For some of the larger sizes we permitted spanning pages across several PTEs, but this turned out to not be generally useful. This reverts the sh hugetlbpage interface to something more sensible using huge pages at single PTE granularity. Signed-off-by: -

We had a special .stack section in the ld script that was being used to position r15 initially. This is nonsensical, as we can just use a THREAD_SIZE offset from the init_thread_union instead (as every other arch does). Signed-off-by: -

in_nmi shifted down a few labels, so we were inadvertently clearing the lower byte of do_syscall_trace, badness ensues. Signed-off-by: -

Move the syscall table in to its own file, as per sh64. The entry.S bits will end up being considerably different in the sh2/sh2a cases, so this lets us keep things in sync somewhat.. Signed-off-by: -

Fix use of uninitialized spinlocks, caught with spinlock debugging.. Signed-off-by: -
Paul Mundt authored
flush_cache_range() wasn't page aligning the end of the range, we can't assume that it will always be page aligned, and we ended up getting unaligned faults in some rare call paths. Additionally, we add a small optimization to just purge the dcache entirely if the range is large enough that the page table walking will take longer. We use an arbitrary value of 64 pages for the large range size, as per sh64. Signed-off-by: -

Convert cmm's usage of kernel_thread to kthread_run. Also create the cmmthread at module load time, so it is possible to check if creation of the thread fails. In addition the cmmthread now gets terminated when the module gets unloaded instead of leaving a stale kernel thread. Also check the return values of other registration functions at module load and handle their return values appropriately. Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by:

Include the host architecture's ptrace-abi.h instead of ptrace.h. There was some cpp mangling of names around the ptrace.h include to avoid symbol clashes between UML and the host architecture. Most of these can go away. The exception is struct pt_regs, which is convenient to have in userspace, but must be renamed in order that UML can define its own. ptrace-x86_64.h needed to have some now-obsolete cpp cruft and a declaration removed.

The use of SEGMENT_RPL_MASK in the i386 ptrace.h introduced by x86-allow-a-kernel-to-not-be-in-ring-0.patch broke the UML build, as UML includes the underlying architecture's ptrace.h, but has no easy access to the x86 segment definitions. Rather than kludging around this, as in the past, this patch splits the userspace-usable parts, which are the bits that UML needs, of ptrace.h into ptrace-abi.h, which is included back into ptrace.h. Thus, there is no net effect on i386. As a side-effect, this creates a ptrace header which is close to being usable in /usr/include. x86_64 is also treated in this way for consistency. There was some trailing whitespace there, which is cleaned up. Signed-off-by:

The KSTK_* macros used an inordinate amount of stack. In order to overcome an impedance mismatch between their interface, which just returns a single register value, and the interface of get_thread_regs, which took a full pt_regs, the implementation created an on-stack pt_regs, filled it in, and returned one field. do_task_stat calls KSTK_* twice, resulting in two local pt_regs, blowing out the stack. This patch changes the interface (and name) of get_thread_regs to just return a single register from a jmp_buf. The include of archsetjmp.h" in registers.h to get the definition of jmp_buf exposed a bogus include of <setjmp.h> in start_up.c. <setjmp.h> shouldn't be used anywhere any more since UML uses the klibc setjmp/longjmp.

timer_irq_inited was useless, so it is removed. Signed-off-by:

Jeff Dike authored
set_interval returns an error instead of panicing if setitimer fails. Some of its callers now check the return. enable_timer is largely tt-mode-specific, so it is marked as such, and the only skas-mode caller is made to call set-interval instead. user_time_init was a no-value-added wrapper around set_interval, so it is gone. Since set_interval is now called from kernel code, callers no longer pass ITIMER_* to it. Instead, they pass a flag which is converted into ITIMER_REAL or ITIMER_VIRTUAL. Signed-off-by:

Have most signals go through an arch-provided handler which recovers the sigcontext and then calls a generic handler. This replaces the ARCH_GET_SIGCONTEXT macro, which was somewhat fragile. On x86_64, recovering %rdx (which holds the sigcontext pointer) must be the first thing that happens. sig_handler duly invokes that first, but there is no guarantee that I can see that instructions won't be reordered such that %rdx is used before that. Having the arch provide the handler seems much more robust. Some signals in some parts of UML require their own handlers - these places don't call set_handler any more. They call sigaction or signal themselves. Signed-off-by:

- Various cleanups in the sigio code. - Removed explicit zero-initializations of a few structures. - Improved some error messages. - An API change - there was an asymmetry between reactivate_fd calling maybe_sigio_broken, which goes through all the machinery of figuring out if a file descriptor supports SIGIO and applying the workaround to it if not, and deactivate_fd, which just turns off the descriptor. This is changed so that only activate_fd calls maybe_sigio_broken, when the descriptor is first seen. reactivate_fd now calls add_sigio_fd, which is symmetric with ignore_sigio_fd. This removes a recursion which makes a critical section look more critical than it really was, obsoleting a big comment to that effect. This requires keeping track of all descriptors which are getting the SIGIO treatment, not just the ones being polled at any given moment, so that reactivate_fd, through add_sigio_fd, doesn't try to tell the SIGIO thread about descriptors it doesn't care about.
