commit 41d479ceb0269ff18999e8332d82ea73cf6a8115

Rename sys/ucontext.h to bits/ucontext.h
sys/ucontext.h is effectively a bits header. Its contents are
extremely system-specific, and it’s strongly associated with a
specific public header (ucontext.h) that provides a superset of its
definitions, but there are other public headers that also require some
of its definitions. This patch therefore moves it into the bits/
namespace and adjusts all the headers that refer to it. In case there
are external users, a stub is added that includes ucontext.h.
Most of the fallout changes are trivial, but ia64 and riscv need a
little more work. ia64 bits/ptrace.h and bits/procfs.h were both
including bits/sigcontext.h, which is only licensed to be included
from signal.h. (I’m not sure how this ever worked, or why it broke
with this patch and not some previous one.) This is fixed by creating
another single-type header, bits/types/__ia64_fpreg.h, which provides
the only thing they need from bits/sigcontext.h.
s/u/s/l/riscv/makecontext.c was defining makecontext with a function
head that didn’t agree with its official prototype (in ucontext.h);
formerly that file did not include ucontext.h, only sys/ucontext.h,
so we were getting away with it, but it’s still wrong. Making the
function head match the prototype actually simplifies the code.

commit 536eef52c5c6bae9939aa5b591b914273e731a13
Author: Zack Weinberg <zackw@panix.com>
Date: Tue Jun 11 13:05:02 2019 -0400
Rename sys/ucontext.h to bits/ucontext.h.
sys/ucontext.h is effectively a bits header. Its contents are
extremely system-specific, and it’s strongly associated with a
specific public header (ucontext.h) that provides a superset of its
definitions, but there are other public headers that also require some
of its definitions. This patch therefore moves it into the bits/
namespace and adjusts all the headers that refer to it. In case there
are external users, a stub is added that includes ucontext.h.
Most of the fallout changes are trivial, but aarch64, ia64 and riscv
need a little more work. aarch64 sys/ucontext.h (now bits/ucontext.h)
was including sys/procfs.h for the definition of elf_greg_t etc;
the simplest fix is to have it include bits/procfs.h instead (and then
that needs to include sys/user.h for user_regs_struct). This is not
ideal but fixing it properly would require disentangling all of the
debugger interface headers which is more than I’m up for at the moment.
ia64 bits/ptrace.h and bits/procfs.h were both including
bits/sigcontext.h, which is only licensed to be included from
signal.h. (I’m not sure how this ever worked, or why it broke with
this patch and not some previous one.) This is fixed by creating
another single-type header, bits/types/__ia64_fpreg.h, which provides
the only thing they need from bits/sigcontext.h.
s/u/s/l/riscv/makecontext.c was defining makecontext with a function
head that didn’t agree with its official prototype (in ucontext.h);
formerly that file did not include ucontext.h, only sys/ucontext.h,
so we were getting away with it, but it’s still wrong. Making the
function head match the prototype actually simplifies the code.

commit 4e187c73778d8201138ae5b0ca687d3a765b65f8
Author: Zack Weinberg <zackw@panix.com>
Date: Tue Jun 11 13:05:02 2019 -0400
Rename sys/ucontext.h to bits/ucontext.h.
sys/ucontext.h is effectively a bits header. Its contents are
extremely system-specific, and it’s strongly associated with a
specific public header (ucontext.h) that provides a superset of its
definitions, but there are other public headers that also require some
of its definitions. This patch therefore moves it into the bits/
namespace and adjusts all the headers that refer to it. In case there
are external users, a stub is added that includes ucontext.h.
Most of the fallout changes are trivial, but aarch64, ia64 and riscv
need a little more work. aarch64 sys/ucontext.h (now bits/ucontext.h)
was including sys/procfs.h for the definition of elf_greg_t etc;
the simplest fix is to have it include bits/procfs.h instead (and then
that needs to include sys/user.h for user_regs_struct). This is not
ideal but fixing it properly would require disentangling all of the
debugger interface headers which is more than I’m up for at the moment.
ia64 bits/ptrace.h and bits/procfs.h were both including
bits/sigcontext.h, which is only licensed to be included from
signal.h. (I’m not sure how this ever worked, or why it broke with
this patch and not some previous one.) This is fixed by creating
another single-type header, bits/types/__ia64_fpreg.h, which provides
the only thing they need from bits/sigcontext.h.
s/u/s/l/riscv/makecontext.c was defining makecontext with a function
head that didn’t agree with its official prototype (in ucontext.h);
formerly that file did not include ucontext.h, only sys/ucontext.h,
so we were getting away with it, but it’s still wrong. Making the
function head match the prototype actually simplifies the code.

