the Kconfig objects "menu, ..., endmenu", so that the user can disable all the options in that menu at once instead of having to disable each option separately. Signed-off-by:

Fix following races: =========================================== 1. Write via ->write_proc sleeps in copy_from_user(). Module disappears meanwhile. Or, more generically, system call done on /proc file, method supplied by module is called, module dissapeares meanwhile. pde = create_proc_entry() if (!pde) return -ENOMEM; pde->write_proc = ... open write copy_from_user pde = create_proc_entry(); if (!pde) { remove_proc_entry(); return -ENOMEM; /* module unloaded */ } *boom* ========================================== 2. bogo-revoke aka proc_kill_inodes() remove_proc_entry vfs_read proc_kill_inodes [check ->f_op validness] [check ->f_op->read validness] [verify_area, security permissions checks] ->f_op = NULL; if (file->f_op->read) /* ->f_op dereference, boom */ NOTE, NOTE, NOTE: file_operations are proxied for regular files only. Let's see how this scheme behaves, then extend if needed for directories. Directories creators in /proc only set ->owner for them, so proxying for directories may be unneeded. NOTE, NOTE, NOTE: methods being proxied are ->llseek, ->read, ->write, ->poll, ->unlocked_ioctl, ->ioctl, ->compat_ioctl, ->open, ->release. If your in-tree module uses something else, yell on me.

COWed devices can't handle more than 32 (64 on x86_64) sectors in one request due to the size of the bitmap being carried around in the io_thread_req. Enforce that by telling the block layer not to put too many sectors in requests to COWed devices. Signed-off-by:

UML had two wrapper procedures for kmalloc, um_kmalloc and um_kmalloc_atomic because the flag constants weren't available in userspace code. kern_constants.h had made kernel constants available for a long time, so there is no need for these wrappers any more. Rather, userspace code calls kmalloc directly with the userspace versions of the gfp flags. kmalloc isn't a real procedure, so I had to essentially copy the inline wrapper around __kmalloc. vmalloc also had its own wrapper for no good reason. This is now gone. Signed-off-by:

run_helper and run_helper_thread had arguments which were the same in all callers. run_helper's stack_out was always NULL and run_helper_thread's stack_order was always 0. These are now gone, and the constants folded into the code. Also fixed leaks of the helper stack in the AIO and SIGIO code. Signed-off-by:

Cleanup of the SIGWINCH support. Some code and comment reformatting. The stack used for SIGWINCH threads was leaked. This is now fixed by storing it with the pid and other information, and freeing it when the thread is killed. If something goes wrong with a WIGWINCH thread, and this is discovered in the interrupt handler, the winch record would leak. It is now freed, except that the IRQ isn't freed. This is hard to do from interrupt context. This has the side-effect that the IRQ system maintains a reference to the freed structure, but that shouldn't cause a problem since the descriptor is disabled. register_winch_irq is now much better about cleaning up after an initialization failure.

If the host side of a console can't be opened, this will now produce visible error messages. enable_chan now returns a status and this is passed up to con_open and ssl_open, which will complain if anything went wrong. The default host device for the serial line driver is now a pts device rather than a pty device since lots of hosts have LEGACY_PTYS disabled. This had always been failing on such hosts, but silently. Signed-off-by:

Cleanup, mostly style violations. Tidied the includes. getmaster returns a real errno, which pty_open returns if there's a problem. The printks now have severity. Changed os_* calls to call libc directly. Signed-off-by:

Major tidying of the xterm console driver: got rid of the tt-mode gdb support tidied up the includes fixed lots of style violations replaced os_* calls with glibc calls in xterm.c all printk calls now have a severity indicator the error paths of xterm_open are closer to being right Signed-off-by:

DEBUG_SHIRQ generates spurious interrupts, triggering handlers such as mconsole_interrupt() or line_interrupt(). They expect data to be available to be read from their sockets/pipes, but in the case of spurious interrupts, the host didn't actually send anything, so UML hangs in read() and friends. Setting those fd's as O_NONBLOCK makes DEBUG_SHIRQ-enabled UML kernels boot and run correctly. Signed-off-by:

It is theoretically possible for a request to finish and be freed between writing it to the I/O thread and updating the sector count. In this case, the update will dereference a freed pointer. To avoid this, I delay the update until processing the next sg segment, when the request pointer is known to be good. Signed-off-by:

isa_bus_to_virt() is still needed in a few places (lance.c, at least). When we switch the kernel to using -Werror-implicit-function-declaration, the lack of isa_bus_to_virt() breaks alpha allmodconfig builds. Add isa_bus_to_virt() and deprecate the ezisting ISA APIs, though it might be better to define these functions as BUG(), since virt_to_bus/bus_to_virt just do wrong things on a number of machines.

Be (self-)consistent and use CONFIG_GDB_CONSOLE everywhere rather than using CONFIG_GDBSTUB_CONSOLE in some places and not others. This is also then consistent with other archs.
