UML guest processes now get correct siginfo_t for SIGTRAP, SIGFPE, SIGILL and SIGBUS. Specifically, si_addr and si_code are now correct where previously they were si_addr = NULL and si_code = 128.

Only 3 out of 63 do not. Renamed the current variant to __set_current_blocked(), added set_current_blocked() that will exclude unblockable signals, switched open-coded instances to it. Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

Instead of using chip->release() we can achieve the same using a simple wrapper for free_irq(). We have already um_request_irq(), so um_free_irq() is the perfect counterpart. Signed-off-by: NRichard Weinberger <richard@nod.at> Reviewed-by: NThomas Gleixner <tglx@linutronix.de>

The current __swp_type() function uses a too small bitshift. Using more than one swap files causes bad pages because the type bits clash with other page flags. CC: stable@kernel.org Analyzed-by: NHugh Dickins <hughd@google.com> Signed-off-by: NRichard Weinberger <richard@nod.at>

UML uses the _PAGE_NEWPAGE flag to mark pages which are not jet installed on the host side using mmap(). pte_same() has to ignore this flag, otherwise unuse_pte_range() is unable to unuse the page because two identical page tables entries with different _PAGE_NEWPAGE flags would not match and swapoff() would never return.

Historical prepare_to_copy() is mostly a no-op, duplicated for majority of the architectures and the rest following the x86 model of flushing the extended register state like fpu there. Remove it and use the arch_dup_task_struct() instead.

it's x86-only and we have no business playing with it in asm/mmu.h; make the latter have struct uml_arch_mm_context arch; instead of struct uml_ldt ldt; and let arch/<subarch>/um/asm/mm_context.h decide what'll be in there. While we are at it, kill host_ldt.h - it's not needed in part of places that include it (we want asm/ldt.h in those) and it can be trivially expanded into the single remaining one.