Rename sys/ucontext.h to bits/ucontext.h.
sys/ucontext.h is effectively a bits header. Its contents are
extremely system-specific, and it’s strongly associated with a
specific public header (ucontext.h) that provides a superset of its
definitions, but there are other public headers that also require some
of its definitions. This patch therefore moves it into the bits/
namespace and adjusts all the headers that refer to it. In case there
are external users, a stub is added that includes ucontext.h.
Most of the fallout changes are trivial, but aarch64, ia64 and riscv
need a little more work. aarch64 sys/ucontext.h (now bits/ucontext.h)
was including sys/procfs.h for the definition of elf_greg_t etc;
the simplest fix is to have it include bits/procfs.h instead (and then
that needs to include sys/user.h for user_regs_struct). This is not
ideal but fixing it properly would require disentangling all of the
debugger interface headers which is more than I’m up for at the moment.
ia64 bits/ptrace.h and bits/procfs.h were both including
bits/sigcontext.h, which is only licensed to be included from
signal.h. (I’m not sure how this ever worked, or why it broke with
this patch and not some previous one.) This is fixed by creating
another single-type header, bits/types/__ia64_fpreg.h, which provides
the only thing they need from bits/sigcontext.h.
s/u/s/l/riscv/makecontext.c was defining makecontext with a function
head that didn’t agree with its official prototype (in ucontext.h);
formerly that file did not include ucontext.h, only sys/ucontext.h,
so we were getting away with it, but it’s still wrong. Making the
function head match the prototype actually simplifies the code.

commit fd937b61650f992c03f72bf4569eb491ca9d2c65
Author: Zack Weinberg <zackw@panix.com>
Date: Tue Jun 25 16:18:31 2019 -0400
Rename sys/ucontext.h to bits/ucontext.h.
sys/ucontext.h is effectively a bits header. Its contents are
extremely system-specific, and it’s strongly associated with a
specific public header (ucontext.h) that provides a superset of its
definitions, but there are other public headers that also require some
of its definitions. This patch therefore moves it into the bits/
namespace and adjusts all the headers that refer to it. In case there
are external users, a stub is added that includes ucontext.h.
Most of the fallout changes are trivial, but aarch64, ia64 and riscv
need a little more work. aarch64 sys/ucontext.h (now bits/ucontext.h)
was including sys/procfs.h for the definition of elf_greg_t etc;
the simplest fix is to have it include bits/procfs.h instead (and then
that needs to include sys/user.h for user_regs_struct). This is not
ideal but fixing it properly would require disentangling all of the
debugger interface headers which is more than I’m up for at the moment.
ia64 bits/ptrace.h and bits/procfs.h were both including
bits/sigcontext.h, which is only licensed to be included from
signal.h. (I’m not sure how this ever worked, or why it broke with
this patch and not some previous one.) This is fixed by creating
another single-type header, bits/types/__ia64_fpreg.h, which provides
the only thing they need from bits/sigcontext.h.
s/u/s/l/riscv/makecontext.c was defining makecontext with a function
head that didn’t agree with its official prototype (in ucontext.h);
formerly that file did not include ucontext.h, only sys/ucontext.h,
so we were getting away with it, but it’s still wrong. Making the
function head match the prototype actually simplifies the code.

commit 52c44a2a8e5598cea3f66038bd5506e0b5eab9f7
Author: Zack Weinberg <zackw@panix.com>
Date: Tue Jun 11 13:05:02 2019 -0400
Rename sys/ucontext.h to bits/ucontext.h.
sys/ucontext.h is effectively a bits header. Its contents are
extremely system-specific, and it’s strongly associated with a
specific public header (ucontext.h) that provides a superset of its
definitions, but there are other public headers that also require some
of its definitions. This patch therefore moves it into the bits/
namespace and adjusts all the headers that refer to it. In case there
are external users, a stub is added that includes ucontext.h.
Most of the fallout changes are trivial, but ia64 and riscv need a
little more work. ia64 bits/ptrace.h and bits/procfs.h were both
including bits/sigcontext.h, which is only licensed to be included
from signal.h. (I’m not sure how this ever worked, or why it broke
with this patch and not some previous one.) This is fixed by creating
another single-type header, bits/types/__ia64_fpreg.h, which provides
the only thing they need from bits/sigcontext.h.
s/u/s/l/riscv/makecontext.c was defining makecontext with a function
head that didn’t agree with its official prototype (in ucontext.h);
formerly that file did not include ucontext.h, only sys/ucontext.h,
so we were getting away with it, but it’s still wrong. Making the
function head match the prototype actually simplifies the code.
* sysdeps/generic/sys/ucontext.h: Move to top level bits/ucontext.h.
Adjust multiple inclusion guard.

commit 9370e5520fa8bbab8ac1690e603bc13559672184
Author: Zack Weinberg <zackw@panix.com>
Date: Tue Jun 11 13:05:02 2019 -0400
Rename sys/ucontext.h to bits/ucontext.h.
sys/ucontext.h is effectively a bits header. Its contents are
extremely system-specific, and it’s strongly associated with a
specific public header (ucontext.h) that provides a superset of its
definitions, but there are other public headers that also require some
of its definitions. This patch therefore moves it into the bits/
namespace and adjusts all the headers that refer to it. In case there
are external users, a stub is added that includes ucontext.h.
Most of the fallout changes are trivial, but ia64 and riscv need a
little more work. ia64 bits/ptrace.h and bits/procfs.h were both
including bits/sigcontext.h, which is only licensed to be included
from signal.h. (I’m not sure how this ever worked, or why it broke
with this patch and not some previous one.) This is fixed by creating
another single-type header, bits/types/__ia64_fpreg.h, which provides
the only thing they need from bits/sigcontext.h.
s/u/s/l/riscv/makecontext.c was defining makecontext with a function
head that didn’t agree with its official prototype (in ucontext.h);
formerly that file did not include ucontext.h, only sys/ucontext.h,
so we were getting away with it, but it’s still wrong. Making the
function head match the prototype actually simplifies the code.
* sysdeps/generic/sys/ucontext.h: Move to top level bits/ucontext.h.
